During the insertion, the extrusion block 13 is inserted into the raised limiting slide grooves at both ends of the cover plate 1. During the continuous insertion of the cover plate 1, when the top surface of the cover plate 1 and the top surface of the box body 7 are on the same plane, the extrusion block 13 moves to the top of the limiting slide groove.
