Since the driving wheel 8 is provided with external teeth meshing with the internal teeth 5 of the conveyor belt 7, the rotation of the driving wheel 8 will drive the conveyor belt 7 to make continuous and stable linear motion along the set path through meshing. The driven wheels 9 at both ends of the conveyor belt 7 are movably connected to the inner walls on both sides of the frame 1.
