Electric impact wrenches (Electric Impact Wrench or Electric Torque Wrench) are power tools driven by electric motors that output high torque through impact mechanisms. They are widely used in automotive repair, construction, assembly manufacturing, and other scenarios for tightening or loosening bolts, nuts, and other fasteners. 1. Working Principle of Electric WrenchesElectric wrenches utilize a motor to drive an internal hammering mechanism (impact mechanism), applying intense impact force repeatedly within a short time to quickly loosen or tighten bolts. This method is much more efficient than manual tools, especially suitable for dealing with rusted fasteners or high torque requirements.
