A forklift slot is also provided on the base frame to facilitate forklift transportation. The four corners of the top of the base frame are hinged with base frame columns, and the bottoms of the two side panels are respectively plugged with the four base frame columns. The sides of the two sides of the base frame close to the front are fixedly connected with latch bodies, and the backs of the two base frames close to the front are respectively fixedly connected with pin tubes corresponding to the two latch bodies. The two latch bodies are respectively plugged with the two pin tubes. Two mounting plates are fixedly connected to the lower parts of the opposite sides of the two side panels, and the four mounting plates are respectively fixedly connected to the base frame columns through pin shafts. When the latch bodies are separated from the pin tubes, the side panels can be folded, thereby facilitating the folding and storage of the side panels.
