The plurality of jaws 312 are allowed to switch between an open state and a closed state when rotated relative to the push rod 311.

When the clamping jaw 312 extends out from the guide 20, the clamping jaw 312 rotates in a direction away from the central axis of the push rod 311 because the clamping jaw 312 is not supported by the hole wall of the through hole 21, so that the clamping jaws 312 are in an open state, and the size of the formed containing space 3121 is enlarged, so that the containing space 3121 with the enlarged size is convenient for containing accessories to be assembled; when the clamping jaw 312 is completely accommodated in the guide 20, the clamping jaw 312 is supported by the hole wall of the through hole 21 and rotates towards the direction close to the central axis of the push rod 311, so that the clamping jaws 312 are in a folded state, and the size of the formed accommodating space 3121 is reduced, thereby the size of the accommodating space 3121 is reduced, and the fitting to be assembled is convenient to clamp.
