The end of the connecting rod 16 away from the rotating shaft 6 is fixedly installed with a fixing plate 5. The fixing plate 5 is L-shaped. One end of the fixing plate 5 overlaps the upper outer wall of the ring 1. The other end of the fixing plate 5 is located at the outer end of the ring 1 and is fixed by fixing bolts 17. Several threaded holes 4 are evenly opened on the outer wall of the ring 1. The fixing bolts 17 pass through the round holes on the fixing plate 5 and are threadedly connected to the inner wall of the threaded holes 4 to fix the fixing plate 5, thereby fixing the rotating shaft 6 at the inner center of the ring 1. The upper and lower ends of the limiting ring 1 2 and the limiting ring 2 7 are flush.

[0023] Several driven rings 9 are provided, and several teeth 10 are evenly fixed on the outer wall of each driven ring 9. The driven rings 9 are evenly placed between the ring 1 and the rotating shaft 6, and are located at the upper end of the limiting ring 2 and the limiting ring 7. At this time, the outer wall of the teeth 10 meshes with the outer wall of the teeth 3 and the toothed ring 8 respectively, limiting the driven ring 9. The limiting ring 2 and the limiting ring 7 are both located outside the inner ring of the driven ring 9. When the item to be polished is placed in the driven ring 9, the item will not contact the limiting ring 2 or the limiting ring 7. At this time, by rotating the rotating shaft 6, the rotating shaft 6 will drive the several driven rings 9 to rotate synchronously.

[0027] Working principle: The base plate 12 is fixedly installed on the mounting platform of the single-sided grinder. The ring 1 is located at the upper end of the grinding disc of the single-sided grinder. Then, the electric push rod 14 is started to drive the ring 1 to move closer to the upper end of the grinding disc, maintaining a certain distance from the upper end of the grinding disc. Then, the item to be ground is placed in the driven ring 9, with the lower end of the item on the grinding disc and the upper end of the item inside the driven ring 9. Then, the motor 19 is started to drive the rotating shaft 6 to rotate. The rotating shaft 6 will drive the driven ring 9 to move the item to be ground on the grinding disc, thereby grinding the item.
