The present invention relates to a digital door lock, and more particularly, to a mortise lock of a digital door lock selectively used in a left open type door or a right open type door. The mortise lock of the digital door lock comprises: a mortise lock body having a deadbolt assembly horizontally moving by rotating power of a motor and a latch bolt assembly horizontally moving by rotating power of a door handle, the deadbolt assembly and the latch bolt assembly coupled to each other therein; and a first bracket fixed to a door by being coupled to one side of the mortise lock body while a dead bolt and a latch bolt pass through a through groove formed therein. The mortise lock of the digital door lock further comprises: a second bracket having the same shape as the first bracket, and coupled to the door together with the first bracket by a bolt; and a latch bolt assembly fixing portion fixing the latch bolt to the mortise lock body by allowing the latch bolt to protrude externally from the first bracket, such that the latch bolt rotatably coupled to an end of a moving shaft of the latch bolt assembly can be rotated or restrictively rotated according to whether the second bracket and the first bracket are coupled to each other. The latch bolt assembly fixing portion has the through groove through which the moving shaft of the latch bolt assembly passes, and has coupling protrusions coupled to fixing grooves formed in a cover of the mortise lock body. |
