[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1-4, an LED flexible circuit board, including a first plate body 1, a second plate body 2 is placed on one side of the first plate body 1, and the outer sides of the second plate body 2 and the first plate body 1 are both sleeved with a sleeve frame 3, the inner side of the sleeve frame 3 is provided with a through hole 7, and an LED lamp 4 is placed above the sleeve frame 3, the surface of the first plate body 1 and the second plate body 2 are both provided with a second access groove 8, and the second access groove 8 and the pin portion of the LED lamp 4 are plugged in, the inner side of the sleeve frame 3 is movably connected to an abutment rod 9, and the outer wall of the abutment rod 9 A slider 10 is connected, and the slider 10 and the sleeve frame 3 are slidably connected. The abutment rod 9 is an arc-shaped structure, and the abutment rod 9 is symmetrical about the horizontal axis of the sleeve frame 3. After the pin portion of the bottom end of the LED lamp 4 is inserted into the second access groove 8, the fixing operation is completed by soldering technology, and the formed tin valley pile structure can support the abutment rod 9, so that it moves along the sleeve frame 3 through the slider 10. Therefore, the other end of the abutment rod 9 abuts on the plate body, thereby simultaneously completing the stabilization work between the sleeve frame 3 and the plate body;

[0023] One end of the first board 1 and the second board 2 are both connected to a pin 5, and the other end of the first board 1 is provided with a first access groove 6. The pin 5 is electrically connected to the metal guide sheet on the inner wall of the first access groove 6. The pin 5 at the end of the second board 2 is inserted into the first access groove 6 at one end of the first board 1, so that the pin 5 serves as a conductive medium, so that the circuit board as a whole forms a path, which is convenient for the LED lamp 4 to perform lighting work. The first board 1 and the second board 2 both include a metal foil layer 12, and a covering layer 11 is provided at the top and bottom of the metal foil layer 12. The metal foil layer 12 and the pin 5 are welded, and the pin 5 and the metal foil layer 12 play a conductive role, which is better for the LED lamp 4 installed on the board to perform conductive work. The metal foil layer 12 is made of copper. The second access groove 8 is opened on the metal foil layer 12, which is convenient for electrical connection with the pin part at the bottom of the LED lamp 4.

[0024] Working principle: When in use, the staff first splices multiple groups of horizontally placed first plates 1 and second plates 2 in sequence, with the second plate 2 as the initial end. Then, the sleeve frame 3 is sleeved along the outside of the plate body, and moved around the second access slot 8, so that the through hole 7 and the second access slot 8 form a surround. People then plug the pins at the bottom of the LED lamp 4 into the second access slot 8, and use soldering technology to complete the fixing operation. The tin valley pile structure formed can support the abutment rod 9, so that it moves along the sleeve frame 3 through the slider 10, so the other end of the abutment rod 9 abuts on the plate body, thereby synchronously completing the stabilization work between the sleeve frame 3 and the plate body. Finally, by powering the pin 5 at the tail end of the first plate body 1, the circuit board completes the path work of the LED lamp 4, which facilitates the LED lamp 4 to perform lighting work.
