Abstract
The utility model relates to a multipurpose compasses and ruler combination, which comprises a movable leg 2, a fixed leg 3 and a rotary shaft 1. One end of the movable leg 2 is movably connected with one end of the fixed leg 3 by the rotary shaft 1. The multipurpose compasses and ruler combination is characterized in that a calculator 4 and a chalk clip 7 are disposed on the movable leg 2, and angular graduations 5, a level gauge 6 and a compasses pointed leg 8 are disposed on the fixed leg 3. The multipurpose compasses and ruler combination not only can be used for drawing circles, but also can be used as a ruler and a triangular ruler. By the aid of the multipurpose compasses and ruler combination, straightness of parallel lines can be kept when a geometric figure is drawn, the calculator brings convenience for simple calculation, a compasses can be folded after the figure is drawn, and then the multipurpose compasses and ruler combination can be used as a pointer and brings more convenience for a whole teaching process.
Description
Technical field
The utility model relates to a kind of compasses and ruler, belongs to a kind of teaching aid.
Background technology
At present, the most function singleness of existing educational compasses.In the teaching, will change teaching aid so continually by means of instruments such as ruler, set square, protractors, will certainly delay instructional blocks of time, also bring inconvenience simultaneously to teaching like need picture angle, rectangular co-ordinate and other geometric figures.
The utility model content
The purpose of the utility model is to provide a kind of compasses, ruler combination.Can not only directly draw circle, and can also the double as ruler etc. directly draw angle, coordinate and other geometric figures, convenience is provided for teacher's teaching.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of Napier's compasses chi; It by moving leg 2, decide leg 3 and rotating shaft 1 constitutes; An end that moves leg 2, decides leg 3 is through rotating shaft 1 flexible connection; It is characterized in that described moving leg 2 is provided with calculator 4 and chalk folder 7, describedly decide that leg 3 is provided with that angle is several 5, level meter 6 and compasses spur 8.
The beneficial effect of the utility model is: promptly can draw circle, can be used as ruler, set square use again.Draw straight that geometric figure can the keeping parallelism line.The convenient and simple calculating of calculator.After figure is finished, close up compasses and promptly can do the teacher's pointer use, make whole teaching convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 rotating shaft, 2 moving legs, 3 decide leg, 4 calculators, 5 angle numbers, 6 level meters, 7 chalks folder, 8 compasses spurs.
The specific embodiment
As shown in Figure 1.The utility model rotating shaft 1, moving leg 2 decide leg 3, calculator 4, angle is several 5, level meter 6, chalk folder 7, compasses spur 8 compositions.Its major technique characteristic is that compasses one end is provided with rotating shaft 1, and two ends are respectively equipped with chalk folder 7, compasses spur 8 in addition.The moving leg 2 of compasses, decide leg 3 and indicate the length number of division respectively.Also be provided with Simple Calculation device 4 on the wherein moving leg; Decide leg 3 and also indicate 90 °, 60 °, 45 °, 30 ° angle index number, be positioned at middle and be provided with a level meter 6 near rotating shaft 1 place.
During use, open compasses two legs, it is fixing that chalk is inserted chalk folder 7, both can make compasses and use; The moving leg 2 of compasses is selected according to 90 °, 60 °, 45 °, 30 ° angle index number deciding leg rotating shaft 1 place, and corresponding rectangular co-ordinate, triangle and parallelogram etc. can draw.The level meter of deciding on the leg 36 can guarantee the straight of straight line.Calculator 4 on the moving leg can provide the simple computation of data.Close up compasses two legs and can also do ruler and teacher's pointer use.
