Claim Text:
1. A manufacturing process of a foldable repairing tool bit comprising the following steps: (a) material preparing step: a stick with designated length is prepared; the stick has an embodying portion formed at one end thereof; the stick has a bending portion formed at another end thereof; (b) unnecessary material removing step: at least one side of the bending portion is removed via a cutting method to achieve a designated thickness of the bending portion so as to form a machining plane which has a smooth texture on a surface of the bending portion, the upper part of the bending portion of the stick is partially removed so as to form a machining plane, a connecting plane is formed between the machining plane and the embodying portion and a thickness of the connecting plane is reduced gradually from the embodying portion toward the bending portion; and (c) material bending step: the bending portion of the stick is bent so as to form a tool bit with a pivoting hole, the bending portion is bent to a bottom part of the bending portion which is opposite to the machining plane so that a terminal end of the bending portion corresponds to the bottom part of the bending portion.
