Abstract

The utility model relates to a drawing tool, particularly a multifunctional sector used for students, which comprises a lower ruler and an upper ruler, wherein the upper ruler and the lower ruler are rotatablely connected through a shaft sheath, one end of the upper ruler is provided with an indexing disc which is marked with scale numbers of angles of 0 to 360 DEG and the upper ruler and the lower ruler are respectively marked with the scales. The side end of the upper ruler is also provided with a positioning claw. The center of the shaft sheath is provided with a positioning device. The upper ruler is provided with a line drawing round hole which can be moved along a radial direction, and the line drawing round hole is matched with a slide way arranged on the upper ruler. The utility model has the advantages that the utility model can replace traditional rulers, triangles, protractors and compasses, and the multifunctional sector has multiple purposes, simple structure and convenient operation.

Description

Multi-functional ruler-compasses

Technical field

The utility model relates to a kind of drawing instrument, is specifically related to a kind of student and uses multi-functional ruler-compasses.

Background technology

The various drawing instruments of students use now are a feast for the eyes, drawing instrument commonly used includes set square, protractor, ruler, these drawing instrument structures and use singlely must just can be finished the mapping trouble in conjunction with multiple drawing instrument if draw the figure of a special angle, elapsed time is many, and multiple instrument carries also inconvenience very.

Summary of the invention

Problem to be solved in the utility model is to propose multi-functional ruler-compasses a kind of easy to use, simple in structure, easy to carry at above-mentioned prior art.

The utility model is adopted solution to be by the problem of the above-mentioned proposition of solution: a kind of multi-functional ruler-compasses, it comprises following chi, goes up chi, last chi and following chi are rotationally connected by axle sleeve, last chi one end is provided with index dial, index dial is marked with 0-360 ° angle index number, last chi and following chi indicate scale respectively, and last ulnar side end also is installed on locating detent, and the axle sleeve center is provided with positioner.

Press such scheme, the described chi of going up is provided with the setting-out circular hole that can radially move, and the setting-out circular hole matches with the slideway that is arranged on chi.

Press such scheme, described positioner is a pilot pin, and pilot pin is fixedlyed connected with locating shaft, is provided with spring in the locating shaft lower end.

Press such scheme, described locating shaft upper end also is provided with loam cake.

When the utility model was used as ruler, as long as last chi and the folding coincidence of following chi, at this moment, locating detent can will be gone up chi and following chi fixedly becomes a ruler;

When the utility model was used as angle square, will go up chi and following chi was coordinate system with the index dial, was converted into arbitrarily angle and came picture angle and angulation;

When the utility model is used as compasses, be the center of circle with the pilot pin loca, be that radius is drawn arc with the nib in paintbrush hole and the distance between the pilot pin loca, circle and circular arc can draw.

The utility model utilizes three degree of freedom, and promptly abscissa, ordinate and radian coordinate can be realized functions such as graphical pointv, straight line, angle and circular arc on a chi.

Advantage of the present utility model:

(1) the utility model can substitute traditional ruler, set square, protractor and compasses, and a chi is used more;

(2) it is simple in structure, and is easy to operate, has use value and economic worth preferably;

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model is further described in detail.

As Fig. 1, Fig. 2, Fig. 3, multi-functional ruler-compasses, it comprises chi 1 down, last chi 5, last chi and following chi are rotationally connected by axle sleeve 11, last chi one end is provided with index dial 7, index dial is marked with 0-360 ° angle index number, last chi and following chi indicate scale respectively, and last chi is provided with slideway 4, and setting-out circular hole 6 can radially move at last chi end along slideway, last ulnar side end also is installed on locating detent 3, locating detent mainly plays the effect of chi and following chi on the relative fixed, and it is pilot pin 10 that the axle sleeve center is provided with positioner, and pilot pin is fixedlyed connected with locating shaft 8, be provided with spring 9 in the locating shaft lower end, the locating shaft upper end also is provided with ornamental loam cake 2.When the utility model was used as ruler, as long as last chi and the folding coincidence of following chi, at this moment, locating detent can will be gone up chi and following chi fixedly becomes a ruler; When the utility model was used as angle square, will go up chi and following chi was coordinate system with the index dial, was converted into arbitrarily angle and came picture angle and angulation; When the utility model is used as compasses, be the center of circle with the pilot pin loca, be that radius is drawn arc with the nib in paintbrush hole and the distance between the pilot pin loca, circle and circular arc can draw.
