Abstract: An adjustable blade of an impeller built-in electric pump includes a blade body, where the blade body realizes an angle adjustment through a lever regulator structure. The lever regulator structure includes a control shaft arranged at a root of the blade body, the other end of the control shaft is connected to a crank, the other end of the crank is rotatably connected to one end of a connecting rod, the other end of the connecting rod is rotatably connected to an operating frame, and the operating frame is provided with a drive rod configured to drive the operating frame to move. The adjustable blade of the impeller built-in electric pump has the advantages of being compact and simple, low manufacturing cost and low difficulty of installation and maintenance. Moreover, by adjusting the angle of the blade, the vibration during the start-up of the unit can be effectively reduced.
