Abstract: A hinge is provided. The hinge includes a first connection element, a second connection element, a first elastic element, and a second elastic element. The second connection element is connected to the first connection element. The first elastic element is connected to the first connection element. The second elastic element is connected to the first elastic element. The first elastic element drives the second elastic element to rotate relative to the second connection element. The first elastic element is rotatable between a first limit position and a second limit position. When the first elastic element is in the first limit position, the second elastic element is compressed.
