[0021] The utility model provides a technical solution: Figure 1-Figure 4As shown, in this embodiment, a retractable aluminum tube includes a first aluminum tube 1, the interior of the first aluminum tube 1 is slidably connected to a second aluminum tube 2, a positioning assembly is arranged between the first aluminum tube 1 and the second aluminum tube 2, the positioning assembly is used to limit the moving direction of the second aluminum tube 2, a receiving groove 14 is opened inside the first aluminum tube 1, the interior of the receiving groove 14 is rotatably connected to a rotating plate 9, a limiting assembly is arranged on one side of the rotating plate 9, the limiting assembly is used to fix the position of the second aluminum tube 2, and a card groove 5 is equidistantly opened on the top of the second aluminum tube 2.

[0022] First, when adjusting the length of the first aluminum tube 1, the limiting component is pressed to drive the rotating plate 9 to rotate, thereby releasing the limit on the second aluminum tube 2, and then pulling the second aluminum tube 2 can extend the length of the aluminum tube to adapt to different scene requirements, thereby avoiding the problem that the fixed-length aluminum tube cannot be extended or retracted, which may not meet the needs of different installation scenarios, resulting in installation difficulties or the need for additional processing, thereby increasing the practicality of the device. Next, when adjusting the length of the aluminum tube, the first aluminum tube 1 and the second aluminum tube 2 can be limited by the positioning component to avoid the problem of deviation of the second aluminum tube 2 during movement, thereby increasing the stability of the extension and retraction of the aluminum tube.

[0023] like Figure 1-Figure 4 As shown, the limit assembly includes a second spring 8, which is fixedly connected between the bottom of the rotating plate 9 and the inner wall of the containing groove 14. A limit groove 10 is provided on one side of the rotating plate 9. The limit assembly also includes a limit rod 13, which is slidably connected to the inside of the limit groove 10. A movable block 12 is rotatably connected to the outer side of the limit rod 13. A clamping block 15 is slidably connected to the inside of the first aluminum tube 1. One end of the clamping block 15 is fixedly connected to the bottom of the movable block 12. One end of the clamping block 15 extends through the first aluminum tube 1 to the inside of the clamping groove 5. A resisting rod 11 is slidably connected to the top of the first aluminum tube 1.
