Thus, the interfitting of the telescoping rod 410 and jack 3021 ensures that the output shaft assembly 30 can be reengaged with the coupling assembly 40 after disconnection. At least a part of the body of shaft coupling subassembly 40 is equipped with one or more than two connecting holes, for example, can be equipped with first connecting hole 4012 and second connecting hole 4013 radially symmetrically, and first connecting hole 4012 and second connecting hole 4013 all set up axially, that is, the central line of first connecting hole 4012, the axle center of second connecting hole 4013 central line and the body of shaft coupling subassembly 40 are parallel to each other.

Specifically, the rod body 403 includes a large diameter portion and a small diameter portion, wherein the large diameter portion has a hole therein, and the first elastic member 404 extends into the hole to connect with the large diameter portion. The smaller diameter portion may extend into the receptacle 3021 and may be used to connect the output shaft assembly 30. The step is formed between the large-diameter part and the small-diameter part, the output shaft assembly 30 can be limited, and noise caused by mutual collision of the output shaft assembly 30 and the coupling assembly 40 is avoided. When the telescopic rod 410 cannot be inserted in alignment with the jack 3021, the telescopic rod 410 has an axial telescopic function, so that the end of the telescopic rod 410 is retracted into the body of the coupling assembly 40, and once the telescopic rod 410 is rotated to a position aligned with the jack 3021, the telescopic rod 410 is ejected and then connected to the output shaft assembly 30. Thus, the telescoping rod 410 ensures the connection between the coupling assembly 40 and the output shaft assembly 30. When the coupling assembly 40 and the output shaft assembly 30 need to be disconnected, only the output shaft assembly 30 is separated, and the jack 3021 is separated from the rod body 403 of the telescopic rod 410, so that the structure is simple and easy to implement.
