Rotatable within the crescent-shaped head portion is a jaw member that is rotatable within the crescent-shaped head portion, the jaw member being rotatable about an axis which passes through the crescent-shaped head portion. A spring biased ratchet member is displaceable in a direction parallel to the axis of rotation of the jaw member and is configured to engage and disengage the jaw member to either limit rotation of the jaw member in one direction and one direction only and in a release position to allow the jaw member to rotate freely in either direction.
