The power component drives the two ends of the polishing wheel 1 to move synchronously and the polishing wheel 1 to move vertically up and down, ensuring that the polishing wheel 1 always remains horizontal when adjusting its height; a pusher 8 is fixedly connected to the fixed frame 2 to push the driving component to move horizontally, and the pusher 8 is a cam that can adapt to changes in the height of the polishing wheel 1.

[0021] See Figures 1 to 4 Preferably, the power component of this utility model is located at the output end of the secondary drive component 51, the secondary drive component 51 is fixedly connected to the fixed frame 2, and the power component drives the two racks 6 to move synchronously to ensure that the two ends of the polishing wheel 1 move at the same height.

[0022] See Figures 1 to 4 In addition, the power component of this utility model is a drive wheel 5, which is fixedly connected to one end of the rotating shaft 71. The drive wheel 5 meshes with a rack 6. The other end of the rotating shaft 71 is fixedly connected to an idler wheel 7, which meshes with a rack 6. The rotation of the idler wheel 7 can drive the rack 6 to move. The two racks 6 are respectively fixedly connected to the two ends of the polishing wheel 1.

[0023] In the specific implementation process: the drive wheel 5 meshes with the rack 6, and the idler wheel 7 has the same diameter as the drive wheel 5. The two vertical racks 6 are symmetrical to ensure that when the drive wheel 5 drives the idler wheel 7 to rotate, the two racks 6 drive the two ends of the polishing wheel 1 to move synchronously, ensuring that the polishing wheel 1 always remains horizontal.

[0024] See Figures 1 to 4 Even better, the polishing wheel 1 of this utility model is rotatably connected to bearing seats 11 at both ends, and the two bearing seats 11 are slidably connected to the fixed frame 2.
