Abstract

The utility model relates to a drawing tool, and discloses a trilateral-shaped angle ruler which can draw lines of an acute angle of accurate degree. The trilateral-shaped angle ruler is characterized by comprising a fixed ruler, a movable ruler and a scaleplate; the fixed ruler and the scaleplate are combined in a V-shaped mode, the included angle of the fixed ruler and the scaleplate is fixed, the scaleplate is provided with angle scale mark from 0 degree to 90 degrees and figure identification, and the left end of the fixed ruler is movably connected with one end of the movable ruler through a rivet and a connection hole. The trilateral-shaped angle ruler is suitable for a worker drawing various complicated manual drawings to use.

Description

Three limit shape angle squares

Technical field:

The utility model is relevant with drawing instrument, specifically refers to three limit shape angle squares.

Background technology:

With various chi tools draw the line study and a lot of work in can't do without, in concrete operation, often will be in the face of the angle of different angles complicated and changeable, the mode that the utilization hornwork is measured first rear line is more loaded down with trivial details, the degree of accuracy also is difficult to guarantee, so people need a kind of simple operation, chi tool easy to use accurately to draw the figure line of the acute angle angle of various different angles, and the chi of extensively seeing possesses this function, this needs that this has limited people to a great extent are necessary to improve.

Summary of the invention:

The purpose of this utility model is that a kind of three limit shape angle squares are provided, and it can solve aforesaid problem.

Theing contents are as follows of technical solutions of the utility model: it comprises scale, moving chi, scale, described scale, scale are the v font combination that is fixed angle, be processed with 0 ° to 90 ° angle index line and Digital ID on the scale, be flexibly connected at the left end of the scale end by rivet and connecting hole and moving chi.

The beneficial effects of the utility model are that these three limit shape angle squares can be drawn arbitrarily the accurately acute angle figure line of angle.

Description of drawings:

Fig. 1 is the design's front view.

Among the figure, 1 is moving chi, and 2 is scale, and 3 is rivet, and 4 is scale.

The specific embodiment:

As shown in Figure 1, the design's three limit shape angle squares comprise scale 4, moving chi 1, scale 2, and wherein scale, scale are the v font combination that is fixed angle, and fixed angle is take 45 ° as best, scale is slightly long in addition, and the above is processed with 0 ° to 90 ° angle index line and Digital ID; Pass through the end flexible connection of rivet 3 and connecting hole and moving chi 1 at the left end of scale, as shown in the figure, can find corresponding calibration points at scale in any acute angle angular range of the moving chi of moving between 0 to 90 degree, can and move both sides and the angle that chi is drawn out required accurate angle by scale by this, straightforward.

Claims

1. limit shape angle square, it comprises scale, moving chi, scale, it is characterized in that described scale, scale are the v font combination that is fixed angle, be processed with 0 ° to 90 ° angle index line and Digital ID on the scale, be flexibly connected at the left end of the scale end by rivet and connecting hole and moving chi.
