Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Figure 1 shows a knife bar assembly, which is used to install in a paper shredder for paper shredding operation. It includes a frame body 1 and two parallel knife shafts, and the two ends of each knife shaft are respectively passed through the frame. Body 1, a number of blades for paper shredding are set in series on the shaft body of each cutter shaft, the blades on the two cutter shafts are interlaced with each other, the top surface of the frame body 1 is provided with a paper feeding channel 11, and the bottom surface of the frame body 1 is provided with an outlet In the paper channel, a transmission gear is provided at one outer end of one of the cutter shafts, and a transmission interface connected with the transmission gear is provided at one outer end of the other cutter shaft. When the knife bar assembly is placed in the cutter accommodation chamber 3 of the paper shredder, the transmission interface on one side of the knife bar assembly is connected to the transmission mechanism of the knife accommodation chamber 3 .

Specifically, the transmission interface includes a first transmission chuck 2 , the transmission mechanism includes a second transmission chuck 4 , and the second transmission chuck 4 is connected to the first transmission chuck 2 after the knife bar assembly is placed in the tool accommodation cavity 3 . The inner edge of the first transmission chuck 2 is provided with a gear part meshed with the transmission gear, the outer edge of the first transmission chuck 2 is provided with some protruding passive transmission parts 21, and the second transmission chuck 4 is provided with several The active transmission part, after the knife bar assembly is placed in the tool accommodating cavity 3, the active transmission part of the second transmission chuck 4 pushes the passive transmission part 21 of the first transmission chuck 2, and the second transmission chuck 4 drives the first transmission Chuck 2 rotates.

To sum up, the knife bar assembly of the present invention is provided with a transmission interface matched with the transmission mechanism of the paper shredder, and can be made into a modular replaceable or replaceable assembly, which is an independent assembly or accessory.

The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. limits.
