Abstract

The utility model discloses a two-side angle rule. The two-side angle rule is related with a drawing tool and can draw a line with any accurate angle. The two-side angle rule adopts the technical scheme as follows: the two-side angle rule includes an angle needle rule and an angle measurement rule, wherein both the angle needle rule and the angle measurement rule include bigger strip rule bodies at the right ends as well as sharp parts and semi-circular angle measurer parts at the left ends; connecting holes are processed in the center of the angle measurer part of the angle measurement rule and near the sharp part of the angle needle rule; and the angle needle rule and the angle measurement rule are movably connected through a hollow rivet. The two-side angle rule is more suitable for complicated manual drawing operators to select and use.

Description

The both sides angle square

Technical field:

The utility model is relevant with drawing instrument, specifically is meant the both sides angle square.

Background technology:

Use various chi tools to draw and rule and in study and a lot of work, can't do without; In concrete operation; Often will be in the face of the angle of different angles complicated and changeable, the utilization hornwork measures the mode of afterwards ruling earlier more loaded down with trivial details, and the degree of accuracy also is difficult to guarantee; So people need a kind of simple operation, chi tool easy to use to come accurately to draw the figure line of the angle of various different angles; And the chi plate of extensively seeing does not possess this function, this to a great extent limit people's this needs, be necessary to improve.

Summary of the invention:

The purpose of the utility model is that a kind of both sides angle square is provided, and it can solve aforesaid problem.

Theing contents are as follows of the utility model technical scheme: it comprises angular pin chi, angle square; Said angular pin chi, angle square all comprise the tip shape part, the protractor part of semicircle shape of chi body and left end of the strip of the big half of right-hand member; Near the tip shape part of the center of circle of the protractor of angle square part and angular pin chi, all be processed with connecting hole, the two flexibly connects through tubular rivet.

The beneficial effect of the utility model is to draw arbitrarily the accurately figure line of angle.

Description of drawings:

Fig. 1 is the front view at 0 ° of angle of both sides angle square.

Fig. 2 is the front view at 60 ° of angles of both sides angle square.

Among the figure, 1 is the angular pin chi, and 2 is angle square, and 3 is tubular rivet.

The specific embodiment:

As shown in the figure; The design's both sides angle square comprises angular pin chi 1, angle square 2; Angular pin chi 1, angle square 2 all comprise the chi body of the strip of the big half of right-hand member, and the top all is processed with length graduation mark and numeral, and the left end of angular pin chi 1 is that the indicating section of tip shape, the left end of angle square 2 are the protractor part of semicircle shape simultaneously; Near the tip shape part of the center of circle of the protractor of angle square part and angular pin chi, all be processed with connecting hole; The two flexibly connects through tubular rivet 3, and as shown in the figure, angular pin chi and angle square can rotate around the tubular rivet of connection hole each other; The indicating section of tip shape can point to any position of 0 ° to 180 ° of protractor part; Like this, the operator draws the both sides at angle, (60 ° of angles for example) as shown in Figure 2 respectively again just can operating position that the both sides angle square makes the position, alignment angle tip, hole of the tubular rivet of its connection hole point out the top of the horn with nib when drawing the figure line of a certain angle through the chi body portion of strip; The part polishing that is interrupted of taking away the top of the horn that the connection hole is covered behind the angle square of both sides becomes complete angle to get final product, and so just can obtain accurately figure line at any angle.

Claims

1. both sides angle square; It comprises angular pin chi, angle square; It is characterized in that said angular pin chi, angle square all comprise the tip shape part, the protractor part of semicircle shape of chi body and left end of the strip of the big half of right-hand member; Near the tip shape part of the center of circle of the protractor of angle square part and angular pin chi, all be processed with connecting hole, the two flexibly connects through tubular rivet.
