[0002] Office shredders, also known as paper shredders, are office equipment used to break, tear, and shred paper. They are mainly composed of a set of rotating blades, paper combs, and drive motors. The motor drives the blades to rotate and cut the paper into small pieces to achieve confidentiality or convenient handling. There are many types and specifications of paper shredders according to different usage scenarios and needs. For example, desktop shredders are small, light, and easy to carry, suitable for use on desks; deskside shredders are slightly larger, but are also suitable for being placed next to desks, and usually have higher cutting capabilities and capacity.

[0003] Publication number "CN219880135U" is a paper shredding device for office use, which includes: a paper shredder, a shredder core is fixedly connected to the inside of the shredder, sound insulation cotton is arranged inside the shredder, a feed bin is fixedly connected to the upper surface of the shredder, a silent glass cover is hinged to the outer side of the feed bin, a shredder bin is fixedly connected to the lower end of the shredder, a hinge is fixedly connected to the outer side of the shredder bin, a bin door is hinged to the hinge, and a combination lock is fixedly connected to the outer surface of the bin door. Through the above structure, the inside of the shredder is provided with sound insulation cotton, so that the shredder core inside the shredder can make the equipment run more quietly when shredding paper. And the designed feed bin makes it easy to put in multiple sheets of paper, and the silent glass cover makes it easy to observe during the shredding process, and achieves the effect of sound insulation.
