A riveting device has a device housing, a riveting tool and a drive for actuating the riveting tool. The riveting tool has a mouthpiece and a mandrel holder that can be moved relative to the mouthpiece along an operative axis. The drive has a spindle gear with a threaded spindle, and a spindle nut operatively connected thereto. The threaded spindle is operatively connected to the mandrel holder for movement along the operative axis. A support structure provides axial support of the spindle nut. A tool housing is axially supported on the mouthpiece and axially supported on the support structure via a flange. The mandrel holder is received axially moveably in the tool housing. A supporting structure supports the tool housing. The tool housing is held on the supporting structure by a retaining structure. The retaining structure and the supporting structure are connected to each other via a bayonet lock.

An electro-hydraulic riveting tool has a riveting working head and a pump body. The riveting head consists of a cylinder block, a hollow piston shaft, and a rear end cover. The cylinder block and the rear end cover jointly define a hydraulic cavity. Inside the cylinder body, a first oil passage and a second oil passage are formed. On the pump body, a third oil passage and a fourth oil passage are provided. A broken-nail guide tube is coupled to the riveting working head. The rear end of the broken-nail guide tube is in communication with a nail-collecting box. An adapter plate is sleeved around the outer wall of the broken-nail guide tube. The adapter plate contains an intermediate oil passage with a first and a second intermediate oil passage. An accommodation groove is formed in the adapter plate, and a shock-absorbing joint is housed within this groove.
