Nong Nongjiu [Related Technology] The starting point of the trimmer of the present invention, "', P is based on a clear explanation of the technology of the Xidian women's trimmer, which is disclosed in the raft attack and moonscape related to the Wu Guo patent case No. 5,950,3 No. 15. Because of the structure characteristics of Taiyiming trimmer, because of the nature of this book & it is not in the color of the above patent, which is used for reference in this application. ~ The trimming known from the above patent In the device, a cutting blade supported by an elastic lens can be rotated around a-pivot point, and it is formed with a fixed positioning relative blade-a jaw, which is used as a driving mechanism. It transmits power to the cutting blades by 'transmitting power to the cutting blade. In the driving mechanism', the chain is attached to a chain connected to a driving wheel, which is connected to a driving line. The driving line has a length of about Drive wheel. The sprocket and drive gear are configured to rotate around their common axis. When the drive wire is no longer pulled, the blade spring returns the drive wire to its original position. This drive mechanism is simple and reliable. The above drive mechanism does have a problem. In the trimmer described in US Patent No. 5,950,3 and 15, the trimmer head is installed in a rotating shaft relative to the trimmer's elongated shell, so that the angle of the trimmer can be adjusted relative to the elongated shell. The adjustment can make the drive wire wind the drive wheel or unload it. If the drive wire winds the drive wheel, it also winds the sprocket at the same time. Of course, the sprocket guides a pulling force on the moving blade through the chain to change the particle In order to make this item # more complete or offset 'elongation at one end of the drive line continued 86962 200412835 < the attachment must be removed' so more drive lines removed to make the jaw to return It has the largest size. Even if this adjustment of the drive line length can be implemented in an early manner relative to the knot of the drive line used to attach to the long case, the fact that the drive line is adjusted 'still causes There is some additional inconvenience. [Summary of the Invention] "The purpose of the present invention is to make the trimming described in the above-mentioned and U.S. patents as' advance in the following ways, that is, the drive mechanism automatically completes the drive line. length So that the position of the cutting head be adjusted relative to the elongate housing, without affecting the width of the jaw portion. This situation eliminates the need to adjust the length of the drive line to the size of the rhyme. The above-mentioned object is achieved by the trimmer according to the present invention. The trimmer includes a knife-knife blade having a 'around-pivot point' pivotably connected to a jaw and resiliently supporting it, The trimming head is matched with the blades to cut the work pieces contained in the bay part formed by the rhyme; a driving mechanism connected to the trimming head; an elongated casing connected to the driving mechanism; the driving mechanism includes: A first and a second connecting portion 'can be selectively rotated relative to each other about an axis' to allow the positioning of the trimming head relative to the elongated shell, the first connecting portion is connected to the elongated shell, And the second connection part is connected to the trimming head; a first wheel that can rotate around the axis; 86962 200412835. It can rotate around the axis and borrow a head line to connect the company's line ## at the-connection point Connected to the second round (the second round, when the head is turned, the green head is wound around the guide table of the second round:; :: This wheel rotates around the axis—the drive line device, which includes a drive to pull and maintain The second round is non-gravity, and: It is configured as the driving line of the settled Gotuda ^ male head for comparison When touched, the second wheel and the first wheel are rotated together. According to a preferred embodiment of the present invention, the through hole device in the second wheel includes: Yu Di * Allow the guide of the drive line to pass through the second round, privately; w 々% & 'for accommodating the guide line <the first part of the drive line, when the first fish turns > poor ,, " The first channel on the inner surface is used for accommodating the first part that leads through the first drive line and slides through this hole: the second channel in the second connection part is used to guide the side of the second connection part "drive line" When the trimming head is positioned relative to the elongated shell, the first transport rotates with the second connection portion, and the third channel on the-connection portion is used for the second drive of the drive line. One end of the second part of the wire is connected to the first connecting part, and the length of the second part of the driving wire is determined by the position of the trimming head relative to the elongated shell. It can be understood from the foregoing that the driving mechanism of the trimmer of the present invention has two operating states, one is an effective operating state when the trimmer is used in a normal manner, and the other is when the angle of the trimming head is adjusted relative to the long casing. Time effective operating state. The operating conditions of the two require that the length of the driving wire should be trimmed separately from each other, so that the driving mechanism can operate as expected, and allow the position of the male head to be adjusted relative to the long casing without causing production. 86962 [The entire length of the drive line is maintained for 15 weeks.] Shao needs the required size. The present invention is related to the invention of a trimmer, which is often referred to as a trimmer. The mechanism and operating application described in the present invention To other cutting tools. Cutting tools. However, when described in this case, those skilled in the art can understand that the principle, in general, is a tool or trimmer that can be broadly referenced to the figure knife and the male branch, which is generally indicated by the reference number 10. In other words, it includes a trimming head 12, a middle-length casing 14 (only a part of which is shown), and a driving mechanism 16 disposed between the trimming head 12 and the base 14. The trimming blade includes a blade 18 'that can be rotated around a pivot axis and is matched with the blade portion 20 to constitute the bay portion 22, and its configuration is configured to accommodate the work piece for the blade 18 to cut. A spring% pushes the blade 18 toward an open position relative to the jaw 20. Since the present invention is particularly related to the driving mechanism 16, the following description will focus on the operation of the driving mechanism, regardless of the structural members related to the trimming head and operation, or the extension of the housing and the handle, or the fixing of the driving wire to these handles. These components are completely identical in structure and operation with respect to the corresponding components disclosed in the aforementioned US Patent No. 5,95,315, No. 5,95,315. According to the present invention, the 'driving mechanism 16 includes a first and a second connecting portion 3 2 and 34' individually, and can rotate relative to each other about an axis 36. The first connection part 32 is connected to the elongated shell 14, and the second connection part 34 is connected to the trimming head 12. A bolt constitutes the shaft center 36, which is used to abut the connecting portions 32 and 34 against each other. The surface of the portion 32 to be disposed on the portion 34 is provided with a saw tooth 40, and this surface is disposed in the flange 38 in the insertion portion 34. 86962 200412835 The inside of the flange 38, that is, the inner edge of the connecting portion 34, is provided with anti-aliasing 42 corresponding to the sawtooth 40. When the connecting portions 32 and 34 are arranged opposite to each other, the serrations on the opposite surfaces are placed opposite each other, and the connecting portions are locked in a desired position relative to each other. Only by releasing the force pressing the connecting portions 32 and 34 toward each other, can the portion 3 4 be allowed to rotate relative to the portion 32. As mentioned above, the connecting portion 32 is connected to the elongated casing 14, which can bring the trimming head of the trimmer of the present invention to a desired height to cut off the branches located at a particularly high degree. Therefore, the connection portion 34 is rotated relative to the portion 32 to indicate that the angle of the trimming head is adjusted relative to the elongated casing 14. This angle < trimming is usually better so that the branches are cut off at a desired angle. In fact, as mentioned above, the connecting portions 32 and 34 are loosened relative to each other by rotation, and are configured around the axis 36, and are locked under the locking nut 46 at the end of the axis to tighten. The shape of the nut 44 is generated. The wing nut material is not placed on the outer surface of the connection Shao 32 as shown in Figure 2. Below the wing nut 44 is a reverse surface that rises in the form of a disk for the wing nut 44. < Used to facilitate the rotation of the wing nut material between the two rotation positions between: βIM knife 32 and 34 to complete a tightening and a loosening position. In the air-open position, the connecting Shao Fen 32 and 34 series can be tightened relative to each other. ^ In the release position, the axial screw inspection 36 borrows a spring blade 48 placed between the axial screw inspection member # 82 and the outer surface of the connecting portion 34, and the joints 32 and 34 There is an appropriate degree of tightness. The driving mechanism 16 for driving the blade 18 for the king king member includes two driving wheels 50 and a sprocket 52. The sprocket 52 is connected to the blade 18 by a head wire 54 (eg, by means of the cymbals 56 and 58). As shown in the drawings, the head line 86962 200412835 5 4 is preferably a chain. Those skilled in the art can still understand that a rope, an electric wire or a belt can also be used as the head line 54. One of the head lines 54 is connected to the sprocket 52 at a connection point. The other end of the head line is connected to an area 60 of the arm portion 62 of the blade 18 extending from the pivot point 19. The sprocket 52 includes a slot, which is used to receive the chain 54 when the sprocket 52 rotates around the axis 36 while the trimmer is cutting. As can be seen in FIG. 2, the sprocket 52 is placed in the connecting portion 34. Because in the driving mechanism of the present invention, when the rotation position of the connection portion "is adjusted relative to the connection portion 32, the blade 18 comes in compliance with a pulling force, so the sprocket 52 performs this adjustment. At the same time, the system rotates with the connecting part 34. The driving mechanism further includes a second wheel, namely the driving wheel 50. This wheel is also located on the shaft ^ 36, and once the driving mechanism is assembled, the driving wheel 50 Placed in the joint ~ α (5 wound 32). Contrary to the driving wheel 52, this wheel is not adjusted around the axis 3 when the position of the trimming head 2 is adjusted relative to the elongated housing 14 of the trimmer of the present invention. 6 rotation. The above-mentioned function, that is, the operation of trimming head on the one hand and the angle adjustment of the trimming head = the extended shell of the trimmer on the other hand, is mainly based on the driving line that drives the trimming head, which is arranged in the driving mechanism. In Figure 2, the driving line and its positioning in the driving mechanism are exemplified by a dashed line and related arrows. The latter two show that the elongated shell from the trimmer passes the driving mechanism to its attachment point. Stroke direction. Drive line via the first connection The hollow shaft 64 of the knot part enters the driving mechanism. At this point, the driving line is indicated by the reference number 66. Secondly, the driving line is guided around the driving wheel 50 and is used as the trimming head 丨 2 At its normal position of 86962 -11 · 200412835, that is, when it is approximately parallel to the elongated housing of the trimmer, the drive wire is slightly wound around the drive wheel. The drive wire in this section is marked with reference numeral 68 < After winding around the drive wheel 50 a little more, the drive wire is guided through the sprocket 52. This through hole is marked with the reference number 70 and is located near the outer edge of the sprocket. The drive wire can drive itself The rim of the wheel 50 moves generally through the through-hole 70 in the direction of the axis%, so the edge of the through-hole entrance will not cause friction to the drive line. In order to make the drive line as smooth as possible and with a smaller It moves frictionally through the through-hole 70, and the sprocket 52 is formed with a substantially rectangular opening, which is equipped with a pivot portion 72. The rotation axis of this wheel is perpendicular to the axis of the sprocket 52, that is, Perpendicular to the direction of bolt 36. wheel 72 A U-shaped groove is provided, and the bending radius of the U-shaped groove generally corresponds to the bending radius of the 0-shaped drive line; as a result, half of the drive line falls into a groove formed on the rim of the wheel portion 72. This ensures the drive The wire actually pulls off relative to the wheel portion 72, and the movement of the driving wire through the sprocket 52 is based on the rotation of the wheel portion 72. This means that the friction of the driving wire with respect to the through hole 70 is very low After the stroke has passed through the sprocket 52, the driving wire bypasses the shallow groove-shaped space made at the bottom of the second connection Shao Fang 34 in less than one turn. The driving wire of this section is marked with reference number 74. After making less than one turn around the bottom of the connecting portion 34, the 'drive wire is exposed on the outer surface of the connecting portion 34 through the bottom surface, that is, in the direction of the head 82 of the bolt 36 in FIG. 2 On the outer surface. The rear surface is formed with a relatively short groove for the drive line; this system is shown in FIG. The drive wire is introduced into a tubular through hole 78 through this groove, which protects the drive wire from external damage caused by the exposure of the drive wire at this point, provided that 86962-12-200412835 is more openly placed on the drive On the surface of the institution. The official through hole 78 guides the driving wire from the connecting portion 34 to the connecting portion 32 in the direction of the axis 36. Here, it introduces a groove-shaped space 80 formed along the outer surface of the connecting portion in a circular shape. The length of the groove in this section is about 3/4 of a circle. The drive wire passes through the groove 80. After a special distance, it is made from the groove 80 through a side formed there, to the surface of the connecting portion 32 where the wing nut material and the lock nut 46 are placed. The movement of the driving wire passes through the through hole After 84, it was made with a knot to prevent the movement of the drive line from passing through the opening μ. This situation provides an attachment point for the end of the drive line in the connecting portion 32. The operation of the drive mechanism of the trimmer of the present invention, and especially The operation of the drive line in different operating conditions will be described below. When the trimmer of the present invention uses Risi in a normal manner, a section 66 of the drive line is pulled, and as a result, a section 68 of the drive line will rotate the drive wheel. The force of 50 leads to it. This force is where the driving wheel 50 and the sprocket 52 are turned. In this case, of course, through the chain M million; the moving blade 18 guides a driving force, and the spring force is 1% of the pull force 1 Compete. When driving in this operating situation When the axis rotates, it pulls the driving wheel from the sprocket 52, and unloads the driving line through the hollow shaft of the connecting portion 32. This section of the driving line is from the bottom of the connecting portion M < A section of the driving line 74 is obtained. During the cutting action of the trimmer, the connecting portion 34 remains unchanged, and the sprocket 52 is rotated therein. A section of the driving line μ therefore passes through the through-hole 70 and is gradually unloaded to the The driving wheel 50 is further removed therefrom through the hollow shaft 64 of the connecting portion 32. In this normal operation, the driving wheel 50 and the sprocket 52 rotate together. In the case, The drive line 74, 86962 -13- 200412835, which is located at the bottom of Shao Fen 34, therefore needs additional compensation for the drive line caused by the drive line not directly attached to the sprocket 52, but the drive line is continuous through the sprocket. To achieve an operation required according to the present invention, so that the angle of the trimmer is adjusted without causing the need to adjust the length of the drive line. As already understood above, the angle of the trimming head is borrowed and will be connected to the trimmer 8 < Link Shao Fen 34, made The connecting portion 32 I connected to the extension housing 14 is rotated to make a longitudinal adjustment relative to the trimmer extension housing. According to the present invention, this rotation or rotation should not cause a pull of a section 66 of the driving wire, which This means that when adjusting, the position of the blade 18 relative to the relative blade 20 remains unchanged. This situation requires a special configuration; this configuration is shown in Figure 2. When the connection portion 34 is rotated, in order to prevent A pulling force is guided to the blade 18, and when adjusting, the sprocket 52 must rotate with the connecting portion 34. On the other hand, the position of the driving wheel 50 must be fixed to ensure that the driving line-segment & It is not pulled. In fact, when the angle is adjusted later, the driving wheel 50 remains stationary, and the sprocket 52 is rotated relative to the driving wheel 50. Depending on the rotation direction of the trimming head, that is, the connecting portion 34 is rotated relative to the connecting portion M. Either there are more driving wires wound around the driving wheel 50 or the driving wires are unloaded there. If the connecting portion 34 is rotated in the direction of the driving wheel in accordance with one of the driving wires, more driving wires will be wound around the driving wheel 50. Since the sprocket 52 rotates together with the connecting portion 34, a section μ without a driving wire is dismounted, and the angle is adjusted. Therefore, the additional driving line is obtained from a section 82 of the driving line placed in the groove portion 80 connected to the two parts 32. As can be seen in FIG. 2, the connecting portion is rotated in the direction mentioned above, which means that the through hole 78 therein is rotated relative to the connecting portion 32. It is located in the slot 86962 -14- 200412835 and is driven in 80 A section 82 of the line is partially allowed to be detached from the groove portion 80, and passes through the straight through-hole tube 78, and then enters the groove portion on the bottom of the connecting portion 34, and passes through the through-hole 70 in the sprocket 52, and Up to the driving wheel 50. Similarly, when the repair head is rotated in the direction opposite to the above and above, that is, the direction opposite to the direction of the driving line on the driving wheel 50, the driving on the driving wheel 50 The thread will be unloaded 'to allow it to move in the opposite direction to the direction previously mentioned, through the slot on the bottom of the connection Shao 34, through the through hole 70, and through the through hole 7 8 into the connection Shao 3 2 Slot section on the outer edge § 〇. In different operating conditions, a section of the drive line located on the drive wheel 50 and a section of the drive line located in the slot section are complementary in length in this way. Adjust the angle of the elongated shell of the trimmer without causing adjustment The length of the moving line is required, and therefore the width of the jaw will not be changed when this adjustment is made. Of course, the above operation requires that the diameter of the driving wheel 50 should be appropriately made relative to each other, that is, actual; Diameters should be generally equal in size. It is understood that the above is a description of the preferred exemplary embodiment of the present invention, and that the present invention is not limited to the above-mentioned explicit form. For example, when the present invention is in the form of a -trim When related devices appear, they can be used together with other devices. The driving wheels and sprockets can have other configurations, while retaining their basic functions. However, I should understand that these fish farmers Other substitutes, modifications, changes, and omissions can be made in the disclosure of the cleverness and configuration of the components in this application, without departing from the attached, please patent the patent garden.
