The movable jaw has a loop on the back; a lever handle with a fulcrum point hooks into that loop. In use, pressure on the fulcrum handle is relaxed allowing the movable jaw to be adjusted. When the handles are squeezed together the movable jaw is bound against the main bar to hold adjustment. A separate sliding loop can hold this adjustment.
