The specific embodiment
A kind of multipurpose geometric plotter as shown in Figure 1, comprise ruler 1, protractor 2 and ruler 23, described ruler 1 is provided with straight trough 4, be slidingly fitted with slide block 5 in this straight trough 4, one end of described ruler 1 is provided with detachable compasses cap 14, the other end of ruler 1 is installed with compasses point 6, between described slide block 5 and the compasses point 6 flexible cord 7 is installed, one side of described ruler 1 is connected with the base of protractor 2, be disposed with half slot 8 and semicircle orifice 9 in this protractor 2, be slidingly fitted with holding screw 11 in the half slot 8, one end of described ruler 23 is equipped with lead core cover 12, these lead core cover 12 inside are provided with pencil-lead 13, and the other end of ruler 23 is provided with reinforcement 10, and ruler 23 is installed on ruler 1 and the protractor 2 by reinforcement 10 and holding screw 11.
As shown in Figure 1, the center of circle of equal throughput hornwork 2 places, one side of ruler 1 and ruler 23 circle, the fixing point between ruler 1 and the ruler 23 is the center of circle of protractor 2 places circle.This kind design can make this multipurpose geometric plotter measure the angle at any angle easily, and can draw the triangle of determining angle arbitrarily.
As shown in Figure 1, the thin and thick middle in the both sides of ruler 1 and ruler 23, the top margin of protractor 2 is thin and the base is thick, is skewed.This kind design can make this multipurpose geometric plotter mapping convenient, accurate.
As shown in Figure 1, ruler 1, protractor 2 and ruler 23 are certain flexibility and moderate non-toxic transparent plastic or the lucite of hardness, and described flexible cord 7 is the high nylon wire of toughness.Transparent plastic or lucite can be seen the figure below the multipurpose geometric plotter easily clearly, and it is more accurate to map.It is convenient that nylon wire has good flexible to draw, and can use for a long time.
The course of work of the utility model multipurpose geometric plotter is: during use, ruler 23 can arbitrarily rotate in 180 ° of scopes by forward and reverse on ruler 1 and the protractor 2, when ruler 23 is turned to 180 °, tighten the holding screw 11 that is positioned at half slot 8, ruler 1 and ruler 23 are formed a long ruler, can draw long straight line; When ruler 23 was positioned at 90 °, ruler 1 and ruler 23 were formed a rectangular coordinate system, can draw rectangular co-ordinate easily.
