At this time, the push handle 11 and the caster 10 are used to push the cart to transfer it. When it is transferred to the material dumping position, the hand screw 12 can be loosened to loosen the tight fixation on the cargo box 3. At this time, the handle 8 at the bottom is pulled to make the second pin 5 move backward along the second guide groove 7, so that the first pin 4 automatically moves downward along the first guide groove 6. Finally, the first pin 4 is pressed on the support block 18 and is buffered by the gas spring 17, so that the cargo box 3 is flat. At this time, the contents of the cargo box 3 are The construction materials are dumped, and at the same time, the electric push rod 13 is driven, and the push plate 16 is pulled through the cooperation of the connecting plate 14 and the connecting rod 15, so that the materials in the cargo box 3 are completely pushed out through the push plate 16 to complete the unloading work. At this time, the cargo box 3 is further pulled through the handle 8 on the top, so that the first pin shaft 4 moves along the first guide groove 6, and the second pin shaft 5 moves along the second guide groove 7 synchronously, thereby standing up the cargo box 3. At this time, the hand-tightening bolt 12 is rotated to achieve the fixing effect of the cargo box 3. At this time, the construction materials can be loaded through the cargo box 3 again for transportation and transfer.
