In the embodiment, the part of the hard shaft 3 away from the soft shaft installation cavity 31 is also provided with an impact part 33, and one end of the hard shaft 3 away from the soft shaft installation cavity 31 is provided with an eccentric notch 34.

[0029] As shown in Figure 1As shown in the drawings, the two ends of the soft shaft 4 are fixedly connected with a first connecting section 41 and a second connecting section 42 respectively, and the first connecting section 41 extends to the outside of the soft shaft mounting cavity 31. The first connecting section 41 and the second connecting section 42 can facilitate the installation and fixation of the soft shaft, and reduce the abrasion caused by the direct installation and impact of the soft shaft.
