One end of the compression spring 6 away from the groove 5 is connected to the buckle 4.

[0033] Specifically, the buckle 4 is of an arc-shaped structure. The design of the arc-shaped structure can increase the contact area between the buckle 4 and the surface of the fixing frame, improving the locking effect on the fixing ring 2. A buffer pad is arranged on the inner wall of the buckle 4, and the buffer pad is made of rubber. The setting of the buffer pad can play a good buffering effect during locking, reducing the wear generated between the buckle 4 and the fixing frame. A plurality of anti-slip grooves 9 are arranged on the surface of the buffer pad at equal distances, and the cross-section of the anti-slip groove 9 is of a semi-circular structure. The setting of the anti-slip grooves 9 can increase the friction between the buffer pad and the fixing frame, improving the firmness of locking.

[0034] Furthermore, a limiting strip 8 is arranged on the outer wall of the buckle 4 close to the fixing ring 2, and a limiting hole 7 is formed on the outer wall of the fixing ring 2 close to the buckle 4. The limiting strip 8 can rotate into the limiting hole 7, and the limiting strip 8 and the limiting hole 7 are in interference fit. When the buckle 4 contacts the fixing frame, the limiting strip 8 can enter the limiting hole 7, thereby positioning the buckle 4 and avoiding the situation where the buckle 4 automatically flips. The limiting strip 8 is made of rubber. The rubber limiting strip 8 has good elasticity, facilitating the limiting strip 8 to be deformed by extrusion and enter the limiting hole 7.

[0035] It is worth mentioning that a pull ring 3 is arranged on the outer wall of the buckle 4, and the pull ring 3 is arranged at one end away from the rotating hinge 10.
