Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model provides a technical scheme, referring to fig. 1, 2 and 3, the telescopic aluminum pipe comprises an inner pipe 1 and an outer pipe 2, wherein a limit chute 101 is formed on the outer wall of the inner pipe 1, a tooth slot 102 is formed on the inner side of the limit chute 101, a limit clamping strip 202 is mounted on the inner wall of the outer pipe 2, a movable groove 203 is formed on the outer pipe 2, an elastic plate 204 is mounted in the movable groove 203, the elastic plate 204 is made of an elastic steel material, teeth 205 are mounted at the upper end part of the elastic plate 204, and a thread sleeve 3 is sleeved on the outer pipe 2;

referring to fig. 2, 3 and 4, the limiting clamping strip 202 of the outer tube 2 is slidably clamped with the limiting sliding groove 101 of the inner tube 1, so that the outer tube 2 and the inner tube 1 do not axially move when being extended or retracted, the position of the movable groove 203 corresponds to the tooth groove 102, the tooth 205 is engaged with the tooth groove 102, the threaded sleeve 3 is rotated to move up the threaded sleeve 3 to press the elastic plate 204, and after the elastic plate 204 is pressed, the tooth 205 is engaged with the tooth groove 102 in the limiting sliding groove 101, so that the length is adjusted to be limited.
