[0024] During operation, one of the above technologies is applied to the tire maintenance device of the aviation industry. Although it is convenient to clean the tire surface, due to the heavy weight of the aviation industry tire itself and the limited space for the tire to move on the bottom plate, in the process of removing the tire from the storage shaft, it is necessary to avoid the tire from causing damage to other parts on the bottom plate, which inevitably requires more manpower. Through the structural design of the clamping mechanism, the function of facilitating the removal of the tire main body 21 from the storage shaft 22 is achieved. When the tire main body 21 placed on the storage shaft 22 is to be removed, the threaded rod 27 is first driven to rotate by the servo motor 28, and the first moving block 23 and the second moving block 25 threadedly connected to the threaded rod 27 will move in the same direction on the threaded rod 27.

The limit groove 39 is designed in a long rectangular shape and its size is adapted to the limit block 40. The limit groove 39 is provided on the inner wall of the through groove 36.

[0026] During operation, through the structural design of the limit groove 39 and the limit block 40, the guiding function of the first moving block 23 and the second moving block 25 when moving on the threaded rod 27 is realized, so as to ensure that the first moving block 23 and the second moving block 25 can move stably on the threaded rod 27, and through the contact between the limit block 40 and the inner wall of the limit groove 39, the bearing capacity of the support plate 30 can also be improved.
