When the connecting sleeve rod 6 abuts against the first telescopic rod 2, the top and bottom of the connecting sleeve rod 6 and the first telescopic rod 2 can be in the same straight line, making the overall lines of the lamp appearance more simple and smooth, and further improving the aesthetics of the lamp. In addition, the inner diameter of the first telescopic rod 2 and the connecting sleeve rod 6 is matched with the outer diameter of the second telescopic rod 3, so that the second telescopic rod 3 can be clamped with the first telescopic rod 2 and the connecting sleeve rod 6, which is conducive to improving the structural stability of the lamp.

[0050] Embodiment 6:

[0051] As shown in Figure 1 On the basis of any of the above embodiments, the fixed rod 1 is vertically arranged, the first telescopic rod 2 extends away from the fixed rod 1, and the extension direction of the first telescopic rod 2 is perpendicular to the fixed rod 1.
