[0018] As preferred, the two ends of the long-side side plate in the length direction are provided with fourth inclined edges, and the fourth inclined edges cooperate with the locking block.

[0019] By adopting the technical scheme, the fourth inclined edge plays a guiding role, avoids interference between the top of the long-side side plate in the length direction and the locking block when the short-side side plate and the locking block wrap the side of the long-side side plate, and can accommodate a certain inward deformation.

[0020] As preferred, the plate body is a top plate or a bottom plate, and the plate body is rectangular.
