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.
