Under the cooperation of the first bevel gear 314 and the second bevel gear 313, the lead screw 39 rotates to make the ball nut 310 rise. The ball nut 310 drives the front side sliding sleeve 35 to rise through the connecting rod. Under the cooperation of the active rod 37 and the driven rod 36, the rear side sliding sleeve 35 is pulled. While the sliding sleeve 35 slides, it drives the sliding rods 33 to approach each other, so that the two folding seats 31 approach each other. The two enclosing plates 34 approach each other together with the folding seats 31, pressing the pocket cloth 5. While the two folding seats 31 approach each other, they squeeze the bearing plate 311, causing the bearing plate 311 to flip upwards around the rotating shaft, so as to fold the two bearing plates 311 together, thus completing the folding process of the entire device. When the device is needed to transship the express delivery, reverse the motor 315 to make the sliding sleeve 35 move downwards, driving the two folding seats 31 to move away from each other, and at the same time driving the bearing plate 311 and the pocket cloth 5 to unfold. The bearing plate 311, the enclosing plate 34 and the pocket cloth 5 form a storage space, so as to be able to carry the express delivery for transshipment. Pull the cover cloth 45 through the roll-up cover beam 46, make the winding shaft 42 rotate to release the cover cloth 45, hook the hook 47 on the fixed rod 8, so that the cover cloth 45 can cover the storage space. When the winding shaft 42 rotates, it drives the coil spring 44 to wind inwards. When the hook 47 is removed from the fixed rod 8, the coil spring 44 rebounds under the action of the tension generated during winding, driving the runner 43 and the winding shaft 42 to reverse, so that the cover cloth 45 and the roll-up cover beam 46 return to their original positions.
