In fact, the first partition 150 stands on one side of the protection seat 100 in the second horizontal direction, and the first fastening component 160 is protruding on the inner sidewall of the first partition 150 in the second horizontal direction. In this embodiment, the first buckle assembly 160 includes two first buckles 161, the two first buckles 161 are disposed on the inner side wall of the first partition 150 at intervals along the first horizontal direction, and the openings of the two first buckles 161 are all vertically upward, and the two first buckles 161 and the first partition 150 enclose the first limiting channel 120.

In practical application, the connecting piece is vertically embedded into the first limiting channel 120 downwards from the openings of the two first buckles 161, so that the limiting and fixing of the connecting piece in the first limiting channel 120 can be realized, and the first baffle 150 and the two first buckles 161 realize the limiting of the two sides of the connecting piece in the second horizontal direction. One end of the connecting piece extends out of the first limiting channel 120 from the first introducing end 121, and then bends towards the second horizontal direction, so that the connecting piece can extend into the assembling space 110, and the bending part of the connecting piece at the first introducing end 121 is limited by the first introducing end 121 in the first horizontal direction.
