Description
Technical Field
The utility model belongs to the technical field of stationery and specifically relates to a loose-leaf coil book.
Background
Loose-leaf notebooks, one of the most commonly used stationery items in everyday work and learning, are composed of a cover, a coil or binder, and inner leaves. The biggest difference with the common notepad is that the loose-leaf notebook is more flexible to use, and the inner pages (inner cores) can be taken out at will or rearranged and combined, thereby being convenient to arrange.
The coil of the loose-leaf coil is generally made of metal, an opening is formed in the loose-leaf coil for disassembling the inner leaf, and the opening is in a closed state due to the elastic deformation capacity of the metal, so that the inner leaf is opened by the acting force generated by the inner leaf when the inner leaf is disassembled by pulling the inner leaf, and the inner leaf is separated from the opening. However, the inner leaf is too forcefully violent when pulled or is often torn when the inner leaf is thin, so that the inner leaf cannot be taken out perfectly, and therefore, the pulling force for pulling the inner leaf needs to be increased a little bit when the inner leaf is detached, the inner leaf needs to be carefully tried out until the inner leaf is taken out perfectly, which is troublesome and inconvenient to use.
