At the same time, by releasing the clamping and fixing of the inner wall of the shell body 23, the shell body 23 can be easily removed from the support base 22. The clamping mechanism fixes the inner wall of the shell body 23. Therefore, during the grinding process, each surface of the shell body 23 can be fully in contact with the grinding head 20. There will be no dead angle during the grinding process, which avoids repeated grinding of the shell body 23 and improves the grinding efficiency of the device. The grinding head 20 is used to grind and polish the surface of the shell body 23. The support The bottom end of the column 21 is driven by a motor. When working, when the polished shell body 23 is to be removed from the supporting base 22, the shift block 26 is first pushed upward, and the connecting spring 27 fixed at the bottom end of the shift block 26 will be stretched. A first connecting rod 28 is fixed to the rear end of the shift block 26. When the first connecting rod 28 moves upward, the first connecting rod 28 will pull the first push rod 31 connected to the bottom end, thereby driving the disc 32 to rotate through the first push rod 31. Since the driving gear 34 and the first pulley 37 are fixed to the disc 32, the driving gear 34 and the first pulley 37 will also rotate synchronously, and the driving gear 34 and the first pulley 37 will rotate synchronously.

During operation, the top end of the first connecting rod 28 is connected to the movable plate 29, thereby driving the movable plate 29 to move upward. Four groups of fixing columns 30 are fixed on the movable plate 29. The top part of the fixing columns 30 is inserted in the support base 22 and kept horizontal with the top end of the support base 22, so that the shell body 23 is placed on the support base 22. When the fixing columns 30 move upward, the top end of the fixing columns 30 will push the inner wall of the shell body 23, thereby lifting the shell body 23 so that the inner wall of the shell body 23 is smoothly separated from the support base 22, so as to facilitate the removal of the shell body 23 from the support base 22.
