[0029] When in use, by turning the knob 12, the connecting shaft 11 and the rotating shaft 9 are rotated, the rotating shaft 9 rotates the main bevel gear 8, the main bevel gear 8 rotates the secondary bevel gear 7, and the secondary bevel gear 7 rotates the threaded rod 6. Due to the threaded action of the threaded rod 6, the outer ring 5 can be moved, so that the rotating ring 21 is against the workpiece, so that the required contact area can be adjusted according to the diameter of the workpiece, preventing the workpiece from shaking during processing, thereby making the workpiece more stable during processing.

[0030] In this embodiment, a slide bar 13 and a slide groove 14 are provided between the outer ring 5 and the support column 3, and the cooperation between the slide bar 13 and the slide groove 14 limits the outer ring 5;
