Both the first latch body 11 and the second latch body 12 have protruding locking portions 102 on the side away from the hinge. The locking portion 102 of the first latch body 11 has a latching tongue (not shown) controlled by a lock cylinder 103. The locking portion 102 of the second latch body 12 has a locking groove 105 that adapts to and locks the latching tongue (not shown) to restrict the opening of the first latch body 11 and the second latch body 12. The locking portions 102 of the first latch body 11 and the second latch body 12... Each of the fixed parts 102 is provided with an anti-detachment part 106; it also includes a co-locking member 13 and a co-locking slider 14 that can slide relative to the co-locking member 13.
