Expandable yin and yang Eight Diagrames steromodel

The utility model discloses an expandable yin and yang Eight Diagrames steromodel, witch is characterized in that : the movable connecting base assembly connects in support four combined structures formed by two small cubes connected with each other to form the variable space stereo-structure. The movable connecting base assembly is the base assembly of two ' second steps' connected with each other through a chute-slip joint meshing structure. The assembly connects in support the variable space stereo-structure formed by the above four small cubes combined structure. In other words, on one hand, the base assembly of the two ' second steps' connects in support the yin and yang eight diagrams stereo-structure with specific spatial arrangement formed by the eight small cubes used to configure the eight diagrames correspondingly. On the other hand, the eight small cubes used to configure the Eight Diagrames and the base part carry out displacement change and developing gradually through the chute, the slip joint and the relevant assembly. The eight diagrames plane arrangement whose hierarchy and order relation are displayed by the base part is formed finally.
