The key cover 31 is pressed inward to make the elastic member 51 store energy, and the rebound energy can effectively reset the key cover 31.

More preferably, the outer side of the foot main body 221 is coupled with a decorative cover r by a screw, and the outer surface of the decorative cover r does not exceed the outer side of the first circular body 121.

The bottom of the decorative cover r is provided with an arc bottom wall r2 to be attached to the third annular peripheral wall d2 of the third circular body 222. Thereby ensuring the beautiful appearance of the supporting leg assembly 20 and forming effective fitting relation with the locking switch 30, and enabling the whole bath frame adjusting mechanism to have more integrity and consistency.
