Description
Technical field
The utility model is related to mathematical education field, more particularly to a kind of mathematical education plotter.
Background technology
In current mathematical education, generally require to use various drawing instruments, and drawing instrument is more in teaching
In be often difficult carry out, existing plotter relatively disperse, and draw during it cannot be guaranteed that line horizontality, to different angles
Angle be difficult measurement.Therefore, how drawing instrument is concentrated, and the horizontality of line is ensure that in drawing, can be to difference
Angle carry out angular surveying, be always the problem that the whole society faces.
Utility model content
The purpose of this utility model is to provide a kind of mathematical education plotter, to solve above-mentioned technical problem.
The utility model uses following technical scheme to achieve the above object：
First axle is provided with the middle part of a kind of mathematical education plotter, including chi body, the chi body, level meter and handwheel are pacified
On chi body, handwheel is connected by rotating shaft with drawstring, and drawstring end is provided with small sucker, and the chi body side is provided with drawer, draws
Ring is connected with drawer, and drawer is divided into independent cavity by dividing plate, and chi body top is provided with protractor, and the bottom of chi body is provided with hinge
The bottom plate of connection, bottom plate is provided with the top of set square, various sizes of circle, various sizes of ellipse, the chi body and is provided with opening,
And opening is located at below protractor, chi body two ends are provided with big sucker.
It is preferred that, the bottom plate is provided with the second axle with first axle identical position.
It is preferred that, fluorescence type graduated scale is provided with above the chi body.
It is preferred that, the width of the small sucker is more than the aperture of opening.
It is preferred that, the chalk of different colours is placed in the cavity.
It is preferred that, the width of the bottom plate is equal to the width of chi body.
Compared with prior art, the utility model has advantages below：The utility model is simple in construction, reasonable in design；Water
Level ensure that the horizontality of line, and chi body can be fixed for big sucker, and the bottom plate of gemel connection enters multiple types of tools
Row is concentrated, and drawstring and protractor can be measured to angle, draw angle, and first axle and the second shaft design can be carried out to chi body
Fold and reduce space, preferably promote the use of.

Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of mathematical education plotter, including chi body 2, the middle part of chi body 2 is provided with first axle 4,
Fluorescence type graduated scale is provided with above chi body, level meter 5 and handwheel 6 are installed on chi body 2, when level meter ensure that line
Horizontality, handwheel 6 is connected by rotating shaft with drawstring 15, and the end of drawstring 15 is provided with small sucker 14, and the width of small sucker is more than opening
Aperture, the side of chi body 2 is provided with drawer 8, and draw ring 9 is connected with drawer 8, and drawer 8 is divided into independent cavity 7 by dividing plate,
The chalk of different colours is placed in cavity, the chalk of different colours is easy to the progress of teaching, and the top of chi body 2 is provided with protractor 1, amount
Angle device and drawstring can be measured to angle, while different angles can be drawn, the bottom of chi body 2 is provided with the bottom that hinge 10 is connected
Plate 17, bottom plate 17 is provided with set square 11, various sizes of circle 13, various sizes of oval 12, and set square, circle, ellipse are easy to
Teaching is carried out, and the top of chi body 2 is provided with opening 16, and opening 16 is located at the lower section of protractor 1, and the two ends of chi body 2 are provided with big sucker
3, chi body can be fixed for big sucker.
Utility model works principle：When needing line, chi body, which is opened, to be rule, and level meter, which ensure that, to be drawn
Chi body can be fixed for the horizontality of line, big sucker, and drawstring and protractor can be measured to angle, and bottom plate is added
The function of chi body.
Described above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With new teaching, in the case where not departing from principle of the present utility model and spirit, the change that is carried out to embodiment, repair
Change, replace and modification is still fallen within protection domain of the present utility model.
