[0004] When the device is in use, the pressure ring is squeezed by the spring, so that the pressure ring presses the LED light strip body downward, thereby limiting and fixing the LED light strip body. However, the spring has a certain deformation capacity, and it will deform during long-term use, which will cause its elastic force to weaken, and it is impossible to stably press the LED light strip body through the pressure ring, resulting in the LED light strip body being pulled by external force and rotating and stretching at will.

[0010] As a preferred technical solution of the utility model, two baffles are symmetrically fixedly arranged on the bottom wall of the installation frame, and a screw rod is threaded through the surface of the two baffles. One end of the two screw rods is connected with a clamp for limited rotation, and the top wall of the clamp is connected to the bottom wall of the installation frame for limited sliding.

[0011] As a preferred technical solution of the utility model, rubber pads are connected to the opposite surfaces of the two clamping plates.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] The limited rotation connection of the worm is realized by the coordinated setting of the rotating rod and the fixed seat, and the limited rotation connection of the guide roller is realized by the meshing connection of the worm and the worm wheel set by the limited rotation.
