Rotating shaft body and electronic device

An electronic device, comprising a first housing and a second housing, wherein the first housing and/or the second housing is provided with a display screen, the first housing and the second housing are connected by a rotating shaft body the first housing is rotatable around a first rotating surface of the rotating shaft body, and the second housing is rotatable around a second rotating surface of the rotating shaft body;

• wherein the rotating shaft body comprises the first rotating surface and the second rotating surface, wherein the first rotating surface and the second rotating surface have a common side edge, an axis of rotation of the first rotating surface and an axis of rotation of the second rotating surface are on a same side and do not overlap, the first rotating surface is provided with a first stopper part, and the second rotating surface is provided with a second stopper part;
• the rotating shaft body further comprises a supporting surface, the supporting surface is provided on a same side as the axes of rotation of the two rotating surfaces, the supporting surface is concave toward the two rotating surfaces, and two sides of the supporting surface are provided with a third stopper part and a fourth stopper part respectively, wherein the first stopper part and the third stopper part are connected, to form a first stopping surface connecting the first rotating surface and the supporting surface;
• the second stopper part and the fourth stopper part are connected, to form a second stopping surface connecting the supporting surface and the second rotating surface.
