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.

A hand truck assembly includes a frame including an upper portion and a lower portion. The assembly further includes a handle attached to the upper portion of the frame. The assembly also includes a pair of wheels attached to the lower portion of the frame. In addition, the assembly includes a fixed work support member attached in fixed relation to the lower portion of the frame. The assembly further includes a movable work support member attached to the lower portion of the frame, the movable work support member being moveable between (i) a first position in which a free end portion of the movable work support member rests on the fixed work support member, and (ii) a second position in which the free end portion of the movable work support member is spaced apart from the fixed work support member. The assembly also includes a post attached in fixed relation to the free end portion of the movable work support member. The assembly additionally includes a power tool such as a hammer jack that defines a cavity. When the movable work support member is positioned in the first position, (i) the post is located within the cavity of the power tool, and (ii) the power tool is supported on the movable work support member.

A tool support structure with an adjustable work support assembly comprises a base and a horizontal support provided on the top of the base. A work support assembly is provided on the horizontal support and is linearly slideable in a vertical direction in relation to the horizontal support. The work support assembly includes a first component and a second component. The first component is configured to be fixed in one of a plurality of first vertical positions with respect to the horizontal support. The second component is also provided on the horizontal support and is linearly slideable in a vertical direction in relation to the first component. The second component is configured to be fixed in one of a plurality of second vertical positions with respect to the first component.
