A quick release device for use with chain saws and which is adapted to quickly attach a bar and chain to the motor assembly of the chain saw. The quick release device comprises a body having an upper jaw and lower jaw. The jaws are adapted to engage notched ends of studs extending from a motor assembly and thereby clamp the bar and chain to the motor assembly. A rotatably threaded shaft cooperates with the body in a unique manner such that turning of the shaft in a manner which causes a clamping action actually biases the jaws away from one another. A head is located on the threaded shaft with a plurality of apertures so that one can readily engage an aperture with a tool thereby facilitating manipulation of the head.

A quick release device for attachment of a cutting assembly of a chain saw comprised of a chain saw bar and a cutting chain to a motor assembly of the chain saw and allowing an operator to rapidly detach the cutting assembly from the motor assembly of the chain saw, the chain saw having a motor housing and a plurality of studs wherein the studs engage both the bar and an outer side plate forming part of the motor assembly; said quick release device comprising: a) a clamping member having a pair of jaws which are movable relative to one another for simultaneously releasably engaging each of the studs and thereby clamping the bar and chain of the cutting assembly and the outer side plate to the motor assembly of the chain saw and thereby eliminating the necessity of nuts to hold the side plate and cutting assembly to the motor assembly; and b) a manually movable mechanism on said clamping member for rapidly tightening one of said jaws against the side plate wherein said quick release device does not otherwise interact with the side plate or the cutting assembly except to clamp the cutting assembly and side plate on the studs to the motor assembly, said manually movable mechanism also being adapted to release the clamping action provided by said clamping member to enable removal of the side plate and cutting assembly; wherein said clamping member comprises an upper jaw and a lower jaw, hinge means connecting said upper and lower jaws for allowing the upper jaw to move relative to the lower jaw so that at least one of the jaws can be moved relative to the other to an open jaw position and a closed jaw position.
