A nut is in operative communication with the drive shaft so thatthe drive shaft rotationally drives the nut. The nut threads engage thejaw threads so that rotation of the nut moves the jaws axially within thepassageways. A sleeve is selectively actuatable to a first axial positionand a second axial position.
