Hinges are welded at both ends of the connecting rod 317, and one end of the two hinges is welded to the movable plate 316 and the connecting rod 318 respectively. Through the light source board 300, the installation slot 311, the card slot 312, the card seat 313, the matching movable slot 314, the matching support column 315, the movable plate 316, the connecting rod 317, the connecting rod 318, the compression spring 319, the brake slot 321 and the brake hole 322 In cooperation, first move the card seat 313 downward in the installation groove 311. When the card seat 313 moves to the bottom of the installation groove 311, the card column 326 can be driven to move under the action of the compression spring 319, so that the card column 326 enters the card groove 312. Through the cooperation of the locking plate 323, the tension spring 324, the brake column 325, the card column 326, the moving hole 327, the installation through hole 328, the light source 330 and the slide plate 340, after the card column 326 moves to the card groove 312, the locking plate 323 is pushed to move the brake column 325 to the limit. The latch 326 is clamped in the groove, and the sliding plate 340 is finally moved to the top of the braking groove 321, so that the sliding plate 340 limits the locking plate 11. The present invention is easy to operate. First, the clamping seat 313 is moved to the bottom of the installation groove 311, so that the clamping column 326 moves into the braking clamping groove 2, and then the locking plate 323 is pushed to make the braking column 325 move into the limiting groove, and finally the sliding plate 340 is moved to limit the locking plate 323. The light source 330 can be clamped on the light source board, and it is easy to disassemble, which is convenient when replacing the light source 330.

[0053] Working principle: When the light source 330 needs to be installed on the light source board, the moving plate 316 is first moved upward to drive the connecting rod 317 to rotate. When the connecting rod 317 rotates, the two connecting rods 318 can be brought closer to each other, and then the two clamping columns 326 can be brought closer to each other. Then the clamping seat 313 is moved downward in the installation groove 311. When the clamping seat 313 moves to the bottom of the installation groove 311, the clamping column 326 can be driven to move under the action of the compression spring 319, so that The clamping column 326 enters the clamping slot 312. After the clamping column 326 moves to the clamping slot 312, the locking plate 323 is pushed, so that the locking plate 323 drives the brake column 325 to move, and the brake column 325 is moved to the limiting groove, and the clamping column 326 is clamped. Finally, the slide plate 340 is moved to the top of the brake groove 321, so that the slide plate 340 limits the locking plate 11, and the light source 330 can be clamped on the light source board, and it is easy to disassemble, which has a certain convenience when replacing the light source 330.
