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) of the loose-leaf notebook can be taken out at will or rearranged and combined, so that the arrangement is convenient.
The coil of the loose-leaf coil body is generally made of metal, an opening is formed in the inner leaf for dismounting, and the inner leaf is opened by pulling the inner leaf when the inner leaf is dismounted due to the fact that the opening of the elastic deformation capacity of the metal per se is in a closed state, so that the inner leaf is separated from the opening. However, the inner leaf is too hard to pull or is often torn when the inner leaf is thin, so that the inner leaf cannot be taken out well, and therefore, the pulling force for pulling the inner leaf needs to be increased a little bit when the inner leaf is detached, and the inner leaf is carefully tried out until the inner leaf is taken out well, which is troublesome and inconvenient to use.
