---the deadlock mechanism that links with the cable wire ring is by finer wire, deadlock body, anti-pin, the spring of opening, and the pin tongue is formed, and the deadlock body is fixed on the inwall of door leaf, and it is corresponding with the lock tongue slot on the keeper frame that dead bolt is fixed on the root of keeper frame.

---the axle head of the dial shaft that links to each other with digital dial is equipped with the interlock dish that links to each other with toothed disc, and the latch that is complementary with toothed disc is contained on the keeper frame, and the rectangular channel on the toothed disc is corresponding with the number at quarter on the digital dial.

The protected apron of the utility model deadlock mechanism is fixed between deadlock body and the door leaf, prevents boring.

Protective jacket of the present utility model inboard is provided with step trough, and the spring pressuring plate of cable wire ring and fixing tightwire ring is housed in the groove.
