Abstract
A saw blade clamping arrangement for a power tool including a drive shaft and a saw blade releasably interconnected with the drive shaft for reciprocating motion along a longitudinal axis. The saw blade clamping arrangement includes a support mechanism interconnected with the drive shaft, the support mechanism configured to selectively receive the saw blade in first and second orientations, an actuator mounted on the drive shaft and rotatable relatively to the drive shaft between an engaged position and a disengaged position, the actuator including first and second locking cam surfaces, and first and second locking members operatively associated with the actuator, and movable between a locked position that selectively locks the blade to the corresponding first and second orientations and an unlocked position that releases the blade. The first and second locking members including first and second follower surfaces driven by the respective first and second locking cam surfaces.
