Three mutually parallel strip-shaped wooden squares are fixed at the bottom of the pallet. A square frame is fixed on the upper side of the pallet. The square frame is made of steel pipes with a rectangular cross-section. Strip-shaped holes are opened on the outer side of the square frame. The lower edge of the surrounding board is fixed with a Z-shaped plug-in part, and the Z-shaped plug-in part is inserted into the strip-shaped holes to connect the surrounding board to the square frame. The upper cover covers above the four surrounding boards and is removed from the four surrounding boards. This utility model adopts an assembled structure. When unpacking, first remove the upper cover, and then turn the surrounding board outwards to remove the surrounding board, so that all the goods are exposed for easy transfer of the goods.
