step 1, firstly, inserting an original key (namely a first key and a second key) into key grooves in a lock shell and a lock liner, shifting a blade or a marble by an unlocking groove on the second key, when the key is completely inserted into the key grooves (namely the first key is inserted into the first key groove and the second key is inserted into the second key groove), completely clamping the second key into the second key groove, wherein the second key is immovable (namely the second key is restrained on the lock shell), and at the moment, driving parts of all the blades or marbles are completely matched with the corresponding unlocking grooves, and simultaneously, a verification groove of the blade or the marble is completely matched with a verification tooth of a verification shaft; or (II) the upper marble is completely positioned in the upper marble groove and the lower marble is completely positioned in the lower marble groove; or (III) the lower side column of the verification side column is completely matched with the verification groove.

And 2, rotating the first key to drive the lock core and the unlocking shaft to synchronously rotate, clockwise rotating from an angle of 0 degree to an angle of 90 degrees or anticlockwise rotating from an angle of 0 degree to an angle of 270 degrees, wherein in the process, the first key and the second key are completely overlapped to be completely staggered (namely separated), namely the first key slot and the second key slot are completely staggered and not communicated.

And step 3, continuing to rotate the first key to drive the lock core and the unlocking shaft to synchronously rotate, clockwise rotating from a 90-degree angle to a 135-degree angle or anticlockwise rotating from a 270-degree angle to a 225-degree angle,in thatFirst authentication memberUnder the action of the force of the resetting component,the driving head on the unlocking shaft slides into the lower part from the high part of the annular slope rail, and meanwhile, the unlocking shaft drives the verification shaft to synchronously and axially move under the sliding action of the linkage head on the verification shaft in the annular groove on the unlocking shaft, so that the verification teeth of the original verification shaft are separated from the verification grooves on the blades or the marbles and move from approaching to crossing; or (II) the first verification component drives the upper marbles to synchronously and axially move so that the upper marbles and the lower marbles are staggered; or (III) the lower edge column on the verification edge column falls into the verification groove on the leaf,

step 4, continuing to rotate the first key to drive the lock cylinder and the unlocking shaft to synchronously rotate, wherein the angle is from 135 degrees to 225 degrees clockwise or from 225 degrees to 135 degrees anticlockwise, and in the process of the distance, the extended unlocking head and the lock cylinder can synchronously rotate to also stir some equipment or a lock which needs to rotate to stir the switch to unlock, and then the equipment or the lock is stirred by the unlocking head to unlock; or the unlocking head is inserted into the unlocking part of the spring bolt disc, and then the spring bolt disc is driven to shift some equipment or lockset which needs to rotate to shift the switch to unlock.

And 5, continuously rotating the first key to drive the lock cylinder and the unlocking shaft to synchronously rotate, wherein the clockwise angle is from 225 degrees to 270 degrees or the counterclockwise angle is from 135 degrees to 90 degrees, in the process, the driving head on the unlocking shaft is pushed by the annular slope rail to slide from the lower part of the annular slope rail to the higher part, and meanwhile, the unlocking shaft and the verification shaft do reset motion, so that (a) verification teeth of the verification shaft pass through the verification grooves on the leaf or the marble to be in a separation state, or (b) the verification shaft drives the upper marble to synchronously axially move to enable the upper marble and the lower marble to be superposed, or (c) the lower side column on the verification side column leaves from the verification grooves on the leaf under the action of a reset element of the verification side column.

And 6, continuously rotating the first key to drive the lock core and the unlocking shaft to synchronously rotate, wherein the clockwise angle is from 270 degrees to 0 degrees or the counterclockwise angle is from 90 degrees to 0 degrees, and in the process, the first key and the second key are completely staggered to be completely overlapped, namely the first key groove and the second key groove are completely staggered and communicated with each other.

And 7, finally, pulling out the key to complete unlocking or locking.

It should be noted that the rotation angle mentioned in the unlocking step is only used for enhancing understanding, and it is not stated that the unlocking condition must be achieved by this angle, and the unlocking step uses a rotation of 360 ° for 1 week to complete unlocking or locking, but it is also possible to reverse to 0 ° after half a week or less, and such an operation can also achieve the completion of unlocking or locking.

When the first key slot and the second key slot are not completely staggered, because the verification teeth on the verification shaft are not contacted with the marble or the leaf, (two) the lower side column on the verification side column is not contacted with the leaf, (three) the upper marble slot and the lower marble slot are regarded as the same marble slot, the lower marble slot is not blocked when the lower marble slot is shifted, the second verification component is shifted to be ineffectual, if the lock liner is continuously rotated to ensure that the first key slot and the second key slot are completely staggered, the first key slot of the lock liner and the second key slot of the lock shell are staggered and not communicated, the second verification component in the second key slot can not be touched through the first key slot to be shifted, after the lock liner is continuously rotated, because the original inserted non-original key or the unlocking slot on the master unlocking tool can not pass the final password verification of the second verification component, therefore, the rotary unlocking device and the hidden verification device cannot axially move to enable the unlocking head to axially move for unlocking, and finally only can idle.

By adopting the technical scheme, the invention has the beneficial effects that:

1. the hidden verification device and the rotary unlocking device are arranged in the lock shell, so that an unary key or a universal key is inserted, when the blades or the marbles are exposed, the probing is invalid, namely, the blades or the marbles are separated from the unlocking shaft or the verification side column without contact, when the blades or the marbles are hidden, the universal key cannot directly contact the blades or the marbles to perform operation probing, only the idling result can be realized, and finally the marbles or the blades cannot be stirred to perform complete unlocking.

2.
