Three first support frames 2 are provided on both sides of the front and rear of the top of the base plate 1, and a slide rail 3 is provided between the tops of the three first support frames 2 on the same side in the lateral direction. A movable disk 4 is slidably provided between the left sides of the slide rails 3, and a first support plate 5 is provided on the left side of the top of the slide rail 3. The first movable blocks 7 are slidably provided on the upper inner parts of the first support plates 5, and toothed disks 6 are rotatably provided between the lower inner parts of the first movable blocks 7. Four groups of grinding stones 8 are evenly spaced and slidably provided at the bottom of the toothed disk 6, and the number of each group is 2. Two first springs 9 are provided between the outer side of the grinding stone 8 and the toothed disk 6, a power mechanism 10 is provided on the first movable block 7 on the front side, and a clamping mechanism 11 is provided on the movable disk 4.

[0068] The power mechanism 10 includes a second support frame 1001, a motor 1002 and a first full gear 1003. The second support frame 1001 is provided on the upper rear side of the first movable block 7 on the front side, and the motor 1002 is provided on the inner side of the second support frame 1001. The first full gear 1003 is provided on the output shaft of the motor 1002, and the first full gear 1003 is meshed with the gear disc 6.

[0069] The clamping mechanism 11 includes a clamping plate 1101, a first movable rod 1102 and a second spring 1103. The first movable rod 1102 is symmetrically slidably arranged on the upper right side of the movable disk 4. The clamping plate 1101 is arranged between the left side of the first movable rod 1102, and a second spring 1103 is arranged between the right side of the first movable rod 1102 and the movable disk 4.

[0070] When people need to polish and grind the round tube, first pull the toothed disc 6 upwards, the toothed disc 6 drives the first movable block 7, the grinding stone 8 and the first spring 9 to move upwards, the first movable block 7 drives the second support frame 1001, the motor 1002 and the first full gear 1003 to move upwards, and then pull the movable disc 4 to the right, drive the first movable rod 1102 and the clamping plate 1101 to move to the right, when the movable disc 4 moves to the rightmost, fix the movable disc 4, and then pull the clamping plate 1101 to the left, drive the first movable rod 1102 to move to the left, compress the second spring 1103, and then the round tube is polished. The tube is placed on the movable disk 4, and then the clamping plate 1101 is released, and the second spring 1103 returns to its original state, driving the clamping plate 1101 and the first movable rod 1102 to move to the left and reset, so that the clamping plate 1101 and the movable disk 4 clamp the round tube, and then push the movable disk 4 to the left to reset, driving the first movable rod 1102 and the clamping plate 1101 to move to the left and reset, thereby driving the round tube to move to the left. When the movable disk 4 moves to the leftmost, stop pushing the movable disk 4, and then release the toothed disk 6. Under the action of gravity, the toothed disk 6 drives the first movable block 7, the grinding stone 8 and the first spring 9 to move downward and reset. The first movable block 7 drives the second support frame 1001, the motor 1002 and the first full gear 1003 to move downward and reset. When the grinding stone 8 contacts the round tube, the round tube squeezes the grinding stone 8 to move outward, and the first spring 9 is compressed. Under the action of the first spring 9, the grinding stone 8 is close to the round tube, and then the motor 1002 is started. The output shaft of the motor 1002 drives the first full gear 1003 to rotate. The first full gear 1003 drives the toothed disc 6 and the grinding stone 8 to rotate, so that the grinding stone 8 polishes the round tube. After polishing, the motor 1002 is turned off, and the first full gear 1 003. The toothed disc 6 and the grinding stone 8 stop rotating, and then the toothed disc 6 is pulled upwards again to separate the grinding stone 8 from the round tube, and the first spring 9 returns to its original state, driving the grinding stone 8 to move inward and reset, and then the movable disc 4 is pulled to the right again, driving the first movable rod 1102 and the clamping plate 1101 to move to the right, so that the clamping plate 1101 releases the polished round tube again, and then people manually take out the polished round tube, put in the next round tube, and then push the movable disc 4 to the left to reset, and then release the toothed disc 6, repeat the above operation, and the round tube can be polished again.
