And 2, rotating the first key to drive the lock cylinder, the unlocking shaft and the lock tongue disc 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 communicated to be completely staggered and not communicated.

In the step 3, the step of mixing,the first key is continuously rotated to drive the lock core, the unlocking shaft and the lock tongue disc to synchronously rotate, clockwise rotates from a 90-degree angle to a 135-degree angle or anticlockwise rotates from a 270-degree angle to a 225-degree angle, in the process,in thatFirst authentication memberUnder the action of the force of the resetting component,the drive head on the unlocking shaft slides into the lower part from the high part of the annular slope rail, and meanwhile, the outer drive head on the lock tongue disc drives the lock tongue disc to move axially under the action of moving on the outer surrounding slope rail, and the unlocking shaft drives the verification shaft to synchronously move axially under the action of sliding of the linkage head on the verification shaft in the surrounding groove on the unlocking shaft, so that (a) verification tooth of the verification shaft originally is separated from the verification groove on the leaf or the marble and moves from the verification groove to the crossing direction, or (b) the verification shaft drives the upper marble to synchronously move axially so that the upper marble and the lower marble are staggered, or (c) the lower edge column on the verification edge column falls into the verification groove on the leaf, and the unlocking head is always positioned in the unlocking groove of the lock tongue disc.

And 4, continuing to rotate the first key to drive the lock cylinder and the unlocking shaft to synchronously rotate, clockwise rotating from 135 degrees to 225 degrees or anticlockwise rotating from 225 degrees to 135 degrees, and in the process of the distance, the lock tongue disc still rotates synchronously, so that the lock tongue disc is used for shifting a switch on equipment or a lock to unlock.

And 5, continuously rotating the first key to drive the lock cylinder and the unlocking shaft to synchronously rotate, wherein the lock cylinder and the unlocking shaft are driven to clockwise rotate from a 225-degree angle to a 270-degree angle or anticlockwise rotate from a 135-degree angle to a 90-degree angle, in the process, an inner driving head on the unlocking shaft is pushed by an inner surrounding slope rail to slide from a low position to a high position of the inner surrounding slope rail, meanwhile, the lock tongue disc moves leftwards and axially under the action of a resetting piece, the driving head slides from an outer surrounding slope rail to a low position, the unlocking shaft and the verifying shaft do resetting movement, so that (a) verifying tooth of the verifying shaft passes through a verifying groove on the leaf or the marble to be in a separated state, or (a) the verifying shaft drives the upper marble to synchronously move axially to enable the upper marble and the lower marble to coincide, or (a) the lower edge column on the verifying edge column leaves from a verifying groove on the leaf under the action of the resetting piece of the verifying edge 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 and the second verification component are not contacted, or the lower side column on the verification side column is not contacted with the leaf, or the upper pin tumbler slot and the lower pin tumbler slot are regarded as the same pin tumbler slot, the lower pin tumbler slot is not blocked when being stirred, the second verification component is stirred to be ineffectual, if the lock container 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 container and the second key slot of the lock shell are staggered and not communicated, the first key slot can not touch the second verification component in the second key slot to be stirred, and after the lock container is continuously rotated, because the inserted unaligned key or the unlocking slot on the master unlocking tool can not pass the final password verification of the second verification component originally, 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. under the interaction of the hidden verification device, the rotary unlocking device and the lock tongue disc, a non-original key or a master key is inserted, and when the leaf or the marble is exposed, the exploration is invalid, namely, the leaf or the marble is separated from the verification teeth of the unlocking shaft or the lower side column of the verification side column without contact; when the leaf or the marble is hidden, the master key can not directly contact the leaf or the marble for operation and exploration, so that the idle running result can be realized, and finally the marble or the leaf can not be stirred for complete unlocking.

2. Through the arrangement of the inner surrounding slope rail and the outer surrounding slope rail, the unlocking shaft can drive the lock tongue plate to uninterruptedly drive the lock or a switch on equipment by 360 degrees, so that unlocking is performed.

3. Through having set up hidden verification device in the lock shell, the verification piece among this hidden verification device can be set to marble joint verification, marble separation and reunion verification, blade axial verification or blade vertical verification, not only is applicable to the marble lock, still is applicable to the blade lock, and application scope is wide, and the practicality is strong, and the security performance is high, and theftproof nature is strong.

4. Through having set up relevant piece that resets for after the unblock or during the shutting, first verification component, second verify the component and can do the motion that resets fast, make the unblock in-process, under the effect of encircleing the ramp rail, first key not only can the reversal, also can continue to rotate, thereby extract the key.

5. The keys are set into a first key and a second key which can be separated, when the keys are inserted, an unlocking groove on the second key is transferred to a leaf or a marble of the second verification component and is restrained on the lock shell, and when the first key groove and the second key groove are staggered and not communicated by rotating the keys, namely the second key groove and the leaf or the marble of the second verification component are hidden, the second verification component and the first verification component can be allowed to carry out unlocking verification, if the keys are original keys, the verification is successful, and the keys can be unlocked by continuously rotating; if the key is not matched, the verification fails, and the lock cannot be unlocked only by idling after the key is continuously rotated. Therefore, the hidden verification can effectively stop technical unlocking, and the idling function effectively prevents violent twisting and damage, thereby effectively improving the anti-theft safety and the practicability.

6. Through being the arc at the drive head with the first junction of verifying the component, increase the lifting surface area, structural stability is stronger, and is difficult for bending deformation.
