ABSTRACT:
A fastening element setting tool includes a housing (1), an axially displaceable guide sleeve (2) located within the housing, a bolt guide (3) extending forwardly from the guide sleeve, and a receiving sleeve (4) partially laterally enclosing and axially displaceable relative to the bolt guide (3). The receiving sleeve (4) and the bolt guide (3) are telescopically displaceable relative to one another by an amount in the range of 3 to 5 times the outside diameter of the bolt guide. A protective sleeve (5) at least partially laterally encloses and is axially displaceable relative to the receiving sleeve (4). In the course of its axial displacement relative to the receiving sleeve (4), the protective sleeve (5) strikes against a leading end face (1a) of the housing (1) and prevents the full displacement of the guide sleeve (2) into a position ready for ignition of the tool.
