Abstract
The invention relates to a multifunctional ruler capable of drawing various different figures. The multifunctional ruler comprises a first ruler, a second ruler, a first telescopic rod and a second telescopic rod, wherein the first telescopic rod is fixed to the middle part of the first ruler; the second telescopic rod is fixed to the middle part of the second ruler; the first ruler is perpendicular to the first telescopic rod and the second ruler is perpendicular to the second telescopic rod; the first telescopic rod is connected with the second telescopic through a shaft; lateral angles of the ends of the first ruler and the second ruler on the same side are acute angles, and the degree of the two acute angles is 90 degrees; the ends of the first ruler and the second ruler on the other side are cambered; the two ends of the first ruler and the second ruler are provided with magnets respectively; and the acute angle end of the first ruler or the second ruler is provided with a clamp. The multifunctional ruler has the beneficial effects of novel design and capabilities of meeting normal requirements of teaching and serving as a good teaching aid.
Description
Technical field
The present invention relates to a kind of multi-functional ruler of drawing multiple different graphic.
Background technology
Ruler is very extensive the teaching field application.And present ruler can only be drawn horizontal line mostly.And the teacher is in when teaching, and the study of Confucian classics needs some special figures of picture, like shapes such as circular, right angle or parallel lines; At this moment the teacher accomplishes above-mentioned drawing task, particularly when drawing parallel lines with regard to the many instruments of needs use, like compasses, set square and bevel protractor etc.; Use a set square; A ruler also will start to retouch line, and the basic not enough hand of people comes picture.And these instruments carry very inconvenient, in the time of use, need change different educational aids especially, waste time and energy.
Summary of the invention
The object of the invention provides a kind of multi-functional ruler of drawing multiple different graphic, and this ruler can satisfy teaching demand basically, and various figure draws.
The objective of the invention is to realize through following technical scheme:
A kind of multi-functional ruler of drawing multiple different graphic of the present invention; Comprise first ruler, second ruler, first expansion link, second expansion link, the middle part of said first ruler is fixed with first expansion link, and described second ruler middle part is fixed with second expansion link; First ruler and first expansion link; Second ruler and second expansion link are orthogonal, and first expansion link is connected with the second expansion link axle, and the lateral angle of the same side of first ruler and second ruler all is acute angle; It is 90 ° that the number of degrees of two acute angles are added up; Another side of first ruler and second ruler is all curved, respectively is provided with magnet at first ruler and the second ruler two ends, on an end of the acute angle of described first ruler or second ruler, is provided with clip.
Described first ruler, second ruler is preferably the ruler of equal length, and described first expansion link and second expansion link preferably are individually fixed in the midline position of first ruler and second ruler, and the acute angle of described first ruler and second ruler is 45 °.
The present invention through with ruler expansion link connected vertically, and first expansion link and second expansion link can rotate along axle, make two rulers an end closure that is acute angle at an angle of 90; Thereby make that two rulers are vertical each other; Like this, can use that the present invention draws parallel lines and the right angle, an end of the arc of two rulers is rotating closed through axle; Become the handheld terminal of compasses; And the acute ends of ruler that does not have Band clamp is as fulcrum, and the clip of another one ruler can be clamped chalk, thereby can be at the blackboard upper drawing circle.The two ends of ruler are provided with magnet can be with the present invention on blackboard, and an end of the acute ends of ruler can be arranged to certain number of degrees as required, as 30 °, 45 °, 60 °, therefore can use the acute ends of this ruler to draw the angle.
Beneficial effect of the present invention is: modern design, can satisfy the general needs of teaching, and be the good assistant of teaching.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the present invention is rotated into the sketch map in the time of drawing the right angle;
Fig. 3 is that the present invention is rotated into the sketch map when can do the compasses use.
The specific embodiment
Shown in Fig. 1-3: a kind of multi-functional ruler of drawing multiple different graphic of the present invention; Comprise first ruler, second ruler, first expansion link, second expansion link, the middle part of said first ruler is fixed with first expansion link, and described second ruler middle part is fixed with second expansion link; First ruler and first expansion link; Second ruler and second expansion link are orthogonal, and first expansion link is connected with the second expansion link axle, and the lateral angle of the same side of first ruler and second ruler all is acute angle; It is 90 ° that the number of degrees of two acute angles are added up; Another side of first ruler and second ruler is all curved, respectively is provided with magnet at first ruler and the second ruler two ends, on an end of the acute angle of described first ruler or second ruler, is provided with clip.
Described first ruler, second ruler is preferably the ruler of equal length, and described first expansion link and second expansion link preferably are individually fixed in the midline position of first ruler and second ruler, and the acute angle of described first ruler and second ruler is 45 °.
The present invention through with ruler expansion link connected vertically, and first expansion link and second expansion link can rotate along axle, make two rulers an end closure that is acute angle at an angle of 90; Thereby make that two rulers are vertical each other; Like this, can use that the present invention draws parallel lines and the right angle, an end of the arc of two rulers is rotating closed through axle; Become the handheld terminal of compasses; And the acute ends of ruler that does not have Band clamp is as fulcrum, and the clip of another one ruler can be clamped chalk, thereby can be at the blackboard upper drawing circle.The two ends of ruler are provided with magnet can be with the present invention on blackboard, and an end of the acute ends of ruler can be arranged to certain number of degrees as required, as 30 °, 45 °, 60 °, therefore can use the acute ends of this ruler to draw the angle.
