[0023] Specifically, the protective shell 1 is provided with heat dissipation holes 101 which penetrate the front and rear surfaces of the protective shell 1 to ensure air circulation in the protective shell 1 so that the LED driving power supply can effectively dissipate heat when working. The inner cavity of the protective shell 1 is hollow, and a slide groove 102 is provided on the front and rear surfaces of the inner cavity of the protective shell 1. A plurality of evenly distributed springs 2 are fixedly welded in the slide groove 102, and a fixing plate 3 is fixedly welded at the other end of the spring 2, and the fixing plate 3 is located in the slide groove 102, so that when an object squeezes the fixing plate 3, the fixing plate 3 will move into the slide groove 102, and the spring 2 will apply elastic potential energy to the fixing plate 3, thereby achieving the effect of fixing the object. A top cover 4 is slidably connected to the top of the protective shell 1, and a slider on the side of the top cover 4 is slidably connected in the slide groove 102, and the shape of the top cover 4 is consistent with the top of the protective shell 1, so that when the top cover 4 slides to the side of the protective shell 1, it can just cover the top of the protective shell 1, thereby achieving the effect of protecting the driving power supply, and a fixing plate 3 is fixed on the side of the top cover 4. A limit rod 5 is welded, and the limit rod 5 is movably connected in the limit groove 103 on the side of the protective shell 1, and a groove is opened on the upper surface of the limit rod 5, in which a spring 2 is arranged, and a contraction damper 6 is arranged in the spring 2, and a button 7 is fixedly welded on the top of the contraction damper 6, so that the button 7 can be pressed into the groove, so that the limit rod 5 slides in the limit groove 103, and the button 7 can extend the service life of the spring 2 and the button 7.

[0024] The working principle and use process of the utility model are as follows: first, the driving power supply is installed at the bottom of the inner cavity of the protective shell 1, and then the top cover 4 is pushed in along the slide groove 102, and the top cover 4 will squeeze the fixing plate 3, thereby squeezing the spring 2, and the spring 2 will feed back an elastic potential energy to the fixing plate 3, thereby achieving the effect of clamping and fixing the top cover 4. When it is pushed to a certain extent, the user can press the button 7 by hand, and then the limit rod 5 will provide a limit groove 103. When the top cover 4 completely covers the top of the protective shell 1, the button 7 will slide out of the limit groove 103, and then be ejected by the spring 2 in the limit rod 5, blocking the limit rod 5 from returning to the inside of the protective shell 1, and finally fixing the top cover 4 on the top of the protective shell 1, thereby achieving the effect of protecting the driving power supply. When the driving power supply fails, press the button 7 and pull the top cover 4 to pull out the top cover 4, and then the driving power supply can be repaired.
