A buffer spring is fixedly connected between the adjusting plate and the supporting ring, and a protective pad is fixedly arranged on one side of the outer part of the adjusting plate. Both sides below the supporting ring are fixedly provided with connecting plates. One end of the outer part of the multi-core steel pipe body is fixedly connected with a first connecting ring, and a clamping groove is formed on the surface of the first connecting ring.

[0003] During the use of the marine multi-core pipe steel pipe in the patent application, by using a fixed shaft to pull a pull rope under the action of rotation, forcing the positioning shaft to compress the return spring and slide into the moving groove, the fixed connection between the first connecting ring and the second connecting ring is released, which is convenient for disassembly.
