[0036] Furthermore, two circumferentially distributed third guide holes 23 are provided on the liner 2, and two second guide pillars 14 are provided on the buckle 1, and each second guide pillar 14 passes through a corresponding third guide hole 23. The first guide pillar 12 and the second guide pillar 14 are located on the same circumference, which can balance the buckle 1 so that it has a stable rotation center.

[0037] Furthermore, a gripping groove 51 is provided on the top of the bubble breaker 5 , which facilitates the application of force when disassembling the bubble breaker 5 and facilitates faster disassembly of the bubble breaker 5 .

[0038] Furthermore, a rotation shaft extending upward is provided on the top wall of the liner 2, and the connecting rod 33 is rotatably connected to the rotation shaft. The connecting rod 33 and the liner 2 have the same rotation center, and the two rotate synchronously.

[0039] Furthermore, the wall of the strip hole 331 where the teeth 332 are located is an arc-shaped structure. When the gear 32 meshes and rotates along the teeth 332, it can drive the linkage rod 33 to rotate, thereby driving the lock buckle 1 to rotate, and realizing automatic locking and unlocking.

[0040] Furthermore, a blocking curtain 211 is provided on the hole wall of the avoidance hole 41, and the top of the lever 11 passes through the blocking curtain 211.
