[0011] Preferably, the extension groove is configured as an inclined structure.

[0012] Preferably, a transition angle is provided at one end of the folded portion.

[0013] Technical effects and advantages of the utility model:

[0014] 1. The utility model provides a first cover plate and a second cover plate at both ends of the box body, and the middle parts of the first cover plate and the second cover plate are provided with a card slot, and the first cover plate and the second cover plate can be mutually engaged through the card slot to realize the assembly and sealing of the box body, thereby completing the packaging of the box body without using an adhesive tape, facilitating the recycling of the box body, and achieving an environmentally friendly effect;

[0015] 2. The utility model provides a folding portion inside the box body, and the folding portion is fixed to the plug plate through a slot. When the size of the box body needs to be adjusted, the position of the plug plate can be adjusted to release the limit of the folding portion, and the folding portion can be unfolded to achieve the expansion of the box body size. After the folding portion is unfolded, the first cover plate and the second cover plate can be connected end to end to seal the unfolded box body, thereby achieving the box body size adjustment while ensuring the integrity of the box body structure.
