Air distance measuring mechanism

The invention discloses an air distance measuring mechanism, and belongs to the field of measuring tools. The air distance measuring mechanism comprises a machine body which is internally provided with a processing unit and an engine. The processing unit and the engine are electrically connected. The machine body is provided with multiple connecting rods which are horizontally arranged. The tail end, which is away from the machine body, of each connecting rod is provided with a power unit which comprises a rotor wing. The rotor wing is connected with the engine in a transmission way. An instrument fixing device is arranged below the machine body. The instrument fixing device is provided with a laser distance measuring instrument which is electrically connected with the processing unit. The machine body is internally provided with a wireless signal transceiver which is electrically connected with the processing unit. An undercarriage is also arranged below the machine body. A measuring instrument is carried to the air by trees around high-voltage lines and other windage yaw points under the condition that ground measurement personnel cannot perform visual measurement, and a site in the air is selected to perform measurement work by the air distance measuring mechanism so that damage caused by cutting down vegetation and waste of the required manpower in ground measurement can be reduced.
