Abstract
Multifunction compasses belong to study supplies and mainly solve the problems that traditional compasses are single in function, and a ruler and a protractor are not convenient to carry and easy to lose and damage. The multifunction compasses comprise a compasses body, the protractor is arranged at the top end of a rotating shaft of the compasses body, and a flexible ruler with size scale lines is arranged in the middle of a support leg of the compasses body. The multifunction compasses are simple in structure, capable of achieving measurement and drawing works, flexible to use, convenient, small in size, convenient to carry and particularly suitable for use of students and do not occupy spaces. In addition, a correlative structure can prevent stationary from being damaged and lost.
Description
Technical field
The utility model relates to a kind of study article, specifically a kind of multifunctional compass.
Background technology
Compasses are to be used for the instrument of picture circle and circular arc in mathematics and drawing, use compasses in the process of drawing circle, must at first confirm the center of circle and radius, are assurance drawing accuracy of gauge and picture quality; Radius and angle need use ruler and protractor to measure; But because ruler is flat, longer, when depositing and carry, fracture easily, multiple stationery also takes up room bigger; Be prone to lose, bring very big inconvenience to use.
The utility model content
The purpose of the utility model is to provide a kind of multifunctional compass, and these compasses have use, deposit the measurement function with convenience safe to carry and ruler and protractor.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of multifunctional compass; Its structure comprises the compasses body; The rotating shaft top of described compasses body is provided with protractor, is provided with the tape measure of a mark cun graduation mark at one midleg of compasses body.
The beneficial effect of the utility model is: during use, measure like need, draw back tape measure, make it to launch at the supporting leg place of compasses, unreeling of tape after accomplishing makes it to be wrapped in automatically on the compasses supporting leg; Protractor can be used for taking measurement of an angle simultaneously as the operating grip of compasses; The utility model is simple in structure, can realize the work of measuring and drawing simultaneously, uses flexibly, convenient, and volume is little, do not take up room, and is easy to carry, and the structure that is mutually related can prevent the damage of stationery and lose.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 compasses body, 2 protractors, 3 tape measures.
The specific embodiment
As shown in Figure 1.A kind of multifunctional compass, its structure comprises compasses body 1, the rotating shaft top of described compasses body 1 is provided with protractor 2, is provided with the tape measure 3 of a mark cun graduation mark at one midleg of compasses body 1.
During use, measure like need, draw back tape measure 3, make it to launch at the supporting leg place of compasses 1, unreeling of tape after accomplishing makes it to be wrapped in automatically on compasses 1 supporting leg; Protractor 2 can be used for taking measurement of an angle simultaneously as the operating grip of compasses 1; The utility model is simple in structure, can realize the work of measuring and drawing simultaneously, uses flexibly, convenient, and volume is little, do not take up room, and is easy to carry, and the structure that is mutually related can prevent the damage of stationery and lose, and especially is fit to the student and uses.
