Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6 The utility model provides a technical solution: a double-linkage massage movement, comprising: a lower housing 1 and an upper housing 12, the lower housing 1 and the upper housing 12 can be detachably assembled, two limit shafts 121 are symmetrically arranged on the upper surface of the upper housing 12, and the upper housing 12 is detachably provided with a support cover 11 covering the limit shafts 121;

[0025] A symmetrical shoulder massage head 2 and a neck scraping and pressing massage head 3 are arranged above the upper housing 12, and a driving structure 4 and an eccentric transmission structure 5 are arranged inside the lower housing 1 and the upper housing 12. The driving structure 4 drives the shoulder massage head 2 and the neck scraping and pressing massage head 3 through the eccentric transmission structure 5;

[0026] The driving structure 4 includes a bidirectional output servo motor, a double transmission gear 42 and a driven gear 43. The output shaft of the bidirectional output servo motor is an output worm 41. The output worm 41 is meshed with the worm wheel part of the double transmission gear 42. The gear part of the double transmission gear 42 is meshed with the driven gear 43 to realize the transmission of power from the output to the driven gear 43.
