[0002] In the Chinese patent announcement number CN101200054B, the announcement date was June 23, 2010, and the name is a manual grinding and dust removal device. , the front and rear of the sandpaper holder bottom plate of the manual grinding and dust removal device are provided with sandpaper installation grooves that are connected to the bottom surface, so that the air duct inside the sandpaper holder bottom plate can only be limited by the sandpaper installation grooves and extend through the narrow space on both sides. To the air intake device at both ends of the front and back of the bottom of the sandpaper holder bottom plate, therefore, the suction force (brought by the motor of the dust suction device) at both ends of the air intake device arranged around the soft body on the bottom surface of the sandpaper holder bottom plate will be affected

At present, the walls and roofs of our living rooms are not very smooth after batch scraping, and there are inevitably some recesses, and the tools used to polish the walls and tops of the living rooms are not very smooth with the walls and tops.
