The invention discloses a paper shredder. The paper shredder comprises a lower shell and an upper shell, wherein a first flat plate which is obliquely arranged downwards is arranged on the upper surface of the lower shell, a first through hole is formed in the middle of the first flat plate in the width direction of the first flat plate, and a paper feeding wheel is arranged below the first through hole; the lower surface of the upper shell is composed of a third flat plate, a fourth flat plate, a fifth flat plate and a sixth flat plate, the third flat plate is parallel to the first flat plate, the fourth flat plate is vertically connected to the lower end of the third flat plate, the fifth flat plate is parallel to the first flat plate and is connected to the lower end of the fourth flatplate, and the sixth flat plate is horizontally connected to the lower end of the fifth flat plate; and an arc-shaped groove in the width direction of the sixth flat plate is formed in the portion, located behind the tail end of the second flat plate, of the sixth flat plate, a plurality of first blades perpendicular to the axis of the arc-shaped groove are arranged in the arc-shaped groove, and apushing roller is arranged below the arc-shaped groove. The paper shredder has the advantages that manual paper feeding is not needed, and paper scraps are prevented from being clamped; and meanwhile, the files to be destroyed can be crushed into irregular paper scraps.
Description
technical field [0001] The invention relates to the field of office supplies. More specifically, the present invention relates to a paper shredder. Background technique [0002] A shredder consists of a set of rotating blades, a comb and a drive motor. The paper is fed from the interlocking blades and is divided into many small pieces of paper to achieve the purpose of confidentiality. However, when the traditional paper shredder is working, it needs to manually feed the paper, which requires a lot of manpower. Carry out cutting and crushing, so that it is easy to get some paper scraps stuck between the blades. In addition, traditional paper shredders include horizontal cutting and vertical cutting, so that most of the crushed paper scraps are relatively regular small squares, which are easy to be pieced together Restoration and loss of confidentiality. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned pro...
