VEHICULAR HEADLAMP ADJUSTMENT DEVICE

A vehicular headlamp adjustment device is provided which comprises a housing, and a motor assembly, a dual gear, a gear disk and an inner sleeve tube; a ball head ejector rod is helically assembled in the inner sleeve tube, and the motor assembly runs through a dual gear to drive the gear disk to rotate; the housing further comprises an outer sleeve tube. One end of the outer sleeve tube is rotatably connected to the housing, and the other end clamped and matched with the ball head ejector rod. When manually rotating the outer sleeve tube, the ball head ejector rod rotates with it; due to spiral fit between the ball head ejector rod and the inner sleeve tube, and the relative sliding between the outer sleeve tube and the ball head ejector rod, the ball head ejector rod expands and contracts axially under the action of the spiral structure.
