Description

technical field [0001] The invention relates to the technical field of luggage accessories, in particular to a luggage pull rod whose length can be adjusted arbitrarily. Background technique [0002] Bags are a very common tool used in daily life, especially bags with pull rods. Luggages with pull rods on the market generally include a handle, a fixed tube and a telescopic movable tube, wherein a positioning structure is arranged between the fixed tube and the telescopic movable tube to adjust the length of the pull rod by restricting the telescopic movable tube. The positioning structure is generally provided with protrusions and slots that cooperate with each other to clamp and position on the fixed tube and the telescopic moving tube respectively. Although this kind of trolley case adopting the positioning structure of protrusions and slots can also realize the adjustment of the length of the trolley, but because the slots in the trolley are arranged at intervals, the tr...
