Description
One, technical field
The utility model relates to a kind of set square with compasses function.
Two, background technology
General set square is made up of three limits, mostly is drawing square or 45 ° of drawing squares of 60 °, and there is the length graduation mark on the chi limit, only can be used for the picture straight line, or fixing angle line, function singleness.
Three, summary of the invention
The purpose of this utility model provides a kind of set square with compasses function.
The utlity model has the set square of compasses function, comprise a set square that has the length scale, be characterized in: on an angle of this set square, handle is set, handle the right angle flange is set on one side of right set square, the end of flange fixedly installs a pilot pin, this pilot pin is perpendicular to described flange, also offer a long hole shape slideway on the flange, slide block of embedding on the slideway fixedly installs a mobile picture pin on the slide block, this moves the picture pin perpendicular to described flange.
In the such scheme, the length scale is arranged on the described flange, described pilot pin is arranged on the starting point of length scale, is provided with on the described slide block and points out the scale tip, can directly measure radius like this and draw circle on set square.
In the such scheme, described mobile picture pin is made up of lead for retractable pencil and lead for retractable pencil clamping device, adopts lead for retractable pencil to make mobile picture pin, can be used for drawing drawing.
In the such scheme, two slotted holes that cross intersects are set on the chi plate of described set square, can draw graphed lines easily.
In the such scheme, on the described set square, connect a semicircular protractor on the another side wherein, can make protractor usefulness, further enlarge the function of use of set square.
The utility model is owing to be provided with the right angle flange with one side of set square, and mobile picture pin and pilot pin are set on the right angle flange, when set square is holded up, moving slider, determine the distance between mobile picture pin and the pilot pin, promptly determine the picture radius of a circle, hand-held handle can the picture circle.When set square is kept flat, still can make ruler and use.If on a limit of set square, connect semicircular protractor, can make protractor usefulness, further enlarge the function of use of set square.The new advantage of this practicality is: set square can be worked as compasses and be used.
