ABSTRACT:
An adjusting device for a tool includes a body with two ends and a fluid filled passageway, which extends between the ends, one end of the body cooperates with a work piece. An actuating member is movably connected to one end of the body, communicates with the fluid in the passageway, and has a surface, which cooperates with the work piece. Another actuating member is movably connected to the other end of the body and communicates with the fluid, and moves the fluid against the first actuating member to extend it. The fluid is locked against the first actuating member so that it retains the work piece in the body end.
