The transmission lever 202 is connected to the traction disc 203. When the transmission lever 202 is pushed, the traction disc 203 and the transmission shaft 201 slide together, thereby driving the traction disc 203 to connect with the transmission unit of the traveling assembly 10, thereby driving the traction disc 203 to rotate. One end of the traction cable is mounted on the traction disc 203, and the other end is fixed to the target point. By driving the traction disc 203 to rotate, the transport device is assisted in moving in the transport direction.
