The patent application publication TW201410230A discloses another massage movement with shoulder-gripping massage function, which also enables the applicator to be moved up and down to close and separate for massaging the user when a massage member performs a kneading action. The upper and lower massage fingers (applicators) of the two massage movements are interlocked, and when massaging the shoulders of the user, the upper and lower massage fingers (applicators) are reciprocally separated and approached.

However, in the use process, a person skilled in the art finds that, due to the limitations of the components and the connection relationship between the components, the shoulder-clamping massage mechanism in the motion conversion device in the above-mentioned application embodiment cannot achieve a satisfactory massage force in the human body massage process or can achieve the satisfactory massage force but the strength of the motion conversion device is not enough, and cannot support the massage force for a long time.
