[0002] Optical cable is the main transmission carrier of optical fiber communication, and its long-term operation reliability and service life are of great significance to the reliability of communication network. During long-term use, optical cable inevitably exists in a water vapor environment, and the water blocking performance of optical cable is an important indicator for evaluating the quality of optical cable, an important aspect for testing the environmental performance of optical cable, and one of the important factors for ensuring the 25-year service life of optical cable. For the above reasons, the requirements of communication system operators for the water blocking performance of optical cable are becoming more and more stringent, and it is one of the mandatory items for them to purchase optical cable.

[0003] In order to be able to produce optical cable with excellent water blocking performance, people have developed SZ stranded strength member threading tube to produce optical cable. However, there is a problem in the use of the current SZ stranded strength member threading tube, that is, the optical cable needs to inject grease into the SZ stranded strength member threading tube during production. However, due to the gap between the connector and the guide tube on the SZ stranded strength member threading tube, the grease will leak out from the gap between the connector and the guide tube. The leakage of the grease will not only pollute the workshop environment, but also cause the optical cable produced to have substandard grease content. SUMMARY

[0010] Optionally, the axes of the reinforcing member channels of the connector, the guide tube, the twisting gun head and the conical die are on a straight line.

[0011] Optionally, the reinforcing member channel of the twisting gun head is in the shape of a circular hole.

[0012] Optionally, the reinforcing member channel of the conical die comprises a plurality of circular truncated cone holes and a plurality of circular holes, and the circular truncated cone holes and the circular holes are detachably connected with each other.

[0013] Optionally, the twisting gun head comprises a main tube, a first side tube sleeve and a second side tube sleeve, the first side tube sleeve is detachably connected with the main tube through threaded connection, the conical die is connected with the first side tube sleeve, the second side tube sleeve is fixedly connected with the main tube through a fastener, and the main tube is connected with the connector.
