[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The curtain telescopic rod comprises a main telescopic rod 1, wherein the main telescopic rod 1 comprises a first rod 101 and a second rod 102 having one end inserted into the first rod 101, wherein the second rod 102 is provided with a rotating telescopic mechanism which makes the second rod 102 have a tendency to reset when the second rod 102 moves axially along the first rod 101; the rotating telescopic mechanism has been disclosed in the patent with publication number CN218074446U and will not be described in detail here.

[0023] The curtain telescopic rod also includes an external rod 103 and an end seat 104 . The external rod 103 is detachably connected to the end of the main telescopic rod 1 , and the end seat 104 is detachably connected to both ends of the extension rod composed of the main telescopic rod 1 and the external rod 103 .

[0024] Specifically, the first rod 101 , the second rod 102 and the external rod 103 are all round tubes, and the external rod 103 is threadedly connected to the main telescopic rod 1 .

[0025] When the inner diameter of the external rod 103 is larger than the outer diameter of the first rod 101 or the second rod 102 , the end of the first rod 101 or the second rod 102 corresponding to the external rod 103 is provided with an external thread, and the end of the external rod 103 is provided with a corresponding internal thread.

[0026] When the inner diameter of the external rod 103 is smaller than the outer diameter of the first rod 101 or the second rod 102, the end of the first rod 101 or the second rod 102 corresponding to the external rod 103 is provided with an internal thread 105, and the end of the external rod 103 is provided with an external thread 106 corresponding thereto; this embodiment adopts this method, and the external rod 103 is threadedly connected to the second rod 102.

[0027] In some embodiments, a plurality of external connecting rods 103 are provided, and the additional external connecting rods 103 are threadedly connected to adjacent external connecting rods 103 or the main telescopic rod 1 to meet the requirements of more lengths.

[0028] Specifically, the length of each external rod 103 does not exceed 0.5 m, and the maximum length of the main telescopic rod 1 does not exceed 1.2 m. This design facilitates the transportation of the main telescopic rod 1 and the external rod 103.

[0029] In this embodiment, the end seat 104 is threadedly connected or sleeved on the end of the extension rod. Specifically, one end seat 104 is threadedly connected to the first rod 101 , and the other end seat 104 is threadedly connected to the external rod 103 .
