[0023] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0024] Please refer to Figures 1-4 , the present utility model discloses a telescopic sleeve, including a sleeve assembly 1. The sleeve assembly 1 includes a movable outer tube 11, a movable inner tube 12, and a fixed tube 13. The movable inner tube 12 is movably sleeved inside the movable outer tube 11. The fixed tube 13 is fixedly arranged at one end of the movable inner tube 12 away from the movable outer tube 11. A spring buckle 15 that is clamped with the movable outer tube 11 is arranged on the movable inner tube 12. The fixed tube 13 does not need to be prepared separately and can be made by cutting the movable outer tube 11, further reducing the manufacturing difficulty.

[0025] Specifically, the inner diameter and outer diameter of the fixed tube 13 and the movable outer tube 11 are the same. On both sides of one end of the movable outer tube 11 away from the movable inner tube 12, fixing buckles one 16 are symmetrically arranged. On both sides of one end of the fixed tube 13 away from the movable inner tube 12, fixing buckles two 18 are symmetrically arranged. Refer to Figure 4, during use, since the inner and outer diameters of the fixed tube 13 and the movable outer tube 11 are the same, the docking structure dimensions at both ends of the sleeve assembly 1 are the same, effectively reducing the assembly difficulty and manufacturing process, with high versatility. The settings of the first fixing buckle 16 and the second fixing buckle 18 facilitate the insertion into the interior of the docking part during later docking, improving stability. The sleeve assembly 1 can be applied to common telescopic products on the market, such as folding golf bags, folding backpacks, folding chairs, etc.

[0026] Specifically, a clamping hole 14 matching the spring buckle 15 is formed on the movable outer tube 11. During the shortening process, by pressing the spring buckle 15 to compress the spring piece 17 and storing it inside the movable inner tube 12, the movable inner tube 12 can be slid to move inside the movable outer tube 11. During this process, the end of the spring buckle 15 continuously abuts against the inner wall of the movable outer tube 11. When elongating, the movable inner tube 12 and the movable outer tube 11 are pulled away from each other. When the spring buckle 15 moves to be opposite to the clamping hole 14, the spring buckle 15 without obstruction is elastically abutted by the spring piece 17 and snaps into the interior of the clamping hole 14, completing the positioning of the movable inner tube 12 and the movable outer tube 11 and preventing further relative movement.

[0027] Specifically, one end of the spring buckle 15 extends into the movable inner tube 12 and two spring pieces 17 are symmetrically arranged. Refer to Figure 3 , the spring piece 17 is arranged in a V shape. This design method makes the pressing process of the spring buckle 15 more stable and the operation more flexible.

[0028] In summary, compared with common telescopic sleeves on the market, the setting of the fixed tube 13 in this telescopic sleeve makes the structures at both ends of the sleeve assembly 1 the same, which is more convenient for later docking products, effectively reducing the assembly difficulty and manufacturing process, with high versatility and low manufacturing difficulty. The fixed tube 13 does not need to be manufactured separately and can be made by cutting the movable outer tube 11, further reducing the manufacturing difficulty, meeting economic benefits, and having a broad application prospect.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
