Don't pull out or store the pull rod by brute force when it can't be elastic smoothly. Exerting force will only cause the pull rod to get stuck. When it gets stuck, the average user will continue to use brute force. This gesture will only make the tie rod stuck, resulting in failure to work and delay the trip. The correct way should be to add oil or vegetable oil to the joint of the pull rod. Basically, this problem can be easily solved by smoothing.
The pulley of the suitcase is broken.
The pulley is stuck, loose and falls off. When the suitcase is towed, if he feels that the pulley has obvious jamming feeling, he should also drop lubricating oil on the bearing of the wheel at this time. When the wheel is loose and may fall off, please don't continue to use the damaged wheel for traction, use the other wheel instead, or walk directly with the box. If conditions permit, tighten the wheel screws with the corresponding tools. If the screw is dropped and can't be found, it's easy to find what you need by seeing if there are any people or shops engaged in luggage maintenance near the construction site.
The box in the suitcase is broken.
Things are often worse when the box is broken. If it's a hard box, the damage is just Jamlom rupture. If it's not serious, you can repair it yourself with some universal glue and AB glue on the market. And the soft box is broken and needs maintenance. What needs to be weighed is that the brand box has been repaired by itself, so I'm afraid it can't be guaranteed any more.
