The locking relationship between the first lock body 3 and the second body 4 is released. And being affected by the movement of the first positioning pin 34, the connecting surface of the second positioning pin 47 and the third position pin 56 is moved to be located inside the third positioning hole 52, so that the second lock body 4 and the second The three lock bodies 5 are fixed together without any relative rotation. When the first lock body 3 is rotated by an angle with respect to the second lock body*, the through holes 31* are in communication with the holes 41 and cannot be blinded at the same time. 42 is completely coincident, because each through hole Η = the same angle of rotation 313 'must to match the blind hole 42 of the same angle of rotation angle (see Figure 1 〇, u), to form the through hole η and blind hole 42 overlapping with each other, ★ is also a paradox, only in the same as ®, although the first lock body 3 relative to the complex - miscellaneous r 1 #者〜士 for the brother-lock 4 rotation of a key The angle (about 18 degrees in the present embodiment), the 请 丨 τ | &) Hai 4 through hole 31 can coincide with the blind holes 42 having the same size of the rotation angle 413. Referring to Fig. 16 and Fig. 17, it is reported that τ笪,, ^ ± - Taguchi only, 1 and blind hole 42 are mutually recombined and connected to each other. At this time, the mother key 61 is taken out and located in the special blind hole. The inner gasket 46 of the 42 is inserted into the through hole 3 1 by the elastic 13 M288899 of the resilient elastic member 45. The user inserts another female key 61 into the slot 22 and rotates in the opposite direction. The key angle is extracted to the original position and the mother key 61 is pulled out. At this time, the first pins 33 may have different shades 63 (see FIG. 9) because the different mother keys 61 have different lengths, so that the first pins 33 are made. The position inside the corresponding through hole 31 is different, thereby achieving the purpose of replacing the key. After the process of replacing the remaining key is completed, only the missing groove and the position having the same degree and position as the replaced female key 61 are completed. The sub-key 62 of 63 can be inserted into the slot 22 to 'open or lock the action, and the original sub-key 62 cannot be used. The tea is shown in Fig. 18 and Fig. 19, and the user inserts the shell by using the replaced sub-key 62. After the slot 22 of the body 2, because the second groove 621 of the subkey & 62 Deep: Therefore, the interface between the first positioning pin 34 and the second positioning pin 47 moves inside the third clamping hole 32, and the first locking body 3 and the second locking body 4 are formed to be in a state of sorrow. When the lock is unlocked, the user rotates the sub-key 62 to rotate the first lock body 3 together with the second lock body 4 relative to the third lock body 5 to an unlockable angle to open the lock of the present invention, and then The sub-key 62 is rotated to the original locking angle to lock the new plastic lock and the sub-key 62 is pulled out. The second aspect of the present invention is achieved by the second latch 44 and the spacer 46 of the second lock body 4. - the cross-sectional shape of the through hole 31 of the lock body 3 is non-circular. On the other hand, the rotation angle 313 每一 of each of the through holes 3 ι of the first lock body 3 is not equal 'by the above two modes when rotating The master key 0 drives the first lock body 3 to rotate the change angle, and pulls out the female key Μ. The spacer 46 of the second lock body 4 receives the first elastic element 45.
