In particular, the operating lever 36 is composed of a rotating shaft portion 36a which is axially rotatable to the housing 30a, and an arm portion 36b extending from the rotating shaft portion 36a to move the dead bolt 32. Here, a fitting hole 36c through which the shaft device 26 of the inner body 20 is fitted is formed in the rotation shaft portion 36a.

According to the digital door lock having such a configuration, first, as in FIG. 1A, a button is operated outside the door D or a safety key is brought into contact with the contact portion 14 of the outer body 10 to input a signal. Then, the controller 22 of the inner body 20 determines whether the input signal is an authenticated signal. As a result of the determination, if the signal is authenticated, the controller 22 operates the driving motor 24. As the driving motor 24 is operated, the driving force of the driving motor 24 is transmitted to the shaft device 26 via a pair of bevel gears 28a and 28b, and the shaft device 26 to which power is transmitted rotates.

That is, the shaft device 26 for operating the dead bolt 32 is configured to fit through the fitting hole 36c of the operating lever 36, wherein the shaft device 26 is thin in the thickness of the door (D) In this case, it is configured to penetrate through the mortise 30 to protrude out of the door (D). Therefore, the endless particles can release the door D by forcibly manipulating the shaft device 26 protruding into the gap between the door D and the outer body 10.

On the other hand, when the thickness of the door D is thick, since the shaft device 26 is relatively short, the door D does not penetrate the mortise 30 and is located inside the fitting hole 36c. Therefore, the endless particles open the door D and the outer body 10 to expose the fitting hole 36c, and then insert the tool into the exposed fitting hole 36c to operate the operating lever 36 to open the door D. There is also the problem of resolving).

Therefore, the present invention has been devised to solve the conventional problems as described above, and its purpose is to prevent the shaft device for driving the dead bolt from protruding out of the door or immersing into the inside of the door. It is to provide a dead bolt drive shaft device of the door lock that can prevent the visitor from forcibly operating the shaft device or the operating lever.
