According to the "Forecast of Production and Sales Demand and Analysis Report on Transformation and Upgrading of China's Electric Tool Industry", various types of electric tools are mainly divided into metal cutting electric tools, grinding electric tools, assembly electric tools, and railway electric tools. Common electric tools include electric drills, electric grinders, electric wrenches and screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers&Nbsp; The main specifications of electric drills include 4, 6, 8, 10, 13, 16, 19, 23, 25, 32, 38, 49mm, etc. The numbers refer to the maximum diameter of the drill bit drilled on steel with a tensile strength of 390N/mm. The maximum drilling diameter for materials such as non-ferrous metals and plastics can be 30-50% larger than the original specification, equipped with a polishing machine&Nbsp; Electric wrenches and screwdrivers are used for loading and unloading threaded connections. The transmission mechanism of an electric wrench consists of a planetary gear and a ball spiral groove impact mechanism. The specifications include M8, M12, M16, M20, M24, M30, etc. The electric screwdriver adopts a tooth embedded clutch transmission mechanism or a gear transmission mechanism, with specifications such as M1, M2, M3, M4, M6, etc&Nbsp; Electric hammers and impact drills are used for drilling, grooving, and roughening in concrete, brick walls, and building components. By using expansion bolts, the installation speed and quality of various pipelines and machine tools can be improved; The impact principle of an electric hammer is to generate impact power through internal piston movement, while the impact principle of an impact drill is to generate impact power through gear running in, so the impact force of the electric hammer is greater&Nbsp; Concrete vibrators are used to compact concrete when pouring concrete foundations and reinforced concrete components to eliminate air holes and improve strength. The high-frequency disturbance force of the electric direct connected vibrator is formed by the motor driving the eccentric block to rotate, and the motor is powered by a 150Hz or 200Hz intermediate frequency power supply. [1] Electric planer is used for planing wood or wooden structural components, and can also be used as a small planer when installed on a platform. The cutter shaft of the electric planer is driven by an electric motor shaft through a belt&Nbsp; Electric grinding, commonly known as grinding head machine; Electric grinding; Electric grinding machine, an electric tool used for grinding with a grinding wheel or disc&Nbsp
