Abstract

The utility model discloses a multifunction drawing instrument, which belongs to a drawing instrument or accessory, in particular the drawing instrument being capable of measuring length, angles and positioning horizontal lines. One side of a platelike body of the drawing instrument is provided with a dividing rule and the surface of the platelike body of the drawing instrument is provided with a circular and open semicircular protractor. The multifunction drawing instrument is structurally characterized in that a discontinuous circle drawing hole extends from the centre of a circle of the semicircular protractor on the body; the other side of the body, which is opposite to the dividing rule, is provided with a raised semicylindrical hand rest; and the top of the hand rest is provided with a leveler. By using the multifunction drawing instrument, straight lines can be drawn and the length can be measured, the angles and the horizontal lines can also be measured and circles with different radii can be drawn; moreover, the raised hand rest is arranged, and thus, functions are added, the cost is reduced, the use is convenient and the error is reduced.

Description

The multifunctional drawing utensil

Technical field

The utility model belongs to drawing appliance or annex, particularly the drawing appliance of energy measurement length, angle and position level line.

Background technology

Rule, protractor generally are the common tools of drawing, and also have to be grouped together, and often draw circle simultaneously; generally be to use compasses separately, the utensil number of packages of Zeng Jiaing is not easy to tidy up like this; general tabular drawing appliance all is plane now simultaneously, is not easy to move flexibly and fixer.

The utility model content

In order to overcome the deficiency of existing single-piece drawing appliance function singleness, the utility model provides a kind of multifunctional drawing utensil, and this multifunctional drawing utensil can not only be drawn straight line and measure length, can also take measurement of an angle and horizontal line, draws the circle of different radii.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of multifunctional drawing utensil, there are rule, surface to offer the semicircle protractor of circular open in drawing appliance plate-like body one side, its structure is: extend the picture circular hole of a discontinuity on body from the center of circle of semicircle protractor, the opposite side of the relative rule of body has the semicylinder hand rest of projection.

Above-mentioned multifunctional drawing utensil, its structure are at described hand rest top horizon equipment to be arranged.

The beneficial effects of the utility model are to extend the picture circular hole of a discontinuity on body from the center of circle of semicircle protractor, like this can be without just can draw the roughly circle of different radii of compasses; Simultaneously the opposite side of the relative rule of body has the semicylinder hand rest of projection, conveniently moves and firmly, increases the stability and the flexibility of drawing appliance, adds few error; Can also utilize the horizon equipment at hand rest top to measure horizontal line quickly, be convenient to picture horizontal linear or parallel lines.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model,

Among the figure, 1. body, 2. rule, 3. protractor is 4. drawn circular hole, 5. hand rest, 6. horizon equipment.

The specific embodiment

The specific embodiment of the present utility model is, as shown in the figure:

Embodiment 1, a kind of multifunctional drawing utensil, there are rule 2, surface to offer the semicircle protractor 3 of circular open in drawing appliance plate-like body 1 one sides, extend the picture circular hole 4 of a discontinuity on body 1 from the center of circle of semicircle protractor 3, the opposite side of body 1 relative rule 2 has the semicylinder hand rest 5 of projection.

Embodiment 2, a kind of multifunctional drawing utensil, there are rule 2, surface to offer the semicircle protractor 3 of circular open in drawing appliance plate-like body 1 one sides, on body 1, extend the picture circular hole 4 of a discontinuity from the center of circle of semicircle protractor 3, the opposite side of body 1 relative rule 2 has the semicylinder hand rest 5 of projection, at described hand rest 5 tops horizon equipment 6 is arranged.

Claims

1. multifunctional drawing utensil, there are rule, surface to offer the semicircle protractor of circular open in drawing appliance plate-like body one side, it is characterized in that: extend the picture circular hole of a discontinuity on body from the center of circle of semicircle protractor, the opposite side of the relative rule of body has the semicylinder hand rest of projection.

2. multifunctional drawing utensil according to claim 1 is characterized in that: horizon equipment is arranged at described hand rest top.
