Embodiment Construction

[0022] Please refer to Fig. 1, 2, drawing ruler of the present invention mainly comprises straight ruler 10, a parallel ruler 20 and a graduation ruler 30, wherein:

[0023] Straightedge 10 is the elongated ruler that one edge is provided with length dimension scale 11, and this straightedge 10 one end extends to the other end and forms a through groove 12, and the opening periphery of groove 12 is provided with groove length dimension scale 121, in addition An arc-shaped positioning groove 13 is formed on the bottom surface of the ruler 10 with one end of the groove 12 as the center point.

[0024] The parallel ruler 20 is an elongated ruler with a length scale 21 arranged on one edge, and the long side position of the parallel ruler 20 is provided with an assembly groove 22 penetrating from one side to the other side, so that the ruler 10 can be perpendicular to the parallel ruler 20 The movable assembly is connected in the assembly slot 22, so that the parallel ruler 20 can...

Abstract

The drawing rule includes one straight ruler, which has length scales, lengthwise groove from one end to the other and with length scales, and one ached locating slot around one of the groove end; one parallel ruler, which has length scales and one assembling slot from one side to the other for assembling the straight ruler movably onto the parallel ruler; and one semi-circular indexing ruler, which has angle scales, central notch and semi-circular lug around the central notch for the movable connection between the indexing ruler to the straight ruler. The drawing rule in the said structure is suitable for drawing parallel lines, vertical lines and various drawings.

Description

Technical field: [0001] The invention relates to a drawing tool, in particular to a drawing ruler which combines the functions of different scales such as a graduated ruler, a ruler and a parallel ruler to draw various lines. Background technique: [0002] Currently common drawing tools such as rulers, graduated rulers, and triangles are mainly used to assist users in drawing various lines. In the process of using these drawing tools to draw different lines, the following problems are likely to occur: [0003] 1. When the user wants to draw an oblique line with an angle, it is necessary to pre-define the two endpoints of the oblique line with a graduated ruler, and then use a ruler to connect the two endpoints to draw an oblique line with an angle. However, the aforementioned drawing method must be used alternately with a graduated ruler and a ruler, which causes a lot of inconvenience in drawing. [0004] 2. When the user wants to draw parallel or perpendicular lines to cr...
