[0019] like Figure 2 As shown, the adapter assembly 2 has a connecting portion 5 on the top and a mounting portion 6 on the bottom. The connecting portion 5 is provided with at least one of a clamping joint or a clamping groove, a positioning head or a positioning groove 7. A groove is provided in the middle of the mounting portion 6 below for inserting the treatment head assembly 4. A fixing plate 8 is installed below the mounting portion 6 for connecting one end of the adapter assembly 2. The other end of the rotating assembly 2 is connected to the treatment head assembly 4.

[0020] like Figure 3 As shown, the connecting portion 5 is provided with at least one locating pin 9, a card plate 10, and a male end 11 of the connector.

The male end 11 of the connector corresponds to the female end of the connector on the physiotherapy device body, and is connected and fixed to the physiotherapy device body through the locating pin 9, the male end 11 of the connector, and the card plate 10.

[0021] The treatment head assembly 4 is a truncated cone-shaped structure that is wide at the top and narrow at the bottom. A protruding connecting head 12 is provided in the middle position of the top. The connecting head 12 is inserted into the groove provided at the bottom of the adapter assembly 2, leaving a certain gap between the connecting head 12 and the top of the groove.
