ABSTRACT:
A riveting tool of simple design adapted for repeated one side riveting of rivet nuts particularly in mass production and also suitable for use with a reversible motor drive is provided with a single-threaded pull mandrel and a dolly with an opening corresponding to the external cross section of the threaded pull mandrel. The dolly is slidably arranged on the mandrel. A claw clutch having an upper and a lower part is arranged so that the upper surface of the body of the dolly contacts the lower part of the claw clutch. A retaining element with an opening corresponding to the external cross section of the threaded pull mandrel is freely turnable on the mandrel and the lower part of the retaining element contacts the upper part of the claw clutch for engagement with the lower part of the clutch. A tightening nut is screwed on the upper part of said mandrel. In another embodiment of the invention, an adjustable stop is fixed on the threaded pull mandrel above the tightening nut.
