the fixing mechanism comprises a sleeve movably connected to one end of the shaft, a through groove matched with the shaft is formed in the sleeve, a positioning key is fixedly connected to the top of the inner wall of the sleeve, and the positioning key is matched with the key groove.
Preferably, the both sides at sleeve surface top all threaded connection has the bolt, and the bolt is provided with two, the bottom of bolt runs through the locating key and extends to the inside of axle, the screw hole with bolt looks adaptation has all been seted up to the both sides at axle surface top.
Preferably, a round bar is fixedly connected to one side of the front surface of the sleeve.
Preferably, an impeller is rotatably arranged in the pump body.
Advantageous effects
The utility model provides an anti-rotation member for pump assembly. Compared with the prior art, the method has the following beneficial effects: according to the anti-rotation piece for pump assembly, the positioning key is inserted into the key groove, the sleeve, the positioning key and the shaft are fixed by the bolts, so that the problem that the key groove is damaged by using the dog head spanner is avoided, and the shaft can be easily fixed.
