ABSTRACT:
A device for gripping a cylindrical pin. The gripping device has a pair of gripping jaws and a pair of angled levers. The gripping jaws each have interior surfaces disposed in opposing relation and defining a space between the interior surfaces to receive and engage a cylindrical pin. The angled levers each carry one of the gripping jaws near the end of the lever, the levers being further disposed to pivot in angular relation so as to vary the space between the interior surfaces of the gripping jaws and thus grip cylindrical pins of varying sizes. A lock is disposed to cooperate with the angled levers for biasing the angled levers toward each other to engage the cylindrical pin. A handle is attached to the levers for applying a force to the levers and thus to the cylindrical pin engaged by the gripping jaws, the force being directed substantially axially to the cylindrical pin.
