Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Embodiment: please refer to Figures 1-5The light strip 10 is wound around the light strip 2 and is rotated by the rotating column 4. The light strip 10 is wound around the light strip 2 and is rotated by the rotating column 4. The light strip 10 is wound around the light strip 2 and is rotated by the rotating column 4. The light strip 10 is wound around the light strip 2 and is rotated by the rotating column 4. The light strip 10 is rotated by the rotating column 4. The light strip 10 is rotated by the rotating column 4. The light strip 10 is rotated by the rotating column 4. The light strip 10 is rotated by the rotating column 4

[0025] Furthermore, the groove 8 is communicated with the notch 6 , and the roller brush 10 in the groove 8 is in flexible extrusion contact with the light strip 3 .

[0026] Furthermore, the second notch 15 communicates with the inner cavity of the second groove 9 , and the chain 14 passes through the second notch 15 .

[0027] Furthermore, the limiting mechanism 16 includes a limiting post 161 disposed in the inner cavity of the winding shell 1 . The limiting post 161 is made of rubber and has a relatively rough end facing the winding reel 2 .

[0028] Furthermore, one end of the limiting post 161 is fixedly connected to a screw 162, which passes through the winding shell 1 and the two are threadedly connected. The end of the screw 162 away from the limiting post 161 is fixedly connected to the control disk 163. After the light strip 3 is wound into the winding shell 1, the control disk 163 can be used to drive the screw 162 to rotate, thereby driving the limiting post 161 to move and squeeze toward the winding disk 2. The pressure applied to the winding disk 2 is used to fix its position for easy storage. Conversely, the light strip 3 can be pulled out for use by loosening it, thereby improving the convenience of using this LED light strip with retractable function.

[0029] Furthermore, a U-shaped frame 18 is provided at the top of the inner cavity of the winding shell 1, and the U-shaped frame 18 is rotatably connected to the winding shell 1 by a second rotating shaft 19. A tightening roller 20 is provided for rotation inside the U-shaped frame 18, and a torsion spring 21 is provided between the second rotating shaft 19 and the winding shell 1.
