[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. By using the cooperation of the fixing posts and the caps, a plurality of blades are respectively sleeved outside a plurality of fixing posts, and then locked by the caps, so that each blade is installed separately. When the blade on the impeller is damaged, the damaged blade can be disassembled and replaced separately, without the need to replace the entire impeller, saving costs and reducing economic losses.

[0015] 2. Through the arrangement of the limiting assembly, the limiting assembly is used to limit the blades, so that the blades can be further fixed, thereby preventing the angles of the blades from changing and improving the stability of the blade installation.

[0016] 3. Through the arrangement of the second socket and the third socket, the carriage is inserted into the second socket or the third socket, so that the angle of the blade can be changed, realizing the adjustment of the blade angle and improving the use effect of the impeller.
