PURPOSE: A structure for preventing separation of an open knob from a digital door lock is provided to prevent the separation of the open knob and an open knob assembly by connecting the open knob and the open knob assembly with an outside body through a coupler covering, a coupler covering bracket, and a mounting bracket. CONSTITUTION: An open knob(16) is installed at an inside body(10). The first coupler(18) is fixed to a shaft portion(16a) of the open knob(16). The second coupler(22) is coupled with a vertical rail portion(18a) of the first coupler(18). The third coupler(24) is coupled with a horizontal groove(22b) of the second coupler(22). A key tail(26) is installed at a shaft portion(24b) of the third coupler(24) in order to be inserted into a key groove(102) of a deadbolt assembly(100). A coupler covering(28) is installed at the first coupler(18). A coupler covering bracket(30) is combined with the first coupler(18) and mounted on the inside body(10). A mounting bracket(38) is combined with a stud(35) of an outside body.
