Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.
As shown in Fig. 1 ~ Fig. 5, a kind of physics teaching demonstrator, several connected including pedestal, pedestal upper spring are solid
Determine frame and is laid in the light barrier 1, lens 2 and light source 3 on fixed frame top respectively；
The pedestal includes big pedestal 4, the middle pedestal 5 being linked in big pedestal 4 and the small footprint being linked in middle pedestal 5
6, the section of the big pedestal 4, middle pedestal 5 and small footprint 6 is in U-shape, and the U-shaped upper end is equipped with inside flange, small footprint 6
It is laid with the first supporting block 7 and the second supporting block 8 respectively with one end lower surface of middle pedestal 5；
The fixed frame includes the telescopic support rod 9 in top and the spring pocket 10 for being fixed on 9 middle part of support rod, the branch
9 lower end of strut is located at chassis interior and is laid with bottom plate 11, is laid with first between the bottom plate 11 and pedestal U-shaped upper end flange
Spring 13, the spring pocket 10 is located above pedestal and is in the cylinder of lower ending opening, between spring pocket 10 and base upper surface
It is laid with mobilizable fixed plate 12, is laid with second spring 14 in the spring pocket 10.
