Description

A kind of mathematics plotter

Technical field

The utility model relates to a kind of plotter, in particular to a kind of mathematics plotter.

Background technique

Currently, essential tool is plotter during mathematical education, the existing instrument used of drawing has directly Ruler, protractor, compasses and set square etc. need ceaselessly to change tool when drawing on blackboard, and the waste plenty of time draws, and And when carrying, situations such as being easy to appear few band, tool needs teacher firmly by blackboard, for a long time according to teacher being made to feel To tired, the effect drawn also will receive influence.Therefore, it is proposed that a kind of mathematics plotter.

Utility model content

The main purpose of the utility model is to provide a kind of mathematics plotters, can effectively solve asking in background technique Topic.

To achieve the above object, the technical solution that the utility model is taken are as follows:

A kind of mathematics plotter, including plotter, large-scale protractor, binding rope, three corner magnets, compasses and shaft A, it is described Plotter is made of the first ruler, the second ruler and third ruler, and it is straight that the second ruler upper and lower ends are separately installed with third Ruler and the first ruler, two sides and the first ruler and third ruler left side offer fixation hole to second ruler up and down, described Shaft A is installed, first ruler and third ruler left and right ends are equipped with three corner magnets, the third ruler on fixation hole Front side upper end is equipped with limiting slot, and the limiting slot lower end is equipped with compasses, and upper end is equipped with sliding block on the left of the compasses, and sliding Block is connect with limiting slot, and lower end is equipped with binding rope, first ruler and the second ruler junction on the right side of the third ruler Small-sized protractor is installed, shaft B is installed on the right side of first ruler upper end, movable plate is installed on the shaft B.

Further, second ruler front end middle position is equipped with handrail handle.

Further, third ruler lower end is equipped with large-scale protractor, and first ruler lower end is equipped with curve Ruler.

Further, scale strip is mounted on first ruler and the second ruler.

Further, it is opened up inside first ruler, the second ruler and third ruler fluted.

Compared with prior art, the utility model has the following beneficial effects:

1. the mathematics plotter of the utility model, by being equipped with three corner magnets, teacher drawing on the blackboard when, can pass through Ruler is adsorbed on blackboard by three corner magnets, is avoided teacher from needing the moment according to ruler, is expended a large amount of strength, and matter of imparting knowledge to students is influenced Amount.

2. the mathematics plotter of the utility model, by being equipped with compasses and small-sized protractor, two rulers directly can be with Required angle is measured by small-sized protractor, words bowlder directly can only use compasses, and reduction exchanges use for back and forth, and avoids Leak band and few band.

3. the mathematics plotter of the utility model, by being equipped with binding rope, when carrying, first with binding rope by three rulers It bundles, avoids ruler volume larger, it is directly inconvenient to carry.
