A push-pull passage door lock comprising at least one handle, at least one lever, at least one rotating block, a slipping block, a latch bolt and a reset device for resetting the latch bolt. The lever, rotating block and slipping block are located inside the housing. The lever and rotating block are hinged to the housing. The rotating block comprises a rotation portion and a touch portion located at the two sides of an articulated shaft of the rotating block. One end of the lever is connected to the handle and the other end is adjacent the rotation portion. One end of the slipping block is connected to the latch bolt and the other end is adjacent the touch portion. The lever rotates the rotation portion of the rotating block, whereby the touch portion of the rotating block pushes up the slipping block and thereby retracts the latch bolt.
