The adjusting unit A is connected with the low beam bracket 1 by means of a ball socket I8 arranged in a ball socket hole 31 of the low beam bracket 1.

As shown in fig. 4 and 5, the linkage rod mounting area B is mainly mounted through a linkage rod 9, a first metal sheet 10 and a second metal sheet 11. A ball head structure II 20 of the high beam support 2 is installed in a columnar blind hole I17 of the linkage rod 9, and a ball head structure I19 of the low beam support 1 is installed in a columnar blind hole I18 of the linkage rod 9; the first metal sheet 10 and the second metal sheet 11 are symmetrically arranged below the linkage rod 9, as shown in fig. 6, 7 and 8, a first limit post through hole 22 of the first metal sheet 10 and a first limit post through hole 25 of the second metal sheet 11 are overlapped with a circular through hole 16 of the linkage rod 9, a first elastic clamping structure 23 of the first metal sheet 10 is clamped at the front end of a first columnar blind hole 17 of the linkage rod 9, and a second elastic clamping structure 26 of the second metal sheet 11 is clamped at the front end of a second columnar blind hole 18 of the linkage rod 9; spacing post 27 of car light casing passes spacing post through-hole 22, spacing post through-hole 25 and the circular through-hole 16 of coincidence, and is right the gangbar installation region B carries on spacingly, elasticity card structure 23 with elasticity card structure two 26 can produce elastic deformation, both realize that gangbar 9 uses the spacing post of car light casing 27 as the rotary motion of axle center, realize again passing through optical bracket 1 drive passing through optical module with it is spacing that distance optical bracket 2 drives the rotation when distance optical module carries out synchronous level adjustment for the synchronous rotation of the spacing post 27 of car light casing, has guaranteed that the rotation angle of gangbar 9 is unlikely to too big, has avoided among the horizontal adjustment process because excessive adjustment leads to adjusting the defect of inefficacy.
