[0002] Paper cutters are traditional products used to handle paper cutting needs in the later stages of printing. They have evolved from mechanical paper cutters to tape-controlled paper cutters, and then to microcomputer-controlled, color-display, full-image operation-guided visual processing, and computer-aided cutting systems with external programming and editing of production data.

[0003] The existing patent application number is 202123368269.X, which discloses a protective device for a paper cutter, including a paper cutter box, a cutting table is fixedly installed inside the paper cutter box, a control panel is fixedly installed on one side of the paper cutter box, and a cleaning mechanism is fixedly installed on the top of the cutting table; the protective mechanism includes an empty slot, an empty slot is opened inside the cutting table, and a No. 1 limiting slide is opened on the top of the cutting table, and a connecting rod is slidably installed inside the No. 1 limiting slide. The utility model is provided with a protective mechanism to control the distance between the No. 2 push plate and the blade, so that one side of the paper is positioned by the No. 2 push plate and then cut, and the No. 2 push plate pushes out the cut paper. The whole process is completed by the No. 1 push plate and the No. 2 push plate. The staff is away from the blade and does not need to push the paper in manually, which increases the safety of the equipment. Although the device adds a protective device, the structure is too complicated. When the paper cutter fails, it takes a lot of time to remove the external parts, resulting in low practicality of the device. Utility Model Content
