Description

Multifunctional compass

Technical field

The utility model relates to a kind of drawing instrument, especially a kind of compasses.

Background technology

When the student draws, waste time because of drawing instruments such as compasses, ruler are uneven sometimes.China's utility model patent once disclosed a kind of multifunctional compass No. 01250136.0, this multifunctional compass has leg and handle, leg links to each other with handle, on two legs of compasses, be provided with loose slot, in this loose slot, be set with ruler, thereby can utilize this ruler to measure required data.Like this, just need not determine the chord length of circle during drawing by other measurer.But, with regard to this multifunctional compass, the position of set ruler is comparatively fixing, and with the rule pin mutual interference mutually of compasses, be not easy to utilize separately ruler to draw straight line or measurement size, simultaneously, compare with traditional compasses, the overall structure change of product is bigger, need on the rule pin, offer loose slot or the like, it is complicated that manufacture craft is tending towards, and therefore, above-mentioned existing product exists defective.

The utility model content

The purpose of this utility model is that the ruler set-up mode to existing product improves, and provides a kind of flexible and convenient to use, is convenient to the multifunctional compass of processing and fabricating.

Multifunctional compass of the present utility model has handle, ruler and is arranged at the left and right rule pin of handle, at its lower end, and the upper end and the handle of left and right rule pin are hinged, and it is characterized in that an end of described ruler is hinged on the handle through hinge.In the process of using the utility model multifunctional compass, when allowing the free end (non-hinged end) of ruler, just can use these compasses normally to draw circle to horizontal direction or top skew; Simultaneously, because set ruler can freely be realized deflection around its jointed shaft with handle, so, just can utilize this ruler to draw straight line or measurement size easily, and can not be interfered because of the existence of advising pin.In addition, in the utility model, can also be on handle fixing rubber so that the user utilizes rubber to revise the mistake pen, like this, the function of compasses is also just more complete.When on handle fixedly during rubber, this rubber is embedded at the rubber holddown groove that is positioned at the handle top to good, this kind fixed form is convenient to from handle unload waste rubber, changes new rubber usually.

Compared with the aforementioned existing similar products, multifunctional compass of the present utility model has solved when the student maps on the classroom and has looked about apparatus, thereby the problem of losing time has to utilize to improve learning efficiency.Simultaneously, the adjustment of this multifunctional compass is simple, easy to use.Compare with traditional compasses, the manufacture craft of this multifunctional compass can't produce too big change, is convenient to processing and fabricating.Therefore, compasses of the present utility model will be welcome by the student more, more have practical value.

Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
