Abstract

The invention relates to stretchable compasses. The stretchable compasses comprise a compass head, a fixing foot and a rotating foot; one end of the fixing foot is fixed to the compass head, one end of the rotating foot is hinged to the compass head, and the rotating foot is stretchable and is provided with a limiting device; and a pencil lead is arranged at the other end of the rotating foot. The compasses are easy to operate.

Description

Telescopic compasses
Technical field
The present invention relates to a kind of compasses, belong to novel office table separation.
Background technology
Compasses, in mathematics and drawing, are used to the instrument drawing circle or string, are usually used in construction with ruler and compasses.Compasses make material normally metal, be provided with two pin, upper end thereof, lower end can arbitrarily separate or close up, and to adjust the size of painted arc radius, the end of a pin is needle point, and the end of another pin can load paints pencil line or the line of ink marker.
But draw bowlder at the common compasses of use, need rotate with hand-held firmly compasses head and drive compasses head to draw a roundlet, not easy to operate, and easily cause firmly uneven and draw the situations such as askew.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of easy-operating compasses for the deficiencies in the prior art.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of Telescopic compasses, comprise compasses head, fixing feet and rotation pin, it is characterized in that: one end of described fixing feet is fixed on compasses head, one end of described rotation pin is hinged on compasses head, described rotation pin is scalable and be provided with stopping means, and the other end of described rotation pin is provided with lead for retractable pencil.
Being improved to technique scheme: described rotation pin is divided into top and bottom two parts, described top hollow, described lower end thereof is plugged in top and the other end is provided with lead for retractable pencil, and lower end, described top is provided with stop nut.
Being improved to technique scheme: the described rotation pin other end is provided with clip, and described clip side is provided with binding nut, and described lead for retractable pencil is folded on clip.
Being improved to technique scheme: described compasses head and fixing feet are located along the same line.
When the present invention uses, first rotation pin and fixing feet are separated by a distance, then fixing feet are vertically stood on paper, regulate and rotate pin length till rotation pin contacts with paper, tighten stop nut, then draw circle.
Beneficial effect of the present invention is:
During owing to using, fixing feet is vertical with paper all the time, user only need arrest compasses head and rotate, do not need to drive compasses head to move in a circle, easy to operate, and when using the active force that compasses are downward to be located along the same line with vertical fixing feet all the time and vertical with paper, the situations such as not easily generation picture is askew.
figure of description
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Embodiment
As shown in Figure 1, the Telescopic compasses of the present embodiment, comprises compasses head 1, fixing feet 2 and rotates pin 3, one end of fixing feet 2 is fixed on compasses head 1, rotating one end of pin 3 is hinged on compasses head 1, and it is scalable and be provided with stopping means to rotate pin 3, and the other end rotating pin 3 is provided with lead for retractable pencil 31.
Rotate pin 3 and be divided into top and bottom two parts, top hollow, lower end thereof is plugged in top and the other end is provided with lead for retractable pencil 31, and lower end, top is provided with stop nut 33.Rotate pin 3 other end and be provided with clip, clip side is provided with binding nut 32, and lead for retractable pencil 31 is folded on clip.Compasses head 1 and fixing feet 2 are located along the same line.
A kind of Telescopic compasses of the present invention is not limited to the various embodiments described above, and all employings are equal to the technical scheme of replacing and being formed, and all drop on the protection domain of application claims.
