When the connecting plate 75 moves, it drives the bottom folding plate 77 to rotate around the hinge of the bottom folding plate 77 and the connecting plate 75. At the same time, the hinge of the bottom hinged plate 76 and the bottom folding plate 77 lifts the bottom surface of the cloth bag 6, and the cloth bag 6 is also folded. A sliding rod 78 runs through the middle of the back plate 2 and is slidably connected at the penetration point. The two ends of the sliding rod 78 pass through the left end of the bottom plate 1 and are rotatably connected at the penetration point. The trolley component 7 is hinged to each other in an ingenious manner through multiple groups of plates. This design enables the hinged plates to be tightly and firmly surrounded into a complete box body. Most of these plates are designed to be semi-hollow.
