Abstract: A locking pliers comprises a fixed assembly comprising a first handle and a first jaw. A second jaw is movable relative to the first jaw. A second handle moves relative to the first handle to move the second jaw. A toggle-link locking mechanism locks the second jaw in the closed, locked position. An adjusting screw is provided for adjusting the geometry of the locking mechanism to thereby adjust the jaw spacing and the force exerted by the jaws is provided. The adjusting screw includes a wheel that can be rotated by running the wheel along an object. In another embodiment the adjusting screw includes a sleeve that extends partially over the fixed assembly such that it can be manipulated by the same hand that holds the locking pliers.

Abstract: A pair of pliers has a tool mounted to each arm end, such as, for example, a screwdriver tip at one end of each handle, a nail puller in the jaws of the pliers and a spring-loaded, slip joint-activated locking mechanism to hold the jaws in a predetermined position by operation of the slip joint, with an optional socket receiving tip on the pliers.

Abstract: A hand tool of the pliers type has a screwdriver tip at the end of each handle of the pliers with a locking device for locking the pliers in open position to provide a handle for the screwdriver from the other arm of the pliers, while providing a nail pulling capability.

Abstract: A pair of pliers is equipped with an expander unit that spreads the handles so that the jaws will forcibly grip objects from the inside. External teeth on the jaws aid in gripping.
