Abstract
The utility model relates to a double-duty compass, which is characterized in that a line adjustment knob is arranged on one foot of the prior ordinary compass, a flexible line is extended out of the lower end of the foot; one end of the flexible line is coiled on the line adjustment knob; while a point ringer is arranged at the tip of the other end of the flexible line; and a slip ring is positioned on the flexible line. The utility model has the advantages of simple structure, easy manufacturing process, convenient operation, ability to draw circle and ellipse, and improved productivity for drawing.
Description
The utility model relates to a kind of drawing tools, its body a kind of dual-purpose compasses of saying so.
Compasses are a kind of drawing tools commonly used, its function ratio of general compasses is more single, can only draw circle, when needing the figure of similar circles such as picture ellipse when us, often can only reduce operating efficiency like this with other way, there also have some multi-functional compasses to draw at present to be oval, as the patent No. is 95108842 disclosed a kind of compasses of drawing any size ellipse, but these compasses structures are complicated, and price is expensive.
The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of simple in structure, easy to use, price is low, can draw oval dual-purpose compasses.
For achieving the above object, the technical solution of the utility model is: establish a line transfer knob on a pin of existing common compasses, a flexible cord from then on lower end of pin stretches out, and an end of flexible cord is around on the line transfer knob, the termination of the other end is provided with a needle point collar, and flexible cord is provided with a slip ring.
Following picture is further described concrete structure of the present utility model in conjunction with the accompanying drawings.
Accompanying drawing is a front view of the present utility model.
Referring to accompanying drawing, the utility model comprises body 1, left foot 2, right crus of diaphragm 3, pilot pin 5, paintbrush 4, line transfer knob 6, flexible cord 7, slip ring 8, the needle point collar 9, described left foot 2 is provided with line transfer knob 6, one end of paintbrush 4 is a paintbrush, the other end is the location tip, and flexible cord 7 stretches out from the lower end of being located at the pilot pin 5 on the left foot 2, and an end of flexible cord 7 is around on the line transfer knob 6, the termination of the other end is provided with the needle point collar 9, and the flexible cord between the lower end of the needle point collar 9 and pilot pin 5 is provided with a slip ring 8.
The utility model using method is as follows: draw bowlder, its technique of painting and common compasses are just the same, when drawing ellipse, according to being that the track of the point of fixed length is oval definition apart from sum to two fixed points, can emit the line of respective length according to the size of drawn ellipse by line transfer knob 6, the needle point collar 9 is enclosed within the location tip of paintbrush 4, the location tip of pilot pin 5, paintbrush 4 is fixed as the AnchorPoint of ellipse, pencil is inserted slip ring 8, draw a circle with pencil pulling flexible cord 7, can be drawn as the ellipse of corresponding size.
In sum, the utility model is simple in structure, processing and fabricating is easy, easy to use, not only can draw circle but also can draw ellipse, can improve the operating efficiency of drawing.
