The working principle and use flow of the invention: first, the positioning rod 3 is inserted into the corresponding positioning groove 23, and then the T-shaped rotating inner rod 16 is manually rotated, so that the fixed outer rod 15 is driven to rotate the fixing stud 17 under the limiting effect of the second limiting slider 14, and at the same time, the second limiting chute 13 slides along the second limiting slider 14.

When the assembled building staircase main body 22 is used, when the external 502926 vibration is generated, the first seismic isolation spring 5 is elastically deformed, the sliding block 4 slides along the connecting guide post 11, the connecting outer rod 9 rotates along the sliding block 4 under the action of the rotating shaft 10, the connecting outer rod 9 moves along the inside of the positioning outer rod 8, and the third seismic isolation spring 7 is elastically deformed to play an effective seismic isolation role.
