ABSTRACT:
Locking pliers include a stationary front jaw, a stationary handle, a movable front jaw, a movable handle, an adjusting screw rod, and a locking lever. The movable front jaw is moved toward the stationary front jaw to clamp an object therebetween when the movable handle and the stationary handle are forcefully brought together by an external force applied thereto. A releasing lever for unlocking the movable front jaw and the stationary front jaw has a flex wall body with a substantially flat central portion and two opposite curved side portions flaring curvedly and upwardly from the flat central portion. The flat central portion has a width larger than the diameter of the adjusting screw rod.
