Neck and shoulder kneading and clamping massage machine core

The invention relates to the field of massagers, in particular to a neck and shoulder kneading and clamping massage machine core which comprises a shell, a transmission assembly, a neck massage assembly and a shoulder massage assembly, and an eccentric seat in the transmission assembly drives the neck massage assembly and the shoulder massage assembly to work. A kneading and clamping seat in the neck massage assembly comprises a mounting part, a kneading and clamping arm and a spherical rotating part located between the mounting part and the kneading and clamping arm, the spherical rotating part is rotationally arranged on a shell or a component fixed to the shell, and a rotating cavity is formed in the shell or the component fixed to the shell. The inner wall of the rotating cavity abuts against the peripheral face of the spherical rotating part in a limiting fit mode, limiting guide blocks are symmetrically arranged on the two sides of the spherical rotating part, guide grooves matched with the limiting gui
