The utility model has the advantages of novel design and convenient operation. The multifunction learning ruler can conveniently complete the manufacture of various patterns, such as a straight line, a circle, a curve and an angle measurement, and is the learning tool with multifunction.
Description
The utility model relates to a kind of schooling apparatus, particularly a kind of multifunctional learning tool ruler.
The schooling apparatus that existing market is sold, it all is single sale and use that ruler, protractor, the compasses of band scale are arranged respectively, the ruler size broad that has, there are a plurality of empty graphics the centre, and empty graphic is respectively triangle, rectangle, trapezoidal, square, ellipse etc.These schooling apparatus exist function, problem that purposes is single, and quantity is more, and particularly students in middle and primary schools carry very inconveniently, and it is also inconvenient to draw the circle operation with compasses.
The purpose of this utility model just is to solve the problem of above-mentioned existence, provide a kind of of many uses, function is more, it is convenient to draw circle, accurate in size multifunctional learning tool ruler.
The technical solution of the utility model is achieved in that it comprises ruler, protractor, empty graphic and arc lace, is processed with the small sircle hole that two row can penetrate ruler in the scale limit of ruler, and the scale limit of this two row small sircle hole and ruler all is parallel shape.
This multifunctional learning tool ruler can the many usefulness of a chi, and modern design is easy to use, and scale is accurate, are easy to draw circle especially.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a front view of the present utility model;
As shown in the figure: this multifunctional learning tool ruler, the left side is a protractor, the right is the ruler 1 of band scale, the size broad of ruler 1, the top has scale, be processed with two row sizes and can penetrate the small sircle hole 2 and 3 of ruler 1 in this scale limit, be processed with the empty graphic 5 of different shape below the scale limit, tool ruler bottom is an arc lace 6.This multifunctional learning tool ruler is a transparent plastic material, adopts Mould Machining to be shaped, and protractor 4 can the measuring angle size, and ruler can be drawn the right angle, and empty graphic 5 can be drawn triangle, square, trapezoidal etc., and arc lace 6 can be drawn the arc lace.The tip of article such as picture bowlder pencil, ball pen is small sircle hole 2 or 3 fixedly, then pencil or ball pen is penetrated your required radius of a circle small sircle hole, revolves around central point and turns around, and promptly gets required circle.
