In recent years, the electric tool industry in the development of local at the same time, pay more attention to the development of the international market. Electric tools is a kind of commonly used in modern hardware industry hardware tools products, generally according to the field of electric tools are applied to classify different, mainly metal cutting electric power tools, grinding tools, assembly power tools and railway use power tools; And the commonly used hardware electric tools in daily life mainly include electric drill, electric grinder, electric wrench and electric screwdriver, electric hammer and impact drill, concrete vibrator, planer, etc. , and general use of the different types of hardware electric tools field is also each are not identical. , drill, the main specifications are,,,,,,,,,,,,, mm, number refers to the tensile strength of N/mm steel drill bit diameter. For non-ferrous metals, plastic materials such as hole diameter than the original specifications largest ~ %. , electric grinder: use a grinding wheel or mill for grinding tool. There are straight to electric grinder and electric Angle grinder. , electric wrench and electric screwdriver: used for loading and unloading of threaded connection. Electric wrench transmission mechanism composed of planetary gear and ball screw groove impact mechanism. Specification is M, M, M, M, M, M, etc. Electric screwdriver with jaw clutch transmission mechanism or gear transmission mechanism, the specification is M, M, M, M, M, etc. , electric hammer and impact electric drill: used in concrete and brick walls and building component on the borehole, notching, MAO. Used in combination with expansion bolts, speed up the installation of pipeline, machine tool equipment and quality. , concrete vibrator, used for casting concrete foundation and compacted concrete reinforced concrete members, in order to eliminate porosity, increase the intensity. Including electric straight association-like vibrator of high-frequency disturbing force by the motor drive the eccentric block and form, motor by Hz or Hz medium frequency power supply. , planer: used for cutting wood or wood pieces, in also can be used for small bench plane on the bench. Planer knives shaft driven by the motor shaft by the belt.
