  • Pliers having greater holding force
    Patent number: 7546784
    Abstract: A pair of pliers include a shank, a fixed jaw locked onto the shank, and a movable jaw pivotally mounted on the shank and movable relative to the fixed jaw. Thus, the first contact point of the locking teeth of the fixed jaw and the second contact point of the first engaging teeth of the first toothed face of the movable jaw have a larger friction with a workpiece by a special angle design of the fixed jaw and the movable jaw to enhance the clamping force of the fixed jaw and the movable jaw on the workpiece, so that the workpiece is clamped by the fixed jaw and the movable jaw exactly and closely to prevent the workpiece from being slipped from the fixed jaw and the movable jaw during operation of the pliers.
