The surface is not sealed, the connecting block 22 rotates with the rotating shaft as the rotation center and drives the upper escalator cover 26 to move forward and backward. The upper escalator cover 26 adjusts its height while moving forward and backward. The upper escalator covers 26 on both sides are connected with pedals 6 through connecting columns 223. The distance between the positioning columns 222 and the slider 21 is adjusted by the swing of the connecting block 22, so that the upper escalator cover 26 moves up and down. The lower end of the upper escalator cover 26 is connected with an adapter block 23, and the lower end of the adapter block 23 is hinged to the lower escalator 5.
