Fully engaging with the chutes 414 of the first toothed members 41; after that, please refer to Figures 7, 16, and 17 to rotate the first matching key so that the positioning base positions the adjusting block to the locking case In the step (1), the first matching lock K1 is rotated to cause the positioning pin 50 to be snapped to the inner groove portion 322 of the positioning groove y of the adjusting block 3, thereby positioning the adjusting block 3〇 in the In the present embodiment, the first matching key K1 is rotated counterclockwise by 1 degree; then, referring to Figures 7, 18 and 19, in extracting the first matching key less (g), The first matching key K1 is extracted. In the embodiment, when the first matching key is extracted, the second toothed parts 42 of the toothed member sets 4 are received by the elastic members 43. The thrust is applied to the lowest position; then 'see Figures 7, 20 and 21, in the step (h) of inserting the second matching key into the lock, inserting a second matching key K2 into the lock π In the present embodiment, the second toothed member 42 of the set of toothed members is re-adjusted according to the height of the tooth peak of the second matching key Κ 2; then, please refer to No. 7, "囫, in the rotation of the second matching key to reset the adjustment block from the limit of the positioning pin, and to drive the first toothed member and the second toothed member to re-engage the step (1), 12 201009175 is to rotate the first The second matching key K2 is used to disengage the adjusting block 3 from the limit of the positioning pin 5, and the adjusting block 30 is reset by the pushing of the second elastic 62. The adjusting block 30 is reset during the process. The first toothed member 41 is re-engaged with the second toothed members 42. In the present embodiment, the second matching key 60 is rotated 90 degrees clockwise. In addition, please refer to Figures 24 and 25. 'After rotating the second matching key Κ2 clockwise, the lockable key lock system Will return to the normal operating state; finally, please refer to Figure 7, and then withdraw the second matching key to complete the key replacement step (j) to extract the second matching key Κ 2 to complete the key replacement procedure. The scope of the present invention is defined by the scope of the appended claims. Any changes and modifications made by those skilled in the art without departing from the spirit and scope of the invention are within the scope of the invention. .
