Convenient ladder

Convenient ladder designs a double layers ‘toolbox on the top of the recent ladder, and basically covers most commonly used tools. This satisfies the basic needs of the construction workers, and greatly improves the efficiency and convenience of the work. Moreover, the toolbox automatically rotates into the horizontal and vertical degree with the opening and closing of the ladder. It does not occupy the space, and is also used a console for placing tools temporarily.
