Abstract
The utility model discloses a protractor, which comprises a circular protractor body (1), wherein the inside of the circular protractor body (1) is provided with a zero-degree transverse ruler (2), one end of the zero-scale transverse ruler (2) is movably connected with an angle ruler (3), and the circular protractor body (1) is provided with scales. The protractor provided by the utility model has the advantages that the structure design is reasonable, the convenience in carrying and use is realized, the angle of the angle ruler of the protractor can be adjusted within 360 degrees, the application range is wide, the measuring result is accurate, one protractor with multiple purposes is realized, and the convenience and practicality are realized.
Description
Technical field
The utility model relates to a kind of measurement mechanism, is specifically related to a kind of protractor.
Background technology
Protractor of the prior art all is fixed angle, and measure different angles also needs a plurality of protractors.Applicability is relatively poor, and the measurement result accuracy is lower, therefore, necessary on the basis of prior art the design a kind of rational in infrastructure, easy to use, applicability is good, measurement result is protractor accurately.
Summary of the invention
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of reasonable in design to be provided, and easy to use, a chi is multiplex, and applicability is good, and measurement result is protractor accurately.
Technical scheme: in order to realize above purpose, the technical scheme that the utility model is taked is:
A kind of protractor, it comprises: the protractor body that goes in ring, in belt protractor body, be fixed with the zero degree crossfoot, and be connected with angle square at zero degree crossfoot one end, described belt protractor body is marked with scale.
As preferred version, above-described protractor, described belt protractor body are marked with the angle of 0 to 360 degree, can measure arbitrarily angledly, and measurement result is accurate, and is convenient applicable.
As preferred technical scheme, scale all is carved with in two of front and back on the protractor body that goes in ring, and is more applicable like this.
Beneficial effect: the protractor that the utility model provides has the following advantages:
The protractor that the utility model provides, reasonable in design, easy to use, the angle of the angle square of protractor can be adjusted in 360 degree, the scope of application is extensive, and measurement result is accurate, and a chi is multiplex, very convenient, practicality can overcome many deficiencies of the prior art.
