Technical Field

[0001] The utility model relates to the technical field of paper processing, in particular to a paper quick positioning device for a paper cutter. Background Art

[0002] Paper cutters are traditional products used to handle paper cutting needs in the later stages of printing.

[0003] After searching, Chinese patent announcement number CN221160590U discloses a paper positioning device for a paper cutter. The utility model can fix the paper on the placement plate through the setting of a limiting mechanism. During use, by starting the micro motor, the gear drives the rack and the slide rail to slide downward through rotation, so that the limit block and the protective pad press the paper, which is convenient for ensuring that the paper will not be shifted during cutting, and can avoid the situation where the worker's fingers are cut by manually pressing the paper with his hands, thereby improving the safety of the device.
