[0039] The second pulley 3 is rotatably connected to the fixed mounting portion 1b about a longitudinal horizontal axis. More specifically, the fixed mounting portion 1b includes a vertical plate and a horizontal plate on the back of the vertical plate. The horizontal plate is used for fixedly connecting to the frame body 1a, and the vertical plate is used for rotatably connecting the first pulley 2 and the second pulley 3. The first pulley 2 and the second pulley 3 are respectively on both sides of the horizontal plate, one above the other.

[0040] The third pulley 4 is rotatably connected to the movable mounting portion 1c about a longitudinal horizontal axis.

[0042] The adjusting mechanism 6 is arranged between the fixed mounting portion 1b and the movable mounting portion 1c, so that the abrasive belt 5 can be switched between a tightened state and a loosened state. That is, when using the abrasive belt 5 for grinding, the abrasive belt 5 is in a tightened state, and when the abrasive belt 5 needs to be replaced, the abrasive belt 5 is switched to a loosened state.

[0043] Please refer to Figure 3 , the movement of the movable mounting portion 1c relative to the fixed mounting portion 1b can be swinging or sliding. In some embodiments, the movement of the movable mounting portion 1c relative to the fixed mounting portion 1b is horizontal sliding along the transverse direction. More specifically, a group of optical axes 1c1 are fixedly connected to the movable mounting portion 1c, linear bearings matching the optical axes 1c1 and a first connecting block 1b1 for connecting the optical axes 1c1 are arranged on the fixed mounting portion 1b, and the first connecting block 1b1 can press and fix or loosen the optical axes 1c1 through bolts.
