Abstract
A ladder is revealed. A sliding rail is formed on a surface of one side of each of two ladder poles of a ladder body. At least one sliding block is mounted and sliding in the sliding rail of the ladder pole. An assembly member is arranged between the sliding blocks of the ladder poles. A ring on user's safety clothing is set on the center of the assembly member and connected to the assembly member during climbing. When the user falls off the ladder accidentally, the sliding blocks connected to the assembly member are also pulled so that the sliding blocks are inclined an angle and the braking end within the sliding rail is against the wall of the sliding rail for braking and slip resistance. Thereby the descending is slowed down and the ladder safety during climbing is improved.
