Wider range that arrangement of clutch can be selected for use, but all do not break away from essence of the present utility model, wherein preferred gear shifter yoke arrangement of clutch, this gear plectrum V shape arrangement of clutch comprises the gear 7 on the spindle nose surface of being fixed in turntable shaft 3 other ends, and the shift fork 9 that cooperates with gear 7 transmissions.

Transmission device can select for use rack-and-pinion transmission, worm and gear transmission, fork transmission etc. to become the kind of drive of rotating to translation, wherein preferred mode adopts gear ﹠ rack structure, this structure comprise the guide rail 10, the outside and guide rail 10 slidable fit that are fixed in cabinet door inner surface square shape slide plate 6, be fixed in slide plate 6 one inner side edges and with the adaptive latch 12 of the breach of minute dialer 5 sides and be fixed in slide plate 6 inboards and tooth bar 8, the opposite side of slide plate 6 and the dead bolt interlock adaptive with gear 7.

Guide rail 10 is fixed on the cabinet door inner surface of branch dialer 5 peripheries.

The obtained technological progress of the utility model is:

1, have only graduation mark on the manual turntable of the present utility model, and do not have numeral, owing to concrete number do not occur when unblanking, the numerical value that relies on operating personnel's heart to be remembered is as the criterion fully, can effectively prevent onlooker's stealing passwords;

2, adopt singlehanded wheel to unblank, realization is unblanked, the action of transcoding can not be carried out simultaneously, has effectively avoided runner to visit the possibility of sign indicating number;

3, adopt arrangement of clutch to realize runner, the combination of unblanking, structure more is tending towards compact and reasonable.
