However, when the optical fibers are rolled up on rollers, they are in an arc shape. When inserting the optical fibers into the couplers, workers are required to manually insert the optical fibers into the couplers. Since the optical fibers are relatively soft and difficult to connect, the work efficiency is low. Summary of the invention

At the same time, it also avoids the problem that most of the optical fibers 7 are soft wire connectors and are difficult to fix during coupling. Then, during the process of the sliding block 12 moving to contact 26, the sliding block 12 causes the fourth wedge block 26 to move downward, and then, under the elastic force of the fourth spring 25, 24 and the sliding block 12 are pushed to move to the right side of the groove of the guide frame 3 (such as Figure 5 As shown), the sliding block 12 is restored to its initial position through the groove on the outer side of the guide frame 3.

[0038] Step 1: Pass the optical fiber 7 to be coupled through the through hole opened in the fixing plate 11;

[0039] Step 2: Clamp the optical fiber 7 with the clamping block 14, start the driving device, and insert the optical fiber 7 into the coupling member 2.

[0040] Step 3: Start the driving device and insert the optical fiber 7 into the coupling element 2.

[0041] Working principle: pass the optical fiber 7 through the through hole opened on the fixing plate 11; clamp it with the link 14, then start the first motor 8 to drive the threaded rod 10 to rotate, and the threaded rod 10 drives the slide plate 18 to move downward after the rotation of the threaded rod 10, and the slide plate 18 drives the sliding block 12 to move downward on the groove on the inner side of the guide frame 3, and then when the sliding block 12 moves to contact with the third wedge block 22, the sliding block 12 drives the third wedge block 22 to move downward, and the third wedge block 22 moves the push block 24 to the left by pulling the second traction rope 23 (such as Figure 5 Then the push block 24 drives the inclined surface of the fourth wedge block 26 to make the fourth wedge block 26 move downward to cancel the obstruction of the push block 24. After the push block 24 leaves the inclined surface of the fourth wedge block 26, the fourth wedge block 26 returns to its initial position under the elastic force of the fifth spring 27 to limit 24 until the third wedge block 22 moves down to the lowest end. The inclined surface of the sliding block 12 drives the third wedge block 22 to squeeze the sixth spring 28 into the groove where the sixth spring 28 is located. Then the sliding block 12 continues to move downward and leaves the inclined surface of the third wedge block 22.
