Telescopic pedal type hanging ladder

The invention relates to a hanging ladder and provides a telescopic pedal type hanging ladder aiming at the defect that the conventional hanging ladder is easily collided with a material pile or raised ground so as to be damaged. The telescopic pedal type hanging ladder comprises a hanging ladder, wherein the hanging ladder comprises a left upright post and a right upright post positioned on two sides, a plurality of stages of pedals which are vertically arranged at intervals and are fixedly arranged between the left upright post and the right upright post, a return spring and a mounting device used for mounting the pedal type hanging ladder, wherein the mounting device comprises a guide device for guiding in the vertical direction; the hanging ladder comprises a sliding device which is arranged on the guide device in a sliding mode and drives the left upright post and the right upright post to slide up and down in the vertical direction; and the return spring provides an upward elastic force for the sliding device, so that the hanging ladder slides upwards without an external force. When the telescopic pedal type hanging ladder is not used, the hanging ladder can be lifted upwards, the height between the bottommost pedal and the ground is increased, and the hanging ladder is prevented from being easily collided with a material pile or raised ground so as not to be damaged.
