[0002] Building decoration is a process of treating the internal and external surfaces and spaces of a building with decorative materials or ornaments to protect the main structure of the building, improve the function of the building and beautify the building. In building decoration projects, angle grinding equipment is a commonly used equipment. The common angle grinding equipment in the prior art is an angle grinder, which is mainly used for cutting and grinding. Its main structure is roughly composed of a motor and a cutting blade and other parts. When in use, the cutting blade is fixed to the rotating shaft of the motor. When the motor rotates, it drives the cutting blade to rotate, thereby achieving grinding and cutting.
