The bonfires lit by ancient ancestors are the earliest lights. The development of modern human civilization is always inseparable from flame and light. Street lights are also guiding the birth and glory of human civilization. In order to overcome the fear and anxiety brought by darkness to human beings , so that street lamps are built in the city to bring light. The current street lamps adopt a fixed design, and the area of ​​illumination is relatively single and fixed, which cannot illuminate every corner of the city.

[0003] Chinese patent (notification number: CN209146927U) discloses a liftable double-headed landscape street lamp, a mounting base, a light pole, a guide sleeve and a lifting assembly; the light pole is set on the mounting base; the lifting assembly is set on the In the light pole; the lifting assembly includes an electric screw and a vertical support; the electric screw is located inside the mounting seat, and the screw of the electric screw extends to the upper end of the light pole; the vertical support is connected to the electric screw It is suitable for following the electric screw to drive the guide sleeve to move up and down along the light pole. Although the device can adjust the height of the street lamp to a certain extent, due to the differentiated lighting of the street lamp, the lighting height at both ends is usually required. Obviously, the above-mentioned street lamps cannot meet these requirements. At the same time, the lifting of the device is to adjust the entire lamp post, and the safety factor is also low. Therefore, further improvement is still needed.
