[0018] Furthermore, the rotating gear includes a one-way gear located in the middle and large gears arranged on both sides of the one-way gear, and keyway holes are opened on the one-way gear and the large gear.

[0019] Furthermore, the anti-retraction plate includes an anti-retraction strip and an anti-retraction screw. The anti-retraction plate is fixedly mounted on the base through the anti-retraction screw and the mounting hole. One end of the anti-retraction plate is arranged on the nut end of the anti-retraction screw, and one end of the anti-retraction plate is used to cooperate with the one-way gear.

[0020] Furthermore, a notch for fixing sandpaper is respectively provided at both ends of the transmission shaft, a key is provided on the outer circumferential surface of the transmission shaft, and the transmission shaft is connected to the rotating gear through the key and the key slot hole.

[0021] Furthermore, the adjustable backer is provided with a plurality of oblong holes, and the adjustable backer is fixed to the opening slot of the adjustable backer by means of backer screws passing through the oblong holes and the threaded holes.

[0022] In summary, the present invention has the following beneficial effects:

[0023] Sandpaper rewinding grooves are provided at both ends of the base, through which the sandpaper is rewound to ensure that only the edges and corners are sanded. An adjustable backrest is installed at the lower part of the base to adapt to different sanding angles. When in use, the effective part of the sandpaper is updated by turning the rotating gear, and the stop plate clamps the rotating gear to prevent reverse rotation, ensuring forward rotation.
