Method of manufacturing a tool bit of a foldable repairing tool set

Abstract

A manufacturing method of a tool bit of a foldable repairing tool set includes a material preparing step, an unnecessary material removing step and a material bending step. Wherein, a stick with a designated length is prepared firstly, where one end of the stick is a bending portion, and another end of the stick is an embodying portion; and then, at least one side of the bending portion is partially removed so as to form a smooth surface thereof; finally, the bending portion are bent so as to form a tool bit with a pivoting hole. Under this arrangement, said tool bits are pivotally assembled in a tool base so as to form a foldable repairing tool set.

What is claimed is: 
     
         1 . A method of manufacturing a tool bit of a foldable repairing tool set, 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; and   (c) material bending step: the bending portion of the stick is bent so as to form a tool bit with a pivoting hole;   wherein in step (b), the bottom part of the bending portion of the stick is partially removed so as to form a sub machining plane; a sub connecting plane is formed between the sub machining plane and the embodying portion; a thickness of the sub connecting plane is reduced gradually from the embodying portion toward the bending portion; and in step (c), the bending portion is bent to the sub machining plane so that the terminal end of the bending portion corresponds to the sub machining plane.   
     
     
         2 . The method as claimed in  claim 1 , further comprising:
 (d) a second unnecessary material removing step: the second unnecessary material removing step is proceeded after the material bending step is finished; wherein an outer part of the bending portion is partially removed so as to form an inferior machining plane; an inferior connecting plane is formed between the inferior machining plane and the embodying portion; a inferior thickness of the inferior connecting plane is reduced gradually from the embodying portion of the stick toward the bending portion of the stick.
