The sliding shaft 7 is connected with the lifting plate 4. The third spring 5 is arranged in the sleeve 6. The two ends of the third spring 5 are respectively connected with the sliding shaft 7 and the guide rail 21.

[0033] In the embodiment, as shown in Figure 2 The guide rail 21 is in a U-shaped structure and the two sides of the guide rail 21 are U-shaped plates. The number of the blocking pieces 22 is two. The two blocking pieces 22 are respectively located at the two sides of the guide rail 21. The cutting piece 3 comprises a base and a cutter. The cutter is connected with the base. The base is slidably connected with the guide rail 21. The base is provided with a groove. The cutter of the lower cutting piece 3 is sleeved in the groove of the base of the upper cutting piece 3. The space of the cutting piece 3 on the guide rail 21 is saved, so that more cutting pieces 3 can be arranged on the guide rail 21.

[0034] On the guide rail 21, a plurality of cutting pieces 3 are arranged in order from top to bottom, the lifting plate 4 slides between the guide rails 21 and the lifting plate always abuts against the lowermost cutting piece 3, the plurality of cutting pieces 3 are clamped by the lifting plate 4, the blocking piece 22 and the guide rail 21, it should be pointed out that in order to avoid that the cutting piece 3 cannot process the corrugated board, the third spring 5 needs to have strong elasticity;

[0035] When the cutter of the first cutting piece 3 is worn, the worker needs to pause the machine, slide the blocking piece 22, so that the first cutting piece 3 can be directly taken out from between the guide rails 21, then the second cutting piece 3 is lifted, at this time the third spring 5 lifts the lifting plate 4, the second cutting piece 3 is lifted to the position before the first cutting piece 3 is taken out, then the blocking piece 22 is moved to limit the position of the second cutting piece 3, so as to realize the replacement of the cutter without the need to reinstall the cutter.
