Foldable apparatus and electronic device

An electronic device, wherein the electronic device comprises a first housing, a second housing, a flexible display, and a foldable apparatus, wherein

• the first housing and the second housing are located on two sides of the foldable apparatus, and the flexible display covers the first housing, the second housing, and the foldable apparatus, and is fastened to the first housing and the second housing;
• and
• wherein the foldable apparatus comprises:
• a fastened piece;
• and
• a rotating assembly, wherein the rotating assembly comprises a first rotating arm and a second rotating arm that are arranged on two sides of the fastened piece in a width direction of the foldable apparatus, and the first rotating arm and the second rotating arm can rotate relative to the fastened piece, to enable the foldable apparatus to be in a folded state or an unfolded state, wherein
• the foldable apparatus further comprises a stopper, the stopper is fastened to the fastened piece or connected to the fastened piece in a position-limiting manner, and when the first rotating arm and the second rotating arm rotate opposite to each other until the foldable apparatus is in the unfolded state, the stopper abuts against the rotating assembly, to restrict the first rotating arm and the second rotating arm from continuing to rotate opposite to each other.
