[0002] A tender document storage device is a device or system dedicated to storing and managing business documents such as tender documents and bidding documents, and mainly serves tendering units or procurement departments. It can help to orderly store, classify and retrieve numerous tender documents received, thereby improving work efficiency and ensuring the smooth progress of business processes. This device is designed to simplify the document management process and ensure the neat storage and safe custody of documents. Its easy classification feature helps to quickly locate documents, reduce errors and omissions, facilitate audits, and keep the workplace clean and orderly. Existing tender document storage devices usually implement classification operations by fixedly setting different physical compartments or drawers, each compartment or drawer is marked with different classification identifiers, such as project name, tender unit or date. This structure organizes files through determined physical separation, which is convenient for users to quickly access and retrieve files according to classification identifiers. However, this fixed physical classification structure may have disadvantages such as low space utilization, poor classification flexibility, insufficient scalability, and easy accumulation and confusion of files.

[0003] After searching, the existing patent (publication number: CN219396665U) discloses a "This application involves the field of storage tools, and discloses a bidding document storage device, including a file rack, a plurality of placement plates are fixedly installed inside the file rack, and a movable partition is movably installed on the upper surface of the placement plate. A fixed groove is opened in the middle of the front end of the movable partition, and a protective baffle is rotatably installed at one end of the inner wall of the fixed groove. An inner groove is symmetrically opened on one side of the protective baffle. A movable rod is movably installed inside the inner groove, and an L-shaped card is fixedly connected to one end of the movable rod. A limiting mechanism is also provided inside the movable partition; this application uses a plurality of movable partitions to block between two adjacent bidding documents, thereby achieving the effect of classifying and placing the bidding documents stored in the file rack, avoiding the problem of chaotic placement of different types of bids piled up inside the file rack, and improving the neatness of the bidding documents when they are stored."
