Mortise capable of limit insertion of main latch and provided with sub latch

The present invention relates to a mortise capable of limit insertion of a main latch and provided with a sub latch, including a dead bolt, a sub latch, a main latch, and a dead bolt operating unit tolock and unlock a door. Specifically, the mortise permits insertion of a latch bolt when the door is open and blocks the insertion of the latch bolt when the door is locked. So, the latch bolt performs a locking function of the door with the dead bolt so that security of the mortise can be improved. To achieve the same, a pressing unit of the sub latch and a pressing protrusion of a latch cam permit a backward movement of a latch transfer while the sub latch half-protrudes due to a closure of the door. So, while the latch stopper rotates in one direction, a locking protrusion blocks the insertion of the latch bolt. When the insertion and the withdrawal of the sub latch are completed as the door is opened and closed by a handle, the pressing unit or the pressing protrusion moves the latchtransfer forward. So, the latch stopper rotates in the other direction, and the locking protrusion permits the insertion of the latch bolt, so that when a door is closed, the main latch is inhibited to be inserted by the mortise; and the main latch is inserted only if the door is opened, so that along with the dead bolt, the main latch itself has a locking function, thereby enhancing security.
