It is an economic management work that uses currency as the main unit of measurement and applies special methods to calculate and supervise the economic activities of a unit. Accounting professional bills are securities that the issuer unconditionally promises to pay a certain amount of money by himself or others. Accounting professional bills use a punching device to punch installation holes on the bills to facilitate the installation and stacking of multiple accounting professional bills.

[0003] The punching device of the accounting professional invoice punches multiple holes on the invoice. After the invoice is pushed to the punching position, the nail rod is inserted downward into the invoice to punch holes. However, the invoice material is relatively soft. When the nail rod is inserted into the invoice, it is easy to cause the invoice to shift toward the punching slot, causing the invoice to shift when the holes are nailed. At the same time, some invoices are not kept flat due to storage problems. The surface has corners, and they are folded and warped when placed on the punching device, causing the punching position to shift, resulting in deviations in the punching positions of multiple accounting professional invoices.
