One side of the installation groove is opened with a moving groove 7. One end of the adjustment nut 5 penetrates through the moving groove 7 and is fixedly connected to the assembly rail 8;

[0026] In this embodiment, the user rotates the rotating rod 6. One end of the rotating rod 6 drives one of the adjustment screws 4 to rotate through a bevel gear and a direction-changing gear. The two adjustment screws 4 rotate synchronously under the action of the transmission sprocket and the transmission chain. Under the action of the thread, the adjustment nut 5 moves along the adjustment screw 4. The adjustment nut 5 drives the assembly rail 8 to move, so that the position of the LED lamp board 3 can be adjusted.

[0027] Embodiment 2. Please refer to Figure 4 and Figure 5 , an embodiment provided by the present utility model: an automotive headlight with a light curtain floating effect. An assembly strip 11 is movably inserted inside the assembly rail 8. A clamping structure is provided between the assembly strip 11 and the assembly rail 8. The clamping structure includes a convex block 12. The convex block 12 is fixedly installed on one side of the lower end of the assembly rail 8. A limit clamping block 14 is movably installed inside the convex block 12. The upper end of the limit clamping block 14 is movably inserted inside the assembly rail 8. A clamping spring 13 is fixedly installed at the lower end of the limit clamping block 14. One side of the upper end of the limit clamping block 14 is inclined. The other side of the upper end of the limit clamping block 14 is in contact with the assembly strip 11. An adjustment rod 15 is fixedly installed at the lower end of the limit clamping block 14. The lower end of the adjustment rod 15 is movably inserted outside the convex block 12;

[0028] In this embodiment, the user pulls down the adjusting rod 15. The adjusting rod 15 drives the limit clamping block 14 to move downward. The limit clamping block 14 compresses the clamping spring 13, causing the limit clamping block 14 to contract into the inside of the convex block 12. One end of the limit clamping block 14 is disengaged from one end of the assembly strip 11, enabling the assembly strip 11 to be withdrawn from the inside of the assembly rail 8, facilitating the quick disassembly of the LED light board 3.

[0029] Embodiment 3, please refer to Figure 6 and Figure 7 , an embodiment provided by the present utility model: an automotive headlight with a light curtain moving effect. One side of the assembly strip 11 is fixedly installed with a mounting strip 9. Both ends of one side of the mounting strip 9 are fixedly installed with mounting blocks 10. One side of the mounting block 10 is rotatably installed with a rotating block 19. An angle limiting structure is provided between the rotating block 19 and the mounting block 10. One end of the rotating block 19 is installed with an LED light board 3. The angle limiting structure includes a double-threaded sleeve 23. The double-threaded sleeve 23 is rotatably installed between the two mounting blocks 10. Anti-slip convex strips are uniformly arranged on the outer side of the double-threaded sleeve 23. Through holes are opened on both sides of the mounting block 10. A card slot 16 is opened on one side of the mounting block 10. A misaligned tooth ring 17 is arranged inside the card slot 16. A misaligned gear 18 that is engaged with the misaligned tooth ring 17 is movably inserted into the inside of the card slot 16. One end of the misaligned gear 18 is fixedly installed with a clamping screw 22. One end of the clamping screw 22 passes through the through hole and is inserted into the inside of the double-threaded sleeve 23. The clamping screw 22 is threadedly connected to the double-threaded sleeve 23;

[0030] In this embodiment, when the user rotates the double-threaded sleeve 23, under the action of the thread, the clamping screw 22 moves to both sides along the double-threaded sleeve 23. The clamping screw 22 drives the misaligned gear 18 to move, causing the misaligned gear 18 to move out of the card slot 16 and disengage from the misaligned tooth ring 17, enabling the rotating block 19 to rotate, facilitating the adjustment of the angle of the LED light board 3. After the adjustment, when the user rotates the double-threaded sleeve 23 in the reverse direction, under the action of the thread, the clamping screw 22 moves into the inside of the double-threaded sleeve 23, causing the misaligned gear 18 to contract into the inside of the card slot 16 and engage with the misaligned tooth ring 17, which can limit the angle of the LED light board 3.

[0031] Wherein, limiting blocks 21 are arranged on both sides of the inner wall of the through hole. Limiting grooves 20 are opened on both sides of the clamping screw 22. One end of the limiting block 21 is movably inserted into the inside of the limiting groove 20. The limiting block 21 can move in the limiting groove 20, preventing the clamping screw 22 from rotating and not following the double-threaded sleeve 23 to rotate, which would affect the movement of the clamping screw 22.
