[0030] It should be noted that if Figure 5 As shown, when the key 14 is not inserted, the movable bead 8 is located at the bottom of the first movable hole 7, the card block 16 abuts against the multiple lock core blocks 11, and does not fall into the multiple card slots 18. At this time, the card block 16 is locked in the first locking hole 19; when the key 14 is inserted into the key hole 6, the card block 16 is disengaged from the first locking hole 19 and abuts against the multiple card slots 18. When the key 14 is pulled out of the key hole 6, the card block 16 is disengaged from the card slot 18 and locked in the first locking hole 19;

[0031] When unlocking, as Figure 4 shown, insert the key 14 into the keyhole 6 so that the key 14 can lift multiple movable beads 8 located in multiple first movable holes 7. At this time, the multiple movable beads 8 fall into the tooth grooves of the key 14. At the same time, since the shifting block 13 is clamped in a corresponding shifting groove 12, multiple lock core blocks 11 can be lifted together, further enabling the locking block 16 to disengage from the first locking hole 19 under the push of the third elastic member 17 and abut against multiple card slots 18. At this time, the lock cylinder 2 can be rotated to unlock;

[0032] When locking, as Figure 5 shown, pull out the key 14 from the keyhole 6 so that the movable beads 8 fall to the bottom of the first movable holes 7 under the push of the second elastic member 9. At the same time, the multiple lock core blocks 11 also fall together, enabling the multiple lock core blocks 11 to push the locking block 16 out of the card slots 18 and lock it in the first locking hole 19.

At this time, the shifting block 13 disengages from the shifting groove 12. Further, take out the original key 14 and insert the new key 14 into the keyhole 6. Further, take out the key-changing member 21, and the upper lock core 4 is reset under the elastic force of the first elastic member 5, enabling the shifting block 13 to be re-clamped in a corresponding shifting groove 12, thus completing the key change;

[0034] It should be noted that each key 14 has tooth grooves of different heights. Each time the key 14 is inserted, the multiple movable beads 8 fall into the tooth grooves with different heights, but at this time the multiple lock core blocks 11 have the same height. Therefore, when changing the key 14, it is necessary to adjust the respective heights of the multiple movable beads 8 to adapt to the new key 14, and re-connect the multiple lock core blocks 11 with the same height to the multiple movable beads 8, thereby adjusting the clamping position between the multiple lock core blocks 11 and the multiple movable beads 8 to adapt to the new key 14;

[0035] It is worth mentioning that after the user changes the key 14, it is necessary to confirm whether the upper lock core 4 returns to the correct position. After confirmation, pull out the new key 14. Further, insert the new key 14 again and rotate to unlock. After no abnormality, turn the lock cylinder 2 to the original position through the new key 14, and then pull out the new key 14. At this time, it can be confirmed that the replacement of the new key 14 is successful.

[0036] In view of the deficiencies of the prior art, in the present invention, when the key 14 needs to be replaced, it is not necessary to disassemble the entire lock. Instead, the original key 14 and the key replacement part 21 are inserted in sequence, and then the new key 14 is replaced and the key replacement part 21 is pulled out, thereby completing the replacement of the key 14. Therefore, the present invention can realize the random replacement of multiple keys on the lock cylinder structure, achieve the usage purpose of customers in different scenarios, and make the lock cylinder structure have the advantage of being convenient for replacing keys.

[0037] As Figure 3 shown, in some embodiments, the upper lock cylinder 4 includes a first mounting seat 22, a second mounting seat 23, a fixing pin 25 and a clip spring 26.
