When the cylinder B210 moves backwards, the triangular frame 301 moves along with the cylinder B210, so that the round bar C302 moves, and the rectangular block 303 moves, because the groove on the rectangular block 303 is set, after the rectangular block 303 moves for a short distance, the connecting bar B305 moves out of the heart-shaped V-shaped position, the rectangular block 303 cannot move backwards, because the set leg of the torsion spring rotates downwards, at this time, the triangular frame 301 can also move continuously, then the rectangular block 303 moves forwards, the round bar C302 moves forwards along with the rectangular block 303, and the long block 307 moves forwards and is clamped into the groove of the cylinder 209, so that the effect that the cylinder 209 cannot move is realized, when the cylinder 209 cannot move, the gear a203 cannot rotate, the gear B213 cannot rotate, and the locking tongue 211 cannot move, namely, the effect that the sub-lock mechanism 2 cannot be opened again after being opened once is realized.

In an alternative implementation manner of the embodiment of the present invention, the female lock mechanism 4 includes, in addition to the same components as those of the previous embodiment, a gear D401, a pulley 402, a semicircular hook 403, a cylinder C404, a gear D401 engaged with a gear C309; the cylinder C404 and the gear D401 are fixedly arranged; the pulley 402 and cylinder C404 are rotatably mounted; the semicircular hook 403 and one of the pulleys 402 are fixedly arranged; the cylinder C404 and the pulley 402 are both provided with rectangular grooves therein.

When the key B102 is inserted into the pulley 402, the key B102 is rotated so that the pulley 402 is rotated, and thus the semicircular hook 403 is rotated, and the semicircular hook 403 is caught in the keeper 103, at which time the primary and secondary locks cannot be unlocked even if the secondary lock mechanism 2 is unlocked.

Insert in drum C404 when key B102, thereby rotate drum C404 when inserting to end and rotate, thereby gear D401 rotates, thereby gear C309 rotates, thereby triangle cam 308 rotates, triangle cam 308 rotates and touches arc pole 306 when, arc pole 306 backward shift, thereby round bar C302 removes, thereby long block 307 backward shift, do not block cylinder 209, thereby round bar C302 backward shift rectangle piece 303 backward shift, connecting rod B305 will block the V-arrangement part that advances rectangle piece 303 heart shape recess at this time and make rectangle piece 303 get back to initial condition, realized that sub-lock mechanism 2 can normally open again.

The working principle is as follows:

when the key A101 is inserted into the lock case 1, the key A101 touches the round rod A201, then the key A101 is pushed to move along with the round rod A201, then the gear A203 and the telescopic column 204 on the round rod A201 move, the gear A203 moves to the gear B213 to be meshed with the gear B213, the round rod A201 moves along with the cylinder A205, so that the chute A207 rotates, the setting cylinder 209 of the rack group 208 moves downwards, so that the telescopic column 204 is pressed to retract into the cylinder B210, then the round rod A201 can rotate, when the gear A203 moves to the gear B213 to be meshed with the gear B213, the rotating key A101 rotates along with the round rod A201, the gear A203 on the round rod A201 rotates along with the gear B213, the round wheel 214 rotates along with the round rod B212, the bolt 211 moves, and the sub-lock mechanism 2 is opened.

Then the key A101 is rotated reversely, at this time, the snap ring 202 is not clamped on the clamping block on the round rod A201, the cylinder A205 moves backwards under the action of the spring, the cylinder 209 moves upwards to not clamp the cylinder B210, when the cylinder B210 moves backwards, the triangular frame 301 moves along with the cylinder B, so that the round rod C302 moves, the rectangular block 303 moves, because of the setting of the groove on the rectangular block 303, after the rectangular block 303 moves for a short distance, the connecting rod B305 moves out of the V-shaped position of the heart shape, the rectangular block 303 cannot move backwards, because the setting strand of the torsion spring rotates downwards, at this time, the triangular frame 301 can also continue to move, then the rectangular block 303 moves forwards along with the round rod C302, and along with the long block 307 moves forwards to be clamped into the groove of the cylinder 209, the effect that the cylinder 209 cannot move is achieved, when the cylinder 209 cannot move, the gear A203 cannot rotate along with the cylinder 209, and the gear B213 cannot rotate, therefore, the latch 211 cannot move, that is, the sub-lock mechanism 2 cannot be opened again after being opened once.
