[0031] Furthermore, the grinding mechanism also includes a C-shaped plate 5 and a grinding knife 6. The C-shaped plate 5 is fixedly mounted on the left end of the electric push rod 4, and the two vertical plates of the C-shaped plate 5 are slidably sleeved on the inner surface of the vertical plate of the N-shaped plate 3. The grinding knife 6 is fixedly mounted on the left surface of the horizontal plate of the C-shaped plate 5. When the linkage device for mirror processing of the ceramic shaft core is used, the ceramic shaft core is sleeved on the outer surface of the four fixed plates. At this time, by rotating the knob 11, the knob 11 drives the threaded rod 10 fixedly mounted on the front surface to rotate. At this time, the sliding block 12 threadedly sleeved on the outer surface of the threaded rod 10 continues to move forward through the thread set on the outer surface of the threaded rod 10. At the same time, the sliding block 12 drives the eight support rods 13 connected to the outer surface to move forward, and the eight support rods 13 are gradually arranged vertically while moving forward. At the same time, the eight support rods 13 apply a thrust to the opposite side to the fixed plate 14 connected to the rotation at the end away from the sliding block 12, so that it gradually expands outward.

[0032] Working principle: When the linkage device with mirror-finished ceramic shaft core is used, the ceramic shaft core is sleeved on the outer surface of the four fixed plates. At this time, by turning the knob 11, the knob 11 drives the threaded rod 10 fixedly installed on the front surface to rotate. At this time, the sliding block 12 sleeved on the outer surface of the threaded rod 10 continues to move forward through the threads set on the outer surface of the threaded rod 10. At the same time, the sliding block 12 drives the eight support rods 13 connected to the outer surface to move forward, and the eight support rods 13 are gradually arranged vertically while moving forward. At the same time, the eight support rods 13 exert a reverse force on the fixed plate 14 connected to the rotation at the end away from the sliding block 12. Thrust, so that it gradually expands outward, and at the same time, the fixed plate 14 drives the four limit plates 15 fixedly installed on the rear surface to slide in the slide groove 9. The setting of the limit plates 15 prevents the sliding block 12 from rotating following the threads set on the outer surface of the threaded rod 10. After the fixation is completed, the electric push rod 4 is started to apply a leftward thrust to the C-shaped plate 5 fixedly installed on the left end to make it slide to the left.
