The invention discloses a folding automatic entrance door. A shape adjustable triangular support is formed by a support rod and a first door leaf and a second door leaf of the folding automatic entrance door. The driving rod can draw the support rod to conduct gesture change and adjust the shape of the triangular support through the gesture change of the support rod to further enable the included angle between the first door leaf and the second door leaf to change with the shape change of the triangular support and drive the first door leaf and the second door leaf to stretch in a folding mode. Further, drawing force is generated in the intersection direction of the driving rod and the support rod to prevent locking in the drawing process of the support rod. The first door leaf and the second door leaf are connected through a folding mechanism in a rotating mode and can wrap the arc outer circumferential face of the folding mechanism and move, so that pinching of the finger can be effectively avoided in the folding door closing process. In addition, the folding automatic entrance door has a multi-point prying-resistant function.
