Problems solved by technology

[0002] At present, there are many types of drawing tools, each tool has a single function and is inconvenient to carry
At the same time, whether it is a middle school or an institution of higher learning, the surface of the desk is basically made of hardwood, and the compasses are impenetrable. When doing classroom exercises or extracurricular exercises, there will be limited space, messy drawing tools, difficulty in carrying and Inaccuracies caused by drawing, etc.
Especially when designing projects for majors related to design, not only do you need to draw straight lines, but also arcs, etc., and when drawing, there will be problems such as fixation and instability that will affect the quality of the drawing, and it is inconvenient to switch back and forth. Not only Affect learning efficiency, and may also cause uncomfortable posture, etc.
[0003]Compasses are an important tool for daily learning and drawing. The widely used traditional compasses have a herringbone structure, which consists of two legs, pen caps and brushes. When using traditional compasses When determining the arcs and circles drawn, you must rely on auxiliary drawing tools such as rulers, set squares, and protractors. The process is cumbersome and inconvenient to use

Embodiment Construction

[0029] In order to detailed the technical content of the invention, the purpose and efficacy will be described in detail below.

[0030] like Figure 1 to 3 As shown, the present invention provides a convenient sizes, mainly including a word feet 1, a circular turn rod mechanism 4, a telescopic rebound mechanism 2, a magnetic duty opener dial 7, a cardboard 3, a stubbound station 5, boss 6, the reference plate 13 and the clamping mechanism.

[0031] The cardboard 3 is placed in the lower left and bottom of the clamping sliding mechanism, respectively, and the synergistic action of the two is placed on the panel 13, and the first foot 1 and the panel 13 are closely closed. Tight drawings. The upper and lower ends of the first foot 1 are provided with a scale line, and there is also a plurality of angle meter dial 7, which can reduce the back-oriented reversal of the drawing tool, while also a better measurement angle. An example circular hole 21 having a commonly used diameter of 1 ...

Abstract

The invention provides a convenient ruler and compasses drawing tool and a using method thereof. The drawing tool comprises a straight ruler, a compasses rotating rod mechanism, a telescopic rebounding mechanism, a clamping and sliding mechanism, a protractor dial, a clamping plate, bosses, an anti-friction table and a drawing board. The straight ruler is placed on the drawing board through the clamping plate and the clamping and sliding mechanism, the straight ruler is provided with upper and lower scale lines, the protractor dial and example round holes, the two bosses are symmetrically arranged on the upper surface of the straight ruler, and the anti-friction table is placed between the two bosses. A groove is formed in the bottom of the straight ruler, and the compasses rotating rod mechanism is placed in the groove. The telescopic rebounding mechanism is connected with the compasses rotating rod mechanism and the straight ruler, and an arc can be drawn rapidly through the synergistic effect of the compasses rotating rod mechanism and the telescopic rebounding mechanism. The drawing tool can be more comprehensively suitable for drawing of any paper, space is saved, carrying is convenient, drawing is more convenient and versatile, and the function that one ruler has multiple purposes is achieved.

Description

Technical field [0001] The present invention relates to the field of drawing tools, and more particularly to a convenient sizes and usage methods. Background technique [0002] Currently, there are many types of existing drawing tools, and each tool function is cured, it is inconvenient to carry. At the same time, whether it is a middle school or college, the desk surface is basically made of hardwood boards, and the convention is tied, when classics or extracurricular exercises, there will be space, drawing tools are dispersed, carry difficulties and difficulties The problem caused by the drawing caused. Especially when the design-related majors are designed, not only the straight lines are needed, but also have the drawing of arc, etc., and when drawing, there will be fixed instability and other issues affect the quality of the drawing, it is not convenient to switch, not only Impact learning efficiency, it may also cause uncomfortable posture. [0003] The compliance is an imp...
