[0002] The application publication number of the related technology CN217864708U discloses a drone that is easy to shoot videos for geotechnical engineering surveys. The device uses a control mechanism and a support mechanism in coordination, and senses the horizontal state of the drone through a balance sensor. When the support plate contacts the rock and soil surface, the drone tilts, and the balance sensor transmits a signal to the control main board, and the control main board controls the electric telescopic rod to extend and retract, and adjusts through four electric telescopic rods until the balance sensor senses that the drone is in a horizontal state, and the electric telescopic rod stops adjusting, thereby enabling the shooting equipment on the drone to shoot high-quality videos, and later surveyors can accurately view the survey information.
