disclosed in U.S. Pat. No. 8,136,179 B2 and contains: a lift rod
fixed on a basin on which a faucet is mounted and configured to be
pulled upward and pressed downward; a drain base screwed with a
bottom of the basin and cooperating with a screwing element, the
draining base including an outlet defined on a top thereof and a
through hole formed on a peripheral side thereof; a connector
connected with the through hole of the drain base; a coupling rod
retained with a bottom of the lift rod and moving vertically in
response to the lift rod, the coupling rod including a plurality of
orifices formed thereon; a driving rod including a first segment, a
second segment, and a spherical ball adjacent to the first segment
and rotatably connected with the connector so as to form a fulcrum,
wherein the first segment extends into the drain base from the
through hole, the driving rod also includes plural fitting portions
arranged proximate to the second segment, and one of the plural
fitting portions selectively fits with one of the plurality of
orifices on the coupling rod, such that the driving rod moves
