The invention discloses soft display equipment, a support device and a double-axis hub module. The soft display equipment comprises a holding plate, two support devices and a soft display screen, wherein the two support devices are mounted on two opposite side surfaces of the holding plate; each support device comprises a double-axis hub module and two buffer modules which are positioned on two opposite outer sides of the double-axis hub module; each double-axis hub module comprises two shaft rods, a linking part which is clamped between the two shaft rods, and two side wing parts which are mounted on the two shaft rods in a sliding manner respectively; the two buffer modules are respectively mounted on the two shaft rods and are matched with two side wing parts respectively; each buffer module comprises an inner connecting part which is fixed on corresponding shaft rod and is synchronously rotated with the corresponding shaft rod, and an outer connecting part which is fixed on the inner surface of the holding plate and is arranged at the inner connecting part in a relative sliding manner; each side wing part comprises a limiting part which penetrates through the corresponding inner connecting part and the outer connecting part. Therefore, the outer connecting part and the inner connecting part of each buffer module are moved relatively, and the soft display screen can be prevented from being bent or damaged.
