ABSTRACT:
A powder charge operated setting tool includes a barrel (5) and a closing or breech member (8), both axially displaceable in a housing (1). Tensioning of a tension spring (18) for a firing pin (17) is made possible by means of a disengageable snap-in element (12) acting between housing (1) and closing member (8) by pressing the barrel (5) against the receiving material. The disengagement of the snap-in element (12) occurs only by overcoming a predetermined force acting counter to the setting direction which is generated by the gas pressure after a propellant charge (19) has been ignited.
