10. Finally, when the key is pulled out, the first pin 311 and the second pin 312 are both reset under the action of the pin springs, that is, the first pin 311 corresponds to the second pin 312, and at this time, a part of the plurality of second pins 312 is located in the second pin groove 41, and the other part is located in the first pin 311 groove.

11. The unlocking or locking is completed.

The anti-theft working principle of the embodiment I is as follows:

in the following description, the position change of each component in the unlocked or non-unlocked state will be also denoted by the reference numeral "r" … … ", and if not expressed in some steps, the position change will be consistent with the previous steps, and thus will not be described.

Firstly, when the lock is in an unlocked state, the marble/vane mounting hole 27 corresponds to the second marble groove 41, namely the first marble 311 corresponds to the second marble 312, at this time, a part of a plurality of second marbles 312 is positioned in the second marble groove 41, the other part is positioned in the first marble 311 groove, and if the first marble 311 is stirred, the second marble 312 can be pushed by the first marble 311 and retracts into the second marble groove 41; the first driving head 42 is positioned at the high position of the inner circle of the first driving annular slope rail 62; ③ the clutch driving head 43 is positioned in the thick driving groove 522 and far away from the outer circular wall; the second driving head 64 is positioned at the high position of the second driving annular slope rail 523; the 5 position of the lock tongue verification piece is close to the 12 wall of the inner shell; sixthly, the bolt verifying piece resetting element 5s is in a compressed state; the notch of the key slot 23 is located at the key insertion port 112; the latch 51 and the axial position reference line 500 of the switch are separated from each other (see fig. 7a), that is, the latch 51 is not in contact with the switch.

2. Then, when an unlocking tool such as the unauthorized key 100 or the master key is not rotated and inserted, it is necessary to push the first pin 311 by the unlocking tool such as the unauthorized key 100 or the master key to move the first pin 311 and the second pin 312 back and forth in the pin/vane mounting hole 2727 and the second pin groove 41, but the contact surfaces of all the first pins 311 and the second pins 312 cannot be made to be on the same horizontal plane, and "it is possible to see that the technical test unlocking is invalid".

3. Then, the lock is unlocked abnormally, when the knob lock core 2 is rotated clockwise or anticlockwise and is assumed to be 30 degrees, the clutch driving head 43 is positioned in the thick driving groove 522 and is far away from the outer circular wall, and drives the driving piece of the lock tongue 51 to rotate synchronously; the opening of the key slot 23 is separated from the key insertion opening 112 and completely enters the covering 111, that is, the covering 111 completely covers the opening of the key slot 23 (if there is a key shank slot, some embodiments completely cover), and "here, it can be seen that unlocking tools such as the non-original key 100, the master key, etc. cannot enter the key slot 23, and the technical trial unlocking is invalid.

4. When the knob lock core 2 is rotated clockwise or counterclockwise by an angle of 30 degrees, firstly, because the contact surfaces of the first pin 311 and the second pin 312 and the contact surfaces of the verification block 4 and the knob lock core 2 are not completely on the same horizontal plane, that is, the first pin 311 and the second pin 312 are clamped between the pin/vane mounting hole 27 and the second pin 312, the verification block 4 cannot drive the second pin 312 to synchronously and horizontally move, and therefore the first pin 311 and the second pin 312 cannot be horizontally separated; verifying that the block resetting element 4s is in a compressed state, and the outer circle of the first driving head 42 slides to a position above the lower part of the outer circle from the position of the upper part of the inner circle of the first driving annular slope rail 62; third, the clutch driving head 43 is located in the thick driving groove 522 and away from the outer circular wall.

5. Then, the lock is unlocked abnormally, and when the knob lock core 2 is continuously rotated clockwise or anticlockwise and is assumed to be 30 degrees, the clutch driving head 43 moves from the thick driving groove 522 to the position of the thin driving groove 521, and is not in the groove because of being far away from the outer circular wall; and fourthly, the second driving head 64 is moved away from the upper part of the second driving annular slope rail 523 from the high position to the low position.

6. Next, if the unlocking condition cannot be achieved and the knob cylinder 2 is further rotated clockwise or counterclockwise by 180 °, the locking bolt 51 cannot touch the switch during the rotation and the switch cannot be driven to be unlocked or locked (see fig. 7d) because the locking bolt 51 is separated from the axial position reference line 500 of the switch.

7. Then reset, when the knob lock core 2 is continuously rotated clockwise or counterclockwise and is assumed to be 30 degrees, the clutch driving head 43 moves from the position of the thin driving groove 521 to the position of the thick driving groove 522 and is far away from the outer circular wall; and fourthly, the second driving head 64 slides to a high position away from the upper part of the lower part of the second driving annular slope rail 523.

3. Then, the lock core 2 is rotated clockwise or counterclockwise to assume 30 ° and the notch of the key slot 23 leaves the key insertion opening 112 and completely enters the occultation 111, i.e. the occultation 111 completely covers the notch of the key slot 23 (if there is a key shank slot, it may be completely covered in some embodiments), and "here, it can be seen that unlocking tools such as the unauthorized key 100 and the master key cannot enter the key slot 23, and the technical test unlocking is invalid".

4. When the knob lock core 2 is rotated clockwise or counterclockwise by 30 ° following abnormal unlocking, firstly, because the contact surfaces of all the first pins 311 and the second pins 312 and the contact surface of the verification piece 52 and the knob lock core 2 are not completely on the same horizontal plane, that is, the first pins 311 and the second pins 312 are clamped between the pin/vane mounting holes 27 and the second pins 312, the locking bolt verification piece 5 cannot drive the second pins 312 to synchronously and horizontally move, and therefore the first pins 311 and the second pins 312 cannot be horizontally separated. Secondly, in the second driving device 82, the second driving ball resetting element 82s is changed into a compression state from an extension state, and the second driving ball 822 slides from the lower part of the second driving annular slope rail 820 to the higher part

5. Then, the lock is unlocked abnormally, the knob core 2 is continuously rotated clockwise or counterclockwise by an angle of 30 °, then the unlocking condition cannot be achieved, and when the knob core 2 is continuously rotated clockwise or counterclockwise by an angle of 240 °, the locking bolt 51 is separated from the axial position reference line 500 of the switch (see fig. 7d), and the switch cannot be driven to unlock or lock.
