ABSTRACT:
A pair of locking pliers includes a body having a fixed jaw that supports a fixed extension. A movable jaw is pivotably mounted to the body by a hinge pin, and the movable jaw includes a movable extension. An operating lever is pivotably mounted to the movable jaw to close the movable jaw, and the movable jaw is shaped such that the movable extension slides along the fixed extension as the movable jaw is pivoted closed with the operating lever in order to provide an axial clamping action.
