A jigsaw drive shaft is connected to a blade by the blade clamp of the present invention. The blade clamp comprises a clamp body mounted securely to the drive shaft by a bracket. The clamp body has a hollow portion formed to receive an upper portion the jigsaw blade. The clamp body also includes a hollow tubular extension. A cam body is pivotable about an axis through a cylindrical bore such that cam surfaces move in and out of contact with an interior surface of the clamp body to engage or release the blade. A spring biases the cam body into engagement with the clamp body surface. The user must press on a protrusion of the cam body to pivot the cam surfaces way from the clamp surface and against the force of the spring.

Blade clamp for reciprocating saw

The present invention provides a plunge-cut action circular saw having a double pivot hinge mechanism. Problems associated with this hinge mechanism, in particular axial end flow are reduced by urging a component of the hinge against a fixed component of the saw, such as a base plate component or the like. The urging force is applied by a resilient member, such as a spring washer.
