by arranging the splicing wire ring 22, when the communication cable for the underwater vehicle communication buoy is processed and operated, the splicing wire ring 22 with the corresponding number of threading grooves 21 is selected according to the caliber of the communication cable by utilizing the arrangement of the splicing wire ring 22 when the steel wire sheath 6 is twisted, the splicing wire ring 22 is fixed on the twisting disc 17 by utilizing the thread structure between the splicing wire ring 22 and the twisting disc 17, a user enables the polyethylene inner sheath 5 of the copper conductor 3 to pass through the circular through holes of the twisting disc 17 and the connecting rod 18, meanwhile, a bobbin provided with the steel wire is placed on the wire fixing column 19 of the rotating column 13, the connecting rod 18 is driven by the motor to drive the connecting rod 18 to enable the connecting rod 18 to drive the twisting disc 17 to rotate, when the polyethylene inner sheath 5 of the copper conductor 3 passes out of the middle part of the twisting disc 17, the steel wire threaded on the splicing wire ring 22 can be wound on the surface of the polyethylene inner sheath 5 by utilizing the rotation of the twisting disc 17, the processing operation of the steel wire sheath 6 is completed, the steel wire sheaths 6 with different calibers can be processed at will according to the calibers of the communication cable by utilizing the combined fixing structure of the splicing wire ring 22, the twisting processing operation of different numbers of steel wires is convenient, and the flexibility of the underwater vehicle communication buoy communication cable processing is improved;

by arranging the pressing clamping seat 12, when the communication cable for the underwater vehicle communication buoy is processed and operated, the communication cable wound with the steel wire sheath 6 can pass through the pressing clamping seat 12, according to the caliber of the steel wire sheath 6, a user can drive the elastic roller 24 to move by rotating the threaded sleeve 27, the three groups of the elastic rollers 24 can extrude the steel wire sheath 6 of the communication cable from three directions by moving the positions of the three groups of the threaded sleeves 27, the elastic roller 24 is provided with an elastic pressing structure by utilizing the spring columns 26 between the telescopic rods 25 and the threaded sleeve 27, the elastic roller 24 is matched with the arrangement of the rolling base 23, when the steel wire sheath 6 of the communication cable is output, the steel wire sheath 6 is extruded and reinforced from the periphery of the steel wire sheath 6, the steel wire sheath 6 is wrapped more firmly, the arrangement of the pressing clamping seat 12 is utilized, and the production link of the communication cable for the underwater vehicle communication buoy can be realized, make 6 parcels of steel wire sheath more firm, avoid it to appear not hard up phenomenon of droing, promote this communication cable's result of use.
