Abstract

The present invention provides a lock cylinder structure with automatic locking after damage, which includes: a lock body with two lock cylinders, where the lock body has a cam positioned between the two lock cylinders, and a driving block situated between the lock cylinder and the cam, with a limiting component inside the driving block; a transmitter is installed within the driving block, which transmits motion axially in alignment with each other; the side edge of the transmitter is equipped with a driving block, which features a radially recessed moving groove and a limiting unit on one side; one end of the lock cylinder has a driving plate, which is aligned and connected to the driving block; the driving plate is coupled with a driving rod, which includes a driving pin, and the driving pin is slidable engaged in the moving groove of the transmitter; thus, when one end of the lock cylinder is damaged and removed, the lock cylinder will be manually pulled out, simultaneously axially driving out the driving plate, driving rod, and driving pin, causing the driving pin to actuate the transmitter and in turn, pulling the transmitter at the other end. This action results in the limiting unit of the other end's transmitter aligning with its corresponding limiting component and automatically locking, thus providing axial limitation. Additionally, the driving block at the other end extends into the cam's sliding groove, preventing the lock cylinder from being unlocked by only rotating the driving block and cam at the damaged end. As the driving block is manually pulled out by the tamper, and the locking end is on the side opposite the damaged one, the automatic locking mechanism cannot be compromised through tapping, thus achieving excellent anti-theft protection. Meanwhile, the lock cylinder at the other end can still be unlocked via its transmitter acting on the cam, ensuring that the lock body does not become locked due to the damage at one end.

Description

Lock core structure that automatically locks after being damaged

The present invention provides a lock core structure that automatically locks after being damaged, and in particular, refers to a lock core structure that, after the lock core at one end of the lock body is damaged, can cause the actuator at the other end to be locked and extend into the cam when the damaged lock core is pulled out, so that the damaged end cannot be unlocked but can only run idle, which can effectively prevent the mechanism from causing the lock to fail due to misalignment of components caused by knocking, while the lock core at the undamaged end can still be unlocked by its actuator driving the cam.

According to the commonly used locks, the upper and lower beads in the lock core are usually used to achieve the locking and anti-theft effects. Generally speaking, the common theft method used by thieves is to fiddle with the upper and lower beads in the lock core to make them in the unlocking position, so as to rotate the cam to open the lock. However, if the arrangement of the upper and lower beads in the lock base and the lock core is too complicated, it will be difficult to fiddle with the upper and lower beads to make them in the unlocking position. At this time, thieves can still directly destroy the lock seat from the outside to break the connection between the lock seat and the lock core, thereby taking out the lock core, and then directly turning the cam to unlock the lock. This method can still unlock the lock within a few minutes. Therefore, no matter how complicated the lock core is, if the force used by the thieves to destroy the lock is greater than the rigidity of the lock seat, the lock seat can be destroyed and the lock core can be taken out. Therefore, its anti-theft performance is still insufficient.

Some existing highly anti-theft locks further have a mechanism that can automatically lock after the lock core is destroyed. This is mainly achieved by providing a radial limit element on the lock body or cam of the lock, and configuring a spring inside the lock. Correspondingly, an assembly hole corresponding to the limit element is provided on the internal element, such as the cam or the rotating wheel. When one end of the lock core is destroyed, the assembly hole at the destroyed end can be aligned with the limit element when the lock core is removed, so that the lock core is automatically locked and cannot be unlocked.

Furthermore, a transmission element is arranged inside the cam or the wheel. The cam or the wheel can be equipped with the aforementioned limiting element, and the transmission element is equipped with a corresponding assembly hole. The transmission elements are pressed against each other through an elastic element. When the lock core at one end is damaged, the lock core cannot push against the transmission element, so the elastic element will push the transmission element axially. However, some of the aforementioned automatic locking mechanisms can still be cracked by tapping the lock core, so that the spring or elastic element cannot operate due to temporary misalignment, thereby invalidating the automatic locking mechanism, so that the cam can still be rotated to unlock.

In order to comply with the safety escape regulations, the lock core of the undamaged end can still be unlocked, so the automatic locking mechanism is usually on the same side as the damaged end. Furthermore, the alignment locking of the assembly hole and the limit element is mostly transmitted by elastic elements. Therefore, by knocking, the elastic element and the spring can be directly misaligned temporarily and cannot be repositioned elastically, making the automatic locking method invalid. Therefore, the use of locks with automatic locking still cannot ensure its effectiveness during operation.

In view of this, we, the inventors, have devoted ourselves to further researching a lock that can be automatically locked when damaged, and can still be effectively automatically locked when struck, and the lock core at the other end can still be unlocked. We have also started to research and develop and improve its structural configuration, hoping to find a better invention to solve the above problems.

From the above description and configuration, it is apparent that the present invention mainly has the following advantages and effects, which are described in detail as follows:

1. The invention adopts the linkage configuration between the actuator, the transmission pin, the transmission rod, the transmission plate and the lock core, and the two actuators are also synchronously linked and assembled. When in the normal position, the different actuators are directly or indirectly against each other in the through slot, and when one of the actuators enters the through slot of the cam, the actuator at the other end can be pushed out of the through slot; and when the lock core at either end is damaged, the invention utilizes the mechanism that the damage force will inevitably remove the lock core, so that the thief When the lock core is pulled, the actuator will be pulled through its transmission plate, transmission rod, and transmission pin. At the same time, since the actuators are also connected to each other, the actuator at the other end will also be pulled, so that the limit unit of the actuator at the other end is located at the limit assembly of the corresponding driving block and connected to each other, so that the actuator at the other end is limited in the axial direction and automatically locked. At the same time, the driving block at the other end is correspondingly extended into the slide groove of the cam, and the damaged end The transmission block is pushed out of the slide slot, so that the transmission and driven block at the damaged end can only rotate idly in the cam, and cannot rotate the cam to unlock; therefore, even if the thief cracks the door by knocking, since the distance between the other end of the transmission and the damaged end is farther, and it is blocked by the cam, driven block and transmission and its internal contour, the vibration of the knocking will be blocked by layers of components and it is extremely difficult to be transmitted to the transmission and its limit assembly at the other end. Moreover, the axial movement of the actuator is mainly driven by human power, so it can be ensured that it can be accurately aligned and automatically locked when being pulled, so that an excellent anti-theft effect can be achieved; and since the driving block of the actuator at the other end that is damaged is located in the through groove of the cam, it can still be unlocked by a correct key, and the lock body will not be locked due to the damage of the lock core at one end; thereby, the applicable occasions of the present invention can be improved, thereby enhancing the overall applicability of the present invention.

2. The drive block and the actuator of the damaged end of the lock core of the present invention cannot be removed by the cam due to the setting of the limit plate and the stop member, and still form an idle rotation with the cam, thereby protecting the actuator at the other end and preventing it from being cracked by external force.

3. The present invention can accurately locate the position of the cam through the setting of the positioning ring to prevent the lock core from being damaged by external force and its force impacting the cam and causing displacement. It can ensure that when the lock core at one end is damaged by external force and removed, the actuator at the other end can be smoothly pulled, and its limit unit can be accurately positioned and assembled by the limit assembly, so as to ensure the effectiveness of the automatic locking function of the present invention.

4. The different lock cores of the present invention may be arranged in the same or different ways; and the different actuators, drive blocks and other components may be arranged in the same or different ways; and when both sides are arranged in the same way, the number of components of different configurations required for production can be greatly reduced, thereby effectively saving the cost of mold development, and during assembly, because of the symmetrical arrangement of the same structure, the difficulty of assembly can be reduced, and the assembly man-hours can be reduced, thereby improving the overall manufacturing efficiency of the present invention.

Regarding the technical means of our inventors, several preferred embodiments are described in detail below with reference to the drawings so that you can have a deeper understanding and recognize the present invention.

Please refer to Figures 1 to 3. The present invention is a lock core structure that automatically locks after being destroyed, which includes:

A lock body 1 is provided with two lock cores 2, and the lock body 1 has a cam 3 between the lock cores 2. It is known that the lock body 1 is used to be installed on a partition object (not shown), such as a door, and the cam 3 is used to achieve the purpose of partitioning the object to prevent theft. In an embodiment, the lock core 2 can be rotated only by a correct key 8. Its setting belongs to the known technology, so it will not be elaborated here, and the setting form of the lock core 2 is only for example description, and it is not used as a limitation.

The lock core 2 is provided with a driving block 4 at one end corresponding to the cam 3 in the rotation direction, and the driving block 4 is provided with a driving groove 41 in the axial direction, and a connecting groove 42 corresponding to the driving groove 41 is provided in the radial direction, and a limiting assembly 43 is provided in each connecting groove 42;

The two actuators 5 are respectively arranged in the transmission grooves 41 of the driving block 4, and the actuators 5 are connected to each other in the axial direction. In one embodiment, the actuators 5 can be directly connected in the axial direction. In order to facilitate the connection and the reliability of the axial transmission, it is preferred that the corresponding ends of the actuators 5 are further provided with a convex connection portion 51. The actuators 5 are connected to each other through the convex parts 51, and the convex parts 51 are concavely provided with a groove 511 on the side edge, and can pass through a buckle element 52, which has two ring parts 521, and the ring parts 521 are buckled in the grooves 511 respectively, so that the actuators 5 can be synchronously displaced in the axial direction. However, the assembly method is only an example for explanation and is not limited thereto;

The side edge of the actuator 5 is provided with a transmission block 53 corresponding to the transmission groove 41, and a moving groove 54 and a limiting unit 55 corresponding to the assembly groove 42 are radially recessed on one side; the moving groove 54 is provided along the axial direction of the actuator 5;

The cam 3 is provided with a through slot 31 corresponding to the driver 5, and the through slot 31 is provided with slide grooves 311 corresponding to the drive block 53 in the radial direction; specifically, the cam 3 is provided with a recessed portion 32 at both ends, and the drive block 4 is arranged in the recessed portion 32, and the bottom wall of the recessed portion 32 in the axial direction forms a concave surface 321, and the through slot 31 and the slide groove 311 are formed on the concave surface 321; the slide groove 3 11 is configured so that the driving block 53 can be displaced in the axial direction and can drive the cam 3 to rotate in the rotational direction; therefore, when the lock core 2 is rotated by the correct key 8, it will directly drive the driving block 4 to rotate, and then drive the driving block 53 of the actuator 5 through the transmission groove 41. When the driving block 53 is located in the slide groove 311 of the cam 3, it can drive the cam 3 to rotate through the slide groove 311, thereby unlocking or locking the door body;

The lock core 2 is fixedly provided with a transmission plate 6 at one axial end, and the transmission plate 6 is correspondingly connected to the driving block 4. In one embodiment, the transmission plate 6 is arranged in an arc-shaped plate to increase the transmission torque of the lock core 2 to the driving block 4. In cold weather, since a heater is usually installed indoors, if the door body is deformed due to the temperature difference between indoors and outdoors, the door body can be heated and contracted by the temperature difference between indoors and outdoors. The transmission plate 6 is configured in an arc shape, which makes it easier for the user to rotate the lock core 2 to unlock, thereby improving the convenience and applicability of the present invention when unlocking. However, this is only an example and is not intended to be limiting. The transmission plate 6 is assembled with a transmission rod 7, and the transmission rod 7 is radially provided with a transmission pin 71, and the transmission pin 71 is correspondingly slidably connected in the moving groove 54 of the transmission 5;

The distance between the assembly slots 42 of the different driving blocks 4 is smaller than the distance between the stopper units 55 of the different actuators 5; and the position between the assembly slots 42 is located within the distance between the stopper units 55; thereby, when used in a normal position, as shown in FIG. 4 and FIG. 5, the different actuators 5 directly or indirectly abut against each other in the through slot 31, and the stopper units 55 are not opposite to the stopper assembly 43; and in this case In order to maintain the position of the actuator 5 without axial movement, it is preferred, as shown in FIG. 2 and FIG. 5, that an axial hole 21 is recessed in the lock core 2 at a position corresponding to the actuator 5, and an elastic element 211 and a push pin 212 are accommodated in the axial hole 21. The elastic element 211 elastically presses against the push pin 212, so that the push pin 212 presses against the actuator 5 in the corresponding axial direction, so as to position the actuator 5;

When the key 8 is correctly inserted, as shown in FIG. 6 and FIG. 7 , the end of the key 8 will axially push the actuator 5, and the range of its pushing is only to move the drive block 53 into the slide groove 311 of the cam 3. Therefore, when the key 8 rotates, the lock core 2 will also rotate at the same time. As mentioned above, the lock core 2 will be driven by the drive plate 6 to drive the drive block 4 to rotate, and then through the transmission groove 41 to drive the drive block 53 of the actuator 5. It is located in the slide groove 311 of the cam 3, so the cam 3 can be driven to rotate through the slide groove 311 to unlock or lock the door. It should be noted that when the lock core 2 is not damaged, the actuator 5 at one end of the key 8 or the actuator 5 at the other end will not be able to align with the assembly groove 42 because the distance between the belt assembly grooves 42 is smaller than the distance between the limit units 55. Therefore, the limit units 55 of the actuators 5 at both ends cannot be locked.

It can be known that another purpose of setting the transmission pin 71 is that, in the normal position, since the lock core 2 is not removed, the position of the transmission pin 71 is fixed, which can play a role in axially limiting the actuator 5. Therefore, in the normal position, the spacing of the transmission pin 71 is also smaller than the spacing of the limiting unit 55, so that even if the actuator 5 is pushed excessively, the moving groove 54 of the actuator 5 at the other end will be limited by the transmission pin 71 at the other end, so that the limiting unit 55 will not be aligned with the assembly groove 42 and locked, thereby ensuring that the protection and safety measures of the present invention can be effectively operated under normal use.

Among them, for the fixing, connection and transmission configuration of the transmission plate 6 and the transmission rod 7, the driving block 4 is further axially recessed with an arc groove 44 corresponding to the transmission plate 6, and a connecting groove 45 corresponding to the transmission rod 7, and the arc groove 44, the connecting groove 45 and the transmission groove 41 are interconnected in the radial direction. Therefore, in a normal state, the transmission rod 7 is buried in the connecting groove 45 and can be axially positioned by the transmission plate 6 assembled in the arc groove 44. At the same time, the transmission pin 71 can achieve the aforementioned axial limiting effect.

As for the assembly of the transmission rod 7 and the transmission plate 6, as shown in Figures 2 and 4, the transmission rod 7 is further provided with a slot 72 at one end of the transmission plate 6, and the transmission rod 7 is radially provided with a through hole 73 corresponding to the slot 72, the transmission plate 6 is assembled to the slot 72, and the transmission plate 6 is provided with an assembly hole 61 corresponding to the through hole 73; the assembly hole 61 of the transmission plate 6 and the through hole 73 of the slot 72 are respectively positioned and transmitted to each other through a set of connecting pins 62, and it can be known that since the transmission rod 7 is buried in the connecting groove 45, the assembly pin 62 will also be synchronously positioned in the driving block 4, so that the transmission rod 7 and the transmission plate 6 can be effectively and stably assembled and positioned.

As for the connection between the transmission plate 6 and the lock core 2, as shown in FIG. 2, the lock core 2 is provided with a transmission groove 22 corresponding to the transmission plate 6, and the lock core 2 is radially provided with at least one fixing hole 221 corresponding to the transmission groove 22. In this embodiment, the transmission plate 6 can be provided with two pins 63 at one end of the lock core 2, and the transmission plate 6 is provided with a positioning hole 631 corresponding to the fixing hole 221, and the positioning hole 631 is respectively provided at the pin 63, and the positioning hole 631 of the transmission plate 6 and the positioning hole 631 of the lock core 2 are respectively provided. The fixing holes 221 are respectively positioned and driven by a fixing pin 64. It is known that the lock body 1 can accommodate the lock ball by configuring a sleeve 11 at both ends, and the lock core 2 is correspondingly configured in the sleeve 11. The configuration relationship of the lock ball is a known technology and is not the main subject of the present invention, so the configuration structure is not described in detail. As for the radial positioning of the fixing pin 64, it can be blocked by the wall surface in the sleeve 11, so that the lock core 2 can be correspondingly assembled with the transmission plate 6, and the transmission plate 6 can be synchronously actuated together with the lock core 2.

In the normal position, when the position of the limit unit 55 is not aligned with the assembly slot 42 and the limit assembly 43, it is not locked; and its specific configuration, in this embodiment, is to configure the limit unit 55 as a slightly rectangular recess, and the limit assembly 43 includes a stop block 431, a positioning block 432 and at least one elastic unit 433, and the elastic unit 433 is elastically pressed against the stop block 431 and the positioning block 432. The stop block 431 is arranged in a shape corresponding to the limit unit 55, and the positioning block 432 is in contact with the inner wall surface of the recessed portion 32 of the cam 3 and elastically presses against the corresponding stop block 431; and in the normal position, as shown in FIG. 8, since the position of the limit unit 55 is not aligned with the assembly groove 42 and its limit assembly 43, the stop block 431 presses against the side edge of the actuator 5 and is in an unlocked state.

When it is in a damaged position, the lock body 1, the bushing 11 or the lock core 2 at one end may be damaged by external force, so that the lock core 2 can be directly taken out by external force. At this time, as shown in Figures 9 and 10, in response to the lock core 2 being taken out, the transmission plate 6, the transmission rod 7 and the transmission pin 71 will be pulled out axially at the same time, so that the transmission pin 71 passes through the moving groove 54 to pull the transmission 5 in response, and then pulls the transmission 5 at the other end at the same time, so that the limit unit 55 of the transmission 5 at the other end is mutually connected with the limit assembly 43 of the corresponding driving block 4, so that the transmission 5 at the other end is axially moved. The stop block 431 is automatically locked by limiting the position, as described above and as shown in Figures 9 and 11, and is elastically supported by the elastic unit 433 and assembled in the corresponding limiting unit 55. At the same time, as shown in Figure 10, the transmission block 53 at the other end is correspondingly extended into the slide groove 311 of the cam 3, and the transmission block 53 at the damaged end is pushed out of the slide groove 311. Therefore, the transmission 5 and the driving block 4 of the lock core 2 at the damaged end can only idle and cannot be transmitted to the cam 3, so as to achieve the effect that the other end of the damaged end can be automatically locked, so that the damaged end cannot be unlocked.

Therefore, preferably, the transmission pin 71 and the moving groove 54 are arranged so that when the end of the moving groove 54 relative to the other actuator 5 contacts the transmission pin 71, the limit unit 55 corresponds to the position of the limit assembly 43, thereby ensuring that after the lock core 2 is pulled by the damaged end, it can be automatically locked as described above.

As for the positioning between the driving block 4 and the cam 3, a concave ring portion 46 is radially concavely provided on the outer edge of the driving block 4, and a fixing groove 33 is respectively concavely provided on the outer edge of the cam 3 at a position corresponding to the concave ring portion 46, and a through groove 34 is respectively radially penetrated in the fixing groove 33; two limiting plates 35 are respectively assembled in the through groove 34 and abut against the The concave ring portion 46; and two positioning rings 36, which are respectively assembled and connected to the fixing groove 33, and correspondingly press against the limit plate 35; thereby, the driving block 4 can rotate correspondingly to the cam 3, and can drive the cam 3 when the driving block 53 of the transmission 5 extends into the sliding groove 311, otherwise, it will idle correspondingly to the cam 3; and its configuration will make the driving block 4 in the breaking position In the state of being placed, it will be impossible to remove the cam 3. In addition, the lock body 1 is usually buried in the door body, so the positioning ring 36 will be buried deep in the partition object and cannot be seen. In addition, the lock body 1 is usually equipped with a connecting rod 12 on both sides for installing the bushing 11, and the connecting rod 12 has the characteristic of being easily broken, resulting in the bushing 11 and the lock being broken when the position is damaged. The core 2 can be easily taken out to achieve the aforementioned automatic locking effect. Therefore, at this time, unless the door body is destroyed as a whole, the positioning ring 36 cannot be further removed. The limiting piece 35 will still be located at the concave ring portion 46, so that the driving block 4 can only rotate idly and be axially positioned on the cam 3, and the driving block 4 cannot be taken out to prevent it from being knocked and cracked, thereby greatly improving the anti-theft property of the present invention.

As for the positioning method of the positioning ring 36, in order to enhance its stability during positioning and to accurately position the cam 3 so as to ensure that the automatic locking mechanism of the present invention can operate effectively, it is preferred that the positioning ring 36 is further provided with a connecting portion 361 at one end corresponding to the lock body 1, and the connecting portion 361 is respectively connected to a connecting piece 13; and the lock body 1 is provided with two The positioning grooves 14 are respectively assembled with the connecting pieces 13, and the lock body 1 is further provided with at least one hole groove 15 corresponding to the positioning groove 14 at one end corresponding to the lock core 2; and a plurality of latches 151 are respectively assembled with the hole groove 15 and the positioning groove 14, and are correspondingly assembled with the connecting portion 361, so as to form a stable fixed position for the positioning ring 36.

As for the positioning of the actuator 5 in the driving block 4, a limiting groove 56 is further concavely provided on one side of the actuator 5, and the driving block 4 is provided with a limiting hole 47 corresponding to the limiting groove 56; the limiting hole 47 is respectively provided with a stopper 471, and the stopper 471 is correspondingly extended into the limiting groove 56 to limit the axial movement distance of the actuator 5; and it can be known that, as the driving block 4 is extended into and arranged in the recessed portion 32 of the cam 3 as mentioned above, The radial direction of the stop member 471 will be fixed by the cam 3. As mentioned above, since the driving block 4 cannot be removed from the cam 3, the setting of the stop member 471 will also prevent the transmission device 5 from being removed from the driving block 4 and the cam 3. With this setting, the driving block 4 and the transmission device 5 at one end can be destroyed, and the setting of the concave surface 321 can effectively and completely shield the driving block 4 and the transmission device 5 at the other end, which can effectively prevent them from being cracked by knocking, thereby enhancing the overall anti-theft property of the present invention.

With this arrangement, even if the existing cracking method of knocking the lock core 2 is adopted, as mentioned above, firstly, the locking mechanism of the present invention is mainly to pull out the lock core 2 manually after the lock core 2 is broken, and the actuator 5 at the other end will be pulled at the same time to lock, and the force applied by manually pulling out the lock core 2 is extremely large, so the operation of the actuator 5 will not be affected by misalignment, and therefore it will not be cracked by knocking; in addition, as far as the arrangement of the limit assembly 43 is concerned, although it still has the elastic unit 433, as mentioned above, one end of the automatic locking of the present invention is relatively broken. Furthermore, the present invention can completely shield the driving block 4 and the actuator 5 at the other end through the positioning arrangement of the aforementioned driving block 4, the actuator 5, and the concave surface 321 of the cam 3. Therefore, even if a tool or knocking method is used to damage one end, it will be shielded by the cam 3 and the driving blocks 4 and the actuator 5 at both ends, and it will not be possible to enter the limit assembly 43 at the other end. Therefore, the cracking method is ineffective for the limit assembly 43. Therefore, the present invention does have an excellent anti-theft effect, prevents various types of vandalism, and can maintain its automatic locking effect.

What needs to be particularly explained is that, as shown in Figures 9 and 10, when the automatic locking mechanism is activated in the aforementioned damaged position while the other end is intact, the actuator 5 at the undamaged end and the cam 3 are locked by the limit unit 55 and the current assembly, and its transmission block 53 has been extended into the slide groove 311 of the cam 3. Therefore, when the lock core 2 at the undamaged end is inserted with the correct key 8 and the lock core 2 is rotated, it can still be unlocked through its transmission plate 6, the driving block 4 and the actuator 5 to transmit to the cam 3, so that the user of the undamaged end will not be locked due to the damage to the other end, so that the other end can still be used for entry and exit or escape safety.

It should be further explained that the two different lock cores of the present invention may be arranged in the same or different manner; and the actuators 5, the drive blocks 4 and other components located on both sides of the lock body 1 may be arranged in the same or different manner; and when the actuators 5, the drive blocks 4 and other components on both sides are arranged in the same manner, the number of components of different configurations required for production can be greatly reduced, thereby effectively saving the development cost of the mold, and during assembly, because they have the same symmetrical arrangement of the same structure, the difficulty of assembly can be reduced, and the assembly time can be reduced, so as to improve the overall manufacturing efficiency of the present invention; and the arrangement of the cam 3 in the direction of its slide groove 311 , and in response to the transmission block 53 of the transmission device 5 being in the same arrangement but in opposite directions at different installation positions, the two sides may be arranged in opposite directions, while the through slot 31 is still arranged in a corresponding connection; in addition, as for the configuration of the lock core 2, it may be an external configuration with the same or different number of lock code groups and transmission structure, or it may only have an external configuration with the same transmission structure but different number of lock code groups, and it is known that it may also be an external configuration with at least one of the number of lock code groups and the transmission structure being different, or completely different, and it only needs to have a configuration that achieves the transmission and anti-theft functions as described above.

In summary, the technical means disclosed in this invention can effectively solve the problems of knowledge and achieve the expected purpose and effect. Moreover, it has not been seen in publications and has not been publicly used before the application, and it has long-term progress. It is indeed an invention as referred to in the Patent Law. Therefore, I have filed an application in accordance with the law and sincerely pray that the Supreme Court will give a detailed review and grant the invention patent. I will be very grateful.

However, the above are only several preferred embodiments of the present invention, and should not be used to limit the scope of implementation of the present invention. In other words, all equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the invention specification should still fall within the scope of the present invention patent.
