Abstract: The present invention relates to a single hand folding structure for an umbrella folding stroller (2), utilizing a connecting element to connect between a single hand release structure and locking elements of a folding set. Wherein the single hand release structure is disposed on the handle bar of the frame of the umbrella fold stroller so as to allow a user to directly operate with hand to release the folding set. Meanwhile, a device on an elastic element of the frame is utilized to assist the partial folding of the frame such that the user can directly push the handle bar to fold the frame. Thus, the user avoids using her foot to release the frame to fold and subsequently prevents damage to her shoe.
