摘要： The present disclosure discloses an electronic device and a rotating shaft mechanism thereof, and relates to the field of mechanical technologies. A first fixing assembly and a second fixing assembly in the rotating shaft mechanism are connected to each other by a first connector and a second connector. A hollow region can be reserved in the rotating shaft mechanism as the first connector and the second connector may be shorter. Thus, an external circuit of the electronic device can pass through the hollow region and be disposed in a second body of the electronic device. The second body can protect the external circuit to avoid damages to the external circuit, such that reliability of the electronic device is higher. In addition, since the external circuit is disposed in the second body of the electronic device, aesthetics of the electronic device is better.
