Abstract

The utility model discloses a ruler. The ruler comprises a ruler body, wherein a positioning hole is formed in the ruler body; a positioning shaft with a tip at the bottom is positioned and mounted in the positioning hole; and a plurality of small through holes are formed in the ruler body. The positioning shaft and the small through holes are formed on the ruler body, and a circle can be drawn by taking the positioning shaft as a center and the space between the small through holes and the positioning hole as radius, so that the ruler has the function of a compass, and is convenient to carry and applicable to rulers.

Description

A kind of ruler

Technical field

The utility model relates to study article, refers to particularly a kind of ruler.

Background technology

Before the utility model proposes, in the picture operation process, can often be used alternatingly ruler and compasses.But because the size of ruler and compasses is all larger, so very inconvenient when ruler and compasses are used alternatingly.And instrument required during the picture operation is more, and ruler and the compasses drawing tool that often is absolutely necessary so must carry simultaneously ruler and compasses, like this, carries extremely inconvenience.

The utility model content

The purpose of this utility model is the deficiency that exists in order to solve the above-mentioned background technology, proposes a kind of easy to carry and possess the ruler of calipers function.

For achieving the above object, the ruler that the utility model is designed comprises the chi body, and described chi body is provided with locating hole, and in described locating hole, the location is equipped with the bottom with the locating shaft of tip, and described chi body is provided with several small through hole.By add locating shaft and small through hole on the chi body, centered by locating shaft, can the picture circle take the spacing of small through hole and locating shaft as radius, make this ruler possess the function of compasses and easy to carry.

In such scheme, described locating hole and small through hole are arranged on described chi body in proportion.

In such scheme, described locating hole and small through hole equidistantly corresponding described chi body scale are evenly arranged, and described locating hole is arranged in 0 scale position of chi body.

In such scheme, described spacing is 1 ~ 10mm.

The utility model has the advantage of: by add locating shaft and small through hole on the chi body, centered by locating shaft, can the picture circle take the spacing of small through hole and locating shaft as radius, make this ruler possess the function of compasses and easy to carry.

Description of drawings

Fig. 1 is the structural representation of embodiment;

Fig. 2 is the position relationship structural representation of locating shaft, locating hole and small through hole.

In figure: chi body 1, locating hole 2, locating shaft 3, small through hole 4.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

Embodiment: a kind of ruler as shown in Figure 1, comprise chi body 1, chi body 1 is provided with locating hole 2, and locating hole 2 interior location is equipped with the bottom with the locating shaft 3 of tip, and chi body 1 is provided with several small through hole 4.By add locating shaft 3 and small through hole 4 on chi body 1, centered by locating shaft 3, can the picture circle take the spacing of small through hole 4 and locating shaft 3 as radius, make this ruler possess the function of compasses and easy to carry.

Above-mentioned locating hole 2 and small through hole 4 are arranged on chi body 1 in proportion.Equidistant corresponding chi body 1 scale of locating hole 2 and small through hole 4 is evenly arranged, and locating hole 2 is arranged in 0 scale position of chi body 1.Spacing is 1 ~ 10mm.

Above-mentioned chi body 1 can be namely ruler, can be also set square or protractor etc.

When the utility model uses: at first, locating shaft 3 is inserted in locating hole 2; Then, find small through hole 4 corresponding on chi body 1 according to required radius; At last, the nibs such as pencil are inserted in the small through hole 4 find, and pinned locating shaft 3, draw the circle of required radius centered by namely can locating shaft 3.

The utility model is by add locating shaft 3 and small through hole 4 on chi body 1, centered by locating shaft 3, can the picture circle take the spacing of small through hole 4 and locating shaft 3 as radius, and make this ruler possess the function of compasses and easy to carry.

The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
