[0019] Please refer to Figures 1 to 4 The sliding sleeve includes a main body 1, a locking member 2, a pressing block 3, and a resetting member 4. The main body 1 has a limiting cavity 11, and the cavity wall of the limiting cavity 11 is provided with a clearance opening 12. The locking member 2 is slidably disposed on the main body 1. The locking member 2 has a guide groove 21 and a locking pin 22 that extends into the limiting cavity 11 through the clearance opening 12. The pressing block 3 is slidably disposed on the main body 1. The pressing block 3 is provided with a guide pin 31 that cooperates with the guide groove 21. The resetting member 4 connects the main body 1 and the locking member 2 to drive the locking pin 22 into 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 to drive the locking part 2 to overcome the elasticity of the reset part 4 and slide, 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 releases the pressing block 3, and the reset part 4 immediately drives the locking part 2 to reset. The locking pin 22 passes through the avoidance opening 12 again and extends into the corresponding lock hole to complete the locking. The whole operation process is very simple.

[0021] Please refer to Figure 1 Furthermore, the locking member 2 is slidable along the first direction, and the pressing block 3 is slidable along the second direction, with the first direction being perpendicular to the second direction.

[0022] As can be seen from the above description, the pressing direction of the pressing block 3 is perpendicular to the sliding direction of the locking member 2, which is more in line with the user's usage habits.

[0023] Please refer to Figure 1 Furthermore, there are two pressing blocks 3, which are arranged opposite to each other. The locking member 2 is provided with two guide grooves 21, which correspond one-to-one with the two pressing blocks 3.

[0024] As described above, the two opposing pressing blocks 3 ensure balanced force on the locking element 2 during unlocking, thus guaranteeing smooth sliding of the locking element 2. In practice, the user can position their palm with the web of their hand facing the gap between the two pressing blocks 3, with their thumb and other fingers touching each pressing block 3 respectively. Then, they can close their palm to drive the two pressing blocks 3 to slide towards each other. This operation effectively prevents slippage when operating the pressing blocks 3, improving user safety. Furthermore, after unlocking, the user can squeeze the two pressing blocks 3 with one hand and use the movable mounting block 14 to slide the main body 1 along the device body, further facilitating user operation.

[0025] Please refer to Figure 1 and Figure 4 Furthermore, it also includes an elastic element 6, which connects the two pressing blocks 3.

[0026] As can be seen from the above description, the elastic element 6 can drive the two pressing blocks 3 to slide in a direction away from each other, so that the locking element 2 can be reset more quickly. At the same time, it disperses the force on the reset element 4, which helps to extend the service life of the reset element 4.

[0027] Please refer to Figure 1 Furthermore, the main body 1 is provided with a first sliding groove 141, and the pressing block 3 has a first slider 32 adapted to the first sliding groove 141.

[0028] As can be seen from the above description, the cooperation between the first groove 141 and the first slider 32 can improve the smoothness of the sliding of the pressing block 3 and restrict the pressing block 3 to slide only in the second direction, thereby ensuring the stability of the sliding sleeve operation.

[0029] Please refer to Figure 1 Furthermore, the main body 1 includes a body 13 and a mounting block 14 mounted on the body 13. The limiting cavity 11 and the clearance opening 12 are respectively provided on the body 13. There are two mounting blocks 14, and the two mounting blocks 14 correspond one-to-one with the two pressing blocks 3. The first sliding groove 141 is provided on the mounting block 14.

[0030] As can be seen from the above description, placing the first groove 141 on the mounting block 14 facilitates the processing and forming of the first groove 141.

[0031] Please refer to Figure 1 , Figure 4 and Figure 5 Furthermore, a second groove 15 is formed between the two mounting blocks 14 and the body 13 at their adjacent ends, and the locking member 2 has a second slider 23 adapted to the second groove 15.

[0032] As described above, the cooperation between the second slide groove 15 and the second slider 23 can improve the smoothness of the sliding of the locking member 2 and restrict the locking member 2 to slide only in the first direction, thereby ensuring the stability of the sliding sleeve. Moreover, the second slide groove 15 is formed by assembling the mounting block 14 and the body 13, which is a very simple forming method and helps to control the manufacturing cost of the sliding sleeve.

[0033] Please refer to Figure 1 and Figure 3 Furthermore, the locking member 2 is L-shaped, the locking pin 22 is located near one end of the locking member 2, and the guide groove 21 is located near the other end of the locking member 2.

[0034] 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.

[0035] Please refer to Figure 1 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.

[0036] 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.
