Problems solved by technology

[0002] Existing rulers, especially stationery rulers, are limited by portability factors, and the length is relatively short, usually 18-20cm for the maximum length. If you need to measure the length of a longer line segment, you need to divide it into multiple times, and errors are prone to occur
It is also particularly inconvenient when drawing longer length lines

Abstract

The invention provides a simple rotary folding ruler. The simple rotary folding ruler comprises a main ruler and an auxiliary ruler. One end of the main ruler is hinged to one end of the auxiliary ruler through a pin. The simple rotary folding ruler is characterized in that the main ruler is provided with a containing groove, and the length direction of the containing groove is parallel to the length direction of the main ruler; when the main ruler and the auxiliary ruler are in a folded state, the auxiliary ruler is stored in the containing groove; when the main ruler and the auxiliary ruler are in an unfolded state, the auxiliary ruler leaves the containing groove; the containing groove is provided with a downward exit and entrance, and the auxiliary ruler goes into or leaves the containing groove through the exit and entrance. According to the simple rotary folding ruler provided by the invention, as the main ruler is hinged to the auxiliary ruler, a user only needs to use the main ruler when a short line needs to be measured or drawn; when a long line needs to be measured or drawn, the user can unfold the auxiliary ruler to enable the main ruler to be flush with the auxiliary ruler, the whole length of the ruler is extended. Meanwhile, the requirement for portability of a ruler body is met, and the measuring or drawing precision is improved.

Description

technical field [0001] The invention relates to a simple rotary folding ruler. Background technique [0002] Existing rulers, especially stationery rulers, are limited by portability factors and are short in length, usually 18-20cm for the maximum length. If you need to measure the length of a longer line segment, you need to divide it into multiple times, and errors are prone to occur. It is also particularly inconvenient when drawing longer length lines. Contents of the invention [0003] The object of the present invention is to provide a rotary folding rule with simple structure. [0004] The above object is achieved through the following technical solution: a simple rotary folding ruler, including a main ruler and a sub-ruler, one end of the main ruler and one end of the auxiliary ruler are hinged together by a pin, and it is characterized in that: There is a storage groove, and the length direction of the storage groove is parallel to the length direction of the ma...
