In the solution of the present utility model a perforate can be arranged on installing plate, the mobile card that is made of the steel ball that connects on the fixing spring in lower end, the spring is arranged in the perforate, have and corresponding hole of mobile card position by the installing plate face at interior dial, all the bar hole constitutes an annulus.When mobile encoder, spring heads on steel ball and moves to another hole from a bar hole, thereby strengthens feel, and the imperceptible pin rod of people that making does not know to encode yet attempts the runin encoder slides to the state of level and smooth groove.

Can make key pass lock core in the technical solution of the utility model, between any two lock core elements, fix unblank a tongue dish identical with barrier structure, thereby by a coding lock that the key operated all size of more coding disk is arranged.Because key passes lock core, so the accent sign indicating number of key is to transfer sign indicating number forward from the coding disk of key root when unblanking.

The utility model has the advantages that: because lock has two-stage coding (lock core coding and encoder encodes), so the assembly coding scheme of whole lock improve greatly, thereby bigger safety factor is arranged.Simultaneously also can corresponding minimizing lock core element, with the lock that is applicable to that volume is less.The utility model not only can be with one the coding built-in of key operated corresponding all size, and can open padlock, bicycle lock of all size etc., has realized one the purpose of key operated ten million lock.

The utility model can further specify in conjunction with the accompanying drawings.
