A limiting plate 14 is slidably connected to the inner wall of the base 1. A rotating rod 16 is rotatably connected to the inner side of the limiting plate 14. An adjusting mechanism 2 is arranged on the inner wall of the base 1. A rotating shaft is rotatably connected to the inner wall of the base 1. The outer end of the rotating shaft is drivingly connected to a conveyor belt 12. An elastic anti-slip belt 15 is fixedly connected to the surface of the conveyor belt 12.
