Patent ID: 8479615

Claim:
A wrench comprising: an L-shaped handle having an elongated member defining a proximal end and a distal end, the handle defining a top side and a bottom side, also having a short downward extension 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 on the short downward extension of the L-shaped handle; a spring-loaded latch pivotal within the cavity and pivotally connected to the second pivot and extending toward the top side from the second pivot, the latch being movable about the second pivot from an unlocked position to a locked position by pivoting toward the proximal end; a pin attached to the latch, the pin slides within a guide groove formed on the short downward extension to limit rotational motion of the latch; 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.
