The invention discloses a passenger boarding ladder capable of automatically adjusting angles of a platform and steps. The passenger boarding ladder comprises an opposite machine platform, a lifting device, a chassis, a main ladder body beam, an auxiliary ladder body beam, a connecting beam, a supporting beam and the steps. Wherein the connecting beam, the main ladder body beam, the auxiliary ladder body beam and the steps are hinged to one another to form a first hinge mechanism, and the first hinge mechanism is a parallelogram mechanism in the projection direction of the side face of the passenger boarding ladder; the connecting beams are parallel to the steps, and the main ladder body beams are parallel to the auxiliary ladder body beams; the machine aligning platform and the step are arranged in parallel; the chassis, the main ladder body beam, the connecting beam and the supporting beam are hinged to one another to form a second hinge mechanism, and the second hinge mechanism is an inequilateral four-bar mechanism in the projection direction of the side face of the passenger boarding ladder. And the lifting device is respectively hinged with the opposite machine platform, the main ladder body beam and the chassis.
