Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
A kind of multifunction wheat leaf characters measurement device as shown in FIG. 1 to 3, including length measuring ruler 1, width are surveyed
Gage 2 and colorimetric ruler 3, the colorimetric ruler 3 are articulated and connected with 1 end of length measuring ruler by articulated shaft, the linear measure longimetry
The surface of ruler 1 is provided with length mark 11, and 2 vertical sliding motion of width measuring scale is connected on length measuring ruler 1, width measurement
It is provided with the width mark 21 vertical with length mark 11 on ruler 2, is provided with several color lumps 31, the ratio on the colorimetric ruler 3
The back side of color ruler 3 is fixedly connected with an arc connector 4 extended towards 1 direction of length measuring ruler, on the arc connector 4
