Abstract
A fastener installation tool including an upper jaw having a head adapted to engage a fastener for securing a plurality of workpieces to one another, a lower jaw, and first and second pairs of links fastened to the upper and lower jaws. The tool includes a hydraulic cylinder having one end attached to the lower jaw and a piston rod attached to the first pair of links. The cylinder actuates the tool between a disengaged position, in which the links are in a retracted position and the upper jaw and the lower jaw are juxtaposed with one another, and an engaged position, in which the links are in an extended position and the upper jaw and the lower jaw are spaced apart from one another. The tool is adapted to install the fastener to the workpieces when the tool is in its engaged position.
