By allowing the third actuating member 6 to avoid the unlocking member 9 instead of temporarily stopping the third actuating member 6 or the unlocking member 9 from being stopped, the abnormal passenger (such as a drunken passenger) can be prevented from being brute force. The hand pull cord 800 is pulled inside the hard pull door, causing a dangerous situation in which it can no longer be stopped and forcibly unlocked. The anti-missing device 100 of the present invention is that no matter how the passenger operates and how to rely on the brute force, the third actuating member 6 can only idle and does not touch the unlocking member 9 at all, so that the door lock system is not accidentally opened.

The precision of the operation of the anti-missing device is improved by the precise positioning of the positioning member 14 , because the first long groove 411 for driving the third actuator 6 to be retracted or re-expanded is opened in the first eccentric portion 41 . The first eccentric portion 41 is elastically abutted against the positioning member 14 by the abutting body 412 to produce a precise positioning effect, so that the first eccentric portion 41 is easily deformed due to the influence of the eccentrically driven shaft 61. The problem of misalignment was resolved.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalent structural changes of the present invention and the contents of the drawings are all included in the present invention.
