After the user changes the locking bead group arrangement of the lock core assembly 30, the locking teeth 73 of each unlocking block 70 on the key must be changed together. Referring to FIG. 10 and FIG. 11, the positioning screw 53 is first removed. The nut 511 is formed in a rotatable state, and the user rotates the nut 511 by hand, and the core post 60 is transmitted through the interaction between the internal thread of the inner screw hole 512 and the external thread of the joint portion 61 of the stem 60. Moving away from the grip 50, the latching recess 621 of the moved stem 60 can move away from the tab 71 of the adjacent unlocking block 70, and the mutually interlocking unlocking blocks 70 can be separated from each other. After the user adjusts the alignment mark 730 of the unlocking block 70 to the lock bead set corresponding to the lock core assembly 30, the nut 511 is reversely rotated to move the stem 60 toward the grip 50, and The latching recesses 621 are inserted into the projections 71 of the adjacent unlocking blocks 70, and the unlocking blocks 70 are fitted to each other. Finally, the positioning screws 53 are assembled to the grips 50 to position the nuts 511. Forms a state in which it cannot be rotated. At this time, the key can be unlocked or locked according to the adjusted lock. Since the key of the present invention is designed to change the arrangement of the lock teeth 73, it is possible to provide the key through the change of the lock teeth 73 to adjust the lock corresponding to the lock bead array arrangement to achieve unlocking or locking, only when the key is lost When such a type of key is purchased, the matching mark 312 arranged in the lock bead group is arranged to match the registration mark 730 of the lock tooth 73 of the lock, and the key can be held. Unlocking or blocking provides considerable convenience in use.
