In the above patent, although it is convenient to flatten the paper, in practical application we find that there still exist certain disadvantages, such as:

1. the paper flattening device does not have the function of flattening paper, and the paper is easy to tear and damage if the paper is singly flattened;

2. the paper flattening device is inconvenient for fixing multiple layers of paper, and the paper is easy to move around in the process of flattening the paper, so that the paper flattening effect is influenced;

3. above-mentioned paper flattening ware is relatively poor to the effect of leveling of paper, and the concrete expression does: in the reset process of the pressing and pulling roller, the pressing and pulling roller can push paper reversely, so that the previous leveling failure is caused, and even inward wrinkles can be generated on the paper;

based on this, we propose an adjustable paper flattening ware for financial accounting, hope solve the weak point in the prior art.
