[0048] In this embodiment, the movable climbing pole 16 can be climbed normally when the telescopic ladder section 20 is unfolded. When the telescopic ladder section 20 is retracted, the movable climbing pole 16 on one side can be brought close to the movable climbing pole 16 on the other side, and finally the locking blocks 21 on the movable climbing poles 16 on both sides are brought into contact. The lock hole 22 can be locked by a safety lock or other locking device, and the movable bolt 18 at the bottom of the climbing pole 1 can be inserted into the movable bolt groove 19, so that the movable climbing pole 16 is fixed.
