Abstract

The utility model discloses an easy-grabbing drawing ruler which relates to a set of stationery. The easy-grabbed drawing ruler comprises a ruler body which is prism-shaped wholly. Furthermore three side surfaces of the prism are arc surfaces which respectively have a higher middle part and two lower side edge parts and project outwards. Each side surface is respectively engraved with length scales in different systems of unit. The grabbing and movement of the easy-grabbing drawing ruler on paper surface are very flexible and convenient in drawing. Furthermore the rulers of the most-commonly used systems of unit are integrated in one product. The easy-grabbing drawing ruler furthermore has the following advantages: reduced occupied volume, facilitated carrying and no easy losing.

Description

A kind of drawing rule of easy extracting

Technical field

The utility model relates to a kind of stationery, relates in particular to a kind of drawing rule of easy extracting.

Background technology

For the frequent people who needs drawing, chi is absolutely necessary, but present chi all is a rectangular plate shape thing, it simultaneously is affixed on the paper during drafting, it is very inconvenient to cause grasping the attachable mechanical stage period of the day from 11 p.m. to 1 a.m like this, often have to reach the purpose of adjusting mobile ruler by directly it being slided to move on paper, ruler slip on paper causes the lines of drafting just destroyed probably, and front work is all destroyed; In addition, often need to draw the length of the different system of units in the drawing course, as the International System of Units, Chinese Chinese system of weights, English unit commonly used, therefore the footage amount that wherein comprises the most frequently used chi of cover may be a lot, carry very inconveniently, and easily make and lack corresponding chi temporarily and influence carrying out smoothly of work because lose.

The utility model content

At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of drawing rule of easy extracting, and it grasps mobile flexible when drawing on paper, and the chi of the most frequently used system of unit can be integrated on the product, reduce to take volume, be convenient for carrying, and be difficult for losing.

The technical solution of the utility model is: a kind of drawing rule of easy extracting, comprise the ruler body, described ruler body integral body is a triangular prism shape, and three sides of triangular prism are the low outwards arcwall face of protuberance of high two inclines in middle part, and described each side is carved with the length scale of the different system of units respectively along incline.

The beneficial effects of the utility model are: when ruler was positioned on the paper naturally, because its side is curved, its two incline was higher than paper naturally, grasped mobile very convenient; During use incline being resisted against paper can use as common ruler; Each side is scribed the scale of the different system of units respectively on the triangular prism, satisfies the different needs of drawing.
