摘要：
An improvement in a gripping tool having a grip surface carried by movable grip elements and cam linkages to radially move the grip surface from a retracted to an extended position. The improvement involves a tri-cam linkage with cam pairs supporting bi-rotary to axial stroke activation and further cam linkages to cause radial stroke of the tool grip surface as a function of axial stroke.
