[0011] By adopting the above technical solution, the mounting seat can facilitate the installation of the massage hammer, and the mounting seat is limited by the limiting structure, so that the overall stability of the mounting seat is better. Furthermore, the massage hammer is more stable when in use.

[0012] The utility model is further configured as follows: the limiting structure comprises a screw sleeve for locking the mounting seat on the output shaft and a limiting surface arranged on the mounting seat, the screw sleeve is threadedly matched with the output shaft, a plurality of limiting surfaces are arranged, and they abut against the output shaft.

At the same time, the control system sets the basic massage strength according to the strain gauge data. The relationship between the basic massage strength F and the user's weight is F=kmg, and k is a constant that can be set during initialization to facilitate control of the massage strength.
