[0001] The utility model relates to the technical field of paper shredder equipment, in particular to a new type of paper shredder with a gear protection structure. Background Art
[0002] At present, shredders are a common office equipment used to shred discarded documents. Common shredders are composed of a set of rotating blades, paper combs and drive motors. Paper is fed from the middle of the interlocking blades and is cut into many small pieces of paper to achieve the purpose of confidentiality. Due to its convenience, it has been more and more widely used in office places. There are at least the following disadvantages in the use of existing new shredders: when overload occurs, its mechanical parts such as gears, shredders and motors cannot be protected. In other words, when excessive paper is put into the shredder that exceeds the rated shredding amount, the machine may be stuck or the teeth may be broken due to the thickness of the paper, which may cause the machine to fail. In serious cases, the motor may fail. Therefore, we have introduced a new shredder with a gear protection structure. Utility Model Content
