Description

Technical Field

[0001] The utility model relates to the technical field of bill binding, in particular to a bill binding device. Background Art

[0002] Accounting receipts are written evidence compiled in a certain format to record economic transactions, clarify economic responsibilities, and are used to register accounting books. For company accountants and other financial personnel, they have to deal with a large number of receipts and bills every day. Regularly and quantitatively organizing various receipts and binding them into books plays an important role in the verification of accounts and subsequent audit and clearance work. Therefore, binding a certain number of receipts into books of standard thickness has become a part of the daily work of accountants and other financial personnel.

[0003] When using traditional means to punch and bind bills, there are certain requirements for the individual's physical fitness. It is difficult to punch through very thick bills if the physical strength is insufficient, and the efficiency is low. Therefore, some bill binding devices that can automatically punch bills have appeared on the market.

[0004] However, existing bill binding devices can either only punch one hole in a bill at a time, which is inefficient; or can punch multiple binding holes at the same time, but the spacing between the binding holes cannot be adjusted, making it difficult to adapt to bills of different sizes. In addition, most bill binding devices cannot assist in fixing the bill binding device during binding, making it easy for the bill binding device to slide or move during binding, and the sliding or moving during binding can easily affect the binding effect. Therefore, the existing needs are not met. In this regard, we propose a bill binding device. Utility Model Content
