Riveting device having a compact design

A riveting device (1), comprising:

• a device housing (5);
• a riveting tool (10) having
• a mouthpiece (11) and
• a mandrel holder (12),
• wherein the mandrel holder (12) can be moved relative to the mouthpiece (11) along an operative axis (w);
• and
• a drive device (30) in the device housing (5) for actuating the riveting tool (10) with a threaded spindle (33),
• wherein the threaded spindle (33) has a feed thread (33.3),
• wherein the threaded spindle (33) is operatively connected to the mandrel holder (12) and is configured to be moved along the operative axis (W),
• wherein the threaded spindle (33) is formed as a hollow spindle having a through hole (40) extending in a direction of its longitudinal extension,
• wherein the threaded spindle (33) is coupled to a torque arm (41),
• wherein the torque arm (41) secures the threaded spindle (33) against rotation relative to the device housing (5), and
• wherein the torque arm (41) is fixed on the threaded spindle (33) via the through hole (40).
