[0018] When the empty shell is pulled to one side along the two sets of slide grooves by the handle rod, the handle rod will slide upward to compress the return spring, so that the L-shaped fixing plate and the connecting plate move upward along the fixing nails. At this time, several cleaning brushes are pulled up and away from the contact with the desktop. Therefore, in the process of moving to one side, the cleaning brush is prevented from contacting with the desktop and pushing the paper scraps to one side, which cannot be effectively sucked and cleaned. When the driving component is working, the outside air will enter through the two corresponding air guide ports at the front and back, blowing the wind wheel and the cleaning brush. When the cleaning component is pulled back by the paper scrap suction component, it will be wiped to avoid impurities or glue sticking in the table groove, which cannot be effectively handled.

[0019] Use the handle bar to pull the shielding cloth out from the partition frame and the chip suction port until it touches the inner wall at the far end of the table trough, then release the handle bar. The pulled shielding cloth will block the upper side of the table trough, and at the same time tighten the clockwork spring pieces on the front and rear sides, cooperate with the drive assembly and the chip suction port to absorb the waste paper scraps, so as to prevent some paper scraps from flying around due to the airflow during the absorption process, thus avoiding secondary processing. After releasing the hand, the shielding cloth will be pulled back by the elastic action of the clockwork spring piece and automatically recovered. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] One end of the empty shell 82 corresponding to the debris suction port 74 is fixedly connected to one end of the shielding cloth 76, the sliding bar 83 is slidably set on the inner side of the sliding groove 81, the fixing nail 84 and the movable opening 87 opened on the connecting plate 85 are slidably set, and the distance between the two connecting plates 85 is sufficient to move inside the empty shell 82, the air guide port 86 corresponds to between the two wind wheels 810, one side of the L-shaped fixing plate 89 blocks the cleaning brush 811, the handle rod 812 passes through the empty shell 82 and is connected to the partition 88, and the reset spring 813 is set between the partition 88 and the upper inner wall of the empty shell 82.

[0036] When the empty shell 82 is pulled to slide to one side along the two sets of slide grooves 81 by the handle rod 812, the handle rod 812 will slide upward to compress the return spring 813, so that the L-shaped fixing plate 89 and the connecting plate 85 move upward along the fixing nail 84. At this time, several cleaning brushes 811 are pulled up and away from the contact with the desktop. Therefore, in the process of moving to one side, the cleaning brush 811 is prevented from contacting with the desktop and pushing the paper scraps to one side, which cannot be effectively sucked and cleaned. When the driving component 9 is working, the outside air will enter through the two corresponding air guide ports 86 at the front and back, blowing the wind wheel 1 810 and the cleaning brush 811. When the cleaning component 8 is pulled back by the paper scrap suction component 7, it will be wiped to avoid impurities or glue sticking in the table groove 3 and unable to be effectively handled.

In the process of paper cutting, the cut paper scraps will fall on the table, which will be troublesome to clean up every time, and it is not conducive to the display of the finished products after cutting. At this time, the electric air pump 97 is started by the control switch 11 to open an electric valve 96 on the air pipe 94 near the collection box 72, and the other one is closed by default, and the branch pipe 95 and the air pipe 94 are connected. The inside of the collecting box 72 is evacuated, and the scraps are sucked through the cooperation of the scrap suction port 74 and the cleaning component 8. In addition, by opening another electric valve 96 and closing the electric valve 96 close to the collecting box 72, the air pipe 94 will extract the airflow in the disc 91, and the external airflow enters the inside of the disc 91 through the air inlet 92, and the airflow speed is controlled to drive the wind wheel 2 93 and the display plate 98 to rotate, so that the paper cutting is placed on the display plate 98 for display and to facilitate the shooting of the finished product; and when the empty shell 82 is pulled to slide to one side along the two sets of slide grooves 81 by the handle rod 812, the empty shell 82 is pulled to slide to one side along the two sets of slide grooves 81. The hand lever 812 will slide upward to compress the return spring 813, so that the L-shaped fixing plate 89 and the connecting plate 85 move upward along the fixing nail 84. At this time, several cleaning brushes 811 are pulled up and away from the contact with the desktop. Therefore, in the process of moving to one side, the cleaning brush 811 is prevented from contacting with the desktop and pushing the paper scraps to one side, which cannot be effectively sucked and cleaned. When the driving component 9 is working, the outside air will enter through the two corresponding air guide ports 86 at the front and rear, blowing the wind wheel 1 810 and the cleaning brush 811. When the cleaning component 8 is pulled back by the paper scrap suction component 7, it is wiped to avoid impurities or The glue sticks to the table groove 3 and cannot be effectively handled; finally, the shielding cloth 76 is pulled out from the partition frame 73 and the chip suction port 74 through the handle rod 812 until it touches the inner wall at the far end of the table groove 3 and then the handle rod 812 is released. The pulled out shielding cloth 76 will block the upper side of the table groove 3, and at the same time, the clockwork spring pieces 78 on the front and rear sides are tightened, and the drive component 9 and the chip suction port 74 are cooperated to absorb the waste paper scraps to avoid some of the paper scraps flying around due to the airflow during the absorption process, thereby avoiding secondary processing. After releasing the hand, the shielding cloth 76 will be pulled back under the elastic action of the clockwork spring piece 78 and automatically recovered.
