[0025] The front and rear adjustment component 5 includes a front and rear adjustment telescopic rod 501 fixedly mounted on both ends of the outer side wall of the mounting back plate 1, one end of the front and rear adjustment telescopic rod 501 is connected to a front and rear adjustment plate 502, a limit rod 503 is fixedly mounted on the outer side wall of the front and rear adjustment plate 502, a limit hole is arranged on the mounting back plate 1, one end of the limit rod 503 is passed through the limit hole, a connecting block 504 is fixed on the outer side wall of the front and rear adjustment plate 502, and a linkage plate 505 is fixed on one end of the connecting block 504. When the front and rear adjustment telescopic rod 501 works, it can drive the front and rear adjustment plate 502 to be displaced, so that the front and rear adjustment plate 502 can drive the limit rod 503, the connecting block 504, the linkage plate 505 and other components to move, and finally the second LED arc box 7 can be moved forward or backward.
[0026] The left-right adjustment component 6 includes a left-right adjustment screw rod 601, and the bottom and top of the linkage plate 505 are both provided with strip grooves. The left-right adjustment screw rod 601 is rotatably installed in the strip groove. A driving motor 602 is fixedly installed on the outer wall of the linkage plate 505.
