The utility model provides a scissors formula telescopic machanism that mechanical deformation device, the main part is mechanical spheroid, and mechanical spheroid comprises 360 link member and 120 summit parts, adopts " football " formula structural design, and the surface is 32 bodies when opening, and 12 regular pentagon and 20 regular hexagon of being equalled by the length of side form, have the edge that 90 length are equal, and every edge alternately comprises the connecting rod that 4 root length degree are the same. The theory of cosmic expansion is set forth with a mechanical spheroid that can change irregularly to this exhibition device, the U. S. A that does and let spectator appreciate mechanical mechanism's motion, and can this spheroid be 1.2 meters 2.5 rice within range free shrinkage, the cooperation space is the inflation notion of dazzling color lamp light and active audio, the simulated space of transform constantly.
