A mechanical expansion shaft comprises a rotating shaft and multiple supporting tiles, and is characterized in that the mechanical expansion shaft further comprises a supporting tile automatic expanding mechanism; a locating shaft is arranged on the bottom face of each supporting tile; slidable rods are arranged at the two ends of each locating shaft; the supporting tile automatic expanding mechanism comprises two supporting tile automatic expanding units; and each supporting tile automatic expanding unit comprises a limiting part and at least one acting part. The invention discloses an application method of the mechanical expansion shaft. Compared with the prior art, the mechanical expansion shaft has the beneficial effects that due to the fact that the structure is improved, automatic expanding can be achieved during winding, the winding state and the expanding state are kept so as to wind a thin film, the mechanical expansion shaft can be easily converted into the storage and closing state when not used, a
