The side wall of the fan-shaped plate 2 has evenly arranged slots, and a cardboard 4 is inserted into the slot. The lower side of the cardboard 4 contacts the upper side of the plane mirror 3. An angle adjustment mechanism is fixed to the front side of the storage plate 1, and a limit clamping mechanism is fixed to the upper end of the angle adjustment mechanism. The angle adjustment mechanism can be used to adjust the rotation angle of the limit clamping mechanism, and the limit clamping mechanism is used to limit and fix the cardboard 4.
