At this time, the Y second-level password scale 610 represents the passwords of the password disks 73 and 74 respectively, that is, the password for unlocking the lock 3. The locking plate 76 has a locking portion 761 pivotally disposed on the second pivot 72 and extending forwardly into the slot 51 of the locking hook 5, and a rear end of the locking portion 76 The arc bend extends and can be pivoted by the locking portion 761 to the pivoting portion 762. The reset # 77 is a torsion spring, and is elastically chased to the left side of the mounting plate 42 and the buckle portion 761 by the opposite ends thereof. The surface of the movable locking plate 76 is pivotally inserted into the slot 51 of the locking hook 5, and is biased to the right by the second limiting plate portion 422 of the mounting plate 42. As shown in FIGS. 3 and 4, the latch 8 has a grip portion 81, and a card portion 82 disposed in the insertion hole 414 of the bottom cover 413 and the through hole 420 of the mounting plate 42, and The housing 41 is inserted into the body 41, and the latching machine #7 is positioned at the insertion position of the double-selection open position and the detachment position of the housing 41 is changed. As shown in FIGS. It is shown that when the lock 3 is to be opened, the scale dial 61 and the latch mechanism 7 can be driven by turning the knob 62. When the latch mechanism 7 is in the latched position, at least the trays 73, 74 are closed. The alignment gaps 730 and 740 are not transferred to the predetermined position. At this time, the M331556 alignment portion 762 of the movable lock panel is limited by the outer peripheral surfaces of the password disks 73 and 74, and cannot be driven. The lock hook 5 is locked by the movable lock plate 76, and cannot be pulled to the right and left of the set body 41, and the movable lock plate 76 is correspondingly blocked directly above the through hole 420 of the mounting plate 42, so that the plug 8 is inserted. The card portion 82 cannot be fully inserted into the housing 41. When the first locking segment 52 of the locking hook 5 is to be opened to lock an annular article (not shown), for example, the first locking segment 52 is threaded with a chain that is locked to a chain. Turn the turn button 62 at least two turns to zero the code disks 73, 74. As shown in FIGS. 3, 7, and 8, immediately thereafter, the adjustment button 62 is further rotated to drive the first password disk 73 to continue to drive the second password disk 74 to rotate until the scale dial 61 represents the password of the second password disk 74. The code scale 61〇, the sub-reader buckles the scale 412, at this time, the second registration gap 74〇 has been turned toward the end of the alignment portion 762 of the movable lock plate 76. Then, the turn button 62' is reversely reversed to cause the first dial 73 to be disengaged from the second dial 100 and rotated by the month alone until the scale dial 61 represents the loose code scale 61G of the password of the first dial 73. The scale 412 is indicated. At this time, the first alignment notch 3〇 is vertically symmetrical with the second alignment notch 74〇. After the alignment gaps 73〇 and 74〇 are adjusted to the predetermined positions, the latch structure 7 is already in the one-side open position, and the user can pull the second lock of the lock hook 5 relative to the housing 41. The buckle 53 drives the end of the second locking segment 53 to move, and the body 4" is closed until the end of the first locking segment 52 is interlocked to the right to the first limiting portion 421 of the breaking plate 42. During the drawing process, the extension rod 51 of the X hook 5 will elastically push the movable lock plate 76 to the right. The M331556 card 4 P 761 drives the buckle 761 to pivot in the clockwise direction, and the alignment portion 762 is interlocked.

Then, the latch 8 can be pulled out of the housing 41. When the latching portion 761 of the movable locking plate 76 is again engaged with the latching slot 51 of the locking hook 5, the resetting member 77 automatically drives the movable locking plate back. The pendulum is reset, and at the same time, the lock hook 5 is reset to the left, and the second lock segment 53 is again inserted into the casing q. When normally used, the latch 8 is in the disengaged position, and only needs to be rotated to rotate the knob 62 to drive the latch mechanism 7 to change between the latching position and the one-side open position, so that only the second latching segment 53 of the latching hook 5 can be When the need to replace the item hooked to the first locking segment 52, the latch 8 must be inserted into the housing 41 to position the locking mechanism 7 in the dual-selection open position to enable the first locking segment. 52 is on. 11 M331556 In this embodiment, the latch mechanism 7 is only provided with two password disks 73, 74'. However, the number of the password disks 73, 74 is not limited thereto, and may be increased to several, thereby improving the lock 3 Security. In the above, the above-mentioned 'locking position of the locking hook $ card locking position through the locking mechanism 7, the one-side opening position of the _ 5 unidirectional opening, and the latch 8 can be positioned on the locking hook 5 The structural design of the change between the double-selection opening positions of the two-way opening makes the lock I 3 make the (four) more convenient and practical, and the item hooked to the first locking portion 52 of the locking hook 5 can be replaced at any time, and the card is The lock mechanism 7 cannot be automatically positioned in the double-selection open position, so the lock 3 can be relatively open to the second lock segment 53 in the case of ''', the flatness of the latch 8 can be relatively compared with the lock 3 The use of safety and convenience. Therefore, the purpose of the present invention can be achieved. The above-mentioned ones are only a preferred embodiment of the present invention, and the scope of the new implementation cannot be determined by (4) The simple equivalent changes and modifications made in the scope of patent application and the new description are still within the scope of this new patent.
