Embodiment:

Below in conjunction with drawings and Examples the utility model is further described.

Embodiment 1: referring to figs. 1 through shown in Figure 7, a kind of sunshine earth demonstrator, comprise the chassis, rotating disk, the terminator support, terrestrial globe, laser aid, the noon sun plate, wherein, described chassis 1 is installed globe base 17 and is born rotating disk 2 with pad 13, globe base 17 puts terminator support 3, globe bracket 4 is plugged globe base 17, described globe bracket 4 is placed terrestrial globe 7, terrestrial globe 7 usefulness solid lines are with the equator, the north and south tropic and north and south polar circle overstriking, with dashed lines forms the day line overstriking, vertically be provided with terminator 6 and zodiacal circle 5 on the described terminator support 3, on the described rotating disk 2 support 9 is housed, inserts noon sun plate 8 or laser aid 20 on the support 9, described noon sun plate 8 usefulness clear sheets are made.Be laid with timeline 11 and division of day and night line 12 on the described rotating disk 2, and put on numeral and literal, also mark the scope that today and yesterday are arranged and sun apparent motion direction on the rotating disk 2; Be laid with on the described chassis 1 that the ecliptic dimension is several 14, solar term line 15, date line 16 and constellation line 18, and put on numeral and literal; Described chassis 1 is provided with chassis pin 10; Described
