Abstract
Locking pliers including fixed unit of generally elongate shape which forms at one end a fixed handle and at the other end a fixed jaw. A movable unit includes a movable jaw articulated to the fixed jaw, and an actuating lever of which one end is articulated to the movable jaw and the other end forms a movable handle. Also, a toggle mechanism is provided and includes a link articulated to an intermediate point of the lever and extending to a rear bearing point adjustable along the length of the fixed handle. The actuating lever crosses a straight line which joins the articulation of the movable jaw to the bearing point of the link, and the fixed handle extends substantially along a straight line joining the articulation to the bearing point.
