[0022] Specifically, in this utility model, when the hydraulic cylinder 6 is working, it pushes the connecting rod 8. Through the transmission of the connecting rod 8, the movable rod 7 can rotate around the carrier body 1. The push wheel 9 at the upper end of the movable rod 7 pushes the lifting support platform 3, thereby enabling the lifting support platform 3 to move vertically. When the motor 41 is working, it drives the shaft 42 to rotate, and the shaft 42 drives the drive wheel 43 to rotate. Through the cooperation between the drive wheel 43 and the driven wheel 45, the transmission belt 46 can transport goods. When the threaded rod 472 is rotated, the threaded rod 472 can drive the U-shaped mounting bracket 473 to move. Through the transmission of the U-shaped mounting bracket 473, the tension wheel 474 also moves. By adjusting the position of the tension wheel 474, the tension of the transmission belt 46 can be adjusted.
