The single rocker arm 61 opens or blocks the air valve inlet 251 or the air valve outlet 252 within the extension and contraction range of the shape memory wire 64, and uses the support column 27 of the single rocker arm 61 as a support point to swing horizontally within the massage air valve cavity 25; the reset elastic member 53 here can be a spring or a torsion spring or other elastic members that perform the above functions.
