by arranging the extrusion block 21, when the pulling force between the cable 11 and the corresponding guide connection monomer 35 is large, the cable 11 can enable the guide connection monomer 35 to move to the position corresponding to the winding drum 2, and then the extrusion block 21 fixed on the surface of the winding drum 2 can extrude the corresponding compression ring 31, so that the compression ring 31 moves towards the surface of the corresponding guide connection monomer 35, the compression ring 31 can drive the corresponding fixed block 33 to rotate, and further the fixed block 33 can loosen the fixation of the corresponding cable 11, and the automatic adjustment of the tightness between the guide connection monomer 35 and the corresponding cable 11 is realized; by arranging the first telescopic rod 23 and the second telescopic rod 26, when the cable 11 is pulled outwards to correspond to the winding drum 2, the winding drum 2 can slide in the corresponding fixing ring 22, and then the winding drum 2 can compress the corresponding first telescopic rod 23, so that the gas in the first telescopic rod 23 enters the corresponding second telescopic rod 26, the second telescopic rod 26 further drives the corresponding limiting ring to guide out the corresponding limiting groove, the cable 11 on the surface of the winding drum 2 is further fixed through the limiting block 25, the sliding risk of the cable 11 on the surface of the corresponding winding drum 2 is reduced, and the use stability of the guiding connector is improved; the sealing grooves are formed in the guide holes, and the sealing rings 14 are arranged in the multiple sealing grooves, so that the multiple sealing effect on the guide holes is realized, the inside and the outside of the sealing shell 1 are fully isolated, and the phenomenon that water penetrates into the inside of the sealing shell 1 under the underwater condition to cause the guide connector to be incapable of working normally is avoided; through all seting up sealed chamber in the inside at sealing ring 14, when reel 2 received corresponding cable 11 external pulling force, reel 2 compressed first telescopic link 23 for the inside gas of first telescopic link 23 enters into the sealed intracavity portion of sealing ring 14 simultaneously, and then makes sealing ring 14 inflation, improves the sealed effect to the guide hole inside through expanded sealing ring 14, has reduced the endosmosis risk.
