Abstract
A quick release saw blade chuck for connecting a free end of a saw blade to a reciprocating arm of a saw includes a blade holder including a first surface. The free end of the saw blade is interposed between the first surface and the inner surface of a clamping member. The clamping member is coupled to the blade holder by an attachment mechanism which defines a blade-accepting space and a second space between the first and inner surfaces. A mechanism is also provided for varying the size of second space and thereby pivoting the clamping member about the attachment mechanism to vary the size of the blade-accepting space and clamp a blade inserted therein.
