  • Patent number: 7389714
    Abstract: A locking pliers tool with an improved dual action driver handle comprising two intersecting handles and interacting jaws. When the user grips the handle forward the resultant force produces a locking action. Conversely, when a rearward gripping force is initiated, the tool releases its grip on the object. A limited amount of energy on the inventive handle produces free movement of the handle and gripping mechanism to lock or release. The system operates with a handle and stationary jaw in conjunction with a second pivotally secured jaw and internal adjustment bolt. A second lever handle rests against the adjustment bolt. An over center toggle link connects the second lever handle to the pivotally secured second jaw. A tension spring interconnects the first handle and the pivotally secured second jaw.
