The apparatus includes: first and second door handles which are configured to be pushed or pulled; a moving unit which is coupled to the first and second door handles; a rotating unit which is rotatably coupled on a rotating shaft and locked to the moving unit so that when the moving unit horizontally moves, the rotating unit rotates around the rotating shaft; an actuating member which is locked to the rotating unit and moved in a direction perpendicular to a direction in which the moving unit moves; a latch unit which is fixed to the actuating member so that the latch unit is ejected from or retracted into the door by the movement of the actuating member; and a restoring spring which is wrapped around the rotating shaft and fixed to the door lock housing and the rotating unit.
