Description

technical field [0001] The invention relates to the technical field of aircraft maintenance, in particular to an aircraft flap handle device. Background technique [0002] After investigation, in order to ensure that the aircraft can fly normally, it is necessary to carry out regular maintenance on the aircraft, and flap lift is part of the aircraft maintenance. During the work, the flap handle device is connected with the aircraft flap transmission shaft, and the handle is turned to make the aircraft flap lift up and down for inspection and maintenance. The current situation of the aircraft flap handle device is as follows. The flap handle is fixed at the corresponding position of the aircraft through the fixed locking mechanism, and the flap drive shaft is connected to the aircraft transmission shaft through the flap drive connection mechanism, and the flap drive shaft is driven by rotating the handle. Rotate, finally realize aircraft flap lifting. However, the existing ...
