Detailed ways

In order to further understand the structure, features and purpose of the utility model, please refer to the following detailed description of the accompanying drawings and specific embodiments of the utility model:

Referring to Fig. 1, Fig. 2 and Fig. 3, the writing pen 1 of the present utility model, such as a gel pen or a cylindrical pen, includes a pen holder 10, a pen cap 20, a tip cover 30, a refill 40, a push assembly 50 and a pen clip. device 60. Wherein, the pen holder 10 is a cavity structure, one end of which is connected to the pen cap 20, and the other end is connected to the tip sleeve 30, and the connection method can be selected from other known methods such as screw connection or clamping. Viewed from the side, the connection between the pen holder 10 and the pen cap 20 is an S-shaped curved surface. The pen holder 10 and the point cover 30 can also be integrally formed, and at this time the pen holder 10 needs to be composed of two parts detachably connected. The pen cap 20 is provided with a pen clip 21, and the end of the pen clip 21 is provided with a protrusion 211, and the protrusion 211 is semicircular or in any shape.

The pressing assembly 50 includes a spring 51 , a rotating wheel 52 , a pressing core 53 and a pressing head 54 . One end of the pen core 40 passes through the spring 51, and passes through the tip cover 30, and its other end contacts with the runner 52 or is accommodated in the runner 52, and the top of the runner 52 is connected with a pressing core 53 and a pressing head 54 in turn. For example, the runner 52 is accommodated in the pressing core 53 , and the pressing core 53 is accommodated in the pressing head 54 . The rotating wheel 52 includes a transmission part 521 and a connecting part 522. At least two square protrusions 523 are provided on the circumference of the transmission part 521. In this embodiment, four protrusions are preferably provided. The protrusions 523 extend beyond a part of the connecting part 522. . The lower end of pressing core 53 is provided with some serrations 531, and the outer circumference of pressing core 53 is provided with groove 532, and this groove 532 is used for accommodating the protrusion 523 on the running wheel 52, and its number is the same as the number of protrusions on the running wheel 52. 523 corresponds. The upper end of the pressing core 53 is connected with the pressing head 54, and the pressing head 54 passes through the pen cap 20, and the pressing core 53 and the pressing head 54 can also be integrally formed. The inner wall of the pen holder 10 is provided with a guide rail (not shown), which cooperates with the pressing core 53 and the runner 52 to realize the pressing of the pen core 40 . When in use, press the pressing head 54 to drive the pressing core 53 and the runner 52 to slide down and rotate under the action of the guide rail, and the pen core 40 is pushed out of the tip cover 30; when not in use, press the pressing head 54 again, The pen core 40 returns to the original state under the action of the spring.

Referring again to FIG. 4 , FIG. 5 and FIG. 6 , the pen clip opening device 60 includes a push member 61 and a support member 62 . The supporting member 62 is fixed on the pen holder 10 , opposite to the pen holder 21 , and has an arc-shaped groove 621 . The push member 61 is provided with a rectangular hole 611 and a receiving groove 612 , the pen holder 21 passes through the hole 611 , and the end of the pen holder 21 is fixed in the receiving groove 612 through the protrusion 211 . At least one arc-shaped protrusion 613 is provided on the inner side of the push member 61 , preferably two arc-shaped protrusions are provided in this embodiment, and the top surface of the protrusion 613 is preferably semicircular. The protrusion 613 is supported in the arc-shaped groove 621 on the support member 62 and can slide in the groove 621 .

When the pen 1 is not in use, you only need to press the upper end of the pusher 61 with your hand, and the arc-shaped protrusion 613 slides in the arc-shaped groove 621, so that the lower end of the pusher 61 is tilted up, and drives 21 pen clips. At this time, it can be conveniently hung in a clothes pocket or other places, and then the arc-shaped protrusion 613 will slide in the groove 621 and return to the original state. In this way, it is possible to prevent the pen from falling easily due to the excessive distance between the pen clip 21 and the pen holder 10 .

For more comfortable use, the pen also includes a sheath 70 made of elastic material, such as rubber, which is sheathed on the lower half of the pen holder 10 . For example, a hole 71 may be provided on the sheath 70, and a bump 11 may be provided on the penholder 10, and the sheath 70 is sleeved on the bump 11 of the penholder 10 through the hole 71, thereby fixing the sheath 70 on the penholder 10 , of course, bonding or other known methods can also be selected.

The above-mentioned pen clip opening device can also adopt other methods, as long as one end of the pen clip opening device is pressed with the help of a support point, the other end is tilted upwards, thereby driving the pen clip to open. The supporting member in the above embodiments can be integrally formed with the pen holder.

Although the present utility model has disclosed the preferred embodiments as above, it is not intended to limit the present utility model. Any person skilled in the art can make various modifications and modifications without departing from the spirit and scope of the present utility model. , so the scope of protection of the utility model should be based on the scope of claims of the patent application.
