Towing cable supporting mechanism

The invention discloses a towing cable supporting mechanism which comprises a contact part, a top supporting rod, a direction limiter, a main supporting rod, a motor and a battery. The contact part iscomposed of a top arc piece and a ball and is in direct contact with a communication cable, and a submarine communication cable is lifted through the main supporting rod. The contact part is connected with the direction limiter through the top supporting rod, and the shape of the cable is limited under the condition that free movement is guaranteed. A cable of a communication buoy has the risk oftouching a submarine tail vane in the deep diving communication process of a submarine, the rudder effect and the service life of the cable are influenced, and even the safety of the submarine is threatened. The submarine communication buoy cable support mainly plays a role in lifting the submarine underwater communication cable. After the submarine is unwound, the supporting rod is controlled toascend and descend, the fi
