1. A hinge mechanism, applied to a foldable mobile terminal, wherein the hinge mechanism comprises:
a main shaft component;
a swing arm component, comprising at least one swing arm group, wherein each swing arm group comprises swing arms correspondingly disposed on both sides of the main shaft component, the swing arm component is rotatably connected to the main shaft component, and axes around which the swing arms on both sides of the main shaft component rotate are different and are separately parallel to an extension direction of the main shaft component; and
a synchronization component, wherein the synchronization component and the swing arm component are correspondingly disposed, the synchronization component comprises synchronization arms separately disposed on both sides of the main shaft component, and two synchronization arms are geared; and each synchronization arm is slidably connected to a swing arm on a same side as the synchronization arm, and is configured to rotate with the swing arm on the corresponding side, and wherein axes around which a swing arm and a synchronization arm disposed on a same side rotate coincide.
