When in use, the handheld portion 12 is provided on one side to effectively clamp and fix the sandpaper through the first clamping mechanism, and the other side is provided with a mounting groove 15 directly on the surface of the working platform 11. Figure 1 Schematic diagram of the structure of this embodiment. Figure 1 As shown, when installing the sandpaper 4, first insert one end of the sandpaper 4 from the side of the grinding plate into the installation groove 15, and clamp the sandpaper 4 through the acute angle of the installation groove 15 to fix the sandpaper 4. The sandpaper 4 can also be fixed by other methods.

[0051] Preferably, the clamping mechanism is provided on both sides of the handheld portion 12. Figure 2 Schematic diagram of the structure of this embodiment. Figure 2 As shown, in this embodiment, the clamping mechanism includes a first clamping mechanism and a second clamping mechanism. The first clamping mechanism and the second clamping mechanism are both connected to the hand-held portion 12 and the first clamping mechanism and the second clamping mechanism are respectively located on both sides of the hand-held portion 12. The two ends of the sandpaper 4 are quickly and effectively clamped and fixed by the first clamping mechanism and the second clamping mechanism, which is convenient to use and improves work efficiency.

[0052] When using this multifunctional sanding board for model making that can quickly clamp sandpaper, the sand surface of the sandpaper 4 is facing outward, and the two ends of the sandpaper 4 are quickly fixed on the working platform 11 through the first clamping mechanism and the second clamping mechanism. The bottom of the working platform 11 is set as a sandpaper installation plane 13 to provide the required plane support for sandpaper grinding. By fixing the hand-held part 12 to the upper part of the working platform 11, it is convenient for hand-held use, which is convenient to use and improves work efficiency. Ordinary sandpaper can be used directly to reduce the cost of use.

[0054] The clamping principle is: when in use, the grinding plate body 1, the pressing plate 21, the connecting rod 22 and the handle 23 are set according to the crank rocker structure. The grinding plate body 1 is the frame, the pressing plate 21 is the rocker, and the handle 23 is the crank. Figure 4 Schematic diagram of the structure of the sandpaper installation work in this embodiment. Figure 4 As shown, when in use, the handle 23 is rotated toward the middle of the hand-held portion 12, and the pressing plate 21 is driven by the connecting rod 22 to open to a certain angle, such as Figure 4 As shown, one end of the cut sandpaper is fed into the middle of the opened pressing plate 21 and the main body 1. After the two ends of the sandpaper in the width direction are aligned with the two ends of the sanding plate main body in the width direction, the handle 23 is rotated in the opposite direction. The pressing plate 21 is driven by the connecting rod 22 to press the sandpaper, thereby completing the installation of the sandpaper on one side.

[0055] Continue to rotate the handle 23 of the other clamping mechanism to open the pressure plate 21, and feed the other end of the sandpaper between the pressure plate 21 and the main body 1. At the same time, ensure that the two ends of the sandpaper in the width direction are aligned with the two ends of the sanding plate body in the width direction, and then rotate the handle 23 in the opposite direction to press the pressure plate down and lock it. At this time, the installation operation is completed, the sandpaper is fixed, and the sanding plate can be used for sanding.

[0056] After use, when the sandpaper 4 needs to be removed or replaced, one of the handles 23 can be rotated toward the middle of the handheld portion 12, or Figure 5 As shown, both handles 23 can be rotated toward the middle of the hand-held portion 12 at the same time, and the pressing plate 21 is driven by the connecting rod 22 to open a certain angle to loosen the sandpaper 4, and the sandpaper 4 is removed from the sandpaper installation plane 13, so that the removal of the sandpaper 4 can be quickly completed. It is simple and convenient to use.
