[0057] Example:

[0058] See also Figure 1 and Figure 2 The present invention provides a fiber threading device, including a magnetic fixture 1, a push-pull clamping assembly 2, and a cable fixture 3. The magnetic fixture 1 is used to be fixed on an operating table by adsorption; the cable fixture 3 is arranged on the magnetic fixture 1, and the cable fixture 3 is provided with a wire channel 3211 for placing cables; the push-pull clamping assembly 2 is arranged on the magnetic fixture 1, and the push-pull clamping assembly 2 is provided with a placement groove 2321 for placing an optoelectronic connector 4; wherein, the cable fixture 3 and the push-pull clamping assembly 2 are respectively arranged at both ends of the magnetic fixture 1, and the wire channel 3211 and the placement groove 2321 are coaxially arranged.

[0059] By fixing the cable fixing jig 3 and the push-pull clamping assembly 2 on the magnetic fixing jig 1, the magnetic fixing jig 1 is adsorbed and fixed on the operating table, so that there is no need to glue the cable fixing jig 3 and the push-pull clamping assembly 2 on the operating table separately, and the fixing operation method is simpler; moreover, compared with glue fixation, magnetic fixation is more convenient to disassemble and install.

[0060] See also Figures 1 to 4The cable fixing fixture 3 includes a displacement adjustment platform 31 and a fixed shell 32. The displacement adjustment platform 31 includes a first displacement adjustment component 311 and a second displacement adjustment component 312. The first displacement adjustment component 311 is fixed to the magnetic fixing fixture 1, and the second displacement adjustment component 312 is fixed to the first displacement adjustment component 311; the fixed shell 32 is fixed to the second displacement adjustment component 312, and the fixed shell 32 is provided with a wire passage 3211; wherein the first displacement adjustment component 311 is used to drive the second displacement adjustment component 312 to move in a first direction, and the second displacement adjustment component 312 is used to drive the fixed shell 32 to move in a second direction, and the first direction is perpendicular to the second direction.

[0061] One of the first direction and the second direction can be the X direction, and the other can be the Y direction, so that the displacement adjustment platform 31 is an XY adjustment platform. The XY adjustment platform can be used to adjust the position of the fixed shell 32, thereby changing the position of the cable in the wire channel 3211 relative to the optoelectronic connection device 4. The adjustment method is simple and easy to operate. Moreover, it can improve the position accuracy of the optical fiber at the front end of the cable during the fiber insertion and fixing process, reduce the alignment error during the fiber insertion process, and make the fiber insertion quality higher and the effect better.

[0062] See also Figure 3 and Figure 4 The fixed housing 32 includes a bottom housing 321, an upper cover 322, and a first locking assembly 323. The bottom housing 321 is mounted on the second displacement adjustment assembly 312 and is provided with a wire passage 3211.

The first locking assembly 323 has a locked state in which the upper cover 322 and the bottom housing 321 are fixed to each other, and an unlocked state in which the upper cover 322 and the bottom housing 321 are separated. When the first locking assembly 323 is in the unlocked state and the upper cover 322 is rotated to the open opening, the cable is placed into the wire channel 3211 through the opening, and the placement method is simple; when the upper cover 322 is rotated to the closed opening and the first locking assembly 323 is in the locked state, the upper cover 322 and the bottom shell 321 jointly confine the cable in the wire channel 3211, thereby fixing the cable, avoiding position deviation during optical fiber alignment, and improving the accuracy of optical fiber alignment.

[0063] It should be noted that when the cable is placed in the wire channel 3211, at least part of the cable is raised on the surface of the side with an opening relative to the bottom shell 321, so that when the upper cover 322 is rotated to close the opening, the upper cover 322 will squeeze the cable to avoid fiber debonding during glue curing and ensure that the optical fiber end face is flush.

[0064] See also Figure 3 and Figure 4 In some embodiments, the first locking assembly 323 includes a first adsorption member 3231 and a second adsorption member 3232. The first adsorption member 3231 is disposed on a side of the upper cover 322 close to the bottom shell 321; the second adsorption member 3232 is disposed on a side of the bottom shell 321 close to the upper cover 322; wherein the first adsorption member 3231 and the second adsorption member 3232 are both magnets; or, one of the first adsorption member 3231 and the second adsorption member 3232 is a magnet and the other is a magnetic member, so that the locking method of the first locking assembly 323 is magnetic adsorption locking and fixing.

At this time, the first soft magnet and the second soft magnet are connected into one by the magnetic steel, so that the first soft magnet and the second soft magnet cannot be magnetized by the magnetic steel.

When the abutting block 241 moves toward the clamping cavity 2211, the first abutting inclined surfaces 2411 abut against the second abutting inclined surfaces 22221, causing the connecting seat 222 to move away from the clamping cavity 2211. Driven by the connecting seat 222, the clamping member 221 moves away from the clamping cavity 2211, and the width of the clamping cavity 2211 increases.
