Through adopting above-mentioned technical scheme, the handle can provide application of force position point, makes things convenient for staff's dismouting retaining ring.

The utility model discloses further configure to: the upper end surface of the workbench is connected with a plurality of stop blocks.

Through adopting above-mentioned technical scheme, the dog provides the face of keeping off for the magnet, and when the workstation rotated, the magnet had radial butt position point to further promote the stability of magnet when processing.

The utility model discloses further configure to: the two ends of the stop block are arc-shaped and are attached to the inner circumferential surface of the check ring.

Through adopting above-mentioned technical scheme, the arc can promote the laminating degree with the retaining ring.

To sum up, the utility model discloses a following at least one useful technological effect:

1. the upper end of the retainer ring is higher than the surface of the workbench, so that a stop ring is formed on the circumferential surface of the upper end surface of the workbench. When the working table rotates to make the magnet deviate, the retainer ring can limit the processed magnet in the working table, thereby preventing the magnet from being thrown out of the working table.

2. The rubber ring is pressed and deformed with the butt of annular inner wall when retaining ring insert ring groove, because the rubber ring has elasticity, it has the trend of recovering deformation all the time, and the global inner wall with the annular of rubber ring supports tightly all the time promptly. On one hand, the direct friction force between the retainer ring and the annular groove can be increased, and the axial movement trend of the retainer ring is reduced; on the other hand, the rubber ring can improve the sealing property of the ring groove and reduce the chip liquid and chip scale in the ring groove.
