摘要： An auxiliary unit of paper shredder cutting tools is installed on cutting tools of a paper shredder. The auxiliary unit is formed by two L-shape plates located between two neighboring blades, an arc-shape hole at an end of each L-shape plate is hooked on a cutting bar of the cutting tool, and a through-hole of each L-shape plate provides for a support rod to be transfixed, so as to stably fix paper guides, the cutting bars and the blades. Therefore, the paper guides, the cutting bars and the blades can be prevented from getting loose or stretched open to damage the paper shredder or result in noise or even an imperfect shredding effect.
摘要翻译：碎纸机的切割工具上安装有切碎机辅助单元。辅助单元由位于两个相邻叶片之间的两个L形板形成，每个L形板的端部处的弧形孔钩在切割工具的切割杆上，并且每个L的通孔固定板提供支撑杆以固定，以便稳定地固定纸张导板，切割杆和刀片。因此，可以防止纸引导件，切割杆和刀片松动或拉伸打开以损坏打碎机，或者产生噪音甚至不完美的切碎效果。

摘要： A paper shredder cutting tool having multiple cutting edges (-) constructed from a pair of cylindrical rotary cutters, which are each separately mounted on a polygonal shaft, and a plurality of cutting blades are securely mounted on the shafts. A paper guide is configured between each pair of adjacent cutting blades, thus partitioning the cutting blades therebetween, and thereby allowing the cutting blades to be assembled and mounted in an interleaving fashion on the two cylindrical rotary cutters. Moreover, each of the cutting blades is further constructed from a pair of blades. Having a plurality of cutting edges circumferentially arranged and minimally separated on each of the pair of blades, thereby forming a compact assembly of blade edges. The paper shredder cutting tool provides capability to feed around tens sheets of paper or cardboard at one time, thereupon being rapidly shredded into small bits. The present invention is characterized that, saw-toothed cutting blades comprising two sets of blades are constructed into a radiate fashion by configuring one set thereof counter clockwise on one half of a shaft, and the other set clockwise on the second half of the shaft. The radiate pattern of the cutting blades prevents the pieces of paper from slanting and enables the paper to be ripped into small bits completely.
摘要翻译：一种具有由一对圆柱形旋转切割器构成的多个切割刃（ - ）的切纸刀切割工具，它们分别安装在多边形轴上，并且多个切割刀片牢固地安装在轴上。在每对相邻的切割刀片之间配置纸张引导件，从而将切割刀片分隔开，从而允许切割刀片以交错方式组装并安装在两个圆柱形旋转刀具上。此外，每个切割刀片还由一对刀片构成。在所述一对叶片的每一个上具有周向布置和最小间隔的多个切割刃，从而形成叶片边缘的紧凑组件。碎纸机切割工具一次可以提供几十张纸或纸板的供应能力，随后快速切碎成小颗粒。本发明的特征在于，包括两组叶片的锯齿切割刀片通过在轴的一半上逆时针地配置一组而另一组在轴的第二半部顺时针地构造成辐射方式。切割刀片的辐射图案防止纸张倾斜，并使纸张完全被撕成小的位置。
