1. A scroll compressor, comprising:
a scroll mechanism, wherein the scroll mechanism comprises a non-orbiting scroll, the non-orbiting scroll comprises a non-orbiting scroll end plate and a non-orbiting scroll wrap and an outer peripheral wall extending from one side of the non-orbiting scroll end plate, the outer peripheral wall is arranged at a periphery of the non-orbiting scroll wrap; and
a main bearing seat, wherein the main bearing seat is configured for supporting the scroll mechanism and comprises a main body part and an axial seat portion extending axially from the main body part, a circumferential annular groove is formed at an inner peripheral surface of the axial seat portion,
wherein the scroll compressor further comprises an elastic ring arranged between the outer peripheral wall and the axial seat portion and a pushing structure located at a radial inner side of the elastic ring and configured for forcing the elastic ring to expand radially outward, so that a part of the elastic ring in a radial direction is inserted in the circumferential annular groove to limit axial movement of the non-orbiting scroll away from the main bearing seat.
