One side of the slider 95 is fixedly connected to a spring 96, and the slider 95 is transmission-connected to one side of the inner wall of the bottom plate 1 through the spring 96. The top of the slider 95 is fixed to the bottom plate 1. The frame 10 is fixedly connected, and the screw rod 92 is driven to rotate by rotating the turntable 94. Since the screw rod 92 is movably connected with the shaft sleeve 91, the screw rod 92 drives the push block 93 to move during the rotation process, pushing the slider 95 and the fixed frame 10 to move rightward along the sliding groove 8 on the bottom plate 1. After the turntable 94 is rotated in the opposite direction to disengage the push block 93 and the slider 95 from the state of active connection, the slider 95 and the fixed frame 10 are reset under the elastic force of the spring 96, realizing the function of fixing the sand belts 16 of different lengths, avoiding the sand belt 16 from not being able to achieve the ideal grinding effect due to not being fastened, and improving the adaptability of the device. The top of the sliding device 9 is fixedly connected with the fixed frame 10 located between the two blocking covers 4, and both ends of one side of the fixed frame 10 are fixedly connected to one end of the back side of the limit pin 11 The limit pin 11 is a metal part with a length of 3 cm. The diameter of the front end of the limit pin 11 is larger than the diameter of the back end. The limit pin 11 limits the position of the rotating wheel 12, so that the sanding belt 16 can rotate stably on the rotating wheel 12, avoiding the position of the rotating wheel 12 not being fixed and affecting the processing accuracy, and improving the rationality of the device.

By turning on the motor 152, the bevel gear I 153 on the output shaft of the motor 152 is driven to rotate. Because the bevel gear I 153 and the bevel gear II 155 are meshed with each other, the bevel gear II 155 and the transmission wheel 156 are driven to rotate coaxially. The rotating wheel 156 drives the sand belt 16 by friction, realizing the function of providing power for the sand belt 16, and improving the mobility of the device. The sand belt 16 is movably connected to the transmission device 15, and the transmission device 15 is connected to the three rotating wheels 12 through the sand belt 16.

[0025] During operation, rotating the turntable 94 drives the screw 92 to rotate. Since the screw 92 is movably connected to the shaft sleeve 91, the screw 92 drives the push block 93 to move during the rotation process, and pushes the slider 95 and the fixed frame 10 to move rightward along the sliding groove 8 on the bottom plate 1 to tighten the sanding belt 16. The limit rod 13 is adjusted left and right to drive the rotating wheel 12 to move left and right inside the limit sleeve 14, and the position of the rotating wheel 12 is adjusted. The angle of the sanding belt 16 is controlled by cooperating with the fixed frame 10 to move. The motor 152 is turned on to drive the bevel gear I153 on the output shaft of the motor 152 to rotate, and the bevel gear II155 and the transmission wheel 156 are driven to rotate coaxially, so that the rotating wheel 156 friction drives the sanding belt 16 to move, and the workpiece to be processed is placed on the workpiece placement plate, and then grinding can begin.
