Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structure enlarged diagram of clear glass disk.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.
As shown in figure 1, this utility model includes pedestal 13, it is fixed with support frame 1 on 13, on the top of support frame 1
Portion 2 is rotatably connected to the rotating shaft 4 being vertically arranged, and the lower end of described rotating shaft 4 is located in support frame 1 and is provided with rotating shaft 4 lower end
Installing hole 16, is fixed with horizontally disposed clear glass disk 3 on the top of rotating shaft 4 by connector 15, in order to preferably right
Incidence vane to be calibrated or the fixation of angular transducer, are provided with instrument mounting seat 17 on the pedestal 13 immediately below rotating shaft 4, peace
Dress seat 17 is located in support frame 1；As shown in Fig. 2 being along the circumferential direction provided with quarter at the top surface edge of clear glass disk 3
Angle value 18, the scale division value of described scale value 18 is 1 °；The cunning pointing to rotating shaft 4 axis is provided with the pedestal 13 outside support frame 1
Rail 14, slidably connects slide 12 on slide rail 14, is fixed with platform 10 and hand-to-arm grip 11, fixes on platform 10 on slide 12
There is light source 5, slide up and down in the top ends of hand-to-arm grip 11 and be connected with collection lenses 6, described image collection camera lens 6 is located at light source
