[0002] Due to the limited height of human beings, when it is necessary to work at height, the operator must rely on the assistance of an auxiliary ladder to climb to a high place. After investigation, it is found that the general traditional ladder is generally composed of a standing board and a pair of ladder frames pivotally connected to the bottom of the standing board. When in use, the ladder frames must be expanded outward to form a ladder with an appearance similar to "A" so that the operator can climb up. However, although the above-mentioned traditional ladder can be used for the operator to climb, the area of the standing board is only enough for a single person to stand. Therefore, the operator's activity space on the ladder is extremely limited. When it is necessary to move horizontally to change the working location, the operator must first leave the ladder before moving the ladder to a suitable location to continue working. This can be said to be a considerable trouble and problem for the operator.
