Figure 3 As shown, the cutter installation mechanism 3 includes: an annular cutter seat 31 and a locking semicircular ring 32. The annular cutter seat 31 is sleeved on the cutter shaft 1, and the locking semicircular ring 32 is connected to the annular cutter seat 31 to fix the annular cutter seat 31 on the cutter shaft 1.

[0034] In this embodiment, a mounting hole 321 is provided on the locking semicircular ring 32, and the annular knife seat 31 is fixed to the knife shaft 1 by bolts at the mounting hole 321. Specifically, after the bolts pass through the mounting hole 321 to connect the locking semicircular ring 32 and the annular knife seat 31 together, the annular knife seat 31 is fixed to the knife shaft 1.
