A power operated blind-rivet setting tool comprises a hand-piece which carries a rivet pulling plunger and a piston in a cylinder furnished with a trigger operable valve for admission of working fluid to one or other end of the cylinder. A piston rod joined by one end to said piston has its other end operatively connected to the plunger, and a compression spring sleeved on said piston rod is so arranged as to store energy during a non-working stroke of said piston and to release that energy during a working stroke of the piston. |
