ABSTRACT:
An explosive powder charge operated setting tool includes a housing containing an axially extending fastening element guide which is axially displaceable opposite to the driving direction when the front end of the setting tool is pressed against a structural component into which a fastening element is to be driven. When it is axially displaced, the fastening element guide displaces a piston guide which, in turn, means a device into a cocked position so that a firing pin in the device is ready to ignite the powder charge. The fastening element guide has an axially extending feed slot aligned with a magazine forming a part of the housing. Fastening elements are connected together in a belt-like fashion by guide bushes each positioned on a fastening element. The feed slot has a stepped width extending in the axial direction so that in axial displacement of the fastening elements only a single fastening element can be positioned to be driven from the fastening element guide.
