In other embodiments than the one described above, the number of connecting cords 35 is four, with eight ends being evenly distributed around the support ring 10, and the middle of each of the four connecting cords 35 being connected to one end of a pulling cord 40.

Further, the eight-character connecting ring comprises a eight-character connecting ring 3, a first connecting ring 4 and a second connecting ring 5 are arranged at two ends of the eight-character connecting ring 3 respectively, first annular knots 6 are arranged at two ends of a connecting rope 35, the connecting rope 35 is sleeved on the support ring 10 through the first annular knots 6, a second annular knot 7 is arranged in the middle of the connecting rope 35, the connecting rope 35 is connected with the first connecting ring 4 through the second annular knot 7, a third annular knot 8 is arranged at one end, close to the connecting rope 35, of the traction rope 40, and the traction rope 40 is connected with the second connecting ring 5 through the third annular knot 8.

In this embodiment, the splayed connecting ring 3 is made of stainless steel, and has a first connecting ring 4 and a second connecting ring 5 at two ends thereof. The first loop knot 6 is formed by bending the end of the connecting string 35 into a loop shape and then fixing the loop by welding a stainless steel sheet. The second loop knot 7 is made by bending the middle part of the connecting rope 35 into a loop shape and then welding and fixing the loop shape by stainless steel sheets. The third loop 8 is formed by bending the end of the pulling rope 40 into a loop and then welding and fixing the end by a stainless steel sheet. The connecting rope 35 is sleeved on the support ring 10 through the first annular knot 6, the connecting rope 35 is connected with the splayed connecting ring 3 after the second annular knot 7 and the first connecting ring 4 are sleeved with each other, and the connecting rope 35 is connected with the splayed connecting ring 3 after the third annular knot 8 and the second connecting ring 5 are sleeved with each other. The splayed connecting ring 3 has the characteristic of being rotatable. Because the ends of the hauling ropes 40 remote from the connecting ropes 35 are fixed on the hull, the net body 30 and the support ring 10 are free in the water, so that the hauling ropes 40 and the net body 30 and the support ring 10 can rotate relatively. The rotatable splaying attachment ring 3 is able to effectively counteract this relative rotation.
