Abstract
A rotary mechanism is provided, including a first housing, a second housing, a rotary module, an elastic element, and a speed-reduction module. The rotary module connects to the first housing and extends therefrom to connect with the second housing. The elastic element connects the second housing and the rotary module. The speed-reduction module connects to the rotary module. When an external force is exerted on the second housing, and the second housing rotates relative to the first housing along a first direction, the elastic element stores an elastic potential energy. When the external force is released, the second housing rotates relative to the first housing along a second direction by the elastic force. The second direction is opposite to the first direction, and the speed-reduction module reduces the rotary speed of the second housing relative to the first housing.
