Fig. 16 is a schematic structural view of the locking hook 32 in a locked state (90 degrees), fig. 17 is a schematic structural view of the locking hook in a handle state (180 degrees), and fig. 18 is a partial enlarged view of a portion iii in fig. 16. As shown in fig. 16-18, the locking hook 32 is movably connected at one end to the slider 31. As shown in fig. 12 and 16, the snap hook 32 includes a hook body 321, a hook rod 322, a hinge 323, a torsion spring 326, and an adjustment screw 324. The hook body 321 has a generally hook shape with one end connected to an end of the hook rod 322. The hook rod 322 has a substantially rod shape, and the other end is movably connected to the slider 31. The hinge 323 is movably hinged to the hook 321 by a pin 325 passing through the hook 321, the torsion spring 326 is sleeved on the pin 325, one end of the torsion spring 326 abuts against the hinge 323, and the other end abuts against the hook 321, so that the hinge 323 is parallel to the side of the base 11 facing the hook 321 in the open state (the state shown in fig. 17) and perpendicular to the side of the base 11 facing the hook 321 in the closed state (the state shown in fig. 16).

One end of the adjusting screw 324 passes through the slider 31 and abuts against the end of the locking hook 32, and the adjusting screw 324 is connected to the slider 31 by a thread for pushing the hook rod 322 to move when moving in a direction close to the luggage pull rod, so that the hook body 321 follows the hook rod 322 to move to lock the luggage pull rod. When the slider 31 is in place and the adjustment screw 324 is threaded, the latching hook 32 approaches and abuts the luggage case drawbar. Since the inner wall of the hook 321 near the slider 31 closely contacts the luggage handle as shown in fig. 27, the safety of the suitcase as a luggage seat is enhanced. When the adjusting screw 324 is screwed out, the locking hook 32 can be separated from the luggage pull rod by hand pulling, so that the suitcase can be conveniently taken out. The hinge 323 is in an open state when not being subjected to an opening force, and when the slider 31 is adjusted to the above-mentioned proper position, the hinge 323 and the hook 321 wrap the luggage pull rod together, and fix the luggage pull rod within the range of the latch hook 32, so that the connection between the luggage and the luggage pull rod is stable and reliable.

Fig. 19 is a partial enlarged view of the position I in fig. 5, and fig. 20 is a structural schematic view of the fixing bolt 33 in a state of being pulled out of the limiting hole 111. As shown in fig. 19, when the slider 31 needs to be fixed, the plug 331 is inserted through the slider 31 into the stopper hole 111 formed in the side surface of the base 11 facing the slider 31, so that the slider 31 can be fixed, and at this time, the slider 31 cannot slide along the slider slide groove 11 a. As shown in fig. 20, when the sliding block 31 needs to be moved, the end of the bolt 331 is disengaged from the limiting hole 111 by pulling the bolt 331, so that the sliding block 331 can slide in the sliding block sliding slot 11a again. At this time, the compression spring 332 is in a compressed state, and after the slider 31 moves to the target position, the latch 331 can be released, and the latch 331 can be inserted into the limiting hole 111 again under the action of the compression spring 332 to fix the slider 31 again.

Therefore, since the slider 31 can slide along the slider sliding groove 11a, the distance between the locking hooks 32 can be adjusted, and thus the locking hooks 32 can lock pull-rod type luggage cases of different sizes and models, and can be compatible with luggage cases of different models, and is suitable for pull rods of luggage cases with different widths.
