Blind rivet nut setting device

A blind rivet nut setting device comprising:

• a drawing mandrel;
• a motor;
• a first drive line being disposed between said motor and said drawing mandrel, said first drive line having means for selectively producing a rotational movement of said drawing mandrel, said first drive line including a rotational direction dependent slip coupling that includes a coil spring, said first drive line including a selectively connectable rotation coupling;
• a second drive line being disposed between said motor and said drawing mandrel, said second drive line having means for producing an axial movement of said drawing mandrel, said second drive line including a drive element and an output element, said drive element being axially movable for a predetermined length that includes an idle stroke length and an effective stroke length where an end position of said axial movement of said drive element is predetermined, so that said effective stroke length ends immediately when said drive element reaches said end position, said idle stroke length being adjustable.
