Abstract: A lamp includes a casing, an elastic cover and a main body. The casing has an opening. The elastic cover covers the casing. The main body is disposed at the casing, and includes a base plate, a rotating element, a moving element, a linking-up element and a force member. The rotating element is pivoted to the base plate and located at the opening. The moving element is disposed at the base plate. Two ends of the linking-up element are connected to the rotating element and the moving element, respectively. The force member is connected to the moving element. When the force member receives a force, the moving element is moved from a first position to a second position, the linking-up element brings the rotating element to rotate away the base plate, and the rotating element is protruded from the opening, and pushes against the elastic cover.
