Often need to draw arc, circle, concentric circles in study, the compasses drawing efficiency that tradition paints circle employing is low, concentric circles needs repeatedly to draw,
Error ratio is larger, and when drawing circular arc, radian is difficult to grasp, and is also inconvenient to alter.
A kind of entitled " Junior Mathematics drawing compass, Application No. 201520860982.1 " is disclosed in prior art
Patent, fixing leg is fixed, be rotatably connected bar, and two rotation legs with drawing pen are easy to once draw concentric circles, leads to
Overregulate and rotate the position of leg and can change the size of concentric circles, strong applicability, drawing efficiency are high, draw single arc or
During concentric arcs, using compareing for indicator in connecting rod and angle dial, it is easy to the connecting rod anglec of rotation is controlled, and then controls
Radian size processed, when arc is painted or circle error needs modification, the rotation leg with Correction brush is adjusted to appropriate location, the company of rotation
Error lines wiped by extension bar, not the used time by Correction brush raise, but the patent yet suffers from some problems：Due to pilot pin
Comparison is sharp, and the positioning function to paper is poor, when drawing pen is drawn, is easily caused sheet wander, causes at pilot pin when serious
Paper damage, affect attractive in appearance and drafting accuracy, and be not easy to find centre point again；The altering function of the patent is realized
When, need by with Correction brush rotation leg be moved to correspondingly sized altered, lose time, reduce drawing efficiency；
When circular arc is drawn, circular arc is drawn according to indicator, but as radian is easily drawn greatly by inertia, too slow the prolongation again of picture is drawn
Time, reduce drawing efficiency.
Content of the invention
In order to overcome the shortcomings of the presence of existing compasses, the utility model provides a kind of high efficiency drawing compass, can be right
Paper is positioned, and prevents paper from damaging, it is to avoid to affect the attractive in appearance of paper, is easy to reuse centre point, is improved drafting accuracy,
Correction process is convenient and swift with picture arc process, improves drawing efficiency.
The utility model solves the technical scheme adopted by its technical problem, a kind of high efficiency drawing compass, including fixed
