The invention belongs to the technical field of motor rotors, and particularly relates to a rotor structure of a squirrel-cage asynchronous motor. According to the technical scheme, the rotor structure of the squirrel cage asynchronous motor comprises a rotating shaft, a plurality of rotating shaft opening grooves are formed in the rotating shaft in the axial direction, squirrel cage strips are arranged in the rotating shaft opening grooves, the end of the rotating shaft is sleeved with an end ring, a plurality of end ring opening grooves are formed in the end ring in the axial direction, and the ends of the squirrel cage strips are arranged in the end ring opening grooves. The end rings are sleeved with protective rings used for pressing the ends of the mouse cage strips, the ends of the mouse cage strips are provided with a plurality of mouse cage strip holes arranged in the radial direction, and elastic pre-tightening elements are arranged in the mouse cage strip holes. The rotor structure of the squirrel
