The invention discloses a portable ladder for an electric pole. The portable ladder mainly comprises a telescopic ladder frame, wherein ladder poles at two sides of the ladder frame are respectively connected with two upper and lower support pole frames via pin shafts; the end parts of two upper support pole frames and two lower support pole frames of a beam ladder pole are respectively connected with a front support rod, and the connection end parts are connected with a knotted sleeve which can be bound to the electric pole; the front support poles are sleeved by antislip sleeves; the knotting sleeves are connected with pull rope tapes at the end parts of the support pole frames and the tightener in the middle; the support pole frames are connected to the two ladder poles of the ladder frame via a central pin shaft, and are fixed on the pin shafts at the outer side of the ladder poles via nuts or bolts. The portable ladder has the characteristics of simple structure, convenience in use, safety, reliability, capability of being applicable to electric poles (columns) with insulators or porcelain bottles at the upper sections and the like.
