Further, on the basis of the above-mentioned embodiment, the circumferential surface of the first rotating part 3 is provided with the positioning ring groove 31, and because in the pulling and applying process and the using process of the cable, when the cable falls onto the first rotating part 3, the cable can always slide into the positioning ring groove 31 under the action of the gravity of the cable, the cable is prevented from moving along the axial direction of the first rotating part 3 when being arranged on the first rotating part 3, so as to control the unnecessary movement of the cable.

Further, on the basis of the above-mentioned embodiment, the central line of the first positioning rod 2 is horizontally arranged, when the first positioning rod 2 is used for supporting a cable, the cable is prevented from sliding on the circumferential surface of the first positioning rod 2 due to the inclined arrangement of the first positioning rod 2, and the stability of the cable moving process on the first positioning rod 2 is further improved.

Further, on the basis of the above embodiment, the base 1 is provided with the threaded fastener 12, the threaded fastener 12 is in threaded connection with the base 1, and is used for adjusting the tightness between the base 1 and the bulwark by rotating the threaded fastener 12 when the clamping position 13 is fixed on the bulwark, so as to facilitate quick assembly and disassembly and improve the cable laying efficiency.

Example 2

As shown in fig. 3 to 4, based on the same inventive concept, the longitudinal protection part 4 includes a base 41 and a fixing rod 42, the base 41 is fixed on the first positioning rod 2, the fixing rod 42 is disposed on the base 41, an arc-shaped part 421 is disposed in the middle of the fixing rod 42, and the distance between the two arc-shaped parts 421 is greater than the distance between the two fixing rods 42.

Through set up arc portion 421 in the middle part of dead lever 42, and then increase the distance between two dead levers 42, when the cable was located between two dead levers 42, through the space that two arc portions 421 reserves, avoid producing the friction damage between cable and the dead lever 42.

Further, on the basis of the above embodiment, two top portions of the longitudinal protection portions 4 are provided with the connecting rods 6, the connecting rods 6 are provided with the hook portions 7, the hook portions 7 are rotatably arranged on the connecting rods 6, and when the special tool cannot find the clamping positions 13 suitable for the base 1 to be fixed, the special tool can be hooked on the ship body through the hook portions 7, so that the applicability of the special tool in mounting and using is further improved, the mounting requirements of the base 1 on the bulwark or the ship body are reduced, and the usability is improved.

And, it is worth saying that the hook portion is arranged on the connecting rod, and the hook portion is rotatable, and when the hook portion is arranged on the hull, the relative position and angle between the hook portion and the connecting rod can be adjusted in order to adapt to different positions of the ship and the cable, so that the situation that the position of the first rotating portion is fixed to influence the stability of the cable pulling and laying is avoided.
