초록

This invention relates to an electric impact tool characterized by a pair of electric motor-driven counterrotating flywheels, at least one of which is movable relative to the other from a retracted inoperative position into an extended operative one closely adjacent the other flywheel whereby a ram is squeezed therebetween and impelled forward at high speed against a workpiece. The nosepiece of the tool frame is retractable although normally extended due to the spring bias urging it and the movable flywheel to which it is mechanically linked into disenga...
