Rotating shaft mechanism and foldable electronic equipment

The utility model relates to the field of folding equipment, aims at solving the problem that a staggered swing arm structure of a known rotating shaft mechanism is poor in supporting reliability, and provides a rotating shaft mechanism and foldable electronic equipment. The rotating shaft mechanism comprises a seat part, a first swing part and a second swing part. The first swing part comprises a first swing arm. One end of the first swing arm is rotatably connected to the seat part. The second swing part comprises a third swing arm. The third swing arm at least partially corresponds to the first swing arm in the first direction, and the space, used for being matched with the third swing arm, of the base part and the space, used for being matched with the first swing arm, of the base part are staggered in the section perpendicular to the rotating axis, rotating relative to the base part, of the first swing arm. The supporting device has the beneficial effects that supporting is stable, and the swing arms on
