    摘要： The invention relates to a reciprocating saw that includes a reciprocatable spindle for supporting a saw blade for reciprocating sawing movement. A body houses a motor and a drive mechanism driven by the motor. The drive mechanism selectively drives the spindle and the body supports the spindle. A grip extends outwardly from the body adjacent a center of gravity of the saw so as to allow an operator to operate the reciprocating saw with a first hand and support a workpiece being cut with a second hand.

    摘要： A drive mechanism for a power tool, a power tool and a reciprocating saw. The power tool includes a housing, a motor supported by the housing and including a drive shaft, an output member supported by the housing and adapted to support a tool element, and a drive mechanism. The drive mechanism includes a drive assembly driven by the drive shaft for rotation about an axis, the drive assembly including a gear, a hub selectively driven by the gear for rotation about the axis, and structure positioned between the gear and the hub, the structure selectively transmitting drive force between the gear and the hub and selectively allows relative movement between the gear and the hub. The drive mechanism may also include a drive arm drivingly connected between the drive assembly and the output member of a tool, and the drive arm may be configured to absorb an impact.
