Problems solved by technology
[0003] Stairs are an essential facility in multi-storey buildings. At present, the stairs mainly include cement steps, wooden steps, or metal steps, etc., but no matter what kind of stairs, they are all ladder-like. There are limitations. When going up and down the stairs, pedestrians can only go up or down step by step. This is perfectly fine for people with normal health, but for people with inconvenient lower limbs, they use wheelchairs instead of walking. In this way, it is impossible to go up and down the stairs. Even normal people, when they are dragging items such as luggage carts or bags, it is more laborious to go up and down the stairs of this step type; Stairs for walking are very necessary

specific Embodiment approach
[0060]The specific embodiment: when people use the stairs designed by the present invention, under normal conditions, the stair plate is in a horizontal state, and in this case, the stairs can be used as normal stairs; When the drive disc 17 is rotated, the drive disc 17 will drive the drive worm 15 to rotate, the drive worm 15 will drive the drive worm 21 to rotate, the drive worm 21 will drive the corresponding gear shaft 30 to rotate, and the gear shaft 30 will drive the corresponding gear shaft 30 to rotate. The adjustment wheel 28 rotates. During the rotation of the adjustment wheel 28, once the teeth 29 on the adjustment wheel 28 mesh with the corresponding drive gear 23, the rotation of the adjustment wheel 28 will drive the corresponding drive gear 23 to rotate; the drive gear 23 rotates Drive the drive shaft 27 to rotate, and the rotation of the drive shaft 27 will cause the scroll spring 34 to exert force. The rotation of the drive shaft 27 drives the corresponding dr...
