A detachable positioning connection structure is provided between the handle body 1 and the handle transmission component 4. The detachable positioning connection structure includes a positioning groove 8 formed on the handle transmission component 4 and a positioning protrusion 9 provided on the handle body 1. The positioning protrusion 9 extends into the positioning groove 8 and connects to the handle transmission component 4. Specifically, in this design, by providing a detachable positioning connection structure between the handle body 1 and the handle transmission component 4, the handle body 1 and the handle transmission component 4 can be easily connected or disassembled, improving the maintainability and ease of use of the product. Furthermore, the detachable positioning connection structure simplifies the handle assembly process and reduces production costs. Simultaneously, the detachable connection between the outer positioning housing 5 and the inner positioning housing 6 allows users to easily replace or repair the product as needed, further enhancing its practicality and durability.

[0020] Furthermore, an annular groove 10 is formed recessed on the end face of the handle body 1 near the handle transmission component 4. A first annular magnet 11 is disposed within the annular groove 10, and a positioning protrusion 9 is disposed on the first annular magnet 11. A second annular magnet 12 is disposed within the positioning groove 8 of the handle transmission component 4. The thickness of the second annular magnet 12 is less than the depth of the positioning groove 8. The positioning protrusion 9 of the first annular magnet 11 extends into the positioning groove 8 and is magnetically connected to the second annular magnet 12. Specifically, in this embodiment, a stable connection between the handle body 1 and the handle transmission component 4 is achieved by respectively providing a first annular magnet 11 and a second annular magnet 12 on the handle body 1 and the handle transmission component 4, and utilizing their magnetic connection. This magnetic connection method not only simplifies the connection structure and reduces the number of parts, but also effectively improves the stability and reliability of the connection. In addition, the provision of the first annular magnet 11 and the second annular magnet 12 also makes it easier and more convenient for users to disassemble and assemble the handle, further improving the usability of the product and the user experience.

[0021] Furthermore, the magnetic poles of the first annular magnet 11 and the second annular magnet 12 are opposite and attract each other.

[0022] Furthermore, a dual return structure is provided within the movable cavity 7. This dual return structure includes an elastic return unit 13 and a magnetic return unit 14. The elastic return unit 13 includes a return spring 15 fitted onto the portion of the handle transmission component 4 located within the movable cavity 7. The two ends of the return spring 15 abut against the handle transmission component 4 and the inner wall of the movable cavity 7, respectively, applying pressure to the handle transmission component 4. Specifically, in this embodiment, the dual return structure further enhances the stability and accuracy of the handle transmission component 4 during the return process. The elastic return unit 13 utilizes the elastic force of the return spring 15 to return the handle transmission component 4, ensuring that the handle automatically returns to its initial position when no external force is applied. This design not only improves the product's lifespan but also effectively avoids operational errors caused by inaccurate return of the handle transmission component 4. The magnetic return unit 14 utilizes the magnetic attraction between the first annular magnet 11 and the second annular magnet 12 to assist in the return of the handle transmission component 4, making the return process smoother and more stable. The dual return structure makes the handle's return more reliable, further improving product performance and user experience.

[0023] Furthermore, the magnetic return unit 14 includes a first return magnet 16 disposed on the inner wall of the movable cavity 7 and a second return magnet 17 disposed on the handle body 1. The first return magnet 16 and the second return magnet 17 are attracted to each other by opposite polarities. The second return magnet 17 is disposed on the portion of the handle body 1 located within the movable cavity 7 near the first return magnet 16. In this embodiment, the first return magnet 16 and the second return magnet 17 serve as the main components of the magnetic return unit 14. Through the magnetic attraction between them, they achieve auxiliary return of the handle transmission component 4. This design not only enhances the stability of the handle return but also makes the return process smoother and quieter, improving the user experience. At the same time, the first return magnet 16 and the second return magnet 17 adopt an opposite polarity attraction method, ensuring that the magnetic force between them is always kept in an optimal state, thereby guaranteeing the accuracy and reliability of the handle return. Furthermore, by placing the second return magnet 17 on the part of the handle body 1 located in the active cavity 7 near the first return magnet 16, the magnetic attraction between the two can be maximized, thereby improving the return efficiency.

[0024] Furthermore, a sealing element 18 is fitted onto one end of the handle transmission component 4 extending out of the movable cavity 7. The sealing element 18 has a sealing portion 19 and a connecting portion 20. The connecting portion 20 is fitted onto the handle positioning assembly 3, and the sealing portion 19 is fitted onto the handle transmission component 4 and is interference-fitted with it. Specifically, in this embodiment, the design of the sealing element 18 further enhances the sealing performance of the entire device. The sealing portion 19 fits tightly onto the handle transmission component 4 through an interference fit, effectively preventing external dust, moisture, and other impurities from entering the movable cavity 7, thereby protecting the stability and service life of the internal mechanical structure. At the same time, the connecting portion 20 is firmly fitted onto the handle positioning assembly 3, which not only enhances the connection strength between the sealing element 18 and the handle transmission component 4 but also ensures the consistency and reliability of the sealing effect.

[0025] Furthermore, the sealing element 18 has a tapered cross-sectional shape, the diameter of the sealing portion 19 is smaller than the diameter of the connecting portion 20, and the inner wall of the connecting portion 20 protrudes to form an annular connecting portion 21. An annular connecting groove 22 for connecting the annular connecting portion 21 is provided on the handle positioning assembly 3. Specifically, in this embodiment, the sealing element 18 adopts a tapered design, creating a natural transition between the sealing portion 19 and the connecting portion 20. This design not only optimizes the fit between the sealing element 18 and the handle transmission component 4 and the handle positioning assembly 3, but also enhances the sealing effect. The smaller diameter end of the sealing portion 19 fits tightly against the handle transmission component 4, achieving good sealing performance through an interference fit, effectively preventing the intrusion of external impurities. The larger diameter end of the connecting portion 20 matches the annular connecting groove 22 on the handle positioning assembly 3 through the annular connecting portion 21. This design not only increases the contact area between the sealing element 18 and the handle positioning assembly 3, improving the stability of the connection, but also further enhances the sealing effect.
