Abstract
The utility model discloses a novel geometric teaching aid which is characterized in that a chute is arranged in the middle part of a ruler which is coupled with the circle center of a protractor through a rotary shaft and the chute. Through above arrangement, the ruler and protractor are combined, so that the novel geometric teaching aid provided by the utility model can measure both length and angle. Angles in different angles can be further drawn up by adjusting the position of the ruler on the protractor. The novel geometric teaching aid provided by the utility model is simple in structure and convenient to carry.
Description
Technical field
The utility model relates to a kind of teaching aid, is how much teaching aids of a kind of novel combined type specifically.
Background technology
The teacher usually can use protractor and ruler and be engaged in the blackboard picture, but present protractor and ruler all is single product that cooperating to draw at blackboard wastes time and energy, and carries inconvenience in several teaching.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, uses how much teaching aids of novel combined type easy to carry.
To achieve these goals, the utility model is provided with chute in the middle part of ruler, and ruler is linked together by the circle centre position of rotating shaft and chute and protractor, is provided with the length scale at described ruler, is provided with angle index at described protractor.
By above setting, the utility model combines ruler and protractor, can measure length, and angle that again can measured angular can also by adjusting the position of ruler on protractor, draw the angle of different angles.The utility model is simple in structure, is easy to carry
Description of drawings
Now by reference to the accompanying drawings the utility model is described further.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, ruler, 2, chute, 3, rotating shaft, 4, protractor.
The specific embodiment
As shown in Figure 1, the utility model is provided with chute 2 in the middle part of ruler 1, and ruler 1 is linked together by the circle centre position of rotating shaft 3 and chute 2 and protractor 4, is provided with the length scale at described ruler 1, is provided with angle index at described protractor 4.By above setting, the utility model can be measured length by ruler 1, and angle that again can throughput hornwork 4 measured angular can also by adjusting the position of ruler 1 on protractor 4, draw the angle of different angles.
