Power tools convert electrical energy into mechanical energy through the motor system and electronic control system, which can multiply people's work efficiency and have the advantages of zero emission, low noise, low vibration, and portability. Compared with manual tools, it is more efficient and professional; With pneumatic tools, it does not require heavy air compressors, making it more portable and less noisy; With gasoline-powered tools, it can effectively reduce carbon emissions and actively help carbon peak index.
