Abstract
A toolless blade clamp for a reciprocating saw is disclosed comprised of a clamp body that defines a cavity for receiving a saw blade, a wedging member that traverses the cavity, operating means that is coupled with the wedging member and biasing means that acts on the operating means. In a clamping position, the operating means urges the wedging member into contact with an edge of a saw blade to securely clamp it within the cavity. In a releasing position, the operating means is manually urged by the user to bring the wedging member free of the cavity to allow insertion or removal of the saw blade.
Claims14
A blade clamp for a reciprocating tool comprising
- a clamp body that defines a cavity for receiving a mounting portion of a saw blade, said cavity partially defined by a longitudinal face extending substantially parallel to an intended direction of reciprocation of said clamp body and an inclined surface that is slanted with respect to and opposite said longitudinal face;
- a wedging member that traverses said cavity and is movable along said inclined surface;
- operating means that is disposed about at least a portion of and movable with respect to said clamp body and physically coupled with said wedging member for urging the wedging member into a releasing position to allow a saw blade to be inserted into or removed from said cavity;
- and
- biasing means for urging said operating means into a clamping position which brings said wedging member into a clamping engagement with a saw blade inserted into said cavity.
A reciprocating tool comprising
- a driving member;
- a blade clamp configured at the end of said drive member;
- said blade clamp comprising
- a clamp body that defines a cavity for receiving a mounting portion of a saw blade, said cavity partially defined by a longitudinal face extending substantially parallel to an intended direction of reciprocation of said clamp body and an inclined surface that is slanted with respect to and opposite said longitudinal face;
- a wedging member that traverses said cavity and is movable along said inclined surface;
- operating means that is disposed about at least a portion of and movable with respect to said clamp body and physically coupled with said wedging member for urging the wedging member into a releasing position to allow a saw blade to be inserted into or removed from said cavity;
- and
- biasing means for urging said operating means into a clamping position which brings said wedging member into a clamping engagement with a saw blade inserted into said cavity.
