A circular carrier for an adjusting ring can be positioned so that the movable jaw operates against faces on the end or side of the wrench frame. The main part of the frame is comprised of side plates with open space between them to allow for movement of the tail portion of the movable jaw. A spring connecting the carrier and frame moves the jaws toward their gripping position.
