Description

Technical Field

[0001] The utility model relates to the technical field of teaching material auxiliary tools, in particular to a loose-leaf teaching material frame. Background Art

[0002] Teaching materials, also known as textbooks, are teaching books compiled according to curriculum standards and systematically reflect the subject content. They are mainly composed of catalogs, texts, exercises, experiments, charts, notes and appendices. Textbooks are the embodiment of curriculum standards. They are usually divided into units or chapters according to the school year or semester. Texts are the main part of textbooks and are an important indicator of the level of basic education in a country or region.

[0003] Currently, when loose-leaf textbooks are in use, traditional loose-leaf textbook frames mostly use positioning rings that open alternately to both sides in the middle. The joints of the positioning rings of this type of combination often have protrusions. When users turn the pages, the positioning holes of the textbook pages are easily scratched, which affects the positioning stability of the textbook and increases the risk of page damage.
