The two groups of long belts 8 are connected by a rotating shaft, and the rotating shaft is respectively arranged at the center of the two first pulleys 82 and the center of the two second pulleys 81. The two ends of the rotating shaft arranged at the center of the first pulley 82 are rotatably connected to the second groove body 53.
