Abstract

The utility model provides a drawing tool ruler which comprises a hollow housing. The housing is equipped with a chute, and a push button is arranged in the chute. The push button is connected with a protractor via a push button connecting piece. The protractor rotates about a rotary shaft. Only by using the drawing tool ruler, a drawing worker can successively draw a broken line with a needed angle. The drawing tool ruler is easy to operate and convenient to use.

Description

Drawing instrument chi

Technical field

The utility model relates to stationery, relates in particular to a kind of drawing instrument chi.

Background technology

In daily drawing performance, engineering staff need to draw the broken line of a large amount of straight lines, fixed angle.Under the condition of existing drawing instrument, illustrator need use ruler and bipod simultaneously, and it could draw the broken line of certain angle smoothly.

Utility model content

The purpose of this utility model is to provide a kind of ruler drawing straight line that uses easily, has the drawing instrument chi that protractor is determined the function of angle simultaneously.For this reason, the utility model adopts following technical scheme:

The utility model comprises hollow casing, and described shell is provided with chute, in described chute, is provided with push button, and described push button is connected by push button connector with protractor, and described protractor rotates round rotating shaft.

The utility model compared with prior art has the following advantages: only use the utility model, drawing personnel can draw required angle broken line smoothly, simple to operate, easy to use.

Accompanying drawing explanation

Fig. 1 is decomposing state structural representation of the present utility model;

Fig. 2 is assembled state structural representation of the present utility model;

Fig. 3 is use status architecture schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

With reference to accompanying drawing, with reference to accompanying drawing, the utility model comprises push button 1, chute 2, hollow casing 3, push button connector 4, protractor 5, rotating shaft 6.

The utility model provides a kind of drawing instrument chi, utilizes the protractor of the rotation of its inside, and user can use this chi broken line of certain angle of painting smoothly, and does not need to be used alternatingly ruler and protractor.

The utility model comprises hollow casing 3, and described shell 3 is provided with chute 2, in described chute 2, is provided with push button 1, and described push button 1 is connected by push button connector 4 with protractor 5, and described protractor 5 rotates round rotating shaft 6.

Described chute 2 is positioned at drawing rule inside, and described push button 1 is in the interior slip of chute 2, and on push button 1, part is exposed on chute 2, facilitates hand to promote.Push button 1 is stuck in chute 2 inside, and the friction by between the two fixes, and push button 1 below and protractor 5 link by connector 4.Described protractor 5 rotates round rotating shaft 6.Described protractor 5 is tangent with shell 3 surfaces, with push button 1 interlock, can in shell 3, stretch out the angle consistent with push button 1 indication angle, and protractor 5 can rotate to an angle around rotating shaft 6.Described rotating shaft 5 is fixedly connected in hollow casing 3 inside with protractor 5, as the center of rotation.

By the convenient definite required angle of broken line of rotary protractor 5.User's drawing pen can be drawn broken line smoothly unimpededly, saves the troublesome operation that is used alternatingly ruler and protractor.

The utility model adopts all-plastic material, wherein hollow casing 3 part surface polishings.The utility model, by structural design cleverly, combines ruler and protractor, makes the utility model have both functions concurrently, only uses this drawing rule, the drawing personnel required angle broken line of can painting smoothly.Simple to operate, easy to use, fashion handsome in appearance, Form and function perfect adaptation.

The utility model is not limited in above-mentioned embodiment, can not limit scope of the present utility model with this, the equivalence done according to the utility model claim and description changes and modifies, within all should being interpreted as belonging to the scope that the utility model patent contains.
