A positioning portion 23 is provided on the right side of the first end of the pen body 2 along the up and down directions, and a first positioning groove 231 and a second positioning groove 232 are respectively provided on the front and rear sides of the positioning portion 23. A first magnet 233 is provided in the positioning portion 23, and the first magnet 233 extends rightward from the positioning portion 23. The positioning portion 23 is specifically connected to the pen body 2 and is arranged up and down. The positioning portion 23 is specifically located between the first guide groove 21 and the second guide groove 22. The general structure of the pen body 2 is basically similar to that of the pen body in the prior art, and both include components such as a PCB board and a battery.

[0033] The pen head of the present invention is electrically connected to the pen body 2. The pen head includes a pen head 3, a connecting part 4 and a connecting member. The connecting member includes a first guide rod 51 located at the front side and a second guide rod 52 located at the rear side. A first connecting rod 53 is provided on the left side between the first guide rod 51 and the second guide rod 52. A second connecting rod 54 is provided on the right side between the first guide rod 51 and the second guide rod 52. The right middle part of the first guide rod 51, the right middle part of the second guide rod 52 and the second connecting rod 54 are all located in the connecting part 4 and the connecting part 4 A charging port 41 is provided, and the charging port 41 passes through the connecting portion 4. The charging port 41 and the pen tip 3 are both electrically connected to the pen body 2. The charging port 41 is a TYPE-C interface or other interface. The connecting portion 4 is connected to the pen tip 3. The second connecting rod 54 is located on the right side of the charging port 41.

The second connecting rod 54 is located on the right side of the charging port 41. The guide rod 52 is provided with a second protrusion 521 and a fourth protrusion 522 at intervals on the left and right sides of the front side. The first protrusion 511 and the second protrusion 521 are arranged in a front-to-back correspondence. The third protrusion 512 and the fourth protrusion 522 are arranged in a front-to-back correspondence. The first protrusion 511 and the third protrusion 512 are both adapted to the first positioning groove 231. The second protrusion 521 and the fourth protrusion 522 are both adapted to the second positioning groove 232. A second magnet 42 is provided in the connecting portion 4.

The first guide rod 51 and the second guide rod 52 slide left and right along the first guide groove 21 and the second guide groove 22 respectively to drive the second magnet 42 to move closer to or away from the first magnet 233 and to prevent the charging port 41 from being blocked or exposed by the pen barrel 1;

[0034] The connecting portion 4 of the present invention is partially located on the outside, and partially extends into the pen tube 1. When the pen tip 3 of the present invention is extended, the portion of the connecting portion 4 extending into the pen tube 1 is pushed out of the pen tube 1, and the portion of the connecting portion 4 originally located on the outside is away from the pen tube 1. When the pen tip 3 is retracted, the portion of the connecting portion 4 extending into the pen tube 1 is blocked and hidden by the pen tube 1, and the portion of the connecting portion 4 originally located on the outside is close to the pen tube 1. At this time, the outermost side of the connecting portion 4 is connected and unified with the pen tube 1 (can be regarded as a whole with the same height). Specifically, when the first guide rod 51 and the second guide rod 52 move to the farthest end along the first guide groove 21 and the second guide groove 22 respectively, the charging port 41 is exposed, the connecting portion 4 is separated from the pen tube 1, the first protrusion 511 is clamped in the first positioning groove 231, the second protrusion 521 is clamped in the second positioning groove 232, the spring 55 is compressed, and the second magnet 42 is close to the first magnet 233.

[0035] When the first guide rod 51 and the second guide rod 52 move to the farthest end along the first guide groove 21 and the second guide groove 22 respectively, the charging port 41 is blocked by the pen tube 1, the connecting portion 4 is fitted with the pen tube 1, the third protrusion 512 is clamped in the first positioning groove 231, the fourth protrusion 522 is clamped in the second positioning groove 232, the spring 55 is reset, and the second magnet 42 is away from the first magnet 233. In the present utility model, the first magnet 233 is fixed, and the second magnet 42 is also fixed on the connecting portion 4. When in use, if the spring 55 is compressed, the suction force between the first magnet 233 and the second magnet 42 can assist in clamping the third protrusion 512 and the fourth protrusion 522 respectively in the first In the positioning groove 231 and the second positioning groove 232, similarly, when the spring 55 is reset, the third protrusion 512 and the fourth protrusion 522 are separated from the first positioning groove 231 and the second positioning groove 232 respectively by the applied force until the first protrusion 511 and the second protrusion 521 are respectively engaged with the first positioning groove 231 and the second positioning groove 232. At this time, the first magnet 233 and the second magnet 42 are far away and will not attract each other. In the present utility model, the first positioning groove 231 and the second positioning groove 232 are a U-shaped groove body, and the structures of the first protrusion 511, the second protrusion 521, the third protrusion 512 and the fourth protrusion 522 are all adapted to the U-shaped groove body.

[0036] The present invention also includes a pen tail, which is arranged on the side of the pen tube 1 away from the pen tip 3. A button 6 and a three-color light 7 are provided in the pen tail. The three-color light 7 is electrically connected to the pen body 2, and the button 6 is in contact with the pen body 2. In the present invention, the user of the present invention can release the pressure by extending or retracting the pen tip 3 or pressing the button 6. At the same time, extending or retracting the pen tip 3 or pressing the button 6 does not affect the original function of the capacitive pen of the present invention. The three-color light 7 of the present invention is used for specific lighting, etc. The three-color light 7 is located between the button 6 in the pen tail and the pen tail at the end of the pen.

[0037] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of protection of the technical solution of the utility model.
