Problems solved by technology

[0002] At present, the scales used by students daily have scale lines on only one side of the scale body. When using it, the scale body needs to be turned back and forth, which is inconvenient to use; and the scale lines of the existing scales are composed of multiple lines of the same color. Long-term use will cause glare, which will easily lead to reading errors, visual fatigue, endanger the eyesight of users, especially young students, and cause myopia; the four corners of the scale are right angles, if you are not careful when using Injure the user or others, causing accidental injury
In addition, when using a scale to draw, it is necessary to use other drawing tools such as protractors and compasses at the same time, and the drawing efficiency is low

Abstract

A calibrated scale is provided with calibration tail and calibration number. The calibration tail is positioned on two sides of two faces of the scale, partial calibration tail is colourful, and four corner pins of the scale are round angles. One end of the scale is provided with ring angle slot, straight angle dividing slot and circular slot. Reciprocating turning of the scale is not needed when using the scale. The colour design is adopted for partial calibration tail to avoid glitz caused by long time use, alleviate eye tiredness, and make reading more convenient and faster. The other end of the scale is provided with ring angle slot, straight angle dividing slot and circular slot to make description more convenient and improve the description efficiency. The design of round angle for corner pin also improves safety in utilization.

Description

technical field [0001] The invention relates to a measuring tool for measuring length, in particular to a scale for direct reading and drawing. Background technique [0002] At present, the scales used by students daily have scale lines on only one side of the scale body. When using it, the scale body needs to be turned back and forth, which is inconvenient to use; and the scale lines of the existing scales are composed of multiple lines of the same color. Long-term use will cause glare, which will easily lead to reading errors, visual fatigue, endanger the eyesight of users, especially young students, and cause myopia; the four corners of the scale are right angles, if you are not careful when using Injure the user or others, causing accidental injury. In addition, when drawing with a scale, other drawing tools such as protractors and compasses need to be used at the same time, and the drawing efficiency is low. Contents of the invention [0003] The technical problem t...
