By providing the rotatable rotating base 8 on the first clamping part 7 of the first clamping part 2, when the workpiece is placed on the placing surface and the second clamping part 6 clamps the workpiece together with the placing surface, the worker can keep a certain distance from the grinding tool during the grinding process, so as to avoid the grinding tool from scratching the worker. At the same time, during the grinding process, the worker controls the clamping force between the rotating base 8 and the second clamping part 6, so that the rotating base 8 can drive the workpiece to rotate, avoiding the worker from stopping the grinding action and adjusting the edge to be ground of the workpiece. By providing the rotating base 8 on the first clamping part 7, the grinding efficiency can be improved.

[0024] In the embodiment, the extension line of the rotation axis of the rotating base 8 is perpendicular to the placement surface, so that the shape of the workpiece grinding clamping tool can be more processed and the stability of the cooperation between the placement surface and the second clamping part 6 when clamping the workpiece can be improved.

[0025] In the embodiment, the contact position of the first clamping part 7 and the placement surface is located on the extension line of the rotation axis of the rotating base 8. In this way, the workpiece can be rotated around the rotation axis of the rotating base 8 during the grinding of the workpiece, and the grinding precision of the workpiece can be improved.

In some embodiments, the mounting surface of the rotating base 8 is provided with a rotating hole, and the second clamping part 6 is provided with the rotating shaft 9 accommodated in the rotating hole. The rotating manner of the rotating base 8 arranged on the first clamping part 7 can be adjusted according to actual needs. In the embodiment, the placement surface side of the rotating base 8 is provided with a weight-reducing recess, the bottom of the weight-reducing recess is provided with a through hole, a screw passes through the through hole and enters the rotating hole to rotatably arrange the rotating base 8 on the first clamping part 7, and the screw head is clamped on the side of the through hole away from the rotating hole. At this time, the screw rod is the rotating shaft 9. It should be noted that the placement surface is a virtual surface, that is, the surface of the rotating base 8 with the weight-reducing recess opening is the placement surface, and the size of the clamped workpiece should be larger than the opening size of the weight-reducing recess. In some embodiments, the rotating base 8 is not provided with a weight-reducing recess. The design of the rotating base can be set according to actual needs.

[0027] In the embodiment, the first clamping part 7 of the first clamping piece 2 is arranged towards the second clamping part 6, the second clamping part 6 of the second clamping piece 3 is arranged towards the second clamping part 6, that is, the first clamping part 7 and the second clamping part 6 are oppositely arranged, the overlapping part between the first clamping piece 2 and the second clamping piece 3 is the rotating connection part 4, the part between the rotating connection part 4 and the first clamping part 7 on the first clamping piece 2 is the supporting part 5, and the part between the rotating connection part 4 and the second clamping part 6 on the second clamping piece 3 is also the supporting part 5. The first clamping part 7 and the corresponding supporting part 5 form an L shape, and the second clamping part 6 and the corresponding supporting part 5 form an L shape. In this way, the interference between the supporting part 5 and the workpiece during the clamping of the workpiece can be avoided, and the practicability of the workpiece grinding clamping tool during use can be improved.

The reset elastic piece 10 can replace part of the labor, and the labor can be saved.

[0029] In the embodiment, the first clamping member 2 and the second clamping member 3 are both in strip shape, one end of the first clamping member 2 is the first clamping part 7, the other end of the first clamping member 2 is the holding part 1, one end of the second clamping member 3 is the second clamping part 6, the other end of the second clamping member 3 is also the holding part 1, and the reset elastic member 10 is arranged between the holding parts 1 of the first clamping member 2 and the second clamping member 3. On the first clamping member 2, the holding part 1 and the supporting part 5 are respectively located on both sides of the first clamping member 2 corresponding to the rotating connecting part 4; on the second clamping member 3, the holding part 1 and the supporting part 5 are respectively located on both sides of the second clamping member 3 corresponding to the rotating connecting part 4.
