This invention relates to a street light pole for quick replacement of street light heads, belonging to the field of lighting equipment technology. It includes a lower section of the light pole vertically supported on the ground, an upper section of the light pole rotatably connected to the top of the lower section, and a mounting bracket for installing the street light head, located at the top of the upper section. The top of the lower section is rotatably connected to the middle of the upper section. A steel wire rope is provided at the bottom side of the upper section, and a fixed pulley is rotatably provided at the bottom side of the lower section. The steel wire rope is wound around the fixed pulley. Slowly rotating the fixed pulley releases the steel wire rope and causes the upper section to rotate from a vertical to an inclined position. Its advantages are that it makes street light head replacement faster, more convenient, and safer.
