Abstract
A blind rivet fastening device including a dual function clutch device. The clutch releases at the rear end position RP of the pulling head and the clutch slips at the home position HP. The device includes a spindle clutch axially movable with respect to the spindle and integrally rotated, and a nut clutch integrally formed with the ball screw nut. The spindle clutch can move in the axial direction and can release from the nut clutch. The spindle clutch also has a first segment portion; one end of the first segment portion is a vertical plane and the other end is a slanted plane. The nut clutch has second segment portions of complementary shape. When the pulling head reaches the rear end position RP, the clutch is disengaged. When the pulling head returns to the home position HP, the inclined faces of the clutch slip with each other.
