摘要： A power tool includes a motor housing having a motor configured to rotate an output shaft about a drive axis and a gear housing defining a gear compartment. A pinion gear is supported by the gear housing that is coupled to the output shaft for rotation about the drive axis. A bevel gear is supported by the gear housing for rotation about a bevel axis and includes a geared portion that is meshingly engaged with the pinion gear. A crank pin extends from the same side of the bevel gear as the geared portion at a position offset from the bevel axis. An articulating housing is pivotably supported by the gear housing for pivotal movement about the bevel axis. A plunger member is supported by the articulating housing for reciprocating movement along a reciprocating axis. The plunger member includes a yoke end portion coupled to the crank pin.
