Description
Technical field
The utility model relates to a kind of drawing stationery, especially a kind of Three point compass.
Technical background
Compasses are drawing tools that people use always, and the compasses on the market have a variety of, but owing to there are problems, bring inconvenience for people's use.For example: compasses mostly adopt lead for retractable pencil to draw, in case lead for retractable pencil fractures, not only waste but also the finger of can making dirty trouble and unhygienic; Most of compasses adopt bipod, need picture twice when drawing annulus, not only lose time but also the center of circle is located and forbidden; When measuring radius of a circle, also need to look for again separately rule.
Summary of the invention
At the problems referred to above, the utility model provides a kind of Triangle compasses, has satisfied people's needs.
The technical solution adopted in the utility model is: this Three point compass, comprise rotary handle and rule pin, and it is characterized in that: described rule pin has three, the middle fixing feet for band rule pin, the pin adjusted for band pencil fastener of both sides.
Be connected with rule on the described fixing feet.
After adopting said structure, when using compasses to draw annular, two pencils are separately fixed on the two side mark pin, once just two circles are drawn as, time saving and energy saving, and center of circle accurate positioning.If only draw a circle, only need with on the rule pin of a side fixedly pencil get final product.Rule on the fixing feet can take off, and both can be used for measuring radius, also can be used for the picture straight line to use.
The utility model has the advantages that: simple in structure, easy to use, time saving and energy saving, accurate positioning.
