Abstract
A reciprocating saw is provided having a motor oriented within a housing for operably driving a saw bar and blade holder in a reciprocating motion. The blade holder has a longitudinal slot for receiving a saw blade, and a transverse aperture extending into the longitudinal slot for receiving a follower. A sleeve is pivotally mounted upon the body, and has a circum-axial cam groove formed therein cooperating with the follower. Rotation in a first lock direction urges the follower into the longitudinal slot for engaging the saw blade and rotation of the sleeve in a second unlock direction allows the follower to retract. A biasing member is included for biasing the sleeve in the first lock direction. The sleeve central bore is adapted to provide clearance for the follower such that the sleeve is permitted to axially translate relative to the body for assembly or disassembly of the blade holder.
