Abstract
A saw blade clamping arrangement for a power tool including a housing, a drive shaft mounted for reciprocating motion relative to the housing and having a longitudinal drive axis, and a saw blade releasably interconnected with the drive shaft. The saw blade clamping arrangement includes a blade support mechanism with first and second slots crosswise intersecting slots configured to selectively receive the saw blade in first and second orientations. The clamping arrangement also includes a tubular actuator rotatable about the longitudinal drive axis between an engaged position and a disengaged position, the actuator including a locking cam surface, and a locking member operatively associated with the actuator, and movable between a locked position that selectively locks the blade in one of the first and second orientations and an unlocked position that releases the blade, the locking member including a follower surface driven by the locking cam surface.
