The lift block 18 can be adjusted up and down so that it can be relatively fixed by the action of the electromagnetic plate 22, and the drive shaft 36 is rotated by a key, whereby the rotary gear 35, the rotary gear 34, and the lock shaft are rotated. 45 is rotated, thereby rotating the push rod 11 fixedly installed on the lock shaft 45, thereby lowering the moving plate 26 and the ladder block 37, thereby lowering the moving block 27. When the moving block 27 comes into contact with the support plate 21, the moving groove 28 faces the slide chamber 46, the geared block 37 continuously descends, and the moving block 27 stops descending. The gear-shaped rod 29 moves toward one side, the moving spring 39 is pulled, and the second electromagnetic block 40 is fixedly connected so as to face the slide block 19, and the drive shaft 36 is returned. Then, the above-mentioned movements are interlocked to return, and when the ladder-shaped rod 29 returns by the action of the moving spring 39, the slide block 19 moves in conjunction with each other, thereby pulling the rope 20 and thereby pulling the rope 20. When the lock block 3 separates from the lock groove 4, the second electromagnetic block 40 moves into the moving groove 28, and the moving block 27 is pushed back through the elevating spring 6, the lock block 3 moves. It returns by the action of the return spring 5.

If the key is forgotten, the rotation shaft 32 is rotated by memorizing the position of the lift block 18, thereby rotating the push rod 11 in the middle, whereby the elevating block 13 is lowered and interlocked, and the first When the one electric magnet 14 and the slide block 19 face each other, the elevating block 13 is suspended without moving, and the slide block 19 moves around by the action of the first electric magnet 14, and the lock block 3 is passed through the rope 20. The slide block 19 moves until it is separated from the lock groove 4, thereby completing the opening of the door, returning the rotating shaft 32, and then returning the device by the action of a spring.

The beneficial effect of the present invention is: The device is simple in structure, convenient to operate, and on the premise that it does not affect the operation of the door lock, it improves the safety of the door lock and does not have to pry open the lock. Unlocking becomes convenient at the same time as ensuring the safety of the lock.

The above is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited to this. Changes and replacements that come to mind through all creative labor are covered by the scope of the invention. Therefore, the scope of protection of the present invention is based on the scope of protection in which the request for rights is limited.
