When the impeller pump is used, the outer rotating sleeve 4 rotates, and the inner rotating sleeve 5 is driven to rotate through the isolating sleeve 3 by magnetic coupling, so that the coaxial middle tube 6 and the impeller shaft 7 synchronously rotate, and the impeller pump body 1 is driven to operate so as to drive liquid.
Since the fixed ring sleeve 8 is fixedly installed with the impeller pump body 1 through the supporting wall rod 810, when the coaxial middle tube 6 rotates, the fixed ring sleeve 8 is kept fixed, so that the axial extrusion piece 9 rotates relative to the fixed ring sleeve 8, when the axial extrusion piece 9 rotates, the axial movement of the axial extrusion piece 9 can be driven through the extrusion of the extrusion arc protrusion 811, the reset elastic force of the axial extrusion piece 9 is provided through the piston reset spring 607, and thus the axial extrusion piece 9 axially reciprocates, and when the axial extrusion piece 9 axially reciprocates, the piston body 605 is synchronously driven to axially reciprocate.
