A lifting device includes two opposite parallel rings; and a bridge member interconnecting the rings, the bridge member comprising a through hole having a diameter greater than that of a threaded shank of a thumb screw. Threaded shank of the thumb screw is adapted to drive through the through hole into a threaded hole in a rear end of a stationary handle of a self-adjusting locking pliers to rotatably retain the lifting device. |
