[0022] In this embodiment, the knife rod 6 is movably connected to the bottom end of the rotating rod 4 through the universal joint 5 and is arranged to rotate synchronously. The positioning cylinder 8 is sleeved on the outer periphery of the rotating rod 4 and is arranged to be movable up and down. The angle of the knife rod 6 is adjusted through the universal joint 5, and the rotation is transmitted through the universal joint 5.

[0023] In this embodiment, a thread is provided through the inner wall of the positioning sleeve 7, and the first thread section 9 is located on the inner wall of the positioning sleeve 7 and is threadedly connected. The positioning tube 8 slides upward to connect and fix the first thread section 9 to the inner wall of the positioning sleeve 7 to adjust the bending angle of the tool rod 6.
