Anti-skid ladder

The utility model relates to a ladder, in particular to an anti slipping ladder without manual holding, which comprises a ladder. The utility model is characterized in that small suction disks are tightly connected on the identical side at the upper end of the left and the right legs of the ladder, big suction disks are tightly connected on the lower end surface of the left and the right legs, the small suction disk and the big suction disk adopt rubber bodies of the structure that the upper part is small, the lower part is big, and the middle part is hollow. The small suction disks are tightly connected on the identical sides at the upper ends of the left and the right legs of the ladder, and the big suction disks are tightly connected on the lower end surfaces of the left and the right legs, therefore the frictional force and the suction force between the suction disks and objects are increased, to ensure the ladder not to be moved under normal conditions, suction disks adopting rubber bodies of the structu
