[Previous technology]. According to the present, traditional tools in particular occupy a large number of export markets in the traditional industry-regardless of factors such as quality, practicability and good operability, those who have an advantage in the export market can seize the export market. Because of this, the innovation and improvement of functions and added value of hand tools are also the most important competitiveness of hand tools today, and the relative improvement of the appearance quality of hand tools is also a very important link. The handle structure of the known wrench is shown in the fourth figure. The process of this structure uses the semi-finished product after forging to directly perform surface treatment. However, this method will relatively increase the hardness of the structure during forging. It causes difficulties in subsequent processing. The general knowledge is mainly the use of sandblasting. After the processing is completed, mechanical processing is performed, such as: labeling, recessing in the handle and drilling, etc., and finally mirror polishing. Make the surface smoother, and continue to use electroplating to form an anti-corrosion treatment on the surface of the workpiece to complete the processing of the entire wrench. However, please refer to the fifth figure for the above structure. This kind of surface that is directly polished is liable to cause a rough surface at the corners and edges during the electroplating process. The rough surface of the corner edge (2) forms a major defect in the appearance of the body; on the other hand, in the conventional manufacturing process, because of the difficulty in surface treatment,
