Rotating Mechanism and Foldable Electronic Device

A rotating mechanism, comprising:

• a bearing base;
• a first fastening plate;
• a second fastening plate, wherein the first fastening plate and the second fastening plate are located on two opposite sides of the bearing base;
• a synchronization slider comprising a synchronization body, a first screw block and a second screw block, wherein the synchronization slider is slidably mounted on the bearing base, and wherein the first screw block and the second screw block are symmetrical relative to the synchronization body;
• a first synchronization swing arm comprising a first swing arm and a second swing arm, wherein the first synchronization swing arm is slidably and rotatably connected to the first fastening plate, wherein the first swing arm is detachably connected to the second swing arm, wherein the first swing arm comprises a first screw and the second swing arm comprises a second screw, and wherein the first screw and the second screw fit the first screw block;
• and
• a second synchronization swing arm comprising a third swing arm and a fourth swing arm, wherein the second synchronization swing arm is slidably and rotatably connected to the second fastening plate, wherein the third swing arm is detachably connected to the fourth swing arm, wherein the third swing arm comprises a third screw and the fourth swing arm comprises a fourth screw, and wherein the third screw and the fourth screw fit the second screw block,
• wherein the first synchronization swing arm and the second synchronization swing arm are respectively mounted on two opposite sides of the bearing base in a width direction and are rotatably connected to the bearing base, and
• wherein when the first synchronization swing arm or the second synchronization swing arm rotates relative to the bearing base, the first synchronization swing arm and the second synchronization swing arm can rotate simultaneously.

A foldable electronic device, comprising:

• a first housing;
• a second housing;
• a display;
