Abstract
The utility model discloses a multifunctional ruler with graduated scales and a protractor, which belong to drawing articles, and is particularly applied to study for middle school students. The multifunctional ruler comprises the graduated scales and the protractor, and is characterized in that the cross point of the centre lines of the graduated scale A and the graduated scale B and the centre point of the protractor are fixed together by a centre shaft with a rotary knob, so that the two graduated scales can rotate around the shaft. The multifunctional ruler with the graduated scales and the protractor has the beneficial effects that as the graduated scale A and the graduated scale B and the protractor are fixed together by the rotary knob, an angle needed is measured by the protractor, and the angle with known side length is drawn by rotating the graduated scale. The multifunctional ruler with the graduated scales and the protractor has simple structure, and is convenient for use and carrying.
Description
Technical field
The utility model belongs to drawing article, particularly the study article of middle school student's use.
Background technology
Various rulers and protractor are the most frequently used drawing instruments of student, general ruler and protractor branch are arranged, when drawing the angle of known length of side length, need find out the draw length on known limit of ruler, find out the angle that protractor draws to be needed again, lose time, divide the ruler and the protractor that are arranged also to be not easy to carry simultaneously.
The utility model content
Be arranged and carry inconvenient deficiency in order to overcome ruler and protractor branch, the purpose of this utility model provides a kind of scale angulation multifunctional ruler, the angle that this scale angulation multifunctional ruler can the very convenient known length of side length of drawing.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of scale angulation multifunctional ruler, comprise rule and protractor, it is characterized in that: the crosspoint of the center line of scaleover chi A and rule B and the centre point of protractor are fixed together by the central shaft that has knob, and two rules can rotate around the axis.
The beneficial effects of the utility model are because rule A, rule B and protractor are fixed together by the central shaft that has knob, measure the angle that need draw with protractor, the draw angle of the known length of side of rotation rule.The utility model is simple in structure, easy to use, be easy to carry.
