<p>A multi-folded full-automatic opening-closing umbrella comprises a frame, cloth, a middle rod set, an upper nest, a lower nest, a handle, an umbrella opening/closing transformation ratio mechanism disposed in the middle rod set, and an umbrella opening/closing driving mechanism disposed in the handle and the middle rod set. The umbrella opening/closing driving mechanism drives the middle sleeve of the middle rod set to move up and down relative to the inner sleeve, and linkage opening/closing functions of the sleeves of the middle rod set and the cloth are realized at the same time.</p> |
