Description

Technical Field

[0001] The utility model relates to the technical field of paper cutting, in particular to a paper cutter with a positioning cutting structure. Background Art

[0002] During the copy paper production process, copy paper needs to be cut to certain specifications. A paper cutter is a device used to cut copy paper. In the prior art, when a paper cutter is in operation, a worker must neatly place the copy paper to be cut on a workbench, then push the copy paper forward. A baffle positions the copy paper front and back to determine the cutting size. The cutter then drops to complete the single-sided cutting of the copy paper. Since copy paper production requires cutting each of the four edges of the paper separately, workers need to manually adjust the position of the paper multiple times, resulting in high labor intensity. Furthermore, after working for a long time, workers are prone to fatigue, which can lead to a decrease in concentration and accidents. Utility Model Content
