A foldable and retractable mechanism includes a first body and a second body. The first body includes a first connection member. The second body is configured to rotate relative to the first body and including a second connection member. The first connection member and the second connection member are assembled in movable manner. The first connection member and the second connection member are configured to be in a retracted state, in which the first connection member and the second connection member at least partially overlap with each other and constraint relative rotation of the first body and the second body. The first connection member and the second connection member are configured to be in an extended state, in which the first connection member is away from the second connection member, and the second body is rotatable and capable of being folded over the first body.
