Backup plate in the utility model page puncher, it has the indent of square on the end face that reclines with page.This indent be used to recline angle of page makes both sides, paper angle folded neat.

When using the page puncher, rotate hand lever earlier, at this moment cutlery is moved up and down, finish the action of page punching by transmission mechanism.The paper scrap that punching is come out is stayed in the cutlery, and with the increasing and constantly move up of paper scrap, in being discharged to the waste material box.

The utility model has the advantages that: 1) after the end inwall of cutlery cutting edge end is provided with the internal diameter damping section little than the cutlery bore, the conical duct of cutlery is changed into the cylindrical bore of ladder, so handling ease, wall thickness are more even, its intensity, rigidity can improve widely; The less internal diameter of 2) damping section inwall can guarantee paper scrap at thereafter unimpeded than in the macropore after the paper scrap periphery is tightened, therefore, need not consider to be worth doing clearly cutlery, easy to use; 3) on backup plate, be provided with after the indent of square, not only can on page, get the hole line of centres hole parallel with the trimming, also can get its hole line of centres of being positioned on the page angle with uneven hole, trimming, so the utility model page puncher can be used for the bookbinding punching of financial voucher.
