A clamping jaw includes an unthreaded rod receiver and a swing nut assembly including a swing nut lever and threaded nut coupling integrated thereon. An adjustment knob includes an adjustment knob collar fixed onto a second end of the threaded rob opposite said shaft collar. An idle jaw includes an unthreaded shaft collar adapted to receive and fit over a second end of the threaded rod. The swing nut is operable to interface the threaded nut coupling with the threaded rod held within the unthreaded rod receiver of the clamping jaw and move along the threaded rod by rotation of the adjustment knob while the idle jaw mounted on said threaded rod between the clamping jaw and the adjustment knob remain stationary next to the adjustment knob. The clamping jaw is freely movable along the threaded rod by disengagement of the swing nut and then by rotation of the adjustment knob when the swing nut is engaged with the threaded rod.
