The bottom end surface of the movable plate 3 is in movably contact with the top end surface of the setting plate 2. When the two movable plates 3 move, the first angle plate 5 and the second angle plate 6 installed in the rotating groove 4 will produce an angle change due to the movement of the movable plate 3.
