초록

A powered hammer includes a housing, a tool holder coupled to the housing and configured to hold a tool, a motor within the housing, and a piston slideably mounted within the housing. A drive mechanism converts rotary output of the motor into a reciprocating motion of the piston. A ram is slideably mounted within the housing, forward of the piston, and is reciprocatingly driven by the piston. A beat piece is slideably mounted forward of the ram. The beat piece is repetitively struck by the reciprocating ram, which in turn repetitively strikes an end of t...
