Abstract
The utility model relates to a dividing ruler capable of drawing an angle and belongs to the stationery. The dividing ruler mainly solves the problem that the prior protractor can not directly be used for drawing the angle. The structure of the dividing ruler mainly consists of a primary dividing ruler, a protractor and a secondary dividing ruler, wherein the protractor is fixedly arranged at the end part of one side of the primary dividing ruler, scale lines are marked at the other side of the primary dividing ruler, and a circle center of the protractor is hinged with the secondary dividing ruler through a rotating shaft. The circle center of the protractor fixed at one end of the primary dividing ruler is hinged with the secondary dividing ruler through the rotating shaft so that the dividing ruler can draw angle lines accurately and quickly through rotating the secondary dividing ruler, thereby reducing the drawing work strength and facilitating use.
Description
Technical field
The utility model relates to a kind of stationery, specifically a kind of rule.
Background technology
Rule and protractor all are student's essential stationery when learning to draw, but existing protractor only can take measurement of an angle, and can't directly draw angle, makes troubles for drawing work.
The utility model content
The purpose of this utility model is to provide a kind of rule that can draw angle, mainly solves the problem that the standing crop hornwork can't directly be drawn angle.
The technical scheme in the invention for solving the technical problem is: a kind of rule that can draw angle, its structure is made up of master calibration chi, protractor and secondary rule, one side end of described master calibration chi is set with a protractor, the opposite side of master calibration chi is carved with graduation mark, and the center of circle of described protractor is by rotating shaft hinged one secondary rule.
The beneficial effects of the utility model are: the center of circle of protractor of an end that is fixed on the master calibration chi is by rotating shaft hinged one secondary rule, by the revolute pair rule can prepare, the angle line that draws fast, reduced the working strength of drawing work, made things convenient for use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 master calibration chi, 2 rotating shafts, 3 protractors, 4 secondary rules.
The specific embodiment
As shown in Figure 1.A kind of rule that can draw angle, its structure is by master calibration chi 1, protractor 3 and secondary rule 4 are formed, one side end of described master calibration chi 1 is set with a protractor 3, the opposite side of master calibration chi 1 is carved with graduation mark, the center of circle of described protractor 3 is by rotating shaft 2 hinged one secondary rules 4, revolute pair rule 4, make need on the end amount of alignment hornwork 3 of secondary rule 4 picture angle line, by the identical principle of diagonal angle angle, use the other end of secondary rule 4 angle line that draws, the drafting angle is prepared, fast, reduce the working strength of drawing work, made things convenient for use.
Claims (1)
1. the rule that can draw angle, it is characterized in that, form by master calibration chi, protractor and secondary rule, one side end of described master calibration chi is set with a protractor, the opposite side of master calibration chi is carved with graduation mark, and the center of circle of described protractor is by rotating shaft hinged one secondary rule.
