[0036] The adjusting rod 8 can move back and forth. The front end of the adjusting rod 8 is fixedly connected to the needle plate 3. External threads are provided on the outer side wall of the rear end of the adjusting rod 8. It can move back and forth inside the connection hole 7, and the front end is fixedly connected to the needle plate 3. The adjusting rod 8 is the key component to realize the adjustment of the extension length of the skin-breaking needle 1.

[0037] A rotatable rotating head 9 is connected to the rear end of the handle 6. The rotating head 9 is threadedly connected to the rear end of the adjusting rod 8. When the rotating head 9 rotates, through the threaded connection with the adjusting rod 8, the adjusting rod 8 can move back and forth. By rotating the rotating head 9 to push the adjusting rod 8 back and forth, the extension length of the skin-breaking needle 1 is adjusted.

[0038] The fine movement of the adjusting rod 8 is achieved by the rotation of the rotating head 9, so that the length of the skin-breaking needle 1 extending out can be precisely controlled to meet different treatment requirements and skin conditions. The user only needs to rotate the rotating head 9 to complete the adjustment, and the operation is simple and intuitive. The threaded connection has a certain self-locking property, which can keep the position of the adjusting rod 8 stable after the adjustment is completed, ensuring the fixed length of the skin-breaking needle 1 extending out. When treating different parts or different skin sensitivities, the length of the skin-breaking needle 1 extending out can be flexibly adjusted by rotating the rotating head 9 to achieve the best treatment effect and avoid excessive damage to the skin.

[0039] It also includes an annular rotating sleeve 10. The rotating head 9 is threadedly connected to the adjusting rod 8 by means of the rotating sleeve 10. The rotating sleeve 10 is threadedly connected to the rear end of the adjusting rod 8. The inner side wall of the rotating sleeve 10 is provided with internal threads, and the rotating sleeve 10 is fixedly connected to the rotating head 9 in the circumferential direction.

There are multiple limiting parts 11, and the multiple limiting parts 11 are arranged at intervals in the circumferential direction of the handle 6. The adjusting rod 8 passes through the multiple limiting parts 11, and the front end of the rotating sleeve 10 abuts against the limiting parts 11, providing front-side support and limit for the rotating sleeve 10 to prevent it from moving forward excessively. The rear end of the rotating sleeve 10 abuts against the inner wall of the rotating head 9.

[0041] On the side wall of the rear end of the rotating sleeve 10, there are positioning grooves 12. The positioning grooves 12 run through both sides in the radial direction of the rotating sleeve 10. There are multiple positioning grooves 12, and the multiple positioning grooves 12 are arranged at intervals in the circumferential direction of the rotating sleeve 10. On the inner side wall of the rotating head 9, there are protruding positioning pieces 13. The positioning pieces 13 are inserted into the positioning grooves 12 to fixedly connect the rotating sleeve 10 and the rotating head 9 in the circumferential direction. The multiple positioning grooves 12 on the rear end side wall of the rotating sleeve 10 cooperate with the protruding positioning pieces 13 on the inner side wall of the rotating head 9, making the rotating sleeve 10 and the rotating head 9 fixedly connected in the circumferential direction. This ensures that the rotation of the rotating head 9 can effectively drive the rotation of the rotating sleeve 10, thereby pushing the adjusting rod 8 to move back and forth to achieve precise adjustment of the length of the skin-breaking needle 1 extending out.

[0042] Through structures such as the limiting parts 11, the positioning grooves 12 and the positioning pieces 13, the stability and reliability of the entire adjustment mechanism during operation are improved.
