Upper cover in shape is additionally provided with light source between upper cover in lower cover and the annular in the annular, and the light source is fixed on described outer
On cover, it is provided with miniature webcam in lower cover in the annular, cross bar is fixedly installed on the telescopic rod, is set on the cross bar
It is equipped with display screen, the display screen and the miniature webcam are electrically connected, the light source, the sphere model and described micro-
The centre-height of type camera is identical.
Preferably, upper cover is identical as the outer diameter of lower cover in the annular in the annular.
Preferably, the bottom of the chassis is provided with universal wheel.
Preferably, the light source be LED Mini flash light and issue light be white light.
Preferably, the vertical range up and down in the annular in lower cover and annular between upper cover is less than the sphere model
Diameter.
The utility model has the beneficial effects that: present apparatus structure is simply easily assembled, rotary shaft drives outer cover rotation, simultaneously
Drive light source rotation, the notch formed between lower cover in upper cover and annular in annular for light source to the projection inside device, outside
Cover then prevents external light source from forming interference to inside, and light source rotates and project white light around sphere model annular, in the mistake of rotation
Cheng Zhong, will show the circulation change figure of each phases of the moon over the display, and what student can intuitively will be apparent that very much sees the phases of the moon
The whole process of variation.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
