Full-automatic folding umbrella that opens and shuts

The utility model provides a full-automatic folding umbrella that opens and shuts, during the parachute-opening, the one hand is grip elasticity tight in one's hands and is controlled the shell, and the alternately flexible actuating lever upward movement of pin joint pole is replaced in inside roof pressure quadrangle bogie deformation, and two fixed blocks impose inward clamp force to two actuating levers, the extension of whole alternately pin joint pole group, promotion activity nest drives and respectively supports the bone and support each main chute bone gradually and expand, and thin footpath pipe stretches out from the particle size is intraductal gradually simultaneously, struts completely until the umbrella face, and the umbrella pole extends completely, and positioner fixes a position the state that the umbrella strutted, when closing the umbrella, shift knob is pressed to the one hand, opens positioner, and under the tension of pressure spring, alternately pin joint pole group shortens, the downstream of activity nest, and the main chute bone drives the umbrella face and gradually folds up, and it is intraductal that the indentation particle size is managed in thin footpath, folds up completely until umbrella face and rib, and it is intraductal that complete indentation particle size is managed in thin footpath. Therefore, the utility model discloses only need the one hand can realize the operation of opening and shutting, it is more convenient to use, and novel structure is reasonable, and the flexible operation is simple, and the practicality is strong.
