POWDER CHARGE OPERATED SETTING TOOL (APPARATUS)

摘要

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.
