[0036] In this embodiment, the top of the column 5 is rotatably connected to the middle position of the bottom surface of the workbench 4, and the rotation direction is the same as the rotation direction of the arc-shaped gear ring 21; a mounting groove 51 is provided on the column 5, and the mounting groove 51 penetrates the column 5 in the left-right direction, and side walls are provided in the front-back direction.

[0038] In this embodiment, the limiting hole 52 and the limiting groove 53 are symmetrically arranged in the front-to-back direction of the column 5, and the inner wall of the limiting groove 53 is provided with a thread;

[0039] When the arc-shaped gear ring 21 is rotated to a suitable position, the limiting screw 6 is sequentially passed through the limiting hole 52, the mounting groove 51 and the threaded hole 211 on the arc-shaped gear ring 21 and then threadedly sleeved with the limiting groove 53.

Since the first screw 12 is threadedly sleeved with the bracket 11, and the first screw 12 is rotatably connected to the clamping plate 13 through a bearing, the clamping plate 13 does not rotate when the first screw 12 is rotated, but only translates in the direction of approaching each other until the clamping plate 13 stably clamps the automobile parts. The structure of the present application is simple, and the threaded connection method between the first screw 12 and the bracket 11 is structurally stable, which improves the stability of clamping compared to clamping using elastic parts.

[0051] In a preferred embodiment, if Figure 1 As shown, a first rotating handle 23 is provided on the driving gear 22. A second rotating handle 33 is provided on the second gear 32. Specifically, the first rotating handle 23 and the second rotating handle 33 facilitate the rotation of the driving gear 22 and the second gear 32 in a manual driving state.
