The top end of the inner side of the working box 8 is fixedly connected to the top end of the second electric telescopic rod 9. The bottom end of the second electric telescopic rod 9 is fixedly connected to the upper surface of the fixed block 10. The lower surface of the fixed block 10 is rotatably connected with the roller 11. Start the second electric telescopic rod 9, so that the second electric telescopic rod 9 drives the fixed block 10 to move downward, so that the fixed block 10 and the roller 11 press the paper to prevent the paper from moving.

[0028] The upper end and the lower end of one side of the interior of the working box 8 are rotatably connected to one end of the rotating rod 13, and the other end of the rotating rod 13 is fixedly connected to the output end of the second motor 12. The second motor 12 is started, so that the second motor 12 drives the rotating rod 13 to rotate on both sides of the interior of the working box 8. One side of the second motor 12 is fixedly connected to the other side of the interior of the working box 8. Both ends of the rotating rod 13 are rotatably connected to the upper end of the disc 14.
