In the first state, that is, when the elastic member 213 is not subjected to an external force, the front ends of the first connection portion 211 and the second connection portion 212 are closed, and the rear ends are opened. When the rear ends of the first and

second connection parts

211 and 212 are closed by an external force applied thereto, the front ends are opened. The front ends of the first connecting portion 211 and the second connecting portion 212 are respectively provided as a first buckling claw 2111 and a second buckling claw 2121, and in the first state, the first buckling claw 2111 and the second buckling claw 2121 are buckled together in a butt joint manner, so that the front ends of the first connecting portion 211 and the second connecting portion 212 form an accommodating space for buckling the embedding device 31. The first locking claw 2111 and the second locking claw 2121 are provided with guiding structures configured to be coupled with the engaging device 31. When the first slider 2 and the second slider 3 are connected together, the fitting device 31 can move along the guide structure, an external force is applied to the first connecting portion 211 and the second connecting portion 212, so that the front ends of the first connecting portion 211 and the second connecting portion 212 are opened, the fitting device 31 enters the accommodating space formed by the front ends of the first connecting portion 211 and the second connecting portion 212, at this time, the force applied by the fitting device 31 disappears, the first connecting portion 211 and the second connecting portion 212 recover to the first state, and the front ends are closed to realize the fastening of the fitting device 31. The guide structure may be provided as a triangular or other arcuate open guide structure.

The rear ends of the first connecting portion 211 and the second connecting portion 212 are provided with matching surfaces suitable for matching with the first unlocking mechanism 4, so that when the first unlocking mechanism 4 is contacted and moves relatively, the front ends of the first connecting portion 211 and the second connecting portion 212 rotate relatively to be opened to realize unlocking. In the present embodiment, the outer sides of the rear ends of the first connection portion 211 and the second connection portion 212 are respectively provided with first
