[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0022] Example: See also Figure 1 and Figure 2 The embodiment of the present invention provides a fiber threading device, including a magnetic fixing fixture 1, a push-pull clamping assembly 2 and a cable fixing fixture 3. The magnetic fixing fixture 1 is used for adsorption and fixing on the operating table; the cable fixing fixture 3 is arranged on the magnetic fixing fixture 1, and the cable fixing fixture 3 is provided with a wire-passing channel 3211 for placing cables; the push-pull clamping assembly 2 is arranged on the magnetic fixing fixture 1, and the push-pull clamping assembly 2 is provided with a placement groove 2321 for placing the optoelectronic connection device 4; wherein, the cable fixing fixture 3 and the push-pull clamping assembly 2 are respectively arranged at two ends of the magnetic fixing fixture 1, and the wire-passing channel 3211 and the placement groove 2321 are coaxially arranged.

[0023] By fixing the cable fixing fixture 3 and the push-pull clamping assembly 2 on the magnetic fixing fixture 1, the magnetic fixing fixture 1 is adsorbed and fixed on the operating table, so that there is no need to glue the cable fixing fixture 3 and the push-pull clamping assembly 2 to 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.

[0024] See also Figures 1 to 4The magnetic fixing fixture 1 includes a first base 11 and a first magnetic component 12. The first base 11 has a bottom side and a top side that are relatively distributed, and the push-pull clamping component 2 and the cable fixing fixture 3 are fixed to the top side of the first base 11; the first magnetic component 12 is arranged on the bottom side of the first base 11, and the first magnetic component 12 is provided with a switchable magnetic state and a non-magnetic state; wherein, when the first magnetic component 12 is in a magnetic state, the first magnetic component 12 can be adsorbed on the operating table; when the first magnetic component 12 is in a non-magnetic state, the first magnetic component 12 can be detached from the operating table.

[0025] By setting the first magnetic component 12 on the first base 11, the magnetic fixing fixture 1 can be adsorbed and fixed on the operating table to prevent the fiber insertion device from moving during the fiber insertion process, thereby greatly improving the stability of the fiber insertion device. Moreover, compared with the glue point adhesive fixation, the magnetic fixation will not leave glue residue on the bottom side of the first base 11, ensuring the flatness of the bottom side of the first base 11 and avoiding the inclination angle between the optical fiber end face and the horizontal plane of the optoelectronic connection device 4. In addition, since the first magnetic component 12 can be switched between the magnetic state and the non-magnetic state, and can be adsorbed on the operating table when in the magnetic state, and can be detached from the operating table when in the non-magnetic state, it is easy to disassemble and install.

[0026] See also Figure 3 and Figure 4 In some embodiments, a plurality of first magnetic components 12 are provided, and the plurality of first magnetic components 12 are distributed at intervals. The plurality of first magnetic components 12 can improve the firmness of the first base 11 being adsorbed and fixed on the operating table.

According to actual needs, three, four, five, etc. first magnetic components 12 can also be provided.

[0027] It should be understood that in some other embodiments, only one first magnetic attraction component 12 may be provided, and the first magnetic attraction component 12 is disposed in the middle of the first base 11 .

[0028] See also Figure 3 and Figure 4, the first magnetic attraction component 12 includes an adsorption seat 121, a magnet and a knob 122.

Among them, when the knob 122 is in the first position, the first magnetic pole is in contact with the first soft magnet, and the second magnetic pole is in contact with the second soft magnet. At this time, the first soft magnet and the second soft magnet can be magnetized by the magnetic steel and have magnetism, so that the adsorption seat 121 is in a magnetic state, and the adsorption seat 121 can be adsorbed and fixed on the operating table; when the knob 122 is in the second position, the first magnetic pole and the second magnetic pole are both in contact with the first soft magnet and the second soft magnet. At this time, the first soft magnet and the second soft magnet cannot be magnetized by the magnetic steel, so that the adsorption seat 121 is in a non-magnetic state, and the adsorption seat 121 can be detached from the operating table.

[0029] According to actual needs, the first magnetic pole can be an N pole, and the second magnetic pole can be an S pole; a brass block is arranged between the first soft magnet and the second soft magnet, that is, the first soft magnet and the second soft magnet are separated by the brass block, and the inner walls of the first soft magnet and the second soft magnet can be provided with electrical soft iron. Wherein, when the knob 122 is in the first position, the first magnetic pole only contacts the electrical soft iron on the first soft magnet, and the second magnetic pole only contacts the electrical soft iron on the second soft magnet. At this time, the first soft magnet and the second soft magnet are independent components, so that the first soft magnet and the second soft magnet can be magnetized by the magnetic steel; when the knob 122 is in the second position, the first magnetic pole contacts the brass block, and the second magnetic pole also contacts the brass block. At this time, the first soft magnet and the second soft magnet are connected as a whole by the magnetic steel, so that the first soft magnet and the second soft magnet cannot be magnetized by the magnetic steel.

[0030] It should be understood that when the first magnetic component 12 includes an adsorption seat 121, a magnetic steel, a knob 122, a brass block and an electrical soft iron, the first magnetic component 12 can be a switch magnetic seat.

[0034] It should be understood that the overall height of the push-pull clamping assembly 2 is smaller than the overall height of the cable fixing fixture 3. Setting the top side surface of the first fixing part 111 to be raised relative to the top side surface of the second fixing part 112 can ensure that the cable and the optoelectronic connection device 4 are at the same height when the fiber is inserted.
