The invention belongs to the technical field of swings, and particularly relates to a swing capable of being arranged in narrow space. The swing comprises a cross rod, swinging mechanisms and a seat plate, wherein the lower ends of two vertical rods are fixedly mounted on the ground; the cross rod is mounted on the two vertical rods; the two swinging mechanisms are symmetrically distributed relative to the central plane of the two vertical rods and are both mounted on the cross rod; the upper end surface of the seat plate is fixedly mounted at the lower ends of the two swinging mechanisms. When the space of a place is limited, the swinging height of the swing is limited, at the moment, an electric motor drives a drive sleeve to move, the drive sleeve can drive a drive shaft to move, the drive shaft can drive a drive gear to move, the drive gear can drive a spiral rail to move, the spiral rail can drive a fixed tube to move, and the swinging direction of a connecting rope is opposite tothe swing direction of the fixed tube at the moment, so that at the moment, the swing mounting space can be taken into consideration while demands of players for excitement feeling are met.
