The invention discloses a door lock equipped with a pull-push handle. The present invention relates to a door lock which rotates a handle of the door lock forwards or backwards by pulling or pushing the handle forwards or backwards without horizontally rotating the handle of the door lock to input a latch bolt of the door lock to open a door. The door lock introduces a pinion having a sawtooth portion formed on an external circumference of one side thereof to install the handle by switching a pull-push direction of the handle to be matched with an open direction of the door; and first and second elevation racks in which corresponding sawtooth portions, which can be engaged with the sawtooth portion, are formed in an opposite direction to replace the first and second elevation racks when the door lock is coupled by changing a direction of the pinion to allow the sawtooth portion to face one side or the other side, thus switching a pull-push direction of the handle.
