The pulling block 210 is pulled in a direction away from the LED backlight source body 1, and the pulling block 210 is driven by the pulling force to drive the pressing plate 209 to move. When the pressing plate 209 moves, the first spring 207 and the telescopic rod 208 shrink. After the pressing plate 209 is completely away from the LED backlight source body 1, the movable frame 205 can be moved. After the movable frame 205 is moved to completely not block the LED backlight source body 1, the LED backlight source body 1 can be separated from the installation front frame 201. The interior of the installation front frame 201 is fixedly connected with a fixing rod 211, and the arc surface of the fixing rod 211 is fixedly connected with a first limit block 214. The fixing rod 211 and the first limit block 214 are fixed. The arc surface of the fixing rod 211 is rotatably connected with a first abutment plate 215, and one side of the first abutment plate 215 is slidably connected with the LED backlight source body 1. The effect of the first abutment plate 215 rotating on the fixing rod 211 is achieved. One end of the first abutment plate 215 is fixedly connected with a protrusion 216, and the outside of the protrusion 216 is slidably connected with a recess 217. The effect of matching the protrusion 216 and the recess 217 is achieved. One end of the recess 217 is fixedly connected with a second abutment plate 218, and one side of the second abutment plate 218 is slidably connected to the LED backlight source body 1. The effect of the second abutment plate 218 moving to drive the recess 217 to move is achieved. One end of the second abutment plate 218 is rotatably connected to the support rod 213, one end of the support rod 213 is fixedly connected to the front mounting frame 201, and the arc surface of the support rod 213 is fixedly connected with the second limit block 212. The effect of the second abutment plate 218 rotating on the support rod 213 and the second limit block 212 preventing the second abutment plate 218 from detaching from the support rod 213 is achieved.

[0034] Reference Figure 4 As shown, in this embodiment: the support device 3 includes two support plates 31, one side of the two support plates 31 is fixedly connected to the LED backlight source body 1, one side of the support plate 31 is fixedly connected to a retractable rod 32, and one end of the retractable rod 32 is fixedly connected to a force-bearing plate 34.

The retractable rod 32 prevents the second spring 33 from deforming during the stretching or contraction process. One side of the rubber frame 36 is slidably connected to an anti-skid frame 35, and one side of the anti-skid frame 35 is fixedly connected to the force-bearing plate 34. The anti-skid frame 35 increases the friction force.

[0035] Working principle: through the fixing device 2, when the LED backlight source needs to be installed, the operator first places the LED backlight source body 1 in the installation front frame 201, and pulls the pull block 210 in the direction away from the installation front frame 201. The pull block 210 is subjected to the pulling force to drive the pressure plate 209 to move. When the pressure plate 209 moves, the first spring 207 and the telescopic rod 208 are in a contracted state. After the pressure plate 209 is completely away from the installation front frame 201, it moves the moving frame 205. After the moving frame 205 moves to the maximum limit in the direction of approaching each other, the pull block 210 is released. At this time, the first spring 207 rebounds and drives the pressure plate 209 to fix the LED backlight source body 1 placed in the installation front frame 201. The fixing device 2 solves the problem that the traditional LED backlight source installation structure basically uses a number of fixing bolts to install and fix the LED backlight source, which is cumbersome to install and disassemble, and it is inconvenient to disassemble and repair the LED backlight source when it is damaged.

[0036] By means of the support device 3, when it is necessary to increase the buffering effect of the LED backlight source, the operator first fixes the support plate 31 and the LED backlight source body 1, the support plate 31 is fixed to the second spring 33 and the retractable rod 32, the second spring 33 and the retractable rod 32 are fixed to the force-bearing plate 34, when the LED backlight source body 1 is about to be squeezed, the force-bearing plate 34 is squeezed first, causing the second spring 33 to shrink to form a certain buffer, and by means of the support device 3, the problem of the traditional LED backlight source installation structure having no buffering effect and low safety of the LED backlight source is solved.
