[0030] Specifically, when installing the light bar body 3 and the LED backlight body 4 into the installation groove 2 of the substrate 1, the user drives the clamping column 8 to move in advance through the moving bar 12. At this time, the compression spring 10 and the telescopic rod 6 will perform corresponding contraction movements. When the clamping column 8 does not block the installation of the light bar body 3 and the LED backlight body 4, the light bar body 3 and the LED backlight body 4 are then placed into the installation groove 2 of the substrate 1. Then, the moving bar 12 is released. At this time, the compression spring 10 loses its restriction and drives the telescopic rod 6 to perform a stretching movement under the action of its own elastic force. The telescopic rod 6 then drives the clamping column 8 to be clamped into the clamping hole 9, so that the light bar body 3 and the LED backlight body 4 can be fixed, and the installation and fixing work of the light bar body 3 and the LED backlight body 4 and the substrate 1 is completed.

In summary, the utility model is relatively simple and convenient when disassembling the light bar body 3, the LED backlight body 4, and the substrate 1, and does not require the aid of any tools, thereby improving the overall assembly efficiency.

[0032] Example 2

Therefore, the utility model facilitates the installation and disassembly of the two substrates 1, and the assembly is more convenient.

[0037] Secondly, when installing the light bar body 3 and the LED backlight body 4 into the installation groove 2 of the substrate 1, the user drives the clamping column 8 to move in advance through the moving bar 12. At this time, the compression spring 10 and the telescopic rod 6 will perform corresponding contraction movements. When the clamping column 8 does not block the light bar body 3 and the LED backlight body 4 from being installed, the light bar body 3 and the LED backlight body 4 are then placed into the installation groove 2 of the substrate 1, and then the moving bar 12 is released. At this time, the compression spring 10 loses its restriction and drives the telescopic rod 6 to perform a stretching movement under the action of its own elastic force. The telescopic rod 6 then drives the clamping column 8 to be clamped into the clamping hole 9, and the light bar body 3 and the LED backlight body 4 can be fixed, completing the installation and fixing work of the light bar body 3 and the LED backlight body 4 and the substrate 1;

[0038] Finally, when disassembling the light bar body 3, the LED backlight body 4, and the substrate 1, the user drives the clamping column 8 to move through the moving bar 12 in advance. At this time, the compression spring 10 and the telescopic rod 6 will perform a corresponding contraction movement. After the clamping column 8 is disengaged from the clamping hole 9, the light bar body 3, the LED backlight body 4, and the substrate 1 can be disassembled. In summary, the utility model is relatively simple and convenient when disassembling the light bar body 3, the LED backlight body 4, and the substrate 1, and does not require the aid of any tools, thereby improving the overall assembly efficiency.
