A sliding groove is formed on the surface of the mounting rod 21 , and the surface of the slider 27 is slidably connected to the inner wall of the sliding groove.

[0025] In this embodiment, the belt grinder 1 includes a mounting base, and two rotating rollers are rotatably connected to the top of the mounting base. A sanding belt is transmitted between the two rotating rollers. One end of one of the rotating rollers is fixedly connected to the output shaft of the motor. When the motor is started by the controller, the output shaft of the motor will drive one of the rotating rollers to rotate, thereby driving the sanding belt to grind the workpiece. The belt grinder 1 is a relatively mature grinding equipment in the existing technology.

[0026] The threads of the two moving blocks 221 connected to the bidirectional screw rod 26 are opposite. Therefore, when the bidirectional screw rod 26 is rotated, the two moving blocks 221 will drive the two fixed plates 222 to move toward each other. The opposite sides of the two fixed plates 222 are fixedly connected with rubber pads.
