摘要： A double folding auto-expansion and folding umbrella has an umbrella shaft formed by a hollow first tube sheathing with a hollow second tube, a head fixed on the bottom of the hollow second tube, a control switch being installed on the head, a first nest fixed on the top of the hollow first tube; a second nest sheathing on the umbrella shaft and capable of lifting and moving along thereof, a supporting frame composed by a plurality of umbrella bones connecting to the second nest, and an umbrella cloth paved on the supporting frame. The first nest is connected to the hollow first tube, the supporting frame and the umbrella cloth. A retaining seat of the elastic pin is positioned in the about middle of the hollow second tube. An elastic hook is installed under the elastic pin. The elastic hook is connected to the control switch. Besides, the upper portion of the hollow first tube has a first buckling hole. An elastic buckle for buckling the first buckling hole is installed in the second nest. An elastic protrusion is installed in the below of the hollow second tube. A main elastic unit for closing the umbrella shaft is installed in the hollow first tube and the hollow second tube. One end of the main elastic unit is fixed in the first nest and another end thereof is fixed on the retaining seat.
