[0026] Specifically, the rotating assembly includes a rotating shaft 5, a rotating positioning plate 6, a fixing plate 7, a spring plate 8, a gasket 9, a fixing screw 10 and a locking screw 11, wherein the rotating shaft 5 passes through the massage chair head cap 1 and the fixing plate 7, and the fixing plate 7 is fixedly mounted on the surface of the rotating seat 13;

[0027] The rotating shaft 5 includes a screw and a female head. The screw part is inserted into the rotating seat 13. The screw part is threadedly connected to the fixing screw 10 and the locking screw 11. The screw part is also sleeved with a spring piece 8 and a gasket 9. The spring piece 8 is radially fixed to the screw part. The spring piece 8 and the gasket 9 are located between the surface of the rotating seat 13 and the fixing piece 7. The spring piece 8 is located between the gasket 9 and the fixing piece 7. The clamping degree between the spring piece 8 and the gasket 9 and the fixing piece 7 is adjusted by the fixing screw 10, thereby adjusting the friction between the spring piece 8 and the fixing piece 7. The locking screw 11 is used to limit and lock the fixing screw 10 to prevent the fixing screw 10 from loosening.

[0028] A limiting shaft 71 is provided on the outer surface of the fixing piece 7, the rotation positioning piece 6 is radially fixedly arranged on the rotation shaft 5, and limiting protrusions 61 are integrally provided on both sides of the rotation positioning piece 6. The limiting shaft 71 is used to limit the limiting protrusions 61, so that the rotation angle of the rotation positioning piece 6 is limited, and further the rotation angle of the rotation shaft 5 is limited;

[0029] The rotation positioning piece 6 and the rotation shaft 5 can be integrally arranged, and can also play a role of synchronous rotation, and can also cooperate with the limiting shaft 71 to achieve the function of limiting the rotation angle;

[0030] A long slot is provided on the female head of the rotating shaft 5, and the inner plate 2 of the head cap is installed on the female head. A socket 21 is provided on the inner side of the inner plate 2 of the head cap, and two inserts 22 are provided in the socket 21. The inserts 22 are slidably inserted into the long slot to achieve radial fixation of the rotating shaft 5 and the inner plate 2 of the head cap, so that the inner plate 2 of the head cap can drive the rotating shaft 5 to rotate;

[0031] The screw of the rotating shaft 5 has two parallel chamfers to form four edges, which cooperate with the flat hole 62 opened by the rotating positioning piece 6 to achieve radial fixation of the rotating shaft 5 and the rotating positioning piece 6, so that the rotating shaft 5 and the rotating positioning piece 6 rotate synchronously;

[0032] The inner plate 2 of the head cap is fixedly installed on the inner side of the massage chair head cap 1, and an outer plate 3 of the head cap is provided on the outer side of the massage chair head cap 1. The outer plate 3 of the head cap is fixedly connected with the inner plate 2 of the head cap to clamp the massage chair head cap 1, and a head cap decoration 4 is fixedly installed on the side of the outer plate 3 of the head cap.
