The present invention reveals a Single-Handedly Foldable Stroller that includes a Hand Tube, a Front Leg Tube, a Front Helm, a Rear Leg Tube, a Rear Helm, and 2 Joint Components. Said Joint Components connect the Hand Tube, the Front Leg Tube and the Rear Leg Tube with each other. Each said Joint Components includes an Upper Joint, a Lower Joint, a Sleeve, a Sleeve Limiting Pedestal and a Folding Operation Component. The Upper Joint is connected with the Hand Tube, and the Lower Joint is connected with the Front Leg Tube. One end of the Sleeve is inserted in the Sleeve Limiting Pedestal, while the other end is sleeved in the Rear Leg Tube. Moving the Sleeve through the Folding Operation Component would gradually turn the Upper Joint and the Lower Joint counter-clockwise, accomplishing the folding/expanding of the Stroller.
