The utility model relates to the technical field of softboxes, and particularly discloses a folding softbox which comprises a supporting rod, the bottom of the supporting rod is connected with a check block, the bottom of the outer portion of the supporting rod is sleeved with a lifting block and a first damping sleeve, and a plurality of supporting legs are movably installed on the lifting block through a first damping shaft. The top of the exterior of the supporting rod is sleeved with a supporting component, the supporting component comprises a supporting plate, the two ends of the top of the supporting plate are connected with bearing plates, the tops of the opposite sides of the two bearing plates are connected with second damping shafts, and the second damping shafts are sleeved with second damping sleeves. The lifting frame is pulled downwards through the supporting component to move downwards outside the two bearing plates, at the moment, the spring is compressed, the photography lamp and the softbox base body are rotated to be in a vertical state from a horizontal state, pulling of the lifting frame is stopped, the spring is reset to drive the lifting frame to move upwards to reset, and the softbox base body is bound through the lifting frame.
