[0048] See also Figures 1 to 8The push-pull clamping assembly 2 includes a first base 21, a clamping assembly 22, a push-pull assembly 23, a second return member and a driving assembly 24. The first base 21 is used to be fixed on the magnetic fixing fixture 1; there are two clamping assemblies 22, and the two clamping assemblies 22 enclose a clamping cavity 2211. The clamping assembly 22 includes a clamping member 221 and a first return member. The clamping member 221 is slidably assembled on the first base 21 along the first direction.

The push-pull assembly 23 is between the two Between the clamping members 221, the push-pull assembly 23 is provided with a placement groove 2321 located in the clamping cavity 2211, and the placement groove 2321 is used to place the optoelectronic connection device 4; wherein, the clamping member 221 can push the push-pull assembly 23 to move in the direction away from the clamping cavity 2211; the second return member is respectively connected to the push-pull assembly 23 and the first base 21, and the second return member is used to provide a restoring force to drive the push-pull assembly 23 to move in the direction close to the clamping cavity 2211; the driving assembly 24 is arranged on the first base 21 and connected to the clamping member 221, and the driving assembly 24 is used to drive the clamping member 221 to move in the direction away from the clamping cavity 2211.

[0049] When the driving component 24 drives the clamping member 221 to move in the direction away from the clamping cavity 2211, the width of the clamping cavity 2211 increases; when the restoring force provided by the first restoring member drives the clamping member 221 to move in the direction close to the clamping cavity 2211, the width of the clamping cavity 2211 decreases, so that the driving component 24 and the push-pull component 23 can cooperate with each other to adjust the width of the clamping cavity 2211 to adapt to optoelectronic connectors 4 of different widths; the clamping member 221 can push the push-pull component 23 to move in the direction away from the clamping cavity 2211, and the restoring force provided by the second restoring component can The push-pull assembly 23 is driven to move toward the clamping cavity 2211, so that the placement groove 2321 can move in the clamping cavity 2211, that is, the push-pull assembly 23 can push the optoelectronic connector 4 to move in the clamping cavity 2211 to adapt to optoelectronic connectors 4 of different lengths, so that the fiber threading jig can adapt to optoelectronic connectors 4 of different sizes, and the fiber threading jig has better applicability; moreover, the clamping assembly 22, the push-pull assembly 23 and the driving assembly 24 can not only be modularly designed to reduce costs; they can also cooperate with each other to quickly clamp and disassemble the optoelectronic connector 4, effectively improving the fiber making efficiency.

[0050] It should be noted that the first direction and the second direction can be perpendicular to each other, or the angle between the first direction and the second direction can be set to an acute angle; the placement groove 2321 on the push-pull component 23 can match optoelectronic connecting devices 4 of different sizes, and the optoelectronic connecting devices 4 are clamped and fixed by the two clamping members 221 of the clamping component 22.

[0051] See also Figure 3 、 Figure 5 and Figure 6 In some embodiments, the placement groove 2321 can be a step groove, and a limiting protrusion 2213 is provided on the side of the clamping member 221 close to the clamping cavity 2211. The limiting protrusion 2213 cooperates with the inner wall of the step groove to clamp the front and back of the optoelectronic connection device 4.

[0053] See also Figure 3 、 Figure 5 and Figure 7 The abutting block 241 is provided with a first abutting inclined surface 2411 on both sides in the second direction, and the connecting seat 222 is provided with a second abutting inclined surface 22221 on the side close to the abutting block 241. The two first abutting inclined surfaces 2411 abut against the two second abutting inclined surfaces 22221 in a one-to-one correspondence. 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. When the abutting block 241 moves away from the clamping cavity 2211, the connecting seat 222 moves toward the clamping cavity 2211 under the action of the restoring force provided by the first restoring member, and the width of the clamping cavity 2211 decreases.

The end of the abutment block 241 away from the clamping cavity 2211 is provided with an abutment hole 2412. The first differential head partially extends into the abutment hole 2412. When the first differential head is rotated to the right, the first differential head extends outward and abuts the abutment block 241, and when the first differential head is rotated to the left, the first differential head retracts inward. Among them, when the first differential head is rotated to the right, the first differential head drives the abutment block 241 to move toward the direction close to the clamping cavity 2211, and the abutment block 241 pushes against the connecting seat 222 to move, and the clamping member 221 moves toward the direction close to the clamping cavity 2211 under the drive of the connecting seat 222, thereby increasing the width dimension of the clamping cavity 2211; when the first differential head is rotated to the left, the first differential head is separated from the abutment block 241, and the connecting seat 222 can move toward the direction close to the clamping cavity 2211 under the action of the restoring force provided by the first restoring member, and the width dimension of the clamping cavity 2211 is reduced.

[0058] See also Figure 4 、 Figure 5 and Figure 8 In some embodiments, a second avoidance groove 213 is further provided on the inner wall of the first mounting groove 211.

[0060] See also Figure 3 and Figure 6 The push-pull assembly 23 includes a push block 231 and a placement block 232. The push block 231 is slidably assembled on the first base 21 along the second direction; the placement block 232 is fixed to the side of the push block 231 away from the first base 21. The placement block 232 is provided with a placement groove 2321 on the side away from the first base 21.

The second slide 234 and the second guide rail 235 can be disposed between the two clamping members 221.

[0063] See also Figure 3 The push-pull assembly 23 further includes a second support base 233, which is fixed to the first base 21 and disposed at an end of the push-pull assembly 23 away from the clamping cavity 2211. A second restoring member is connected to the second support base 233 and the push-pull assembly 23, respectively, so that the second restoring member can provide a restoring force that drives the push-pull assembly 23 toward the clamping cavity 2211. The second restoring member can be a spring, as needed. The second support base 233 is disposed at an end of the push block 231 away from the clamping cavity 2211, and its two ends are connected to the push block 231 and the second support base 233, respectively.

[0064] See also Figure 1 、 Figure 9 and Figure 10 The magnetic fixing fixture 1 includes a second base 11 and a first magnetic component 12.

[0065] By providing the first magnetic assembly 12 on the second base 11, the magnetic fixture 1 can be fixed to the operating table by adsorption, preventing the fiber insertion device from moving during the fiber insertion process, thereby greatly improving the stability of the fiber insertion device. Moreover, compared with adhesive fixation, magnetic fixation does not leave glue residue on the bottom side of the second base 11, ensuring the flatness of the bottom side of the second base 11 and preventing the optical fiber end face and the horizontal plane of the optoelectronic connector 4 from tilting. In addition, because the first magnetic assembly 12 can switch between a magnetic state and a non-magnetic state, and can be adsorbed on the operating table in the magnetic state and detached from the operating table in the non-magnetic state, it is easy to disassemble and install.

[0066] See also Figure 9 and Figure 10In some embodiments, multiple first magnetic components 12 are provided, and the multiple first magnetic components 12 are spaced apart. Providing multiple first magnetic components 12 can improve the firmness of the second base 11 being adsorbed and fixed to the operating table. For example, two first magnetic components 12 are provided, and the two first magnetic components 12 are distributed at both ends of the second base 11. Depending on actual needs, three, four, five, etc. first magnetic components 12 can also be provided.

[0067] It should be understood that in other embodiments, there may be only one first magnetic component 12 , which is disposed in the middle of the second base 11 .
