AI Technical Summary
In existing telescopic tube structures, the protruding end is easily pressed into the inner wall of the inner tube and gets stuck, causing the length adjustment of the inner and outer tubes to fail.
Multiple holes are set on the outer tube and the inner tube, and spring clips and sleeves are installed on the inner tube. Elastic elements and limiting structures are used to prevent the ejector end from getting stuck. Step structure and sliding connection are used to prevent getting stuck, so as to achieve smooth ejection of the ejector end.
It effectively prevents the ejector end from getting stuck in the inner tube hole, ensuring smooth length adjustment of the inner and outer tubes and solving the jamming problem.

Abstract
Claims
1. A non-jamming telescopic tube structure, characterized by, It includes an inner tube and an outer tube that can extend and retract from each other. The outer tube has at least two first holes at different heights on its wall. The inner tube has at least one second hole on its wall, and a spring buckle is provided in the inner tube at the position corresponding to the second hole. The spring buckle includes a push-out end, and the upper part of the push-out end can pop out of the second hole of the inner tube. The snap fastener also includes a sleeve and an elastic element disposed within the sleeve; the lower part of the ejector end is connected to the elastic element, and the snap fastener slides within the sleeve when pressed under the elastic force provided by the elastic element.
2. The anti-stiction telescoping tube structure of claim 1, wherein, There are two second holes, and the line connecting the centers of the two second holes passes through the axis of the inner tube; there are also two ejector ends, which are connected by the elastic element and are both located inside the sleeve; and one ejector end pops out from one of the second holes.
3. The anti-stiction telescoping tube structure of claim 1, wherein, The sleeve is also provided with a limiting structure for limiting the downward pressing distance of the ejector end.
4. The anti-stiction telescoping tube structure of claim 1, wherein, The lower part of the ejector end has a stepped structure, and the outer diameter of the stepped structure is adapted to slide and connect with the inner diameter of the sleeve.
5. The anti-stiction telescoping tube structure of claim 4, wherein, The outer diameter of the stepped structure is larger than the diameter of the second hole.
6. The anti-stiction telescoping tube structure of claim 2, wherein, One of the ejector ends has a hollow lower portion configured as a sliding sleeve, and the other ejector end has a lower portion configured as a sliding rod slidably connected within the sliding sleeve; the elastic element is disposed between the sliding sleeve and the sliding rod.
7. The anti-stiction telescoping tube structure of claim 6, wherein, The slide bar is also equipped with a straightening block, which slides on the inner wall of the slide sleeve.
8. The anti-stiction telescoping tube structure of claim 7, wherein, The elastic element is a spring.
