The basic study period is four years, leading to a Bachelor of Management or Bachelor of Engineering degree. Invoice verification is an important financial task, aiming to ensure the authenticity and legality of invoices and prevent fraud. The concept of invoices has broad and narrow interpretations. Broadly speaking, invoices include various securities and certificates, such as stocks, corporate bonds, invoices, and bills of lading. Narrowly speaking, in my country's "Negotiable Instruments Law," invoices mainly include bills of exchange, bank drafts, and checks. These instruments are issued by the drawer, agreeing to unconditionally pay a certain amount of money to the payee or holder upon presentation or on a specified date. In highway engineering, invoice folders are needed when verifying construction cost invoices.

[0003] However, current invoice folders on the market are inconvenient for individually retrieving and verifying invoices during use. This affects the subsequent handling of invoices and hinders the verification process, making it difficult for personnel to perform the verification. Therefore, this utility model provides a portable invoice folder for highway engineering cost invoice verification to solve the aforementioned problems. Utility Model Content

[0032] The working principle of this utility model is as follows: When using this utility model, if it is necessary to store and place the tickets, the semicircular ring 300 and the retaining ring 301 can be separated first. Then, the tickets that need to be stored and checked can be placed inside the storage box 1, and the limiting hole of the ticket can be inserted into the semicircular ring 300 and the retaining ring 301. Then, the retaining ring 301 and the semicircular ring 300 can be brought together. When it is necessary to check the tickets, the tickets only need to be flipped over. At the same time, when it is necessary to check and take out the corresponding tickets, the semicircular ring 300 and the retaining ring 301 can be separated to check and take out the corresponding tickets, which facilitates the individual removal and checking of tickets.

[0033] When it is necessary to carry and protect the documents, after the document verification is completed, the documents can be placed flat inside the storage box 1, and then the cover 2 can be closed. The L-shaped plate 502 can be inserted into the surface of the limiting rod 503 to lock the surface of the cover 2, thus preventing the documents from becoming messy. At the same time, the document folder can be locked and suspended through the locking plate 401, which facilitates the carrying and use of the documents by the staff during subsequent verification and carrying.

[0034] When it is necessary to punch holes in a document without holes, place the document in the position corresponding to the semicircular ring 300 and the retaining ring 301, and then rotate the retaining ring 301. The stamping ring 309 on the retaining ring 301, together with the cutting ring 308, punches holes in the document.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
