A soldering iron with two uses
One main machine, double soldering iron, easy to use!
Avoid the damage of the iron head caused by frequent working procedures!
This expander can be extended to use two different soldering head type handles with one soldering iron main engine.
It can be picked up and used when different requirements are met in maintenance, and the expander does not occupy space.
Maintenance technicians usually use I (sharp head ) and K (knife head) as soldering iron heads.
Different needs require maintenance technicians to replace soldering iron heads for different use needs, but this will also speed up the loss of soldering iron heads and handles.
