## Abstract

A drawing ruler used by mathematics teachers belongs to teaching supplies, wherein a set square is formed by connecting a ruler and two slide rulers, a graphometer is arranged on the inner side of the ruler, a protruding fixing leg perpendicular to the ruler is arranged at the left end part of the ruler, a sliding chute is formed on the ruler body of the ruler, and a pen holder capable of moving along the sliding chute is arranged inside the sliding chute; slide tracks are arranged on the slide rulers; the tops of the two slide rulers cross with each other and are connected in a sliding manner through sliding poles; the sliding poles are arranged inside the slide tracks; the two ends of each sliding pole are connected through fixing buckles; and the tail ends of the slide rulers are movably connected with the two ends of the ruler through pin shafts. The drawing ruler used by mathematics teachers has a simple structure, is convenient to use and has complete functions, integrates various teaching tools, and can be used as a ruler, a set square, a graphometer and a pair of compasses, and two edges of the set square can be adjusted so that the use is more convenient during teaching and drawing, and the application is wider.

## Description

The mathematics teacher uses the picture chi
Technical field:
The utility model belongs to realia, and particularly the mathematics teacher uses the picture chi.
Background technology:
In mathematical education, teacher will often use educational aids such as ruler, set square, graphometer and compasses, in existing realia, above-mentioned realia mostly is independently, can not be grouped together, so teacher teaches when using, need carry various realias, very trouble when leaving behind, then influences and lectures content on class.
The utility model content:
The utility model overcomes the deficiency of the problems referred to above, provides mathematics teacher a kind of simple in structure, easy to use, multiple functional to use the picture chi.
This mathematics teacher is achieved in that with the picture chi set square is formed by connecting by ruler and two slide rules, is provided with graphometer on said ruler inboard, is used for taking measurement of an angle; Vertical ruler is provided with outstanding fixing feet on the left part of said ruler, on the blade of ruler, be provided with chute, be provided with in the chute and can prolong the pen container that chute moves, be placed with chalk in the pen container, need the picture bowlder, said fixing feet is placed chalk as the center of circle in pen container, the rotary picture chi gets final product the picture circle then; Be provided with slideway on said slide rule, the top of two slide rules intersects and is slidingly connected by traveller, and said traveller is arranged in the slideway, and the two ends of traveller are connected by clip, and the end of slide rule flexibly connects by bearing pin and ruler two ends.
The utility model is simple in structure, and is easy to use, multiple functional.Collect multiple educational aid and one, can be used as ruler, set square, graphometer and compasses and use, and wherein two limits of set square can adjust, make when giving lessons mapping conveniently, use more extensive.
Description of drawings:
Accompanying drawing 1 is an overall structure schematic diagram of the present utility model, and accompanying drawing 2 is traveller schematic diagrames; 1, clip 2, slide rule 3, slideway 4, bearing pin 5, ruler 6, chute 7, graphometer 8, pen container 9, fixing feet 10, traveller
The specific embodiment:
In conjunction with the accompanying drawings 1 and accompanying drawing 2 embodiment be that the mathematics teacher uses the picture chi, is achieved in that set square is formed by connecting by ruler 5 and two slide rules 2, is provided with graphometer 7 on said ruler 5 inboards, is used for taking measurement of an angle; Vertical ruler 5 is provided with outstanding fixing feet 9 on the left part of said ruler 5, on the blade of ruler 5, be provided with chute 6, be provided with in the chute 6 and can prolong the pen container 8 that chute 6 moves, be placed with chalk in the pen container 8, need the picture bowlder, said fixing feet 9 is placed chalk as the center of circle in pen container 8, the rotary picture chi can the picture circle then; The top that is provided with 3, two slide rules 2 of slideway on said slide rule 2 intersects and is slidingly connected by traveller 10, and said traveller 10 is arranged in the slideway 3, and the two ends of traveller 10 are connected by clip 9, and the end of slide rule 2 flexibly connects by bearing pin 4 and ruler 5 two ends.
The utility model is simple in structure, and is easy to use, multiple functional.Collect multiple educational aid and one, can be used as ruler, set square, graphometer and compasses and use, and wherein two limits of set square can adjust, make when giving lessons mapping conveniently, use more extensive.
