Abstract
The utility model relates to a drawing tool, in particular to a compasses ruler with retractable functions. The retractable compasses ruler comprises a pencil, a ruler, a fixed head, a rail groove and a fixed nail, wherein the fixed nail is arranged at one end of the rail groove and the ruler is arranged in the rail groove; one end of the ruler is provided with the pencil and the other end is provided with the fixed head; the rail groove is matched with the ruler; the fixed head can be fixed at any position of the rail groove; and scales are arranged on the ruler. The retractable compasses ruler has a simple structure and is convenient to operate, use and carry. The compasses and the ruler are integrated, so that the ordinary compasses ruler has double functions.
Description
Technical field
The utility model relates to a kind of drawing tool, is specially a kind of compasses chi with Telescopic.
Background technology
Compasses are to be used for the instrument of draw circles or string in mathematics and drawing, are usually used in construction with ruler and compasses.Common compasses make normally metal, comprise that two parts (two legs) form, connect by a hinge in the middle of it, its hinge is with adjusting the mapping radius.General compasses are made of nib, rotating shaft, compasses supporting leg, lattice chi, hinged joint, handwriting, nib, compasses point, microtia, it is configured to: the upper end that is connected handwriting is inserted in the lower end of nib, the lower end of handwriting is threaded in the upper end of nib, the concordant end of microtia is welded in the middle of the outside of compasses supporting leg, and the lower end of compasses supporting leg clamps the upper end that is connected the compasses point.
As can be known, present metal compasses structure is a more complicated from above-mentioned description.Because thereby complex structure causes the probability that in use there was a mechanical failure also can increase relatively.
Summary of the invention
In order to solve the above problems, the purpose of this utility model provides a kind of compasses chi simple in structure, thereby solves the common metal compasses problem that in use there was a mechanical failure easily.
To achieve the above object, the utility model has adopted following technical scheme: a kind of telescopic compasses chi, comprise pencil, ruler, fixing head, rail groove, staple, and described rail groove one end is provided with staple, and its inside is provided with ruler; Ruler one end is provided with pencil, and the other end is provided with fixedly head.
Above-mentioned rail groove and ruler are complementary; Fixing head can be fixed in the optional position of rail groove.
Above-mentioned ruler is provided with scale.
The beneficial effects of the utility model: simple in structure, easy to operate, use light, be easy to carry.Compasses and chi two unifications make common compasses chi have dual-use function.

1-pencil among the figure, the 2-ruler, 3-is head fixedly, 4-rail groove, 5-staple.
The specific embodiment
Below in conjunction with accompanying drawing 1-2 the specific embodiment of the present utility model is made a detailed explanation.
Embodiment: a kind of telescopic compasses chi, comprise pencil 1, ruler 2, fixing 3, rail groove 4, staple 5, described rail groove 4 one ends are provided with staple 5, and its inside is provided with ruler 2; Ruler 2 one ends are provided with pencil 1, and the other end is provided with fixing 3.Being embedded in ruler 2 by rail groove 4, is the center with staple 5, and pencil 1 is the mode of mapping radius end, realizes mapping compasses function.
Described rail groove 4 is complementary with ruler 2; Fixing 3 optional position that can be fixed in rail groove 4.
Described ruler 2 is provided with scale.
According to reality mapping situation, can carry out Expansion ruler 2 in rail groove 4 by the scale on the ruler 2, fix by fixing 3 then, finish fixing after, by being that the center of circle is rotated and can maps with staple 5.
