Abstract
The invention discloses an extensible compass. The extensible compass comprises a compass head, a pencil stub, a fixed head, a first fixed compass leg, a second fixed compass leg, a first flexible compass leg, a second flexible compass leg, holes and fixing pins; the first flexible compass leg and the second flexible compass leg are provided with the plurality of holes respectively, wherein the holes are uniformly formed; each fixing pin penetrates a hole to be inserted into one of the holes formed in the first flexible compass leg or the second flexible compass leg to be fixed, wherein the holes are formed in the first fixed compass leg and the second fixed compass leg respectively; the bottom of the first flexible compass leg is provided with the pencil stub; the bottom of the second flexible compass leg is provided with the fixed head. According to the extensible compass, the fixing pins can be inserted into the different holes of the first flexible compass leg and the second flexible compass leg respectively to adjust the range of the compass so as to enable the size of a circle to be drawn to be within the suitable range and the extensible compass is a novel compass which is used in drawing.
Description
Technical field
The present invention relates to a kind of Telescopic compasses.
Background technology
At present, often will draw circle in the process of drawing, compasses are also generally used by people, but according to the difference of compasses range, people, when drawing different size circular, need the compasses using different model, such people just need to carry multiple compasses in the process of drawing, trouble very.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of Telescopic compasses of research and design, in order to solve now in the process of drawing, in order to the circle drawing different size needs the shortcoming of the compasses carrying multiple model.The technological means that the present invention adopts is as follows:
A kind of Telescopic compasses, comprising: compasses head, pencil stub, gland, fixed gauge leg one, fixed gauge leg two, moving compasses leg one, moving compasses leg two, hole and steady pin; Fixed gauge leg one and fixed gauge leg two is provided with below described compasses head, described fixed gauge leg one internal sleeve is provided with moving compasses leg one, described fixed gauge leg two internal sleeve is provided with moving compasses leg two, described moving compasses leg one and moving compasses leg two are provided with multiple evenly distributed hole, described steady pin injects the hole internal fixtion on moving compasses leg one and moving compasses leg two through the perforate on fixed gauge leg one and fixed gauge leg two, be provided with pencil stub bottom described moving compasses leg one, bottom described moving compasses leg two, be provided with gland.
Be draw point as preferred described gland.
Rubber sleeve is had as preferred described compasses head top cover.
Compared with the prior art, a kind of Telescopic compasses of the present invention, the range ability regulating described compasses in moving compasses leg one hole different with moving compasses leg two can be inserted according to steady pin, allow the size of the circle wanting to draw in optimal range ability, allow people not need to carry the compasses of multiple model in the process of drawing, for people bring many convenient, structure is simple, modern design is the novel bow compass used in a kind of picture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of Telescopic compasses, comprising: compasses head 2, pencil stub 9, gland 1, fixed gauge leg 1, fixed gauge leg 24, moving compasses leg 1, moving compasses leg 26, hole 7 and steady pin 8, fixed gauge leg 1 and fixed gauge leg 24 is provided with below described compasses head 2, described fixed gauge leg 1 internal sleeve is provided with moving compasses leg 1, described moving compasses leg 1 can move up and down in fixed gauge leg 1, described fixed gauge leg 24 internal sleeve is provided with moving compasses leg 26, described moving compasses leg 26 can move up and down in fixed gauge leg 24, by regulating the length of moving compasses leg 1 and moving compasses leg 26, regulate the range ability of described compasses, people is allowed to want the size of the circle of picture in optimal range ability, people is allowed to draw in round process more convenient, described moving compasses leg 1 and moving compasses leg 26 are provided with multiple evenly distributed hole 7, described steady pin 8 injects hole 7 internal fixtion on moving compasses leg 1 and moving compasses leg 26 through the perforate on fixed gauge leg 1 and fixed gauge leg 24, pencil stub 9 is provided with bottom described moving compasses leg 1, gland 1 is provided with bottom described moving compasses leg 26, described gland 1 described compasses can be fixed on want draw paper on.Described gland 1 is draw point.Described compasses head 2 top cover has rubber sleeve, and rubber sleeve can increase the frictional force with staff, allows people well take and uses described compasses.
During use, pull up steady pin 8, according to the size of circle wanting picture, determine the length of optimal rule leg, determine the length that moving compasses leg 1 and moving compasses leg 26 stretch out, plug steady pin 8 and fix, can use, draw the circle of the size oneself wanting picture.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
