The group 60 is disposed on the first toothed member chute 25 of the lock 20 and the second toothed member chute 41 of the slider 40, and each of the toothed member sets 60 includes a first tooth. a bit member 61, a second toothed member 62 that can be sprayed with the first bit 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 6丨, the second toothed member and the 5th elastic member 63 are configured to 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 shows a state in which a key is inserted into the keyhole 42 and is not inserted into the position. In the present embodiment, the key 70 is inserted into the keyhole 42 and is not inserted into the description. The key 70 is not inserted into the bottom, so that the one end portion 70a of the key 7〇 does not abut the tapered portion 5〇& of the driving member 5, at which time the tapered portion 50a of the driving member 50 receives the lock. The thrust of the bead spring 92 is maintained at the lowest position, and the upper locking bead 91 and the limiting member 3 are not at the rotating interface. Therefore, the movement of the slider 4 and the rotation of the locking arm 2 can be restricted; Please refer to FIG. 7B. When the key 7〇 is completely inserted into the bottom, the end of the key 70 is “〇”, and the cone 5 of the driving member 5 is pushed to displace the driving member 50. With the visitor 'moving the limit member 30 and the upper locking bead to the rotating interface, please refer to the 7C figure. When a thrust is applied to the key 7 , the slider 40 is dislocated μ 〜 , detached from the limit of the 3 〇 限 限 而 而 而 § § 带 带 带 带 带 带 带 带 带 带 带 带 带 轴向 轴向 轴向 轴向 轴向Turning the key 7〇201009176 The lock 20 can also be rotated by the limit of the lock bead 9 1 , and the present invention ensures the key by the action of the limit member 30 and the drive member 50. The 70 series performs a key change operation while being inserted. Ο ❹ In addition, please refer to Figures 8, 9, 10, 11 and 12Α to 12C. The present invention is equally applicable to a special key system. The replacement key operation of the special key system must be dedicated to a recognition recess 80a. The key can be achieved by 8". First, please refer to paragraphs 8, 9, 1 and ,. In this embodiment, the height of the enemies 30 and the height of the entrainment member 50 are based on the identification of the special key 80. The depth of the slot 8〇a is adjusted to control the taper 5〇a of the driver member 50 to fall into the identification recess 8〇a, so that the limiting member 3〇 and the upper locking bead 91 are located on the rotating interface. Next, referring to FIG. 12A, when the keyhole 528 of the slider 40 is inserted into the bottom of the slider 40 and inserted into the bottom, since the general key gauge does not recognize the groove, it cannot be made by the X-carrying member 50. The limiting member 3〇 and the locking bead 9 i are located at the rotating interface #, so the key replacement procedure cannot be entered; otherwise, please refer to the coffee diagram, when the special (4) key 8G is inserted into the keyhole of the slider 4G. 42 and when inserted in the end, the cone pool of the driver 5G will fall into the identification groove 80 of the special key 〇 a' At the same time, the limiting member 3〇 and the locking bead η= will move to the rotating interface, please refer to the figure, when the special lock & 8〇 applies - thrust, the slider 40 is disengaged The limit of the limit member 3= is axially moved together with the driving #50_, and similarly, when the special key is 8 〇, the anchor// 疋 is transferred, and the lock 20 is taken out of the locked bead. The limit of 91 can also be rotated, and the borrowing of the present invention by the limiting member 3 and the driving member 50 can be performed with the special key 80 for the key to be used for the key replacement operation 10 201009176 The purpose. The scope of the present invention is defined by the scope of the appended claims, and any changes and modifications made by those skilled in the art without departing from the scope of the invention are protected by the present invention. ^ [Simple diagram description]
