[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 2 , Figure 3This utility model provides a technical solution: an LED power supply fixing device, including a box body 1, a box cover 2 at the top of the box body 1, and a fixing component inside the box body 1. The fixing component includes two placement slots 3, which are respectively opened on the front and rear surfaces inside the box body 1. A threaded rod 4 is rotatably connected to the inner side of the placement slot 3, and a clamping plate 5 is threaded between the two threaded rods 4. A first connecting rod 6 is rotatably connected to the rear end of one side of the box body 1, and a second connecting rod 7 is rotatably connected to the front end of one side of the box body 1. The ends of both the first connecting rod 6 and the second connecting rod 7 are fixedly connected to the ends of the threaded rods 4. A rotating rod 8 is rotatably connected to one side of the body 1. A rotating disk 14 is provided at the end of the rotating rod 8, and a first transmission roller 9 is fixedly connected to the surface of the rotating rod 8. A second transmission roller 10 adapted to the first transmission roller 9 is fixedly sleeved on the surface of the first connecting rod 6, and a third transmission roller 11 adapted to the first transmission roller 9 is fixedly sleeved on the surface of the second connecting rod 7. A first connecting belt 12 is provided between the third transmission roller 11 and the first transmission roller 9, and a second connecting belt 13 is provided between the second transmission roller 10 and the first transmission roller 9. A heat dissipation hole 15 is opened on the other side surface of the body 1, so that the device has good heat dissipation performance. The second transmission roller 10 and the third transmission roller 11 are connected to the first transmission roller 9. The moving rollers 11 are of the same size, so that when the first transmission roller 9 rotates, it can drive the first connecting rod 6 and the second connecting rod 7 to rotate synchronously. Existing LED power supplies come in various sizes, and when using a certain type of LED power supply fixing device, only that specific LED power supply can be fixed, limiting the use of the LED power supply fixing device and making it unsuitable for fixing LED power supplies of different sizes. In use, the LED power supply is placed in a suitable position inside the box 1, and then the operator rotates the rotating disk 14. The rotating disk 14 drives the rotating rod 8 to rotate. When the rotating rod 8 rotates, it drives the first transmission roller 9 and the second transmission roller 11 to rotate synchronously. 0. Under the action of the third transmission roller 11, the first connecting belt 12, and the second connecting belt 13, the first connecting rod 6 and the second connecting rod 7 are driven to rotate synchronously in the same direction. When the first connecting rod 6 and the second connecting rod 7 rotate, the placement groove 3 is driven to rotate. During the rotation of the placement groove 3, the two clamping plates 5 are driven to move closer to each other, thereby clamping and fixing the LED power supply, completing the operation. By designing the box body 1, the box cover 2, and the fixing components, the LED power supply device can clamp and fix different models of LED power supplies, effectively increasing the limitations of the LED power supply fixing device. The overall structure is compact and worth promoting and using.

[0019] In this embodiment, preferably, please refer to... Figure 1 , Figure 4As shown, it also includes a limiting assembly, which includes a fixing ring 16 located outside the rotating disk 14. A fixing rod 17 is provided on the top of one side of the fixing ring 16. A C-shaped frame 18 is provided on the front side of the fixing ring 16, and a through hole 19 is provided on the front surface of the fixing ring 16. A limiting rod 20 is provided inside the through hole 19. The limiting rod 20 is movably connected to the C-shaped frame 18, and a disc 21 is provided at the end of the limiting rod 20 near the C-shaped frame 18. A spring 22 is provided between the disc 21 and the C-shaped frame 18. The outer surface of the rotating disk 14 is open... A fixing groove 23 is provided to match the end of the limiting rod 20. The fixing ring 16, fixing rod 17, C-shaped frame 18, and limiting rod 20 are all made of plastic, saving material costs. By designing the limiting component, after the LED power supply is fixed inside the LED power supply fixing device, the operator can effectively limit and fix the rotating disk 14 by inserting the end of the limiting rod 20 into the fixing groove 23, so that the rotating disk 14 will not rotate arbitrarily, thus ensuring better stability after the LED power supply is fixed.
