[0022] The effect achieved by the entire embodiment 1 is that, in the subsequent use process, the inner surface wall of the sealing semicircular ring 108 will first contact the outer surface of the sheath body 101, and the user will screw the first bolt 109 into the corresponding first threaded hole 110 and the inside of the fixing block 111 to limit the sealing semicircular ring 108. Then the sliding rod 106 and the compression spring 107 will feel the pressure, thereby changing their own state. Then, the subsequent sealing semicircular ring 108 can use the expansion force of the compression spring 107 and the force of the first bolt 109 being screwed in to achieve more powerful pressure on the sheath body 101. In addition, in the actual use process, the sealing semicircular ring 108 will be on the two sheath bodies 101, and there will be no gap between the two sealing semicircular rings 108 to ensure the overall sealing.

[0023] Embodiment 2, as Figure 1-Figure 3 As shown, one end of the compression spring 107 is fixedly connected to the outer surface of the slide rod 106, and the other end of the compression spring 107 is fixedly connected to the outer surface of the sealing semicircular ring 108. The top of the fixing block 111 is located at the position of the first bolt 109 and is provided with a first threaded hole 110. The inner surface wall of the first threaded hole 110 is threadedly connected to the outer surface of the first bolt 109. The inner surface of the sealing semicircular ring 108 is slidably connected to the outer surface of the sheath body 101. The inner surface of the aluminum foil shielding layer 104 is fixedly connected to the PP wrapping tape 113. The inner top and inner bottom of the PP wrapping tape 113 are fixedly connected to the filling piece 112. The PP wrapping tape 113 is fixedly connected to the inner top and inner bottom of the PP wrapping tape 113. Insulating parts 114 are fixedly connected to both sides of the inner surface of the belt 113, and a conductor 115 is fixedly connected to the center of the inner surface of the insulating part 114. The auxiliary structure 2 includes a connecting part 201, and a second bolt 203 is threadedly penetrated at the center of the top of the connecting part 201. A second threaded hole 202 is provided at the top of the connecting part 201 at the position of the second bolt 203. The inner wall of the second threaded hole 202 is threadedly connected to the outer surface of the second bolt 203. The bottom end face of the second bolt 203 is threadedly penetrated through the surface of the fixing seat 102, and the outer surface of the connecting part 201 is fixedly connected to the outer surface of the circular part 105.

[0024] The effect achieved by the entire embodiment 2 is that the second bolt 203, the connecting piece 201 and the second threaded hole 202 cooperate with each other to achieve the effect of fixing and limiting the circular piece 105. The secondary limitation ensures that the sealing semicircular ring 108 can always be stably on the sheath body 101, and the PP wrapping tape 113 can play a role of heat insulation or anti-corrosion.

[0025] Working principle: After the user connects the guide wire with the external cable, the user can put the sealing semicircular ring 108 into the connection, and then the user manually screws the first bolt 109 into the corresponding first threaded hole 110 and the inside of the fixing block 111. After screwing in, the sealing semicircular ring 108 can be limited, and the sliding rod 106 and the compression spring 107 will feel the pressure, thereby changing their own state to a compressed state. The sealing semicircular ring 108 can use the expansion force of the compression spring 107 and the force of the first bolt 109 being screwed in, so that its inner surface can fit the outer surface of the cable more closely, thereby improving the overall sealing. Then the user screws the second bolt 203 into the corresponding second threaded hole 202 and the connecting piece 201, and finally the second bolt 203 can be screwed into the inside of the fixing seat 102 to achieve secondary limiting of the circular piece 105.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
