Technical Field

[0001] The utility model relates to the field of book binding clips, in particular to a convenient and adjustable book binding clip. Background Art

[0002] With the continuous development of education and publishing industries, books, as an important carrier of knowledge dissemination, are also being read, used and preserved in a constantly improving way. In order to better serve students, teachers and reading enthusiasts, book binders are used as an auxiliary tool to effectively fix book pages, making it easier for students to write and read, and preventing books from sliding or moving.

[0003] Existing portable adjustable book binders usually use bolts to fix books. The bolts are passed through the books and tightened at the bottom of the binder by punching holes in the books to fix the books. Some portable adjustable book binders use bolts to threadedly connect with threaded holes in connecting blocks to change the distance between two sets of binders to clamp books of different lengths.

[0004] On the one hand, the existing bolt-fixed books do not have an effective way to fix books, and cannot be clamped and fixed according to books of different thicknesses. Students are easily affected by the sliding of books when writing, resulting in a decrease in writing quality. On the other hand, the existing bolt-fixed binding clip distance change is relatively unstable, and the adjustment method is relatively cumbersome. It is necessary to replace different threaded holes by rotating the bolts within a range for fixing. Therefore, a convenient adjustable book binding clip is proposed to solve the above problems.
