Claims

1. A sheet of sandpaper, characterized by, include: Support frame, telescopic frame, and drive mechanism; The telescopic frame is movably mounted on the bracket, and the telescopic frame is provided with a sandpaper pressing part; The drive mechanism is mounted on the bracket and is driven by the telescopic frame. The telescopic frame moves closer to and away from the bracket under the drive of the drive mechanism. When the telescopic frame moves away from the bracket, the telescopic frame and the bracket can cooperate to support the sandpaper belt.

2. A paper sheet holder according to claim 1, wherein: The telescopic frame is equipped with a connector, and the telescopic frame is movably connected to the support through the connector; The driving mechanism includes a clamping member, a first elastic member, an operating member, and a second elastic member. The clamping member is movably disposed on the bracket and can move relative to the bracket to press against and disengage from the connecting member. The first elastic member is connected to both the clamping member and the bracket. When the clamping member disengages from the connecting member, the first elastic member undergoes elastic deformation. The operating member is movably disposed on the bracket and drivenly connected to the connecting member. The second elastic member is connected to both the connecting member and the bracket. When the connecting member, driven by the operating member, moves the telescopic frame away from the bracket, the second elastic member undergoes elastic deformation.

3. A paper sheet holder according to claim 2, wherein: The clamping member includes a first rotating plate and a clamping plate. Both the first rotating plate and the clamping plate are rotatably engaged with the bracket. The first rotating plate is located on one side of the bracket and can rotate outward from the bracket. The clamping plate presses against the connecting member and can disengage from the connecting member under the drive of the first rotating plate. The first elastic member is connected to the clamping plate and the bracket respectively.

4. A paper sheet holder according to claim 3, wherein: The clamping plate is provided with a connecting hole, the connector passes through the connecting hole, and the clamping plate presses against the connector through the inner wall of the connecting hole.

5. A sandpaper holder according to claim 2, characterized in that: The operating component includes a second rotating plate and a fixed plate. The second rotating plate is rotatably engaged with the bracket. The fixed plate is disposed on the connecting member. The second rotating plate presses against the fixed plate. The second elastic member is connected to the connecting member by connecting with the fixed plate. When the second rotating plate rotates, it pushes the fixed plate to move the connecting member.

6. A paper sheet holder according to claim 5, wherein: The second rotating plate is provided with two pushing parts, which are located on both sides of the connector and abut against the fixed plate.

7. A sheet of abrasive paper according to any one of claims 1 to 6, wherein: The telescopic frame is detachably connected to the support frame.

8. A sheet of abrasive paper according to any one of claims 1 to 6, wherein: The cross-section of the sandpaper pressing part is arc-shaped, rounded, planar, or angled, and the angle of the angled part is greater than 0° and less than 180°.

9. A sheet of abrasive paper according to any one of claims 1 to 6, wherein: The telescopic frame is provided with a clearance groove for sandpaper belts and the structure to be sanded to extend into.

10. A paper sheet holder according to any one of claims 1 to 6, wherein: The telescopic frame is equipped with elastic pressure pads for supporting the sandpaper.
