[0030] Two engaging grooves 10 are provided on both sides of the limiting plate 4 in a centrally symmetrical manner. Mounting grooves 11 are provided on both sides of the engaging grooves 10. A sharpening strip 12 is embedded and connected to the inner sides of the two engaging grooves 10. The depth of the engaging groove 10 is greater than the depth of the mounting groove 11. The disassembly seat 13 and the mounting groove 11 are detachably connected by disassembly screws. The distance between the sharpening strip 12 and the trimming knife 9 is smaller than the distance between the limiting plate 4 and the trimming knife 9. When the trimming knife 9 rotates, its edge can be released from the sharpening strip 12, thereby achieving sharpening, and both ends of the sharpening strip 12 are fixedly mounted in the mounting groove 11 through the disassembly seat 13.

[0031] A limiting knife groove 14 is provided inside the connecting turntable 8 corresponding to the pruning knife 9, and a knife seat 15 is connected to the end of the pruning knife 9. The knife seat 15 is embedded in the limiting knife groove 14, and the knife seat 15 and the connecting turntable 8 are detachably connected by a fastening bolt 16.
