[0042] In one embodiment, the mounting base 1 is provided with a support plate 11, which supports the second part 9. The support plate 11 can support the second part 9, prevent the second part 9 from bending, and also save the operator's strength. The support plate 11 is provided with a first stop step 18 and a second stop step 19, which limit and stop the second part 9.

Then, the drive arm 12 is moved so that the first part 7 clamps the mounting part 21 and the second part 9 clamps the insertion part 22. Then, the terminal 20 welding device is moved above the heat source, and the heat source heats the mounting part 21 from bottom to top through the welding hole 5 to the set temperature, so that the welding piece melts. Then, the terminal 20 welding device is removed from the heat source, and the terminal 20 and the terminal 20 welding device are cooled. After the terminal 20 has cooled, the drive arm 12 is released, and the terminal 20 can be removed from the mounting base 1.
