A tool for use on a generally tubular workpiece includes a clamp base having an opening, a first jaw coupled to the clamp base with a first linkage and a second jaw coupled to the clamp base with a second linkage, a translation mechanism disposed on or within the clamp base operatively coupled to the first and second jaws via one or more adjusting links, whereby the first and second jaws are adapted to move, under a force communicated by the adjusting links and the linkages, within the opening between an open position in which the respective bottom ends of the first and second jaws are spaced apart to a closed position in which the respective bottom ends of the first and second jaws are abutting. |
