ABSTRACT:
Apparatus is provided which couples to one jaw of a pair of jaws of an expandable jaw power tool to remotely apply and distribute expansion power of the pair of power jaws when the jaws are actuated. A sleeve or collar is fitted over one of the jaws of the pair of power jaws, the sleeve adapted to receive and support one end of a threaded shaft, the other end of which supports a power or pressure distributing member. The threaded shaft screw-couples into a tapped hole in the sleeve and impinges upon one side of the jaw over which the sleeve is fitted, locking the sleeve on to the jaw. Thrust or expansion power, normally applied between the two jaws upon expansion, is applied between one jaw and the remote power or pressure distributing member coupled to the locked sleeve.
