Screwed into the upper sleeve of the upper sleeve, the upper part of the sleeve is connected with the small tube, and the lower part of the lower sleeve is connected by the big: large: the upper sleeve and the lower sleeve are screwed and pressed together, and then the small tube is connected ^ The point is that the upper sleeve and the lower sleeve must be screwed together with the old tight (four) phase to be able to tighten the small tube and the large tube. [New content] ^Resolve the lack of the above-mentioned habits, the added value of domain customization. 'This creator started research and developed this creation, and the purpose of this creation is to provide a fixed joint structure (1) of telescopic tube. Force the small tube and the big tube. The construction county of the present invention comprises an upper sleeve and a lower sleeve, wherein the upper sleeve of the basin is provided with a thread on the inner side of the upper sleeve, and the upper sleeve is provided with a longitudinal groove connected to the upper end, and the outer side of the lower sleeve is provided. The thread is screwed into the upper sleeve correspondingly, and the inner ring of the upper sleeve is provided with a rib. 5 M290195 wherein the ridge has at least one or more strips. m, disposed on the upper sleeve The inner side of the groove is provided. The ring is correspondingly fitted, and the small tube is provided with the groove. Therefore, the following advantages are obtained: 2. The friction between the inner side of the sleeve and the small tube is added; the convex strip of the lower sleeve Increase the friction between the tube and the small tube. 3· f Use light force to tighten the small tube and the large tube; the upper sleeve and the lower sleeve are relatively tight and the number of turns is small, so the spinning force is small. The service life of the cylinder and the lower sleeve; due to the small number of relatively tight turns, the smaller the spinning force, the upper sleeve and the lower sleeve can be more durable. [Embodiment] First, see the first and second figures. Show that this creation example includes a t sleeve (1) and a lower sleeve (2), and cooperates with the small tube (3) and large (4) implemented, wherein the inner sleeve (1) is provided with a thread (11) inside, and the upper sleeve (2) is provided with a longitudinal section and a groove (21) connected to the upper end, and the outer side of the lower sleeve (2) Threading (22) is provided to correspondingly thread (11) screwed into the upper sleeve (1), characterized in that: the inner ring of the upper section of the lower sleeve (2) is provided with a rib (23). The rib (23) is disposed on the inner side of the lower sleeve (2) at the groove (21). By the same as the second figure, the upper sleeve of the upper sleeve (1) is connected to the small tube M290195 (3), =' and the outer wall of the small tube (3) corresponds to the rib (23) of the lower sleeve (7), by which the friction of the lower sleeve (2) against the small tube (3) is increased, and the lower sleeve The inner and lower sections of the cylinder (2) are connected to the large tube (4).
