It can not only beautify the environment, but also save a lot of wood. This move has achieved good social, economic, and technical effects. Doors and windows are divided into enclosure components or partition components according to their location. Polishing refers to grinding or rubbing the surface of objects to make them smooth and delicate. Its function is to remove burrs, floating rust, oil stains, and dust on the surface of the substrate, and to remove coarse particles and impurities on the surface of the coating to obtain a flat surface. The smooth coating surface should be polished to a certain degree of roughness to enhance the adhesion of the coating. The polishing area and depth depend on the degree of damage. According to regulations, it should be polished until there are no signs of damage and aging cracks.

When the sanding disc 3 needs to be replaced, pull the sliding limit tube 9 by hand. When the end of the sliding limit tube 9 away from the elastic spring 8 is located at the position corresponding to the limit ball 10, the shape of the end of the sliding limit tube 9 away from the elastic spring 8 can also limit the limit ball 10 to prevent the limit ball 10 from being separated from the abutment groove 11.

When the connecting wire 4 needs to be recovered, the pulling rod 21 is pulled, and the pulling rod 21 drives the second clamping tooth 23 to disengage from the first clamping tooth 20 through the first elastic telescopic tube 22. The force storage torsion spring 18 will drive the rotating round block 28 and the recovery wheel 16 to reset and rotate through the clamping arc block 19, and the recovery wheel 16 will recover the connecting wire 4.
