Synchronization mechanism, rotating shaft mechanism, and electronic device

An electronic device, wherein the electronic device comprises a rotating shaft mechanism, and the rotating shaft mechanism comprises a synchronization mechanism;

• the synchronization mechanism comprises a first swing arm, a second swing arm, a base, and a slider;
• the first swing arm and the second swing arm are located on both sides of the slider and are capable of rotating relative to the base;
• a sliding platform is disposed on a bottom part of the slider, a groove is disposed on the base, and the sliding platform fits the groove, so that the slider slides in a first direction, wherein the first direction is parallel to an axial direction of rotation of the first swing arm and the second swing arm;
• first fitting parts are symmetrically disposed on the first swing arm and the second swing arm along a center line of the base, second fitting parts are symmetrically on both sides of the slider along the center line of the base, and the second fitting parts correspond to the first fitting parts;
• and
• when the first swing arm and the second swing arm rotate relative to each other, the first fitting parts and the second fitting parts fit to drive the slider to slide in the first direction, so that rotation angles of the first swing arm and the second swing arm relative to the base keep consistent.
