Problems solved by technology

[0002] The screws for installing and fixing metal parts are easy to break due to improper installation or long-term rust when the screws are removed, but it is not easy to remove the broken screws inside the metal parts. Generally, electric welding is used to weld the broken nails to another nut. Screw the nut to take out the broken nail. This method requires the help of an electric welding machine and has limitations.
Or use direct hammering to destroy the broken nail, so as to take out the broken nail. This method is likely to damage the metal parts connected to it. At present, there is no special tool for taking out the broken nail on the market.
