Problems solved by technology

Accounting vouchers are the basis of accounting and accounting, and need to be bound for storage. Usually, accounting vouchers need to be bound into books on a monthly basis. The usual method is to use an awl to tap the hole and then stitch it together. The taper hole is labor-intensive and low in efficiency.

Although there are mechanical punching devices on the market, there is a defect in these punching devices, that is, when punching holes, the paper on the upper layer will have a page error compared to the paper on the lower layer. During the process, the force on the upper layer of paper and the lower layer of paper is inconsistent, so the punched holes will be inclined, and the binding will be irregular. The punching machine needs to be placed on a special table, which takes up a lot of space and is inconvenient to use.
