The adjusting mechanism includes a mounting frame 6, a threaded rod 7, a connecting rod 8, a connecting plate 9 and a bearing 10. The outer surface of the mounting sleeve 2 is fixedly connected with the mounting frame 6. The inside of the mounting frame 6 is threadedly connected with the threaded rod 7. Both ends of the threaded rod 7 penetrate through the mounting frame 6. The end of the threaded rod 7 away from the bearing 10 is fixedly connected with a knob 11. The bottom end of the threaded rod 7 is fixedly connected with the bearing 10. The outer surface of the clamping seat 5 is fixedly connected with the connecting rod 8. The outer surface of the connecting rod 8 is slidably connected with the mounting sleeve 2. The number of the connecting rods 8 is two and they are symmetrically distributed. The end of the connecting rod 8 away from the clamping seat 5 is fixedly connected with the connecting plate 9. The outer surface of the bearing 10 is fixedly connected with the connecting plate 9. When it is necessary to fix the cable, first pass the cable through the mounting sleeve 2, and the cable is in contact with the supporting seat 3. The protective pad 4 is used to reduce the wear on the outer surface of the cable when passing through the mounting sleeve 2. Then hold the knob 11 and rotate the threaded rod 7. The threaded rod 7 is screwed with the mounting frame 6. Then the threaded rod 7 moves towards the mounting sleeve 2 while rotating. Under the action of the bearing 10, the threaded rod 7 pushes the connecting plate 9 to move. Then the connecting plate 9 drives the connecting rod 8 to slide, so that the connecting rod 8 pushes the clamping seat 5 to approach the supporting seat 3 until the clamping seat 5 and the supporting seat 3 clamp and fix the cable, so as to improve the stability of the cable during the traction process in water and prevent the cable from falling off when fixed on the steel wire rope body 1.

The material of the connecting pad 13 is rubber. The number of the springs 15 is six and they are arranged in a circular array. When the cable passes through the mounting sleeve 2, it also passes through the fixing ring 12. Under the elastic force of the spring 15, the inner wall of the elastic ring 14 is in contact with and presses the outer surface of the cable, thereby further improving the stability of the cable when fixed.

[0025] Working principle: When it is necessary to fix the cable, first pass the cable through the fixing ring 12 on one side and enter the mounting sleeve 2, so that the cable is in contact with the supporting seat 3. Then hold the knob 11 and rotate the threaded rod 7. The threaded rod 7 is screwed with the mounting frame 6. Then the threaded rod 7 moves towards the mounting sleeve 2 while rotating. Under the action of the bearing 10, the threaded rod 7 pushes the connecting plate 9 to move. Then the connecting plate 9 drives the connecting rod 8 to slide, so that the connecting rod 8 pushes the clamping seat 5 to approach the supporting seat 3 until the clamping seat 5 and the supporting seat 3 clamp and fix the cable, so as to improve the stability of the cable during the traction process in water and prevent the cable from falling off when fixed on the steel wire rope body 1, and the operation is simple and convenient. Finally, pass the cable through the fixing ring 12 on the other side. Finally, it is towed and laid through the steel wire rope body 1.
