The compasses are reasonable in design, convenient to use and wide in application range and facilitates drawing diagrams, and the length of the compasses can be adjusted as required.

Description

A kind of compasses
Technical fieldThe utility model relates to a kind of drawing instrument.
Background technologyCompasses are drawing instruments that people use always, but existing compasses are relatively simple for structure, and function is also single relatively, can not satisfy people's demand.
Summary of the inventionThe purpose of the utility model has provided a kind of graphing of being convenient to, and is easy to use, can regulate the compasses of length as required.
The utility model comprises fixed bar, motion bar and holds handle; Rotating shaft is connected fixed bar on the top with motion bar, and the fixed bar low side is provided with locking pin, and the motion bar bottom is provided with the pen cap; Be provided with drawing pen in it; Fixed bar and motion bar are the nested type Collapsible structure, are provided with flexible connection piece between the two, motion bar surface rendering length scale.
After adopting said structure; People can utilize it to draw various circles or circular arc, can regulate the length of two bodies of rod as required, can also be according to the drawing needs kind of change-fountain pen more; Utilize the length scale to measure; The flexible connection piece that stretches between two bodies of rod can play both angles of adjusting, prevents that start point is excessive, the phenomenon that can't set back fast.
The utility model compared with prior art has following advantage: reasonable in design, be convenient to graphing, and easy to use, can regulate length as required, applied widely.
