[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] 1. When installing the existing impeller, it is necessary to use tools to punch holes in advance, and then use bolts to connect the holes and grooves for fastening. The operation process is relatively cumbersome. The utility model uses the fixed block, the slot, the placement cavity, the bidirectional screw, the block and the handle to pull the positioning rod upward to separate the positioning rod from the positioning slot. Then, the handle is turned to drive the bidirectional screw to rotate. The block threaded on the outer surface of the bidirectional screw moves synchronously and connects with the slot at the fixed block, thereby achieving the purpose of facilitating the docking and installation of the impeller shaft and the body. The structure is simple and easy to operate.

[0014] 2. When the blades of the existing impeller are damaged, it is necessary to disassemble the entire impeller and replace it, and the maintenance cost is high. The utility model provides a mounting plate, a support groove, a support spring, a through groove, a cavity, a rotating rod and a torsion spring. The rotating rod is rotated to make the direction of the rotating rod consistent with the through groove, and then the mounting plate is pulled upward to separate the guide block at the bottom of the mounting plate from the guide groove at the blade. After that, the blade is separated from the fixed plate, thereby achieving the purpose of facilitating the rapid replacement of the blade and solving the problem of overall replacement.
