Claim:
1. A pop-up drain stopper linkage assembly adapted for a basin and comprising: a lift rod extending through a basin, and the lift rod being pulled upward or pressed downward and being rotated by a user after extending through the basin; a drain base disposed on the basin and including an outlet; a connector fixed on the drain base; a threaded rod including a top end connected with a bottom end of the lift rod, and the threaded rod moving upward and downward and rotating in response to the lift rod; a threaded sleeve screwing with and moving upward and downward in response to the threaded rod, and the threaded sleeve including a first retaining portion arranged on an outer wall thereof, wherein the threaded rod inserts through the threaded sleeve; a driving rod including a first segment, a second segment, a spherical ball formed adjacent to the first segment and rotatably connecting with the connector so as to form a fulcrum, and plural second retaining portions horizontally arranged proximate to the second segment so that the first retaining portion of the threaded sleeve selectively retains with one of the plural second retaining portions, such that the driving rod causes a lever movement along the fulcrum as the threaded rod moves upward and downward; a drain stopper secured on the drain base and including a bottom end moving upward and downward in response to the lever movement of the driving rod, such that the outlet of the drain base turns on/off as the bottom end of the drain stopper moves upward and downward respectively; wherein one of the first retaining portion and the second retaining portion is a column, and the other of the first retaining portion and the second retaining portion is a locking hole; wherein the first retaining portion is a column extending outwardly from the outer wall of the threaded sleeve, and the plural second retaining portions are plural locking holes respectively so that the column selectively retains with one of the plural locking holes.
