Abstract:
1. A locking tool comprising: a first arm supporting a first jaw; a second arm movable relative to the first arm between a first position and a second position; a second jaw movable between a locked position when the second arm is in the first position and an unlocked position when the second arm is in the second position; a link comprising a first stop and a second stop, the link being operatively connected to the first arm and to the second arm such that the link moves as the second arm moves between the first position and the second position; a locking mechanism for locking the second jaw in the locked position the locking mechanism comprising a catch pivotably mounted relative to the second arm and biased in a first direction by a spring and having a first lobe and a second lobe extending from the catch that are positioned to engage the link, the link moving the catch from a rest position toward an intermediate position as the second arm moves between the second position and the first position by a first movement of the second arm toward the first arm, the first lobe engaging the first stop on the link to lock the second jaw in the locked position when the catch is in the intermediate position; and the first lobe being configured to disengage from the first stop to unlock the second jaw by a second movement of the second arm toward the first arm where the second movement of the second arm toward the first arm moves the link allowing the catch to rotate in a second direction under a force exerted by the spring to move the first lobe out of engagement with the first stop.
