Fig. 1 is the structure front view of diamond ratio instrument described in the utility model embodiment；
Fig. 2 is the structural side view of diamond ratio instrument described in the utility model embodiment；
Fig. 3 is the structure diagram of the specimen holder described in the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Please refer to Fig.1, shown in Fig. 2, a kind of diamond ratio instrument provided by the utility model, including upper shell 1, projection screen
2nd, the back of stent 3, projective amplification mirror 4, specimen holder 5 and base 6, upper shell 1 and base 6 is connected by stent 3, the branch
Frame 3 is a metallic plate, adds the distance of upper shell 1 and base 6, is mounted with light source 7 inside base 6, corresponding light source on base 6
7 are equipped with opening, and light source 7 illuminates straight up, and the switch 8 of control light source 7 is mounted with base 6, sample is movably set with opening
Product folder 5, specimen holder 5 and base 6 are linked together by magnet, and specimen holder 5 can move, and projective amplification mirror 4 is arranged at sample
Simultaneously there is interval in the surface of folder 5, the upper end of projective amplification mirror 4 is connected with upper shell 1, projective amplification mirror 4 between specimen holder 5
Lower end be provided with quasi- focus knob 41, the middle part of projective amplification mirror 4 is provided with amplification knob 42, and amplification knob 42, which is used to control, to be thrown
The amplification factor of shadow, quasi- focus knob 41 are used for the clarity for adjusting projection, are provided with reflective mirror 9 in upper shell 1, reflective mirror 9 is in
45 ° of angles are obliquely installed to be provided with projection screen 2, throws in the surface of projective amplification mirror 4, the anterior positions of panels of upper shell 1
