FIGS. 6-8 , theflexible clamper 50 is housed in theaccommodation groove 42 of theconnection seat 40 and includes aflexible clamping portion 51 in which thelift rod 30 is inserted. As illustrated inFIG. 11 , a top of theflexible clamper 50 is forced by an action force so as to flexibly retract and to clamp thelift rod 30 inward. As shown inFIG. 12 , after releasing theflexible clamper 50, theflexible clamper 50 expends outward and to unclamp thelift rod 30, hence thelift rod 30 is adjustably moved upward or downward. - With reference to
FIGS. 6, 9 and 10 , theadjustment member 60 is disposed on a top of theconnection seat 40 and is adjustably rotated among the at least one locking position P1 and the at least one unlocking position P2. When theadjustment member 60 is located at the at least one locking position P1, theflexible clamper 50 is forced by the action force. When theadjustment member 60 is located at the at least one unlocking position P2, theflexible clamper 50 is removed. - The
driving rod 70 is rotatably connected with theconnector 20 and a bottom of theconnection seat 40 so as to have a lever movement, when thelift rod 30 moves upward or downward with theconnection seat 40. - The
drain stopper 80 is secured on thedrain base 10 and includes a bottom end moving upward or downward in response to the lever movement of thedriving rod 70, such that theoutlet 11 of thedrain base 10 turns on/off, when the bottom end of thedrain stopper 70 moves upward or downward respectively. - The
accommodation groove 42 of theconnection seat 40 has twoopposite locking structures 43 formed on the peripheral wall thereof. Referring toFIG. 4 , each of the twoopposite locking structures 43 is a channel spirally and obliquely extending around the peripheral wall of theaccommodation groove 42, and each lockingstructure 43 has at least tworecesses 430 configured to form the at least one locking position P1 and the at least one unlocking position P2. - As shown in
FIGS. 6, 11 and 12 , theadjustment member 60 includes at least oneprotrusion 61, and when theadjustment member 60 is rotated, the at least oneprotrusion 61 is retained in at least tworecesses 430 respectively. - As illustrated in

FIGS. 4, 5 and 10 , each lockingstructure 43 has fourrecesses 430 which are afirst recess 432, asecond recess 433, athird recess 434, and afourth recess 435 formed from a bottom of each lockingstructure 43 to a top of each lockingstructure 43. Thefirst recess 432 is configured to retain alift rod 30 of a smallest diameter, thesecond recess 433 is configured to retain alift rod 30 of a small diameter, thethird recess 434 is configured to retain alift rod 30 of a large diameter or alift rod 30 of a largest diameter, and thefourth recess 435 is configured to remove thelift rod 30 of the largest diameter. - For example, the
lift rod 30 of 4 mm or thelift rod 30 of 5 mm are provided. When thelift rod 30 of 4 mm is provided, thesecond recess 433 has one of the at least one locking position P1 so that after one of the at least oneprotrusion 61 is retained in thesecond recess 433, the oneprotrusion 61 forces theflexible clamper 50, and theflexible clamping portion 51 retracts inward to clamp thelift rod 30 of 4 mm. - The
third recess 434 has one of the at least one unlocking position P2 so that after the oneprotrusion 61 is retained in thethird recess 433, it does not force theflexible clamper 50, and theflexible clamping portion 51 expends outward to unclamp thelift rod 30 of 4 mm. Thereafter, thelift rod 30 of 4 mm is moved upward or downward, and the oneprotrusion 61 of theadjustment member 60 is rotated to move back to thesecond recess 433 so that thelift rod 30 is retained, thus controlling an angle of the drivingrod 70 so as to adjust thedrain stopper 80 to a desired position. - When the
third recess 434 is configured to retain thelift rod 30 of 5 mm, theadjustment member 60 moves downward to force theflexible clamper 50. When thethird recess 434 is higher than thefourth recess 435, it is configured to remove thelift rod 30 of 5 mm, i.e., thethird recess 434 has the one unlocking position P2 so that after the oneprotrusion 61 is rotated into thefourth recess 433, it does not force theflexible clamper 50 downward, such that theflexible clamping portion 51 expands outward to unclamp thelift rod 30 of 5 mm, thus moving thelift rod 30 upward or downward. - Accordingly, the
third recess 434 is configured to remove thelift rod 30 of 4 mm or to retain thelift rod 30 of 5 mm, and thethird recess 434 has the one locking position P1 and the one unlocking position P2. In this embodiment, thethird recess 434 is configured to retain thelift rod 30 of 5 mm and thefourth recess 435 is configured to remove thelift 30 of 4 mm. Preferably, thefirst recess 432 is configured to retain anotherlift rod 30 of less than 4 mm, and thesecond recess 433 is configured to remove anotherlift 30 of less than 4 mm, thus fixing thelift rods 30 of various diameters. - When the at least one
protrusion 61 of theadjustment member 60 is located in the at least tworecesses 430 of different heights, a height difference between any two adjacent of the at least tworecesses 430 is 1.5 mm so that theflexible clamper 50 retains and removes thelift rod 30. - The at least two
recesses 430 windingly extend from the firstupper fringe 431 of each lockingstructure 43, so theadjustment member 60 is not rotated directly. For example, the at least oneprotrusion 61 of theadjustment member 60 is rotated into theother recesses 430 by pressing theadjustment member 60 downward so that theadjustment member 60 removes from the onerecess 430 and is rotated. When thelift rod 30 is retained, theflexible clamper 50 expends upward so that the at least oneprotrusion 61 is retained in theother recesses 430 tightly. - Accordingly, the
