Abstract

The present invention relates to a retractable ladder that includes a plurality of ladder posts, connection members, locking mechanisms and horizontal ladder boards, wherein the each ladder post is a hollow sleeve in which the diameter is smaller when the position is higher. The upper ladder post can be put into the lower ladder post with each other. The connection member is horizontally put on the ladder post to enable the locking mechanism disposed to the inside to timely hook the fastening hole of the ladder post, so that each ladder post can be extended and fixed. The exterior of the ladder post can be covered by the horizontal ladder board. Since the locking mechanism is improved, the retractable ladder may not loosen due to the pressing imposed by the external force, thereby ensuring the safety use.
