The contact element 302 is a pyramidal structure. The hydraulic telescopic rod 301 is used to drive the contact element 302 to move up and down through telescopic movement. As the contact element 302 moves up and down, it contacts the mounting rod 401, thereby driving the fixing component 404 to clamp the impeller. The fixing mechanism 4 includes: a mounting rod 401, which is slidably disposed inside a circular hole on the mounting member 201; a mounting plate 403 is disposed on the mounting rod 401; and a fixing member 404 is disposed on the mounting plate 403.
