A sink drain may include a drainage tube, a strainer, an O-shaped sealing pad, a drain cover, and a general bolt. The drainage tube has a blocking edge at an upper end thereof, and a thread nut is disposed on the drainage tube. The strainer has a cup-shaped main body, and a thread portion is formed on the outer periphery of a lower section of the main body. The thread nut of the drainage tube is engaged with the thread portion of the strainer to complete the connection between the drainage tube and the strainer. The sealing pad, which is elastically deformable, has a first section and a second section, and the first section having a larger diameter than the second section is located above the second section. The drain cover with a second O-ring is downwardly put in a second drainage hole of a sink.
