Further, the flap stopper 60 of the present embodiment includes a flap portion 61 and a fixing portion 62. Wherein, the fixing part 62 is connected to the side of the footpath 30, and the fixing part 62 can be fixed on the side wall of the footpath 30 by screws or pins, so as to realize the fixed connection of the fixing part 62 and the footpath 30.

The flap part 61 is rotatably connected to the top of the fixing part 62, and the fixing part 62 and the flap part 61 form a hinge structure. The turning part 81 rotates relative to the fixing part 62 or the footpath 30, and the included angle between the turning part 61 and the fixing part 62 changes correspondingly. In the present embodiment, the flap portion 61 and the fixing portion 62 are rotatably connected by a rotating shaft, and a rotation axis of the flap portion 61 is aligned with a length direction of the frame 20, that is, an extending direction of the rotating shaft is aligned with the length direction of the frame 20.

When the handrail 50 is assembled with the walkway 30, the connecting portion 52 is inserted into the sidewall of the walkway 30, and the fixing portion 62 is provided with a through hole at a position corresponding to the connecting portion 52, through which the connecting portion 52 of the handrail 50 passes.
