Anti-collision undercarriage structure of unmanned aerial vehicle

The utility model relates to the technical field of unmanned aerial vehicle undercarriages, in particular to an anti-collision undercarriage structure of an unmanned aerial vehicle. Comprising a mounting plate and an extension rod, a buffer box is mounted below the mounting plate, a hydraulic damper is mounted in the buffer box, the outer side of the hydraulic damper is sleeved with a high-strength spring, an auxiliary spring is mounted in the buffer box, a guide rod is connected to the upper portion of the hydraulic damper, and buffer supporting legs are fixedly mounted below the buffer box; the extension rod is installed on the outer side of the buffer box, and the lower portion of the extension rod is connected with an anti-inclination supporting foot. And when the unmanned aerial vehicle descends, the buffer supporting feet and the anti-inclination supporting feet make contact with the ground, the guide rods retract into the buffer boxes, the guide rods extrude hydraulic dampers, high-strength springs and
