[0002] When manually soldering a PCB board, a corresponding soldering device is required. The traditional PCB board plug-in soldering process is as follows: Insert the plug from the back at the corresponding soldering position on the PCB board, and then place it horizontally on the workbench; then place the soldering iron head at the junction of the lead pad, and heat the pad and the lead simultaneously. Put in the solder wire, and after soldering is completed, withdraw the solder wire and the soldering iron. A large amount of smoke will be generated during soldering with the traditional soldering device.

[0003] The prior art CN209189967U discloses an electric soldering iron device for manually soldering PCB board plugs, including a base, a housing, and a wire.
