[0030] A moving assembly 7 is arranged inside the top plate 3. The bottom of the moving assembly 7 penetrates through the bottom of the top plate 3 and is installed on the top of the protective cover 6. During work, first make the bottom of the bottom plate 1 fit with a flat ground. After the device is placed stably, install the shaft core 4 to be ground inside the rotating assembly 5. Then, grind the outer surface of the shaft core 4 through the grinding assembly 9. When grinding, the rotating assembly 5 drives the shaft core 4 to rotate, and the moving assembly 7 is coordinated to drive the grinding assembly 9 to move. In this way, the grinding assembly 9 can grind the outer surface of the shaft core 4 more comprehensively, and the grinding effect of the device is better. Immediately, during the grinding process, the protective cover 6 blocks the dust and prevents splashing, and an external dust collector is connected to the connecting pipe 8 to absorb and process the dust generated by grinding, so that the device is convenient to use and has strong practicability.
