Referring to fig. 2 and 3, the connecting plates 5 for connecting the framework 1 are fixedly welded at the two ends of the tread 2, the connecting plates 5 are of angle steel structures, the connecting plates 5 are divided into fixing portions 51 and connecting portions 52 which are perpendicular to each other, the fixing portions 51 of the connecting plates 5 are welded with the tread 2 towards one side wall of the lower end of the stair, and the connecting portions 52 are rotatably connected with the framework 1 through pin shafts 53. In the vertical direction, the step plate 2 is located below the framework 1.

Referring to fig. 2 and 4, a cross bar 6 perpendicular to the push rod 3 is connected between two connecting plates 5 on the same footboard 2, and the distance from the connecting point of the cross bar 6 and the connecting plates 5 to the footboard 2 is greater than the distance from the pin shaft 53 to the footboard 2. Each cross rod 6 is arranged on the push rod 3 in a penetrating way and moves along with the movement of the push rod 3, and the cross sections of the cross rods 6 and the cross sections of the push rods 3 are circular, so that the cross rods 6 can rotate on the push rods 3 relatively. An adjusting component 7 for controlling an included angle between the tread plate 2 and the tread surface is arranged between the lower end of the push rod 3 and the cross beam 4 close to the end.

Referring to fig. 2, the adjusting assembly 7 includes a fixing rod 71, a connection sleeve 72, and an adjusting plate 73. The fixing rod 71 is in a horizontal state, and one end of the fixing rod 71 is welded and fixed at the middle position of the cross beam 4. Threads with opposite rotation directions are arranged at two ends of the inner wall of the connecting sleeve 72; two rotating handles 721 convenient for force application are fixedly welded on the outer wall of the connecting sleeve 72. A connecting rod 74 is vertically welded on one side wall of the adjusting plate 73 close to the fixing rod 71; both ends of the connecting sleeve 72 are respectively in threaded connection with the fixing rod 71 and the connecting rod 74.

Referring to fig. 2, an adjusting groove 731 for moving the push rod 3 in the vertical direction is formed on a side wall of the adjusting plate 73 away from the fixing rod 71. The section of the adjustment groove 731 is in an inverted T shape, and the length direction of the adjustment groove 731 is perpendicular to the ground. One end of the push rod 3 close to the adjusting plate 73 is fixedly welded with a sliding column 31 with a circular section, and the axis of the sliding column 31 is perpendicular to the axis of the push rod 3. The section of the adjustment groove 731 is an inverted T-shape, and the length direction of the adjustment groove 731 is perpendicular to the ground.
