The first drive shaft 50 is provided with only one first positioning portion 51, and the second drive shaft 60 is provided with only one second positioning portion 61. The first positioning portion 51 and the second positioning portion 61 are circumferentially aligned so that the structure of the first positioning portion 51 and the second positioning portion 61 can be fit with the fitting portion in a rotation-stop manner, and there is no relative movement between the first drive shaft 50 and the second drive shaft 60.

When the first drive shaft 50 is engaged with the second drive shaft 60, there is only one connection position between the first drive shaft 50 and the second drive shaft 60, that is, there is a first preset position of the first drive shaft 50 relative to the second drive shaft 60 and a second preset position of the second drive shaft 60 relative to the first drive shaft 50, and the first preset position corresponds to the second preset position. The first drive shaft 50 or the second drive shaft 60 is rotated when the first drive shaft 50 is not in the first preset position relative to the second drive shaft 60, or the first drive shaft 50 or the second drive shaft 60 is rotated when the second drive shaft 60 is not in the second preset position relative to the first drive shaft 50. The first and second positioning structures may be holes, grooves, or planes, which are not specifically limited in this application.

Compared with the concave-convex positioning structure or other positioning structures in the prior art, the concave-convex positioning structure has two connecting positions, for example, in the first connecting position, the first driving shaft 50 and the second driving shaft 60 can be connected, and in the second connecting position, the first driving shaft 50 rotates 180 degrees relative to the second driving shaft 60, and the first driving shaft 50 and the second driving shaft 60 can be connected again.
