The invention discloses a puller special for ocean engineering. The puller special for ocean engineering comprises a cylinder and a driving screw arranged in the center of one end of the cylinder. One end of the driving screw is provided with a driving screw cap, and the other end of the driving screw penetrates through a bearing and straining beam and the center of one end of the cylinder and is located on the central axis of the cylinder. The driving screw is connected with a driving nut, a plurality of evenly-distributed circular holes are formed in the driving nut, and a puller rod used for hooking and pulling a pulled object is arranged in each circular hole. The puller rods are provided with bent portions, and the bent portions are arranged oppositely to form a circular truncated cone space with taper. A set nut with the same taper as the circular truncated cone space is arranged in the circular truncated cone space and is in threaded connection with the driving screw. Through the cooperation between the driving screw and the circular truncated cone space, opening and closing of a hook portion of the puller can be adjusted, and the hook portion of the puller can be firmly fixed to a pulled part. The puller special for ocean engineering can be used for drawing any part provided with an inner hole or an inner circular face and is more suitable for disassembly or assembly of underwater engineering equipment by operators under the water.
