Through the technical scheme, when the compressor operates, the driving source drives the eccentric shaft 4 to rotate and then drives the movable vortex disk 2 to move, the movable vortex wall 21 and the fixed vortex wall 31 relatively operate, the refrigerant entering from the inlet 11 enters the outermost side to form the sealed compression cavity 5, the compression cavity 5 continuously moves inwards along with the movement of the movable vortex disk 2, the compression cavity 5 continuously reduces in the inward movement process to compress the refrigerant until the refrigerant moves to the central position, the refrigerant leaves from the through hole 32 and is then output from the output port 12, and the suction, compression and exhaust processes are simultaneously and continuously performed. When the compressor is overloaded (the pressure of the refrigerant in a certain compression cavity 5 between the movable vortex wall 21 and the fixed vortex wall 31 is too high), the too high pressure acts on the movable vortex disc 2, so that the movable vortex disc 2 is separated from the fixed vortex disc 3, the pressure of the refrigerant in each compression cavity 5 is balanced, and then the movable vortex disc 2 is reset. When the overload causes the movable scroll 2 to move, the movable scroll 2 moves towards the buffer ring 61, so that the springs 62 are compressed, and after the pressure of the refrigerant in each compression cavity 5 is balanced, the springs 62 are reset to drive the movable scroll 2 to reset.
