<p>An adjustable locking pliers (102) comprising a stationary handle (110), a stationary jaw (108), an operating lever (124) and a movable jaw (114). The movable jaw is coupled by a jaw axis (120) which is selectively displaceable to alter the jaws' gripping capacity. The operating lever (124) is coupled to the movable jaw by a first pivot (126). The operating lever rear forms a movable handle (132). A spring (170) biases rotation of the movable jaw (114) about the jaw axis (130) away from the stationary jaw (108). An actuation rod (128) is coupled to the operating lever (124) by a second pivot (130) part way along the operating lever and coupled to the stationary handle by means of a third pivot (148). The actuation rod (128) and the operating lever (124) are prevented from passing beyond alignment of the first (126), second (130) and third (148) pivots during clamping.</p> |
