Technology unlocking method and prevention principle:

Toothed tools such as prevention are unblanked:

When unblanking Deng toothed tool, be with instrument pellet shot from a slingshot all to be released lock core, lock core rotates freely and unblanks.When sealing with bolt, with bolt precession appropriate depth, guaranteeing that second pellet shot from a slingshot can enter in the lock body passage fully exceeds, and no longer leaves unnecessary space, can not allow first pellet shot from a slingshot enter so that unblank, and then stops it to unblank.

When stoping master key to be unblanked:

When master key is unblanked, want about 10 ° of clockwise shearing lock cores earlier, to push down second pellet shot from a slingshot, and to guarantee to release second pellet shot from a slingshot, after using technology of the present utility model, the twisting angle of lock core need just can be pushed down second pellet shot from a slingshot greatlyyer, makes the bigger of second pellet shot from a slingshot inclination.At this moment because the second pellet shot from a slingshot front wing is stuck in dislocation place, just can not release pellet shot from a slingshot.Because the principle of active force and reaction force if release pellet shot from a slingshot, just must be turned round, and is alignd with the lock body passway in the lock core passway, at this moment the dislocation difference is 0, and the pellet shot from a slingshot that is pushed out can also enter in the lock core easily, just can not unblank.

Prevention is knocked or the pistol type instrument is unblanked:

Hammering method: after an instrument that is similar to key inserted lock core, reverse to clockwise direction slightly, firmly knock this unlocking tool then downwards, lock and promptly open.Second pellet shot from a slingshot of the present utility model central axis when lock core twists points to and is offset, under the power in the first pellet shot from a slingshot transmission and the acting in conjunction of spring, second pellet shot from a slingshot or front wing are stuck in dislocation place, or rear wing withstands on the sawtooth of passage, or both of these case takes place simultaneously, thereby can not release lock core to second pellet shot from a slingshot, therefore can not unblank.
