Abstract

The invention discloses a folding-type multifunctional measuring scale. The folding-type multifunctional measuring scale comprises a middle scale body, a first auxiliary scale body and a second auxiliary scale body, wherein a first end of the middle scale body is sunken to form a first connection part, and a second end of the middle scale body is sunken to form a second connection part; an end part of the first auxiliary scale body is sunken to form a third connection part matched with the first connection part, the first connection part is pivotedly connected with the third connection part through a first rotary shaft, and the first connection part and the third connection part oppositely move along the first rotary shaft when the middle scale body and the first auxiliary scale body are folded; an end part of the second auxiliary scale body is sunken to form a fourth connection part matched with the second connection part, the second connection part is pivotedly connected with the fourth connection part through a second rotary shaft, and the second connection part and the fourth connection part oppositely move along the second rotary shaft when the middle scale body and the second auxiliary scale body are folded; and length scales and angle scales are formed on at least the middle scale body. The folding-type multifunctional measuring scale disclosed by the invention enables the surfaces of the middle scale body, the first auxiliary scale body and the second auxiliary scale body to be level while being unfolded; and the folding-type multifunctional measuring scale has good marking and measuring effects.

Description

technical field [0001] The invention relates to a folding multifunctional measuring ruler. Background technique [0002] In daily life and study, rulers, protractors, and triangular rulers are often used. There are many types of rulers, but they have a single function, which is very inconvenient to use and not easy to carry. [0003] Although the folding ruler currently on the market solves the problem of portability, due to the thickness of the ruler body, the surface is not flush when folded, which affects the effect of marking and measuring. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a foldable multifunctional measuring ruler that is easy to make and easy to use, which can be used not only as a ruler, a triangle ruler, but also as a protractor. collision. [0005] In order to achieve the above technical effects, the present invention discloses a foldable multifunctional measuring ruler, comprising: [...
