[0026] Please refer to Figures 3-5 , a T-shaped block 10 is fixedly installed at the bottom of the active block 4, a sliding groove is opened inside the base 1, and the T-shaped block 10 is slidably connected to the inside of the sliding groove.

The placement groove can store the bottom of the limiting block 12, and the limiting block 12 and the reinforcing block 11 improve the stability of the welding jig when adjusting the positions of multiple active blocks 4, prevent multiple active blocks 4 from generating different movement paths, reduce the workload of the staff, and improve the working efficiency of the welding jig.
[0027] Embodiment 2
[0028] Please refer to Figure 3 And Figure 6, baffles 13 are installed on both sides of the outer surface of the support frame 2, and a placement cylinder 14 is arranged inside the support frame 2. Connecting blocks 15 are fixedly installed on both sides of the outer surface of the placement cylinder 14, and pins are slidably connected inside the placement cylinder 14. A moving groove is formed on the outer surface of the support frame 2, and the connecting block 15 is slidably connected to the inside of the moving groove. The moving groove facilitates limiting the moving path of the connecting block 15. A rack 16 is fixedly installed on one side of the outer surface of the connecting block 15. A gear 17 is rotatably connected to the outer surface of the rack 16, and the gear 17 meshes with the rack 16. The rack 16 facilitates driving the connecting block 15 to move. A fixing rod 18 is rotatably connected to the outer surfaces of the support frame 2 and the baffle 13, and the gear 17 is fixedly installed on the outer surface of the fixing rod 18. A turning handle 19 is fixedly installed at one end of the outer surface of the fixing rod 18. By rotating the turning handle 19, the fixing rod 18 can be driven to rotate, and the rotation of the gear 17 can drive the two connecting blocks 15 to gather or disperse. While the welding jig stably supports the pins, the distance between them can be adjusted, increasing the applicable range of the welding jig.
[0029] Working principle: During the use of the welding jig, first, the pull handle 6 is used to drive the connecting plate 5 to move inside the groove, and the limit block 12 is pulled away from the limit groove. Then, the connecting plate 5 drives the movable block 4 to move, and the reinforcing block 11 makes the connection between the movable block 4 and the connecting plate 5 more stable. During the movement of the movable block 4, its movement path can be limited by the T-shaped block 10 and the sliding groove. Then, the movable block 4 drives the spring 9 to be compressed inside the receiving groove 8. Subsequently, the limit block 12 can be released to insert it into the limit groove, thereby completing the limitation of the connecting plate 5, and the pull handle 6 is released. Then, the microphone head is placed between the buffer pad 3 and the movable block 4, and the rubber materials of the buffer pad 3 and the movable block 4 can prevent the microphone head from being pinched and damaged. Then, the limit block 12 is pulled, and the reset of the spring 9 drives the connecting plate 5 and the movable block 4 to move, so that the movable block 4 clamps the microphone head. Subsequently, the limit block 12 is released, and the limitation of the connecting plate 5 is completed by inserting the limit block 12 into the limit groove, which improves the stability of the welding jig when adjusting the positions of multiple movable blocks 4, prevents multiple movable blocks 4 from generating different movement paths, reduces the workload of the staff, and improves the working efficiency of the welding jig. Then, the rotary handle 19 drives the fixed rod 18 to rotate on the support frame 2 and the baffle 13, and the fixed rod 18 drives the gear 17 to rotate. Then, the gear 17 drives the rack 16 to move. Subsequently, the rack 16 drives the connecting block 15 to move inside the moving groove, and the connecting block 15 drives the placing cylinder 14 to move. Since the racks 16 on the two connecting blocks 15 share a set of gears 17, the rotation of the gear 17 can drive the two connecting blocks 15 to gather or disperse, thereby completing the adjustment of the distance between the placing cylinders 14, enabling the welding jig to stably support the pins while adjusting their distances, increasing the applicable range of the welding jig. Then, the pins are placed in the placing cylinders 14, and the pins can be welded to the circuit board at the top of the microphone head through the welding device.
