Setting tool

A setting tool, comprising a housing (1);

• a bolt guide (2) secured in the housing (1) against displacement in an axial direction and having a radial, flange-shaped shoulder (3) having a stop surface (4) facing in a setting direction;
• a press-on feeler (6);
• a spring (13) for biasing the press-on feeler (6) in the setting direction;
• and an axially displaceable safety sleeve (9) surrounding the press-on feeler (6), the safety sleeve (9) having an entraining surface (17) facing in a direction opposite the setting direction and cooperating with a facing in setting direction, counter-surface of the press-on feeler (6) in a position of the safety sleeve (9) in which a facing in a direction opposite the setting direction, free end surface (14) thereof engages the stop surface (4) of the bolt guide (2),
• wherein a first distance (A1) between the setting direction-side, end surface (7) of the press-on feeler (6) and the counter-surface (18) thereof is greater than a second distance (A2) between a setting direction-side, end surface (10) and the entraining surface (17) of the safety sleeve (9), and
• wherein a sixth distance (A6) between the free-end surface (14) of the safety sleeve (9) and a setting direction side, end surface (10) of the safety sleeve (9) corresponds at most to a fifth distance (A5) between the end surface (5) of the bolt guide (2) and the stop surface (4) thereof.
