This can solve the problem that when people use the folding ladder, the bottom layer of the folding ladder generally does not contact the ground, which makes the folding ladder need to bear the weight of all people when in use, and is extremely easy to be damaged during use. At the same time, the folding ladder that is partially in contact with the ground is easy to be unable to be smoothly built or laid on the ground due to the instability of the ground.
