The dust and debris generated during the cutting of the plate are sucked into the collecting box 109 through the dust collection frame 108, the inner tube 107, and the outer tube 103 for storage. When it is necessary to process plates of different thicknesses, the staff rotates the screw 106, and the outer shell 104 provides guidance for the moving column 105. The rotation of the screw 106 causes the moving column 105 to slide longitudinally along the outer shell 104, and the moving column 105 drives the dust collection frame 108 to move longitudinally. According to the thickness of the processed plate, the dust collection distance between the dust collection frame 108 and the plate is changed by adjusting the height position of the dust collection frame 108, thereby improving the dust adsorption effect.
