Two sets of fixing seats 31 are symmetrically arranged on the front and rear end surfaces of the lower shell 2. Braking rods 32 are rotatably arranged in the fixing seats 31. Torsion springs 33 are wound around the surfaces of the braking rods 32. Threaded rods 34 are arranged on the top surfaces of the braking rods 32. Assembly seats 35 are arranged on the surface of the upper shell 1 above the threaded rods 34. The threaded rods 34 are rotatably connected to the assembly seats 35. Threaded blocks 36 are threadedly connected to the threaded rods 34. A turning handle 37 is rotatably arranged on the outer wall of the threaded block 36. A limiting groove 38 is arranged on the surface of the assembly seat 35 corresponding to the bottom surface of the turning handle 37.

[0022] When in use, first fit the upper shell 1 and the lower shell 2 on the submarine cable, then loosen the threaded rod 34, and use the restoring force of the torsion spring 33 to drive the brake rod 32 to return and rotate in the fixing seat 31, and make the brake rod 32 drive the threaded rod 34 to rotate into the assembly seat 35, then turn the handle 37, make the handle 37 rotate on the threaded block 36, and turn to the top of the threaded block 36, then use the handle 37 to drive the threaded block 36 to rotate on the threaded rod 34, and make the threaded block 36 rotate into the limiting groove 38, so that the upper shell 1 and the lower shell 2 need to be disassembled, by using the handle 37 to drive the threaded block 36 to rotate on the threaded rod 34, and make the threaded block 36 rotate out of the limiting groove 38, then the brake rod 32 is rotated in the fixing seat 31, and the threaded rod 34 is rotated out of the assembly seat 35, the purpose of disassembling the upper shell 1 and the lower shell 2 can be achieved.

[0023] In other embodiments, a movable bin 41 is disposed on the outer wall of the assembly seat 35, a connecting rod 42 is transversely disposed on the inner wall of the movable bin 41, a slider 43 is slidably disposed on the connecting rod 42, a spring 44 is wound around the connecting rod 42, a plug-in rod 45 is disposed on the top surface of the slider 43, and a plug-in groove 46 is provided on the surface of the threaded block 36 corresponding to the outer end of the plug-in rod 45;

[0024] When in use, first pull the plug rod 45 in the direction away from the assembly seat 35, so that the plug rod 45 drives the slider 43 to slide on the connecting rod 42, and the slider 43 continuously squeezes the spring 44, and the slider 43 synchronously drives the plug rod 45 to move, and then the threaded block 36 is rotated into the limiting groove 38, and the upper shell 1 and the lower shell 2 are installed until the plug groove 46 is aligned with the plug rod 45, and then the plug rod 45 is released, and the restoring force of the spring 44 is used to push the slider 43 to reset and slide on the connecting rod 42, and the plug rod 45 slides into the plug groove 46, so as to achieve the purpose of limiting the rotation of the threaded block 36, and prevent the threaded block 36 from loosening or rotating on the threaded rod 34, resulting in an unstable connection between the upper shell 1 and the lower shell 2.

[0025] In other embodiments, positioning posts 39 are provided on the outer wall of the lower shell 2 in the middle of the two sets of fixing seats 31, and positioning blocks 310 are provided on the outer wall of the upper shell 1 above the positioning posts 39, and the positioning posts 39 are slidably connected to the positioning blocks 310;

[0026] Through this design, the positioning block 310 can be driven by the upper shell 1 to be sleeved on the positioning column 39, so that the positioning block 310 and the positioning column 39 can achieve the purpose of positioning the upper shell 1 and the lower shell 2, so as to facilitate the staff to install the upper shell 1 and the lower shell 2, and prevent the upper shell 1 or the lower shell 2 from being displaced during the installation process, thereby affecting the installation progress of the upper shell 1 and the lower shell 2.

[0027] In other embodiments, multiple sets of sealing gaskets are disposed at the connection between the upper shell 1 and the lower shell 2, and the sealing gaskets are disposed on the surface of the upper shell 1 and the surface of the lower shell 2 respectively;

[0028] With this design, the sealing gasket can be used to increase the sealing performance between the upper shell 1 and the lower shell 2 to prevent seawater from entering the upper shell 1 and causing damage to the submarine cable in the upper shell 1.

[0029] In other embodiments, a rubber ring is sleeved on the outer wall of the turning handle 37, and the turning handle 37 drives the rubber ring to rub against the inner wall of the threaded block 36;

[0030] This design can ensure the stability of the rotation of the handle 37 in the threaded block 36, prevent the handle 37 from rotating randomly in the threaded block 36 and rubbing against the outer wall of the assembly seat 35, causing friction damage to the outer wall of the assembly seat 35 or the handle 37.

[0031] In other embodiments, the plug-in rod 45 is designed in an L-shape, and the plug-in slot 46 is provided as a countersunk hole adapted to the plug-in rod 45;
