The using method of the device is convenient, the operation is simple, the broken nail can be removed easily just by using a simple tool, and time and labor are thus saved; the device is suitable for connecting screws of any metal part and avoids damage to the connected metal part; and a blank in the field of hardware tools is filled.

Description

technical field [0001] The invention relates to a broken nail remover, which relates to a hardware tool, in particular to a hand tool which can easily take out broken nails. Background technique [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 beating to destroy the broken nail, so as to take out the broken nail. This method is likely to destroy the metal parts connected by it. At present, there is no tool specially used for taking out the broken nail on the market. Contents of the invention [0003] The present invention overcomes the shortcomings of the prior art, and the technical probl...
