[0029] In this embodiment, the two rear connecting brackets 6 are symmetrically hinged on the rear side of the bottom of the sitting basin 5, and the two front connecting brackets 7 are symmetrically hinged on the front side of the bottom of the sitting basin 5. The front connecting brackets 7, the rear connecting brackets 6, the lifting arm 8, the motor bracket 10 and the screw rod 12 constitute a connecting rod driving mechanism, and the height adjustment of the sitting basin 5 is driven by the connecting rod driving mechanism.
