[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below.

[0043] In the description of the present invention, it should be understood that terms such as "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0044] As shown in Figures 1 to 8, a preferred embodiment of a shoulder and neck massager of the present invention includes a shell 1, a motor housing, a drive assembly, a push rod 3, a mounting seat 281, a massage head 4 and two shoulder straps 8. The push rod 3 is connected to the drive assembly and the shell 1 and is limited by the shell 1. The push rod 3 partially extends out of the shell 1 and swings up and down; the mounting seat 281 is connected to the drive assembly and is set through the shell 1. The massage head 4 is detachably mounted on the mounting seat 281, and the massage head 4 rotates and swings with the mounting seat 281; the drive assembly is installed in the movement housing, and the drive assembly drives the push rod 3 and the massage head 4 to move.
