[0031] During operation, the bumper after addition is placed on the fixing device, and then the slide 1 is placed under the fixing device. At this time, the first electric telescopic rod 13 is started. As the first electric telescopic rod 13 is started, the output end of the first electric telescopic rod 13 drives the slider 12 to slide inside the slide 1. At this time, the sliding slider 12 drives the connecting plate 14 to move. At this time, the first motor 19 is started. As the first motor 19 is started, the output end of the first motor 19 rotates. At this time, as the output end of the first motor 19 rotates, the first rotating rod 110 is driven to rotate. At this time, the rotation of the first rotating rod 110 drives the gear 111 to rotate. At the same time, the rotation of the gear 111 drives the track 112 to rotate synchronously. At this time, the rotating The crawler 112 will drive the sandpaper 113 to rotate synchronously. At this time, the sandpaper 113 is located below the bumper. At this time, the second electric telescopic rod 18 is started. As the second electric telescopic rod 18 is started, the rotating sandpaper 113 will gradually approach the bumper until the sandpaper 113 and the bumper are in contact. At this time, the bumper can be polished. At the same time, as the first electric telescopic rod 13 drives the slider 12 to move, the rotating sandpaper 113 can be driven to move. The second motor 26 is started. As the second motor 26 is started, the output end of the second motor 26 will rotate. At this time, the rotating output end will drive the second rotating rod 28 to rotate, and the multiple blades 27 will rotate synchronously with the rotation of the second rotating rod 28. The rotation of the multiple fan blades 27 will generate a certain amount of wind. At this time, a part of the wind will enter the interior of the air duct 22 through the ventilation holes 25. At the same time, the wind will continue to flow along the contour of the air duct 22 until it flows to the middle of the air outlet 23. Then the wind will flow out from the end of the air outlet 23, and then spray to the top of the frosted paper 113. As the wind enters the interior of the air duct 22, it is then sprayed out through multiple air outlets 23, which can reduce the accumulation of debris on the top of the frosted paper 113. At this time, by connecting the conical cylinder 3 in the middle of the multiple air outlets 23, the wind can be blown out following the guidance of the conical cylinder 3, thereby increasing the wind blowing surface. At the same time, by installing the second dustproof plate 31, it can reduce the debris from entering the interior of the air duct 22 through the end of the conical cylinder 3, thereby causing the air duct 22 to be blocked. In order to prevent the blockage from occurring and to blow dust off the top of the sandpaper 113, it is necessary to set the air duct 22 at a designated position. At this time, as the second motor 26 is started, the air duct 22 will shake to a certain extent. As time goes by, the air duct 22 will become loose. At this time, a fixing ring 4 is sleeved on the middle part of the air duct 22, and then the fixing ring 4 is connected to the top of the slide 1 through a connecting rod 41. At this time, the air duct 22 can be fixed at a designated position, i.e., above the slide 1. The sandpaper 113 will produce debris when grinding the bumper. At this time, the debris will float with the rotation of the fan blades 27. At this time, the floating debris will enter the interior of the slide 1. At this time, as the first electric telescopic rod 13 is started, the slider 12 will slide inside the slide 1.At this time, the block 51 is installed inside the card slot 5.
