By pushing the first connector 36 to slide up or down on the outside of the vertical rod 3 and then locking it, one of the cross bars 2 can be adjusted to rise or fall, thereby adjusting the smoothness of the curtain 1 after the surface is tightened.

[0045] Please refer to Figure 1 、 Figure 7 and Figure 8 .

[0046] The other end of the vertical rod 3 is detachably connected to the support assembly 4. The other end of the vertical rod 3 is provided with a second elastic piece 34. The second elastic piece 34 is located in the second tube 31. One end of the second elastic piece 34 extends to have a second protrusion 341. The second protrusion 341 passes through the second tube 31.

[0047] The support assembly 4 includes a connector 41 and two fifth tubes 42. The top of the connector 41 is provided with a hole, and the inner wall of the hole is provided with a second through hole. The other end of the vertical rod 3 is inserted into the hole, and the other end of the second elastic piece 34 contacts the inner wall of the second tube 31. The second elastic piece 34 uses its own rebound to push the second protrusion 341 into the second through hole.

[0048] Through slots are provided on both sides of the connector 41, and first and second slots 411 and 412 are provided on the edges of both sides of the through slot, and the second slot 412 is located above the first slot 411; a central axis 421 is provided at one end of the fifth tube 42, and the central axis 421 passes through the fifth tube 42, and the two ends of the central axis 421 are respectively rotatably connected to the two sides of the inner wall of the through slot; two sliding slots 422 are provided on the outer side of the fifth tube 42, and the sliding slot 422 passes into the fifth tube 42, and a sliding rod 423 is provided in the fifth tube 42, and the sliding rod 423 is placed in the two sliding slots 422, and the two ends of the sliding rod 423 respectively pass through the fifth tube 42 from the two sliding slots 422, and a tension spring 424 is provided in the fifth tube 42, and the two ends of the tension spring 424 are respectively fixedly connected to the central axis 421 and the sliding rod 423;

[0049] When the fifth tube 42 is rotated 90° on the connector 41 so that the fifth tube 42 and the vertical rod 3 are perpendicular to each other, the fifth tube 42 pulls the sliding rod 423 toward the first clamping groove 411. The tension spring 424 pulls the sliding rod 423 to slide in the sliding groove 422 and clamp into the first clamping groove 411. The two fifth tubes 42 touch the ground, and the fifth tube 42 can improve the balance of the connector 41 supporting the vertical rod 3.

[0050] When the fifth tube 42 rotates -90° on the connector 41, so that the fifth tube 42 and the vertical rod 3 are parallel to each other, the fifth tube 42 pulls the slide bar 423 close to the second slot 412, and the tension spring 424 pulls the slide bar 423 to slide in the slide bar 422 and snap into the second slot 412, thereby retracting the two fifth tubes 42 and reducing the size of the support assembly 4 for easy storage.

[0051] Please refer to Figures 1-8 .

[0052] When folding the curtain 1 and the bracket:

[0053] The first protrusion 241 is pushed to compress the first elastic piece 24, allowing the first protrusion 241 to disengage from the first through hole 362, thereby releasing the first protrusion 241 from the position restraining one of the cross bars 2. This allows the two ends of one of the cross bars 2 to be detached from the two first connectors 36 respectively, and the other cross bar 2 to be removed from the second connector 37. The cross bar 2 is then pulled out of the connecting ring 11 on the curtain 1. The first tubes 21 and the third tubes 25 are sequentially disconnected from each other, and the first tubes 21 and the third tubes 25 are folded in a serpentine shape, thereby shortening the length of the cross bar 2.
