Abstract
The utility model discloses a mathematics teaching plotter. The plotter comprises a stem, a drawing branch and a centering branch, wherein the drawing branch and the centering branch are connected with the stem through a hinge plate; a positioning mechanism is arranged on the end part of the centering branch, and is connected with the centering branch through a spherical hinge head; a chalk clamping mechanism is arranged on the end part of the drawing branch; a sizing ruler is arranged between the centering branch and the drawing branch; a button switch is arranged on the hinge plate; a power supply module is arranged in the stem; an indicating lamp head is arranged on the head part of the stem; the indicating lamp head, the power supply module and the button switch are electrically connected. The mathematics teaching plotter is simple in structure and novel in structure, is convenient, quick and easy to operate when being used for drawing a pattern, can be used for guaranteeing the consistency of fixed circle center and radius, and can be used for teaching demonstration by the indicating lamp head, so that the teaching efficiency is improved.
Description
Technical field
The utility model relates to a kind of teaching aid technical field, relates in particular to a kind of mathematical education diagraph.
Background technology
At present, the explanation of often need to mapping on blackboard in the mathematical education process is demonstrated, especially how much and function explanation, and mapping becomes important auxiliary explanation means, but the method that present math teacher mainly adopts is manual drawing, the hand-held drawing instrument of teacher and chalk are drawn on blackboard, while especially painting circle, more complicated, hand-held compasses, should guarantee that the center of circle is constant, guarantee that again radius is constant, be difficult to operation.Existing drawing tool function singleness.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of mathematical education diagraph.
To achieve these goals, the technical solution adopted in the utility model is: a kind of mathematical education diagraph, comprise stem, drawing branch and centering branch, drawing branch is connected with stem by hinged disk with centering branch, the end of centering branch is provided with detent mechanism, detent mechanism is connected with centering branch by the globular hinge head, the end of drawing branch is provided with the chalk clamping device, between centering branch and drawing branch, be provided with the sizing scale, hinged disk is provided with key switch, in stem, be provided with power module, the head of stem is provided with indicating light holder, indicating light holder, power module and key switch are electrically connected to.
As preferably, power module is lithium ion battery.
Compared with prior art, the utility model has the advantage of: simple in structure, modern design, convenient and swift while drawing a design, simple to operate, can guarantee that the center of circle is constant, can guarantee that again radius is constant.Simultaneously can also carry out teaching demonstration by indicating light holder, improve efficiency of teaching.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, stem; 21, drawing branch; 22, centering branch; 3, hinged disk; 4, globular hinge head; 5, detent mechanism; 6, sizing scale; 7, chalk clamping device; 8, key switch; 9, indicating light holder.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As a kind of embodiment of the present utility model, consult Fig. 1, the utility model comprises stem 1, drawing branch 21 and centering branch 22, drawing branch 21 is connected with stem 1 by hinged disk 3 with centering branch 22, the end of centering branch 22 is provided with detent mechanism 5, detent mechanism 5 is connected with centering branch 22 by globular hinge head 4, the end of drawing branch 21 is provided with chalk clamping device 7, between centering branch 22 and drawing branch 21, be provided with sizing scale 6, hinged disk 3 is provided with key switch 8, in stem 1, be provided with power module, the head of stem 1 is provided with indicating light holder 9, indicating light holder 9, power module and key switch 8 are electrically connected to.Power module is lithium ion battery.
The utility model is simple in structure, and modern design is convenient and swift while drawing a design, simple to operate, can guarantee that the center of circle is constant, can guarantee that again radius is constant.Simultaneously can also carry out teaching demonstration by indicating light holder 9, improve efficiency of teaching.
Although in conjunction with current, be recognized as a most practical and preferred embodiment and described the utility model, but be to be understood that, the utility model is not limited to the disclosed embodiments, and is intended on the contrary contain multiple modification and equivalent arrangements included in the spirit and scope of the appended claims.
