[0034] like Figure 4 - Figure 5 As shown, the protective cylinder 21 includes two arc plates 211. The two arc plates 211 can form a cylinder. The two arc plates 211 penetrate through and are movably connected to the front of the outer shell 1. The rear end of the arc plates 211 is fixedly connected to a limiting strip 212. The two limiting strips 212 can form a ring, which is used to limit the protective cylinder 21 and prevent the protective cylinder 21 from detaching from the outer shell 1. Rubber pads 213 are fixedly connected to the inner side of the two arc plates 211 to protect the optical fiber. The front of the outer wall of the two arc plates 211 is provided with a limiting groove 214, which is used to connect with the rubber ring 23. The two limiting grooves 214 can form a ring groove. The rubber ring 23 is movably connected to the limiting groove 214.

[0035] Further, the fixing assembly 22 comprises a fixing ring 221, which is used for matched connection of components and matched cooperation with the limiting strips 212 to match the positioning of the protection cylinder 21. The fixing ring 221 is sleeved on the outside of the two arc plates 211. The front side of the fixing ring 221 is fixedly connected with a connecting ring 222, which is used for matched connection of the control sleeve 225. The front side of the connecting ring 222 is fixedly connected with a plurality of limiting petals 223, which can be deformed to a certain extent. The inside of the limiting petals 223 is provided with a protrusion. The front end of the outer wall of the protrusion is provided as an inclined arc surface.

Then the protection cylinder 21 is sleeved on the outside of the optical fiber body 3. The two arc plates 211 are fixed on the upper and lower sides of the optical fiber body 3 respectively. Then the arc plates 211 are passed through the hole on the shell 1. The limiting strips 212 on the rear part of the arc plates are abutted against the inner side of the shell 1. Then the fixing ring 221 is sleeved on the outside of the two arc plates 211 together with the connecting ring 222 and the plurality of limiting petals 223. The fixing ring 221 is abutted against the outer side of the shell 1. Then the control sleeve 225 is screwed with the connecting ring 222. Thus the control groove 226 controls the plurality of limiting petals 223 to shrink. The plurality of limiting petals 223 fix the two arc plates 211. Then the rubber ring 23 is sleeved on the outside of the two arc plates 211. The rubber ring 23 is clamped in the limiting groove 214. Then the optical fiber body 3 is cut to a proper length. A connector is installed on the cut end of the optical fiber body 3. According to the distribution of the optical fiber, the positioning assembly 5 is fixed at a proper position in the shell 1. During fixing of the positioning assembly 5, the sticking piece 52 on the lower part of the positioning assembly 5 is pasted and fixed in the shell 1. Then the optical fiber cable is clamped in the clamping ring 53 on the upper part of the base 51.
