ABSTRACT:
Disclosed is a new and improved device for gripping and rotating a workpiece. The device includes an adjustable jaw, adjustable through a rack and pinion gear assembly so that torque applied to the gear member, for example by connecting the gear to a cooperatively fitting ratchet wrench drive handle, causes simultaneous jaw tightening and rotation of the device to achieve rotation of the workpiece without jaw slippage.
