having a back center and being mounted to the inner surface of the inner covering board


1


, characterized in that a scored line


24


is provided across the outer covering board


2


such that the lower section


22


of the outer covering board


2


can be inclined outward to form a sloping position, and a pair of chains


23


having a stop


231


are mounted at one of the holes


222


along the bottom edge of the outer covering board


2


, or the hole


223
