Abstract

The utility model provides a pair of multifunctional compasses. The multifunctional compasses are composed of a fixed rod (1), a triangular rule (2), a fixed tray (3), an angle gauge (4), a rotary rod (5) and a pen clamping holder (6). The multifunctional compasses are characterized in that the triangular rule (2) is arranged on the left side of one surface of the fixed rod (1), the angle gauge (4) is arranged on the right side of one surface of the fixed rod (1), and the fixed rod (1) is connected with the rotary rod (5) through a connection buckle. The multifunctional compasses have the advantages of being simple in structure, scientific in design and convenient to use. The fixed rod of the multifunctional compasses is provided with the triangular rule and angle gauge which are respectively provided with scales, and the fixed tray is arranged at the lower end of the fixed rod and can fix the fixed rod, so that the fixed rod does not shake when a circle is drawn and the circle is drawn accurately, meanwhile, the scale can be measured, and the multifunctional compasses are convenient and rapid to use, and improve the class efficiency.

Description

A kind of multifunctional compass
Technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of multifunctional compass.
Background technology
At present, compasses are the most frequently used schooling apparatus upper class hour concerning math teacher, use at any time, so the handy convenience of compasses has substantial connection to teacher's efficiency of attending class, at present, compasses for teaching has a variety of, and it is more single that general compasses just can be drawn circle, there is no scale, there is no set square etc., teacher also needs carefully to aim at scale for accuracy in use, also will take ruler to go to measure, very loaded down with trivial details, use very inconvenient.
Summary of the invention
The purpose of this utility model is to overcome above weak point, a kind of multifunctional compass is provided, on the compasses fixed bar, be provided with set square and the protractor of scale, the fixed bar low side arranges fixed disk, realize that teacher not only can draw circle but also can measurement scale when writing on the blackboard, convenient to use, improve the efficiency of attending class.
The purpose of this utility model is realized by following technical scheme, developed a kind of multifunctional compass, by fixed bar 1, set square 2, fixed disk 3, protractor 4 swingles 5, pen clip cylinder 6, formed, it is characterized in that: described fixed bar 1 one left side of face arrange set square 2 right sides protractor 4 are set, and fixed bar 1 is connected with swingle 5 by junction button.
Described fixed bar 1 low side arranges fixed disk 3, the end equipment pen clip cylinder 6 of swingle 5.
On described set square 2, protractor 4, be provided with graduation mark.
Described swingle 5 capable of rotating 180 degs.
Described protractor 4 is semicircle, and pen clip cylinder 6 is cylindrical.
Advantage of the present utility model: simple in structure, design science, easy to use, on the compasses fixed bar, be provided with set square and the protractor of scale, the fixed bar low side arranges fixed disk, and fixed disk can make fixed bar fix, reach picture bowlder fixed bar without rocking accurate picture circle, simultaneously again can measurement scale, convenient to use, improve the efficiency of attending class.
