Patent ID: 8485071

Claim:
A self-clamping wrench comprising: a handle having an elongated member defining a proximal end and a distal end, the handle defining a top side and a bottom side, also defining a cavity integrally formed with the elongated member at said distal end and extending away from the top side, the handle having: a first pivot at the distal end; a second pivot also at the distal end; a spring-loaded latch pivotal within the cavity and pivotally connected to the second pivot, wherein one end of the spring-loaded latch extends toward the top side from the second pivot and another end forms a bottom lever, the latch being movable about the second pivot from an unlocked position to a locked position by pivoting toward the proximal end; a first clamping jaw having a first end pivotally connected to the handle at the first pivot and having a second end that includes a third pivot; and a second clamping jaw pivotally connected to the first clamping jaw via the third pivot to constitute with the first clamping jaw an articulated clamping jaw, the second clamping jaw having a free end for displacing the spring-loaded latch from the unlocked position to the locked position, the latch locking the free end of the second clamping jaw when the free end of the second clamping jaw has pushed past the latch, wherein the spring-loaded latch is actuated by a push-button release mechanism that extends within the handle for disengaging the second clamping jaw from the latch, wherein the spring-loaded latch is actuated by a push-button release mechanism that extends within the handle proximate the spring-loaded latch for disengaging the second clamping jaw from the latch.
