A swing fatigue test device for a double-section metal corrugated pipe comprises a sliding groove fixing platform, a test piece limiting mechanism and a power swing mechanism, and is technically characterized in that one end of a corrugated pipe test piece in the test piece limiting mechanism is limited and fixed to a square limiting frame, and the other end of the corrugated pipe test piece is axially limited to the square limiting frame; a flange swing rod of a swing end flange on the corrugated pipe test piece is rigidly connected with the swing rod through a support rod; while the motor drives the swing rod to swing, the other end of the corrugated pipe test piece swings and slides on the cambered surface slideway of the square limiting frame; the swing end flange is driven by the power swing mechanism to swing back and forth, so that the swing fatigue life test of the corrugated pipe test piece is realized. Wherein the swing angle control can be realized by adjusting the stroke of the motor; for corrugat
