The body is provided with an abutting part, and the abutting part is one side edge of the abdicating hole 15. A mounting cavity is formed inside the insertion part 14, and an inwardly extending flange is formed at a middle position of the mounting cavity in the first direction along the circumferential direction.

The body is provided with a chute 121 extending along a first direction. Specifically, as shown in fig. 2, a plurality of connecting ribs extend inwards from the edge of the opening of the installation cavity, the connecting ribs converge at the middle position above the installation cavity to form a chute seat 12, and the side wall of the chute seat 12 is formed with the chute 121 in the first direction. Specifically, two sliding grooves 121 are uniformly arranged along the circumferential direction of the sliding groove seat 12.
