Abstract

The utility model belongs to a multifunctional caliper which integrates functions of a traditional caliper, a flat ruler, a set square, and an angle gage, which provides for teaching and scientific researching, and can measure angle and length, and can draw circles. The utility model is made of high hardness transparent material, which comprises a short foot (1), a long foot (2), and an angle gage (3). A semi-circle-shaped angle gage (3) is designed on one end of the long foot (2), and a needle point (4) is arranged on the other end, which is used for a circle center when a circle is drawn. Scale marks are arranged on the short foot (1) and the long foot (2), which can be used as a flat ruler to measure length. A starting point on one end of the short foot (1) is on the circle center of the angle gage (3), the short foot (1) can be used with the angle gage (3) to measure angles, and a writing-core (5) can be placed on the other end to draw a circle.

Description

Multifunctional compass

Technical field:

The utility model belongs to a kind of novel drawing instrument that has merged traditional compasses, ruler, set square, protractor function.

Background technology:

Take measurement of an angle, length, circle tool is often to use in teaching, the drawing work, and is how convenient, accurately directly have influence on the efficient of teaching, drawing work.At present the above-mentioned instrument that uses mostly is traditional compasses, ruler, set square, protractor, and function singleness is carried inconvenience, and the production cost height can not satisfy teacher, student and scientific research personnel's needs.

Teaching, be badly in need of in the drawing work a kind of can merge take measurement of an angle, the drawing instrument of length, the multiple function of picture circle, increase work efficiency.

Summary of the invention:

Main task of the present utility model is to provide a kind of novel drawing instrument that merges can the taking measurement of an angle of traditional compasses, ruler, set square, protractor function, length, picture circle for teaching and scientific research work.

The utility model is achieved in that it makes with the high-hard, transparent plastics, is made of short pin, long pin, protractor three parts.Have scale on short pin and the long pin, can work as ruler and use, measure length.Short pin one end starting point is positioned at the center of circle of protractor, can use together with protractor to take measurement of an angle, and the other end can be placed pen core, is used for the picture circle.Long pin one end design has protractor, and other end design has needle point, draws bowlder as the center of circle.

Advantage of the present utility model is: length, angle function are justified, measured to the picture that merges traditional compasses, ruler, set square, protractor in one, uses simply, and be easy to carry, helps increasing work efficiency; The huge market demand, production cost is low, is convenient to marketing.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Among Fig. 1, the 1st, short pin, the 2nd, long pin, the 3rd, protractor, the 4th, needle point, the 5th, pen core.

Embodiment:

In conjunction with the accompanying drawings embodiment of the present utility model is described further: the long pin (2) of this novel bow compass, short pin (1) can be used to measure length, be the center of circle with the needle point (4) of long pin (2) one ends, and the pen core (5) that rotates short pin (1) one end can come the picture circle.Protractor (3) and short pin (1) can be used for taking measurement of an angle together, and the one side with institute's angle measurement during measurement overlaps with the base of protractor (3), rotate short pin (1) to overlapping with the another side of institute angle measurement, can read angle numerical value from protractor (3).

Claims

1. multifunctional compass, it is characterized in that: it is made with the high-hard, transparent plastics, constitute by short pin (1), long pin (2), protractor (3) three parts, have scale on short pin (1) and the long pin (2), long pin (2) one ends design has semicircle protractor (3), other end design has needle point (4), draws bowlder as the center of circle.

2. according to the described multifunctional compass of claim 1, it is characterized in that: short pin (1) one end starting point is positioned at the center of circle of protractor (3), and protractor (3) uses together and take measurement of an angle, and the other end is placed the pen core (5) of picture bowlder use.
