Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Be illustrated in figure 1 structural representation of the present utility model,
Reference numeral is wherein: body 1, length scales 11, centre of figure are determined region 2, abscissa 21, ordinate 22, hollow-out parts 23, parallelogram mapping region 3, upper angle scale 31, altitude scale 32, lower angle scale 33, pointer 4.
As shown in Figure 1,
A kind of multifunction graphics surveying and mapping tool, comprise the body 1 of being made by transparent plastic, wherein, body 1 upper end edge length direction is provided with length scales 11, on body 1, be provided with centre of figure and determine region 2, this centre of figure determines and in region 2, is provided with the reference axis that orthogonal abscissa 21 and ordinate 22 form, and abscissa 21 and ordinate 22 intersect and form central point in midpoint, and this center position is provided with hollow-out parts 23.The parallelogram mapping region 3 of hollow out is set on body 1, these parallelogram mapping region 3 rectangularity structures, the top in this parallelogram mapping region 3 is provided with upper angle scale 31, and its right and left is respectively arranged with altitude scale 32.
In embodiment, parallelogram mapping is provided with the pointer 4 that can rotate taking initial point place, the lower left corner as the center of circle on region 3.The setting of pointer 4 greatly facilitates determining of corner dimension, rotating pointer 4, and its indication angle is the size of horizontal sides and inclined side institute angle, can be easy to obtain the angle of required size by pointer 4, also can ensure the accuracy of drawn angle.In the time of drawing inclined limit, pointer 4 can be worked as to ruler and use, simple and convenient.
