Abstract

The invention discloses a multifunctional straight scale which comprises a straight scale, wherein scale lines are marked on the upper top end of the straight scale, and the bottom end has no scale lines; and the multifunctional straight scale further comprises an angle measuring scale face of 180 degrees, wherein an intermediate point of one end of the scale face without the straight scale lines is served as the original point marked on the straight scale. The multifunctional straight scale integrating a protractor and the straight scale has the functions of measuring the length and measuring the angle; and the multifunctional straight scale has a simple structure, is convenient to carry, and is practical.

Description

Technical field [0001] The invention relates to a school article, in particular to a multifunctional ruler. Background technique [0002] In daily learning, various measuring tools such as protractors and rulers are often used. Students often have a lot of confusion. For example, due to the wide variety of measuring tools, they often need to carry many middle measuring tools, which take up a lot of space. In addition, it is very inconvenient to change the measuring tools frequently during the use process; moreover, it is easy to forget one or more of them during the process of cleaning up the tools, etc., which brings a lot of inconvenience to the students' learning. Summary of the invention [0003] In view of the above-mentioned problems, the purpose of the present invention is to provide a multifunctional straightedge, which combines the straightedge and the protractor, with a simple structure and convenient use. [0004] The purpose of the present invention is achieved through ...
