Embodiment Construction
[0035] in figure 1 , figure 2 , image 3 with Figure 4 In the schematic diagram of the polyhedral ball-and-stick model shown, the geometric model polyhedron 1 includes a regular polyhedron composed of congruent regular polygons, a semi-regular polyhedron composed of two or more regular polygons, and a polyhedron composed of other polygons. It is a hollow polyhedron. The thickness of the solid part must meet the stability of the connecting rod when inserting and connecting. A circular hole slot 2 with the same diameter and depth is provided at the center of each surface. The area of the circular hole slot is smaller than that of each polygon on the polyhedron. The diameter of the circular hole groove matches the diameter of the end of the cylindrical connecting rod 3, so that the end of the connecting rod can be inserted into the circular hole groove on each face of the polyhedron; the connecting rods are cylindrical connecting rods of different lengths, The diameter of the ...
