Abstract
A reciprocating tool that includes a spindle that reciprocates with respect to a housing within a cavity of the housing. The reciprocating tool includes a blade clamp mechanism actuator coupled to the housing for movement with respect the housing between first and second positions. The spindle reciprocates with respect to the blade clamp mechanism actuator. A blade clamp mechanism is coupled to the spindle for reciprocating movement therewith, and the blade clamp mechanism is configured to attach the saw blade to the spindle. The blade clamp mechanism includes a collar mounted on the end of the spindle, and the collar is rotatable about the longitudinal axis of the spindle between an engaged position and a disengaged position in response to movement of the blade clamp mechanism actuator between the first position and the second position.
