Technical Field
[0001] The utility model belongs to the technical field of paper cutters, and particularly relates to a paper cutter with a function of wrinkling paper strips. Background Art
[0002] Traditional paper cutters mostly focus on cutting accuracy and operation convenience, while ignoring other needs of users in actual operation. However, with the increasing diversification of user needs, the market has put forward higher requirements for the functionality and user experience of paper cutters. For example, when the paper handling capacity of the paper cutter is large, the receiving paper box barrel needs to be cleaned. The structure of the traditional paper cutter is relatively fixed and requires the use of a screwdriver for disassembly, which is not convenient for quick disassembly and assembly, making the cleaning, maintenance or replacement of parts a complex and time-consuming process. In addition, after disassembly, users often directly place the paper cutting cover on the ground or the tabletop, and the bottom of the machine directly contacts the ground without a buffer pad or other protection devices. The paper cutting core in the paper cutting cover is easily damaged due to accidental collisions, increasing the maintenance cost.
[0003] Therefore, based on some of the above situations in the prior art, the present application has been further designed and improved. Summary of the Utility Model
[0004] In order to solve the above technical problems, the utility model is solved by the following technical solutions.
