When the hanging frame 1 lands on the ground with the wind power parts that need maintenance, the placement box 2 moves downward under gravity, and the telescopic rod of the shock absorber 4.1 drives the fixing ring 4.5 to move downward. Under the action of the connecting rod 4.6, the two moving blocks 4.3 move away from each other and force the buffer spring 4.4 to undergo elastic deformation. The buffer spring 4.4 can buffer and damp the vibration generated at the moment of landing.
