[0037] The use process of the multi-dimensional adjustment mechanism of the street lamp cap provided by the present invention is as follows: The lamp head is shown as marked at A in the figure. When adjusting the lamp head, turn the first hand wheel 104, the first hand wheel 104 drives the first worm 101 to rotate, and during the rotation of the first worm 101, the support rod 204 and the support frame 201 are driven to rotate through the first worm wheel 102 and the first connecting shaft 103. Turn the second hand wheel 209, the second hand wheel 209 drives the second worm 208 to rotate, and when the second worm 208 rotates, it drives the second worm wheel 207 and the transmission shaft 206 to rotate, and the transmission shaft 206 drives the circular guide rail 203 to rotate through the second connecting shaft 202 connected thereto. After loosening the hand bolt 301, rotate the lamp head with the circular guide rail 203 as the center. In summary, the pitch, yaw and roll adjustments of the lamp head are achieved.
