CN205220160U - Ruler of mark equal space line fast - Google Patents

Abstract

The utility model relates to a stationery field specifically is the ruler of mark equal space line fast, including rack saw limit and sharp scale limit. The profile of tooth on rack saw limit is 90 right angles, and the tooth is 1 centimetre with the interval of tooth, straight line scale edge sets up a millimeter scale mark. Its characterized in that: the central authorities department on rack saw limit sets up horizontal reference line, is equipped with 1 centimetre long bisection scale mark at horizontal reference line's left end, and the right -hand member is equipped with 1 centimetre long trisection scale mark. During the operation, with horizontal reference line and draw good straight line and aligns, then continuous or be interrupted the equal space line that different intervals can be drawn out to the mark line segment along the rack saw with the side. The utility model discloses make drawing equal space line or form link up more with swift, convenient operation, low cost is suitable for and uses widely.

Description

Can the ruler of Fast Labeling equal space line

Technical field

The utility model relates to field of stationery, is specially a kind of ruler.

Background technology

At present, conventional ruler is of a great variety, but mostly only has simple scale, for measuring shorter distance or drawing straight line.In daily life with work, usually need to draw a large amount of forms by ruler, marking equal space line is then the main operation of drawing form, but uses common ruler with reference to tick marks equal space line, not only takes eye, also time-consuming.

Summary of the invention

The technical problems to be solved in the utility model is, provide a kind of can the ruler of Fast Labeling equal space line, and low cost of manufacture, easy to use.For head it off, the technical solution adopted in the utility model is: can the ruler of Fast Labeling equal space line, and comprise rack saw limit and slide-rule dial limit, the profile of tooth on described rack saw limit is 90 ° of right angles, and the spacing of tooth and tooth is 1 centimetre; Slide-rule dial limit arranges a millimeter graduation mark.The utility model is characterized in that: the centre on rack saw limit arranges horizontal reference line, is provided with the bisection graduation mark of 1 centimeter length at the left end of horizontal reference line, and right-hand member is provided with the trisection graduation mark of 1 centimeter length.During operation, by horizontal reference line and drawn aligned, then along rack saw same side continuously or be interrupted the equal space line that mark line segment can draw out different spacing.

The utility model advantage is: change on original ruler and establish a rack saw limit, provide a kind of can the form of Fast Labeling equal space line.The utility model makes drafting equal space line or form more coherent and quick, easy to operate, with low cost, is suitable for promoting the use of.

Detailed description of the invention

As shown in Figure 1, a kind of can the ruler of Fast Labeling equal space line, comprise rack saw limit 11 and slide-rule dial limit 12, the profile of tooth on described rack saw limit 11 is 90 ° of right angles, and the spacing of tooth and tooth is 1 centimetre; Slide-rule dial limit 12 arranges a millimeter graduation mark.The centre on described rack saw limit 11 arranges horizontal reference line 13, is provided with the bisection graduation mark 14 of 1 centimeter length at the left end of horizontal reference line 13, and right-hand member is provided with the trisection graduation mark 15 of 1 centimeter length.During operation, by horizontal reference line and drawn aligned, the same side continued labelling line segment then along rack saw can draw out the equal space line that spacing is 1 centimetre; With the origin or beginning of the equal space line of 1 centimetre for baseline, alignment bisection graduation mark 14, then mark line segment to the right continuously along the same side of rack saw, the equal space line that spacing is 0.5 centimetre can be drawn out; Equally, with the end of the equal space line of 1 centimetre for baseline, alignment trisection graduation mark 15, then mark line segment left continuously along the same side of rack saw, the equal space line that spacing is 1/3 centimetre can be drawn out.In addition, the side spaced markings line segment along rack saw then can draw out the equal space line that spacing is 2 centimetres.
