The locking member 2 has a guide post 21 and a locking post 22 that extends into the limiting cavity 11 through the clearance opening 12. The pressing block 3 is rotatably connected to the main body 1. The pressing block 3 is provided with a guide groove 31 that cooperates with the guide post 21. The resetting member connects the pressing block 3 and the locking member 2 to prevent the locking post 22 from exiting the limiting cavity 11.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: The sliding sleeve has a simple and novel structure, which can realize press unlocking, and is more in line with the usage habits of some users. When the user needs to change the height of the sliding sleeve, he only needs to press the pressing block 3, which will then overcome the elastic force of the reset member and rotate, driving the locking member 2 fixed to it to slide synchronously, so that the locking pin 22 exits the lock hole on the device body in the limiting cavity 11, and releases the limitation between the main body 1 and the device body. At this time, the user can drive the main body 1 to slide along the device body to the required height. After reaching the target position, the user can release the pressing block 3, and the reset member will immediately drive the pressing block 3 to rotate. The locking pin 22 will pass through the clearance opening 12 again and extend into the corresponding lock hole to complete the locking. The whole operation process is very simple.

[0021] Please refer to Figure 1 and Figure 2 Furthermore, the pressing block 3 includes a vertical plate 32, which is rotatably connected to the main body 1 via a rotating shaft 6, and the guide groove 31 is provided on the vertical plate 32.

[0022] Furthermore, the pressing block 3 also includes a pressing plate 33 protruding in a direction away from the limiting cavity 11, and the pressing plate 33 is connected to the upright plate 32.

[0023] As can be seen from the above description, the pressing plate 33 can provide a large contact area, thus making it convenient for the user to press the pressing block 3.

[0024] Please refer to Figure 1 and Figure 4 Furthermore, the reset component is a torsion spring sleeved on the rotating shaft 6, and the main body 1 is provided with a receiving groove 13 for accommodating the torsion spring.

[0025] As can be seen from the above description, the manufacturing cost of the sliding sleeve can be controlled by using standard torsion spring parts; the torsion spring is housed in the receiving groove 13, which facilitates the control of the assembly gap between the pressing block 3 and the main body 1.

[0026] Please refer to Figure 1 , Figure 3 and Figure 4 Furthermore, the main body 1 is provided with a positioning plate 5, which is located below the pressing block 3.

[0027] As described above, when pressing the pressing block 3, the user can use the positioning plate 5 for leverage. Specifically, the user can place the web of their hand towards the gap between the pressing block 3 and the positioning plate 5, with their thumb and other fingers touching the pressing block 3 and the positioning plate 5 respectively, and then close their web to drive the pressing block 3 to rotate. This operation can effectively prevent the user from slipping when operating the pressing block 3, thus improving the safety of the user's operation.

[0028] Please refer to Figure 4 Furthermore, the main body 1 is provided with a sliding groove 151, and the locking member 2 has a slider that is adapted to the sliding groove 151.

[0029] As can be seen from the above description, the cooperation between the slide groove 151 and the slider can improve the smoothness of the sliding of the locking member 2 and restrict the locking member 2 to slide in only one direction, thereby ensuring the stability of the sliding sleeve.

[0030] Please refer to Figure 4 Furthermore, the main body 1 includes a body 14 and a mounting block 15 mounted on the body 14. The limiting cavity 11 and the clearance opening 12 are respectively provided on the body 14, and the sliding groove 151 is provided on the mounting block 15.

[0031] As can be seen from the above description, placing the slide groove 151 on the mounting block 15 facilitates the processing and forming of the slide groove 151.

[0032] Please refer to Figure 3 Furthermore, the locking member 2 is L-shaped, the locking post 22 is located near one end of the locking member 2, and the guide post 21 is located near the other end of the locking member 2.

[0033] As can be seen from the above description, the L-shaped locking component 2 has a simple structure and is easy to process and manufacture.

[0034] Please refer to Figure 4 Furthermore, the outer surface of the main body 1 is provided with a receiving groove 16, and at least a portion of the locking member 2 is received in the receiving groove 16.

[0035] As described above, the receiving groove 16 can protect the locking element 2 to a certain extent, reduce the risk of the user being accidentally scratched by the locking element 2, and allow the length of the locking pin 22 to be set shorter, so that the locking pin 22 can bear a greater shearing force, further reducing the risk of the sliding sleeve accidentally sliding along the device body.

[0036] Please refer to Figure 1 and Figure 2 Furthermore, the main body 1 is provided with an installation structure 4 for installing accessories.

[0037] As described above, the relative position of the accessory and the device body can be adjusted by using the sliding sleeve, making it easier for users to use the accessory.
