Problems solved by technology

[0002] In middle school teaching, students need to master the process of equal division of line segments. In addition, in reality, it is often necessary to use straight lines for equal division. This process is often processed by measurement and calculation methods. This process is cumbersome and complicated, and wastes time.

Abstract

The invention discloses a line segment equalizer, which comprises a sliding rod, a chute is provided on the sliding rod, a slidable handle is installed in the chute, a rotatable positioning scale is installed on the handle, and the sliding rod is provided with There are several equally divided scale points. Able to use the principle of equal division theorem of parallel line segments, fix the positioning scale by rotating the positioning scale past the right end point of the line segment, then move the positioning scale to the left in parallel to the bisection point of the slider, draw a point at the intersection of the scale and the line segment, and obtain the line segment The device has a simple structure and is easy to use, and can quickly divide a line segment into several points without measurement, which provides convenience for teaching and practical use.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a line segment equalizer. Background technique [0002] In middle school teaching, students need to master the process of equal division of line segments. In addition, in reality, it is often necessary to divide straight lines into equal divisions. This process is often processed by measurement and calculation methods, which is cumbersome and time-consuming. Contents of the invention [0003] In view of the above defects or deficiencies, the object of the present invention is to provide a line segment equalizer; [0004] Technical scheme of the present invention is: [0005] A line segment equalizer, comprising a sliding rod, a chute is provided on the sliding rod, a slidable handle is installed in the chute, a rotatable positioning scale is installed on the handle, and several equal parts are arranged on the sliding rod. scale point; [0006] One end of the sliding ro...
