The invention belongs to the technical field of accommodation ladders for ships and discloses a portable flexible splicing ladder. The ladder comprises ladder frames and flexible connecting devices; and the adjacent ladder frames are rotatably connected through the flexible connecting devices. Each flexible connecting device comprises a connecting block, a pin shaft, a nylon lining body, a screw and a nut; the nylon lining body is fixedly arranged on one of the two adjacent ladder frames through the screw; the connecting block is fixedly arranged on the other ladder frame and corresponds to the nylon lining body; the connecting block extends towards the outer side of the edge of the ladder frame, and the extending tail end of the connecting block is rotatably connected with the nylon lining body through the pin shaft. Roller assemblies are arranged on the lower portions of the left sides and the right sides of the ladder frames; each roller assembly comprises a roller support, a bolt,a self-locking nut and a roller; an anti-disengagement device is arranged at the front end of the ladder frame at the head end. Therefore, the ladder has the advantages of simple structure, convenience in disassembly, suitability for various irregular slopes or curved surfaces, wide application range, high practicability and high safety.
