The bottoms of both ends of the movable plate 9 are provided with connecting plates 12. The two sets of fixed seats 13 are respectively provided at the lower ends of the two sets of connecting plates 12. The two ends of the sanding belt 17 are respectively fixed inside the two sets of fixed seats 13, and the sanding belt 17 is in a relaxed state when not working.

[0032] More specifically, it also includes a driving mechanism arranged on the side plate 5 for driving the reciprocating motion of the movable plate 9. The driving mechanism includes a motor 6 and a turntable 7. The motor 6 is fixedly mounted on the back of the side plate 5. The output end of the motor 6 passes through the side plate 5 and is fixedly connected to the center position of the turntable 7. A slide groove 10 is provided in the vertical direction of the center of the movable plate 9. A first guide wheel 8 is rotatably mounted at the front edge of the turntable 7. The first guide wheel 8 is inserted into the inside of the slide groove 10, and the wheel surface of the first guide wheel 8 contacts the inner wall of the slide groove 10. The second guide wheels 11 are symmetrically rotatably mounted on the upper and lower sides of the side plate 5. The wheel surfaces of the second guide wheels 11 are in contact with the frame of the movable plate 9. Limiting plates 19 are arranged on both sides of the first guide wheel 8 and the second guide wheel 11. The limiting plates 19 on both sides of the first guide wheel 8 are located on both sides of the slide groove 10, and the limiting plates 19 on the second guide wheel 11 are located on both sides of the movable plate 9.
