In the present embodiment, the driving member 50 is a tapered locking bead, and the driving member 50 has a tapered portion 50 a of each of the keyholes 42 of the slider 40. The group 60 is disposed on the first toothed member chute 25 of the lock 20 and the second toothed chute 41 of the slider 40, and each of the tooth sets 60 includes a first a toothed member 6 1 , a second toothed member 62 that can be in contact with the first toothed member 61 , and an elastic member 63 disposed between the first toothed member 61 and the second toothed member 62 . In this embodiment, the elastic member 63 is a spring, and the first toothed member 61, the second toothed member 62, and the nano-elastic member 63 can form a height-adjustable locking bead.

See Figure 7a through 7C for the foolproof effect of the replaceable key lock. First, please refer to FIG. 7A, which is a schematic diagram showing a state in which a key 7 is inserted into the keyhole 42 and is not inserted into the positioning. In the embodiment, the key 70 is inserted into the keyhole 42 and is not inserted into the description. Since the key 70 is not inserted into the bottom, one end portion 7〇a of the key 7〇 does not abut the tapered portion 5〇a of the driving member 50. At this time, the tapered portion 5Qa of the driving member 50 is subjected to The thrust of the lock bead spring 92 is maintained at the lowest position, and the upper locking bead 91 and the limiting member 3 () are at the rotating interface. Therefore, the movement of the slider 40 and the rotation of the lock 20 can be restricted; Anti-T 'Please refer to 帛7B ® 'When the lock 87G is fully inserted into the end, the end 胄 70a of the key 70 will push the cone to push the cone to displace and drive the driver 50 The limiting member 3q and the locking bead move to the rotating interface, and when the 7n applies a thrust to the money, the slider 40 can be removed together with the limit of the limiting member 3Q.

5海带动件5 0——起起向铭 without rri JM , I move the same, when the key is rotated 7〇, 9 1345605 The lock 20 can also be rotated by the limit of the upper lock bead 91 In the invention, by the action of the limiting member 30 and the driving member 50, it is ensured that the key 70 is locked in the state of being inserted into the bottom.

In addition, please refer to Figures 8, 9, 1 and 11 and 12A to 12C. The present invention is also applicable to a special locking system. The replacement key operation of the special key system must be dedicated to a recognition recess 80a. The key 8 can be achieved. First, please refer to Figures 8, 9, 10 and 11. In the present embodiment, the height of the limiting member 30 and the driving member 50 is based on the identification groove of the special key 80. The depth of the 8〇a is adjusted to control the tapered portion 50a of the driving member 50 to fall into the identification recess 80a, so that the limiting member 3 and the upper locking bead 91 are located on the rotating interface, and then, please Referring to FIG. 12, when the keyhole κ of the slider 4 is inserted into the bottom of the slider 4 by the general key κ and is inserted into the bottom, since the general key κ does not recognize the groove, the limit cannot be made by the carrier 50. The member 3〇 and the locking bead 91 are located at the rotating interface j, so the key replacement procedure cannot be performed; otherwise, referring to Fig. 12, the special key 80 of the field is inserted into the keyhole 42 of the slider 4 and inserted into the bottom J. When the tapered portion 5〇a of the driving member 50 falls into the special key 80, the identification The slot 80a, at the same time, the limiting member 3〇 and the locking bead will move to the rotating interface. Referring to FIG. 12C, when the special locking position is applied to the thrust, the slider is disengaged from the The limit of the limiting member 3〇 can be axially moved along with the driving member 5〇, and similarly, when the special key 80 is rotated, the locking device 20 βει κ? private, also 7, 1 1-20 Because the limit of the locking bead 91 is removed, the invention can be rotated. The invention is achieved by the hunting of the 6-shaped limiting member 30 and the driving member 50 to achieve the special key 8 mussels, 80 The purpose of the key change operation 1345605 can be performed. The scope of the present invention is defined by the scope of the appended claims.
