The first extraction handle is the same as the second extraction handle, and the extraction plate can abut against the dustproof leather bowl of the aircraft wheel.

[0014] Preferably, the support assembly comprises:

[0015] The support rod is connected with one end of the vertical rod at the middle part.

[0016] The support sliding block is arranged in the hub and connected with the U-shaped groove at two ends of the support rod.

[0017] Preferably, the device further comprises:

[0018] A rotating handle for connecting the vertical rod to the middle of the support rod.

[0019] Preferably, one end of the vertical rod is provided with a thread, and one end of the first extraction handle is provided with a thread.

[0020] The beneficial technical effects of the present application are:

[0021] The present application provides an aviation wheel dustproof skin bowl non-destructive extraction device, which has a simple structure and solves the problems of frequent scrapping and damage to the hub caused by disassembly of the aviation tire dustproof skin bowl. The device is suitable for different models and different types of wheels. BRIEF DESCRIPTION OF DRAWINGS

[0022] Figure 1 is a structural schematic diagram of an aviation wheel sealing skin bowl non-destructive extraction device provided by an embodiment of the present application;

[0023] Figure 2 is an application state diagram of an aviation wheel sealing skin bowl non-destructive extraction device provided by an embodiment of the present application;
