Abstract

The utility model provides a multifunctional ruler. The multifunctional ruler comprises ruler surfaces and a rotating shaft structure, wherein the ruler surfaces comprise an upper ruler surface and a lower ruler surface; scales on the upper ruler surface can be continued by the lower ruler surface; the upper ruler surface and the lower ruler surface are connected by the rotating shaft structure; the rotating shaft comprises an inner rotating shaft and an outer rotating shaft; the inner rotating shaft is connected to the lower ruler surface; the outer rotating shaft is connected to the upper ruler surface; the inner rotating shaft is provided with an dentoid convex capable of being embedded into a groove in the bottom of the outer rotating shaft; a certain angle can be formed by rotating the dentoid structure; and angle degrees are engraved on the surface of the outer rotating shaft. Compared with the prior art, the multifunctional ruler has the advantages that the operation is simple and feasible, the cost in low, and the drawing operation difficulty caused by the fact that during use, one side of a similar current angle ruler can not be in contact with a piece of paper, is solved.

Description

Multifunctional ruler

Technical field

The utility model relates to a kind of ruler, and especially a kind of have measurement simultaneously and draw the ruler of angle function, belongs to the stationery technical field.

Background technology

Ruler and set square all are the stationery of the daily frequent use of people, and ruler is used for measuring length, and set square is used for the picture angle, yet it is very inconvenient to carry so multiple ruler simultaneously, if can bring more facility will for people's life both combinations.

The utility model content

The purpose of the utility model embodiment is to provide a kind of ruler of measuring and making things convenient for the picture angle that has.

Technical solutions of the utility model are achieved in that

A kind of multifunctional ruler, it comprises chi face and pivot structure, described chi face is made up of last chi face, following chi face two parts, the scale of chi face is gone up in following chi face continuity, the described chi face of going up is connected by pivot structure with following chi face, described pivot structure is made up of interior rotating shaft and outer shaft, interior rotating shaft is connected with following chi face, outer shaft is connected with last chi face, in the rotating shaft detent projection is arranged in described, can be embedded in the groove of outer shaft bottom, and can rotate fixed angle by this dentalation, be carved with angle degree on the surface of outer shaft.

The utility model compared with prior art has the following advantages: the utility model embodiment is simple, and is with low cost, and a side chi face can not contact the mapping operation difficulty of paper when having solved existing similar bevel protractor and using.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the explosive view of the utility model embodiment.

The specific embodiment

Provide preferred embodiment of the present utility model below, these embodiment and unrestricted content of the present utility model.

Embodiment

As shown in Figure 1, a kind of multifunctional ruler, it comprises chi face and pivot structure, described chi face is made up of last chi face 1 and following chi face 2 two parts, on last chi face 1 and the following chi face 2 scale is arranged, the scale of chi face 1 is gone up in the scale continuity of following chi face 2, two chi faces can merge measurement length, and described chi face 1 and the following chi face 2 gone up is connected by pivot structure, and described pivot structure is made up of interior rotating shaft 4 and outer shaft 3, interior rotating shaft 4 is connected with following chi face 2, outer shaft 3 is connected with last chi face 1, in the described interior rotating shaft 4 detent projection is arranged, and can be embedded in the groove of outer shaft 3 bottoms, and can rotate fixed angle by this dentalation, be carved with angle degree 5 on the surface of outer shaft 3.During use, it is identical with general ruler to measure length method, and when drawing angle, only need rotate according to the number of degrees of angle degree 5 needs angle, along the interior angle setting-out of last chi face 1 and following chi face 2, can obtain corresponding angle again.

The utility model is not limited in above-mentioned embodiment, can not limit scope of the present utility model with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should be interpreted as belonging within the scope that the utility model patent contains.

Claims
