A massaging machine core capable of achieving swinging massaging comprises a shell, a driving device, a first massaging assembly and a second massaging assembly. The massaging machine core is characterized in that the driving device comprises a motor, a first kneading gear assembly and a second kneading gear assembly, wherein the first kneading gear assembly comprises a first rotation wheel and a first eccentric shaft fixedly installed on the first rotation wheel, and the first massaging assembly is connected with the first eccentric shaft in a swinging mode and the second kneading gear assembly comprises a second rotation wheel and a second eccentric shaft which can be installed on the second rotation wheel in a sliding mode in the circumferential direction, and the second massaging assembly is connected with the second eccentric shaft in a swinging mode. According to the massaging machine core, the eccentric shaft of one kneading gear assembly is of a sliding structure, massaging arms of the two massaging assemblies can achieve two motion modes which are swinging in the same direction and swinging with a certain angle, and massaging forms are diversified through the design that the front massaging arm and the rear massaging arm of each massaging assembly form a certain angel, massaging heads are closer to the neck and shoulders, force is even, and more comfortable and ideal massaging effects are achieved.
