Description

Multifunctional safety compasses device

Technical field

The present invention is relevant for a kind of compasses device, especially finger is a kind of can conveniently draw circle, and can make lines evenly and avoid stinging the broken face, stab hand, and further have and draw multifunctional safety compasses device fan-shaped, that measure circular radius and diameter, take measurement of an angle and be used as ruler use etc.

Background technology

As everyone knows, traditional compasses structure mainly includes a positioning rod and the line drawing bar that the top is articulated, the bottom of this backstay and line drawing bar is respectively equipped with a needle set and a tool, needle set puncture with this backstay bottom is positioned on the paper as the center of circle when circular and draw, and then 360 degree application of force turn line drawing bars, make a tool of this line drawing bar bottom on paper, draw circle.Yet, because traditional compasses are located as the center of circle with the puncture of needle set, its centralized positioning application of force of painting bowlder always forms a pin hole hole with center of circle puncture, even thorn damage destruction paper, and this pin hole hole or disrepair phenomenon are more obvious when drawing several concentric circles; Moreover, the tradition compasses are being painted this line drawing bar of turn that bowlder need carry out 360 degree, because the week circle turn application of force is difficult to equilibrium, adding this line drawing bar may change relative position with the application of force, and it is crooked often to make that lines are drawn as, or makes lines inhomogeneous, or the head and the tail lines can't correspondingly engage, or can't once plot and need revolve for several times and paint operation, repeatable operation or the like, quite inconvenience and not tool draw efficient, this deficient phenomena is to the general especially puzzlement of school-ager; And, its sharp-pointed needle set of tradition compasses also has potential danger, on taking, operating slightly once accidentally very easily stabbing hand, what is heard is arranged when making accident that the school-ager stabbed by compasses also, obvious, the tradition compasses really have necessity of positive improvement for the school-ager and the nonideal sired results tool of painting.

Again, the function singleness of tradition compasses, only can be as the drafting of circle, and can't carry out various fan-shaped draftings or the use of drawing as the ruler straight line, also can't be further used as measurement facility, for example measurement of the measurement of circular radius and diameter, angle etc. makes its functional limit of comparatively arresting, and nonideal drawing tool design, necessity of being improved is in the lump also arranged.Therefore, how at the clear improvement in addition of disappearance problems such as its operational inconvenience of traditional compasses, efficiency and danger, really be the emphasis direction that industry or the scholar that intelligence is arranged should be probed into, break through.

In view of not attaining the desirable fact on its operational many disappearance of traditional compasses and the structural design thereof, this case inventor is based on the cordiality of creating in the experience and the invention of school study, set about researching and developing its solution, hope can be developed a kind of convenience, security and functional multifunctional safety compasses device of having more, be all the student of learning phase with service, satisfy through for a long time design, test and study and generation of the present invention arranged.

Summary of the invention

The object of the present invention is to provide a kind of multifunctional safety compasses device, it can make, and to draw circular operation quite simple and easy, convenient and have efficient, and make the lines of drawing evenly reach the corresponding joint stable unanimity of lines, the results of learning that performance is got twice the result with half the effort, and then thoroughly improve, solve the pupil and paint the operational puzzlement of circle.

A further object of the present invention is to provide a kind of multifunctional safety compasses device, it can make circular drafting can not form pin hole hole on the paper, also exempt to deceive spinosity and decrease the phenomenon of destroying paper, and it is taken and draws in the operation has splendid security, and the contingency that can actively avoid stabbing produces.

Another purpose of the present invention is to provide a kind of multifunctional safety compasses device, it can expand the multiple function of use of compasses instrument, comprise that fan-shaped drafting is used, tolerance or measure is used and as the ruler use etc., enables to give better functional and promote its surcharge person.
