When popping out, the elastically arranged second abutting rod 40 is extruded from the abutting groove 38. The gas inside the second airbag 41 on one side of the second abutting rod 40 is discharged to the first airbag 35 through the exhaust pipe 37. The first airbag 35 expands to push the third limiting rod 34 to be inserted into one group of the fixing grooves 7, completing the fixation of the adjusting plate 5 and the guide rod 4, and further fixing the height of the optical fiber transceiver port.

[0061] Specifically, as Figure 3and Figures 5-6 As shown, the lower end of the first insertion rod 11 is provided with two groups of symmetrically distributed clearance grooves 17, and the interior of each of the clearance grooves 17 is hinged with a first abutting rod 18;

[0062] A fixing assembly is disposed inside the first insertion rod 11 for fixing the hinged first abutting rod 18;

[0063] The fixing assembly includes a second limiting groove 26 formed at the end of the first abutting rod 18;

[0064] A through slot 27 is formed inside the first insertion rod 11 at a position corresponding to the second limiting slot 26, a second limiting rod 28 is disposed inside the through slot 27, and a guide block 30 is installed on the side wall of the second limiting rod 28, a guide slot 29 is formed on the side wall of the through slot 27 at a position corresponding to the guide block 30, the guide block 30 is slidably disposed inside the guide slot 29, and a fifth return spring 31 is disposed between the side wall of the guide block 30 and the inner wall of the guide slot 29;

[0071] In this embodiment: When the first insertion rod 11 pops out, the trigger rod 20 at the end of the first insertion rod 11 is squeezed. When the trigger rod 20 is displaced, the first inclined slot 22 moves relative to the second insertion rod 24. At this time, the second insertion rod 24 moves upward under the action of the fourth return spring 25. When the second insertion rod 24 moves upward, the second inclined slot 32 moves upward relative to the second limiting rod 28. At this time, the second limiting rod 28 moves horizontally relative to the first abutting rod 18 under the action of the fifth return spring 31. After the first abutting rod 18 hinged to the first insertion rod 11 is released from the limit, it rotates. At this time, the end of the first abutting rod 18 contacts the upper end of the fiber optic transceiver port and abuts downward against the fiber optic transceiver port, so that the fiber optic transceiver port is limited inside the limit frame 2, and it can better make the pins of the fiber optic transceiver port contact the tin liquid and the test circuit board.

[0072] The specific solution of this scheme is: Place the fiber optic transceiver port inside the limit frame 2.

At this time, the first insertion rod 11 pops out under the action of the first return spring 12 and is inserted into the inside of the slot 9. When popping out, the elastically arranged second abutting rod 40 is extruded from the abutting slot 38. The gas inside the second airbag 41 on one side of the second abutting rod 40 is discharged to the first airbag 35 through the exhaust pipeline 37. The first airbag 35 expands and pushes the third limiting rod 34 to be inserted into one group of fixing slots 7, completing the fixation of the adjusting plate 5 and the guiding rod 4;

[0073] When the first insertion rod 11 pops out, the trigger rod 20 at the end of the first insertion rod 11 is squeezed. When the trigger rod 20 is displaced, the first inclined slot 22 moves relative to the second insertion rod 24. At this time, the second insertion rod 24 moves upward under the action of the fourth return spring 25. When the second insertion rod 24 moves upward, the second inclined slot 32 moves upward relative to the second limiting rod 28. At this time, the second limiting rod 28 moves horizontally relative to the first abutting rod 18 under the action of the fifth return spring 31. After the first abutting rod 18 hinged to the first insertion rod 11 is released from the limit, it rotates. At this time, the end of the first abutting rod 18 contacts the upper end of the fiber optic transceiver port and abuts downward against the fiber optic transceiver port, so that the fiber optic transceiver port is limited inside the limit frame 2;

[0074] Then place the tinning and fixing device above the tin furnace, and insert the pins of the fiber optic transceiver port into the tin liquid to complete the tinning.
