A first support plate and a second support plate are respectively fastened to the first support arm and the second support arm. The first support arm and the first connecting frame are rotatably connected through a first arc-shaped sliding groove and a first arc-shaped arm that are in sliding fit. The second support arm and the second connecting frame are rotatably connected through a second arc-shaped sliding groove and a second arc-shaped arm that are in sliding fit.
