The third pair of massage heads are spherical. The widths of the first pair of massage heads 1, the third pair of massage heads 3 and the second pair of massage heads 2 increase in sequence. The middle second pair of massage heads 2 are convex relative to the other two pairs of massage heads, and the lower third pair of massage heads 3 are convex relative to the other two pairs of massage heads. The first pair of massage heads 1 at the upper part is recessed. Specifically, the first pair of massage heads 1 are tilted relative to each other to facilitate pinching the neck when swinging. The third pair of massage heads 3 are tilted backward in the longitudinal direction to facilitate adapting to the back. The three pairs of massage heads are driven by the same motor 4. An eccentric assembly is provided between each mounting plate and the motor 4. The motor 4 drives the three massage heads to swing synchronously through the eccentric assembly. The eccentric assembly comprises an eccentric wheel 51, a protrusion 52 and a slide groove 53. The mounting plate is an inclined ring arranged on the eccentric wheel 51, and the slide groove 53 is arranged on the movement seat 7 along the front-to-back direction. The protrusion 52 is arranged on the mounting plate, or the protrusion 52 can be arranged on the movement seat and the slide groove 53 is arranged on the mounting plate. The protrusion 52 penetrates into the slide groove 53 to limit the corresponding mounting plate from rotating with the eccentric wheel. Specifically, the eccentric wheel 51 includes a front wheel 511 and a rear wheel 512. The rear wheel 512 has an inclined column 5121. A mounting plate is positioned outside the inclined column 5121 and abuts against the inclined surfaces a on the front and rear wheels 511 and 512. A drive shaft 8 is also provided through the eccentric wheel 51. A limiting shaft 9 is radially provided through the drive shaft 8. Both ends of the limiting shaft 9 abut against a limiting surface 5122 on the back of the rear wheel 512, thereby driving the eccentric wheel 51 to rotate. Alternatively, the limiting shaft 9 is inserted into a limiting groove on the back of the rear wheel 512. The front wheel 511 and the rear wheel 512 are connected by an insert 5a and a slot 5b, and are locked by screws. The insert 5a is integrally provided on the back of the front wheel 511 or the front end of the rear wheel 512.

[0028] Specifically, a guide frame 54 with a slide groove 53 is provided on the movement base 7 and below the corresponding pair of mounting plates A61. The lower ends of the pair of mounting plates A61 are provided with a protrusion 52, which is inserted into the slide groove 53 of the lower guide frame 54. The first pair of massage heads 1 swings up and down.

[0029] A guide frame 54 is provided on the movement base 7 and between a pair of mounting plates B62. Slide grooves 53 are provided on the left and right sides of the guide frame 54. Protrusions 52 are provided on the opposite sides of the pair of mounting plates B62. The pair of protrusions 53 are respectively installed in the slide grooves 53 on both sides of the middle guide frame 54.
