The invention discloses a fin underwater device for preventing a cable from being bent. The fin underwater device comprises a shell; the notch is formed in the side part of the shell; the rotating shaft is rotationally arranged in the notch, and a first driving mechanism used for driving the rotating shaft to rotate is connected to the rotating shaft; the fin bracket is arranged on the rotating shaft; the fish fin is rotationally arranged on the fish fin bracket, and a second driving mechanism for driving the fish fin to rotate is connected to the fish fin; and the cable interface is arranged on the rotating shaft and is used for being electrically connected with the second driving mechanism. Compared with the prior art, the device has the beneficial effects that motion integration of the fins in two directions is realized, the flexibility of the underwater vehicle is greatly improved, and meanwhile, by optimizing the structural design, the fins cannot bend and extrude the connected cables in the periodic mov
