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 perpendicular to the drive axis, the bevel gear being meshingly engaged with the pinion gear. A crank pin extends from the bevel gear 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. The reciprocating axis and the drive axis reside in the same plane throughout pivotal movement of the articulating housing with respect to the gear housing.
