[0013] The utility model provides an inspection UAV which is easy to maintain. Compared with the prior art, it has the following beneficial effects: when the UAV is flying normally, there are only mounting columns and threaded columns on the upper wall of the fuselage body, which ensures the lightness of the UAV. When the lower part of the UAV needs to be inspected and repaired, the UAV is placed on the inspection platform through the landing gear, and then the support column is installed on the threaded column until the support column fits on one end of the mounting column. The UAV is then inverted and placed on the inspection platform through an expansion block. An expansion block is provided at one end of the support column to increase stability, separate the fuselage body from the inspection platform, avoid sliding and wear between the fuselage body and the inspection platform, and also avoid collision between the propeller and the inspection platform, which facilitates the inspection of the UAV and ensures the quality of the UAV.
