The invention discloses an retractable scaffold, which comprises an independent tube or a plurality of branch tubes; wherein, each branch tube comprises at least two sections of retractable connection tubes, a first connection tube and a second connection tube; wherein, the second connection tube is inserted into and retractably connected with the first connection tube; a locking mechanism is arranged between the first connection tube and the second connection tube; a fixing piece is arranged at the lower end of the first connection tube; a connected joint base is arranged at the upper end of the second connection tube. Compared with the prior art, the connection tubes can be retractably sleeved together by adopting of the locking mechanism so that three-dimensional spaces and packing size can be saved, the cost is reduced and the safety of products can be enhanced by using the retractable scaffold.
