The present inventive concept relates to a push-pull door lock having a latch unit, which is provided inside a door so as to open/close the door from/to a door frame according to pushing/pulling of a handle. The latch unit comprises: a unit case which is provided to be embedded in the door so as to face the door frame; a movable bracket which is provided to be linearly movable in the unit case; an actuating cam which is provided in the movable bracket to be pivotable and is pivoted according to pushing/pulling of the handle so as to linearly move the movable bracket; an elastic member provided in the movable bracket to be elastically supported; a support block which is elastically supported by the elastic member and is provided to be latched by the movable bracket to be linearly movable along with the movable bracket; a connecting shaft provided through the support block; a latch bolt which is rotatably coupled to the connecting shaft and has an angle restriction groove formed in a portion where the connecting shaft is connected, in order to restrict the rotating angle thereof; and a fixed plate which has a through-hole through which the latch bolt passes and is fixedly coupled to the unit case.
