Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 to 3, the telescopic rod provided by the present invention comprises an inner tube 1, an outer tube 2 and a limiting member 3, wherein the inner part of the outer tube 2 is hollow, an installation groove 21 is provided on the inner wall of the outer tube 2, an elastic mechanism 22 is fixed in the installation groove 21, and the elastic mechanism 22 is fixedly connected with a marble 23; the inner pipe 1 is inserted into the outer pipe 2, a plurality of limiting grooves 11 distributed along the height direction of the inner pipe 1 are formed in the outer wall of one end of the inner pipe 1, the size of each limiting groove 11 is matched with that of each marble 23, the vertical distance between every two adjacent limiting grooves 11 is equal, and a limiting hole 12 is formed in the outer wall of the other end of the inner pipe 1 at a position corresponding to each limiting groove 11; the locating part 3 is sleeved on the lower portion of the outer pipe 2, the locating part 3 comprises a first fixed arc-shaped ring 31, a second fixed arc-shaped ring 32 and a shifting bar 33, one end of the shifting bar 33 is provided with a notch 36, the other end of the shifting bar 33 is provided with a limiting column 35 matched with the limiting hole 12, the limiting column 35 is fixed on the shifting bar 33 through welding, one end of the first fixed arc-shaped ring 31 is fixedly connected with one end of the second fixed arc-shaped ring 32 through welding, the other end of the first fixed arc-shaped ring 31 and the other end of the second fixed arc-shaped ring 32 are accommodated in the notch 36 of the shifting bar 33, the first fixed arc-shaped ring 31 and the shifting bar 33 are rotatably connected through a pin shaft 34, the second fixed arc-shaped ring 32 and the shifting bar 33 are rotatably connected through a pin shaft 34, the first fixed arc-shaped ring 31 is fixed on the outer wall of the outer pipe 2 through screws, and.
