The invention provides a portable cable crimping platform. A vertical plate is mounted on a bracket; elephant-shaped press pliers and a power mechanism are mounted at two sides of the vertical plate; a press block is mounted in a groove formed in a second side plate in the elephant-shaped press pliers; the power mechanism comprises a screw rod and a piston cylinder; a piston rod is arranged at the right end of the piston cylinder; the piston cylinder and the piston rod are both ring-shaped; the middle part of the screw rod is connected with a fixed base through a threaded structure; the left end of the screw rod extends into the piston cylinder and the piston rod; the press block is of a two-layer structure comprising a first press block and a second press block; the first press block is provided with a through groove in which the second press block is arranged; a clamping structure is arranged between the through groove and the second press block; the right end of the second press block extends out of the first press block to get contact with the left end of the screw rod; the screw rod can drive the second press block to move horizontally alone; the right end of the first press block is in contact with the left end of the piston rod; the piston rod can drive the first press block and the second press block to move as a whole. The portable cable crimping platform is convenient to operate, is portable, is capable of cable crimping in many ways, and has relatively good crimping efficiency and crimping quality.
