Equipped with the second connector 43, the proximal end of the second connector 43 is fixed in ontology 1, and the close end of adapter 41 is hinged by second
The distal end articulated of portion B and the second connector 43.In another alternate embodiment, switching is fixed in the distal end of the second connector 43
In part 41, the second adapter 42 it is hinged proximally by the second articulated section B and ontology 1.
The second slot 410 passed through for impeller 3 is equipped in adapter 41；The portion of impeller 3 being located in adapter 41
Divide and is swung with the swing of adapter 41.
Such as the first above-mentioned slot 21, in an alternate embodiment of the present invention, the second slot 410 also be can have
The shape of similar first slot 21, specific: the aperture of the second slot 410 is proximally to being distally gradually reduced, so that pushing
Part 3 can be swung in the longitudinal direction relative to adapter 41.
In the present embodiment, as shown in Fig. 1,4 and 5, the guide sleeve 44 of impeller 3 is additionally provided in adapter 41；Guide sleeve
The third slot 440 passed through for impeller 3 is equipped in 44；Impeller 3 extends the proximal end for penetrating third slot 440, warp from ontology 1
By third slot 440, it is pierced by from the distal end of the second slot 410.
In the present embodiment, as shown in Fig. 1,4 and 5, the aperture of the second slot 410 proximally to be distally gradually reduced to
So that guide sleeve 44 can be swung in the longitudinal direction in the second slot 410 relative to adapter 41.It, can be more preferable using the structure
Ground mitigates the case where bending catastrophe phenomena for being located at the impeller 3 of 1 junction of adapter 41 and ontology, avoids impeller 3 in adapter
It is obstructed at 41, reduces resistance when percussion.
In the present embodiment, referring to figs. 5 and 6, third slot 440 has the proximal part 441 positioned at its proximal end；This is close
The aperture of end part 441 from proximally to be distally gradually reduced so that impeller 3 third slot 440 proximal part
It can be swung in the longitudinal direction relative to guide sleeve 44 in 441.Using the structure, can preferably mitigate positioned at adapter 41 and this
The case where bending catastrophe phenomena of the impeller 3 of 1 junction of body, impeller 3 is avoided to be obstructed at adapter 41, reduces resistance when percussion
Power.
Specifically, foring the installation slot position 411 of installation guide sleeve 44 inside the second slot 410, guide sleeve 44 can be
Relative to 41 longitudinal oscillation of adapter, (paper shown in as shown in Figure 1, Figure 3 and Figure 4 is that one of guide sleeve 44 indulges in installation slot position 411
To swinging plane).
Installing slot position 411 has the first cell wall 411a and the second cell wall 411b.
