Embodiment
Below in conjunction with the drawings and the specific embodiments, the present invention is further detailed explanation.
First consult shown in Fig. 3, the connecting link 12 that teaching demonstrating model 10 of the present invention is adsorbed on magetic indicator joint 11 primarily of magetic indicator joint 11 and end formed, wherein, multiple magetic indicator joint 11 and many connecting links 12 mutually magnetic connect and compose solid geometry shape, the laser joint that one is provided with generating laser 13 is at least comprised in multiple magetic indicator joint 11, further, the spraying joint that is provided with dry ice sprayer 14 is at least also comprised in the multiple magetic indicator joints 11 beyond this laser joint.
Magetic indicator joint 11 is as the corner angle of solid geometry wire-frame model, connecting link 12 is as the crest line of solid geometry wire-frame model, multiple magetic indicator joint 11 and many connecting links 12 mutually magnetic connect and compose solid geometry shape, as wire-frame models such as quadrilateral body, trigones, by these wire-frame models can be visual in image be familiar with the space structure of the figure of different solid geometry shape, relation between crest line and summit, and the relation between crest line and crest line.
Shown in composition graphs 4, magetic indicator joint 11 can be spherical magnet, connecting link 12 is iron staff, and the end face of iron staff forms the cambered surface of the spherical surface corresponding to spherical magnet, when magetic indicator joint 11 and the mutual magnetic of connecting link 12 are connected, the curved end of connecting link 12 can seamlessly be adsorbed on the spherical surface of magetic indicator joint 11, both close contacts, thus the figure stably forming various solid geometry shape.
Consult again shown in Fig. 5, as preferred embodiment, magetic indicator joint 11 also can be to be combined with the magnet layer 112 being coated on spheroid 111 surface by spheroid 111 to form, connecting link 12 is then for end is provided with the hollow or solid bar of iron block 121, and the end face being located at the iron block 121 of the end of connecting link 12 forms the cambered surface of the magnet layer 112 corresponding to magetic indicator joint 11, when magetic indicator joint 11 and the mutual magnetic of connecting link 12 are connected, connecting link 12 the curved end of iron block 121 be seamlessly adsorbed on the magnet layer 112 on magetic indicator joint 11 surface, both close contacts, stably form the figure of various solid geometry shape, wherein, the shape of connecting link 12 is not limited to illustrated linear, it can also be arc.
