The clamping mechanism and the fixed mechanism can further fix the toothed ring body, which can greatly improve the clamping effect of the device, thereby facilitating subsequent drilling and other processing steps of the toothed ring.

[0007] Preferably, the extrusion rod is provided with a rubber block at the lower end. When the second extrusion block moves down, the rubber block can further fix the toothed ring body from the upper end of the toothed ring body, thereby improving the fixing effect of the toothed ring body.

[0008] Preferably, the first extrusion block and the second extrusion block are mutually attached to the outer side surfaces of the inclined surfaces, and the first extrusion block is extruded by the second extrusion block when the second extrusion block moves downward, so that the first extrusion block and the clamping block are forced to move towards the gear ring body, and the gear ring body is clamped and fixed by the clamping block, thereby facilitating subsequent processing steps.

[0009] Preferably, a spring is arranged on one side of the sliding groove, and the first clamping block is automatically pushed away from the gear ring body by the spring, so that the clamping blocks are pushed away from each other by the spring when the second extrusion block no longer extrudes the first extrusion block, and the gear ring body is no longer clamped.

[0010] Preferably, the lower end of the connecting rod is fixedly provided with a connecting frame, and the lower end of the connecting frame is provided with an electric push rod, and the movable end of the electric push rod is fixedly connected with the connecting frame.
