[0027] refer to Figures 1 to 5 According to a preferred embodiment of the pen tip 50 fixing structure of the present utility model, it should be noted that the structure of the pen tip 50 fixing structure is as follows: Figure 1 As shown, it mates with the external pen casing assembly. Specifically, as... Figure 1As shown, the external pen casing assembly includes a pen holder 10, a cover 20, and a connecting sleeve 30, with the product mounted on the connecting sleeve 30. The pen holder 10 has a cavity, both ends of which communicate with the outside. The cover 20 is located at one end of the pen holder 10 to close one end of the cavity, and the connecting sleeve 30 is located at the other end of the pen holder 10. Specifically, the connecting sleeve 30 has a through hole that extends through the connecting sleeve 30, and when the connecting sleeve 30 is mounted on the pen holder 10, the through hole communicates with the cavity. Additionally, the pen casing assembly also includes a pen cap (not shown in the figure), which is fitted onto the end of the connecting sleeve 30 facing away from the pen holder 10, with the end of the pen cap abutting against the pen holder 10.

[0028] It should be noted that this application is designed to cooperate with the end of the connecting sleeve 30 that is away from the pen holder 10. Specifically, the pen tip 50 fixing structure includes a fixing head 40 and a pen tip 50. The fixing head 40 cooperates with the connecting sleeve 30, and the pen tip 50 cooperates with the fixing head 40.

[0029] Specifically, the structure of the fixing head 40 is as follows: Figure 2 As shown, it has an insertion part 41, a stop part 42, and a mounting part 43. The two ends of the stop part 42 are connected to the insertion part 41 and the mounting part 43, respectively. The insertion part 41 is inserted into the communicating hole, while the stop part 42 contacts the end of the connecting sleeve 30 away from the pen holder 10. The pen tip 50 cooperates with the mounting part 43. It should be noted that the mounting part 43 is configured to limit the position of the pen tip 50. Furthermore, the insertion part 41, the stop part 42, and the mounting part 43 are integrally formed, and the forming method can be injection molding.

[0030] Furthermore, the mounting portion 43 has a first extension portion 431, a second extension portion 432, and a connecting portion 433. The first extension portion 431 and the second extension portion 432 are disposed opposite to each other and spaced apart by a predetermined distance. One end of each of the first extension portion 431 and the second extension portion 432 is connected to the connecting portion 433, and the other end of the connecting portion 433 is connected to the abutment portion 42. It should be noted that the maximum cross-sectional dimensions of the first extension portion 431 and the second extension portion 432 are the same as the cross-sectional dimensions of the abutment portion 42.

[0031] Furthermore, the connecting part 433 has an insertion groove 401 on the side opposite to the abutment part 42, and the insertion part 41 has a connecting hole 402 on the side opposite to the abutment part 42. The connecting hole 402 communicates with the insertion groove 401, and the width of the insertion groove 401 is greater than the diameter of the connecting hole 402. Specifically, the cross-sectional structure of the fixing head 40 is as follows: Figure 5 As shown. It should be noted that the sides of the first extension 431 and the second extension 432 that are close to each other are both curved surfaces, and the wall surface that forms the insertion groove 401 and faces the first extension 431 or the second extension 432 is also curved. Specifically, the curved surface of the first extension 431 and the corresponding curved surface of the insertion groove 401 are on the same plane, and the curved surface of the second extension 432 and the corresponding curved surface of the insertion groove 401 are on the same plane.

[0032] like Figure 4 As shown, the bottom wall forming the insertion slot 401 consists of two opposing arc-shaped walls to define the position of the pen tip 50. Furthermore, the length of the first extension 431 is shorter than the length of the second extension 432.

[0033] Furthermore, one end of the pen tip 50 is beveled and the other end is flat. The flat end of the pen tip 50 is inserted into the insertion groove 401 until it contacts the bottom of the insertion groove 401. At the same time, both sides of the pen tip 50 contact the sides of the first extension 431 and the second extension 432 that are close to each other.

[0034] It should be noted that the pen tip 50 has a rectangular cross-sectional shape. The difference between this utility model and the existing pen tip 50 structure is that the existing pen tip structure has only a single pen tip, while the advantage of this application is that it reduces the space occupied by the pen tip 50. Moreover, due to its simpler shape, it is easier to manufacture and has a lower cost than the existing pen tip 50 structure. In addition, the addition of the fixing head 40 can limit the position of the pen tip 50. At the same time, the first extension 431 and the second extension 432 located on both sides can prevent the pen tip 50 from colliding directly with other hard objects during use, which would cause the pen tip 50 to fall off.

[0035] In summary, the pen tip fixing structure described in the embodiments of this application is explained, which provides advantages such as reliable connection, resistance to detachment, and novel structure.

[0036] It is worth mentioning that, in this embodiment, the pen tip fixing structure is simple in structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the pen tip fixing structure provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0037] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
