Abstract
A locking pliers wrench adjustable to grip between two jaws and lock onto objects in a range of sizes. An elongated handle forms the body of the wrench. The rear portion of the handle is channel-shaped in cross section and houses a gripping size adjusting screw and a jaw actuating slider actuated thereby. One jaw is rigidly mounted on the fore end of the handle while the second jaw is pivotally mounted on the handle at a first point adjacent the rear end of the first jaw. A second handle extends generally parallel to the body forming first handle and is pivotally connected to the second jaw at a second pivot point spaced from the first pivot point. A link connects the second handle with the fore end of the jaw actuating slider. The adjusting screw is free to rotate but is restrained from axial movement. A nut is locked in the rear end of the slider so as to receive the threaded shank of the screw. The rear portion of the screw rotatably engages the rear end of the body forming handle. Rotation of the screw shifts the slider in opposite directions in the body forming handle and in turn adjusts the size of the gripping opening between the two jaws.
