Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an improvement of a torsion force measurement tool, especially a hand tool measurement device with high accuracy torsion force measurement and low cost. [Previous technology] According to the current situation, the machine tool mother machine is able to win the domestic and foreign sales markets. Therefore, the tolerance of the structural components of the machine tool mother machine, and even the size of the screw force between the structural components is also the focus of the quality requirements of various manufacturers. Where it is obvious, the traditional wrench tools such as screw nuts, bolts and other screw components are not enough for consumers. Therefore, in order to accurately control the screwing force of the screwing element, the industry has developed a wrench tool with a torque measurement function to respond to it. Among them, refer to Annex I (Taiwan Patent Bulletin No. 4 9 6 2 5 2 "Fine Adjustment Torque wrench structure "), it is not difficult to see from the first picture in Annex I that this type of torque measuring wrench mainly uses the scale set on the handle of the wrench, and then cooperates with the measuring rod in a linkage relationship with the driving head of the wrench. When the user rotates the driving head, the displacement of the measuring rod can be used to achieve the effect of rotational torque notification. Attachment 2 (Taiwan Patent Bulletin No. 5 0 3 1 6 2 "torque wrench"), attachment The structure of the open-end torque wrench shown in the first figure is very different from that of the socket wrench body in attachment 1. For this reason, _ the industry changed to embed the spring and roller in the handle of the open-end wrench Inside, measure the effect with the torque. However, the above-mentioned Annexes 1 and 2 use traditional structural elements as torsional force measurement devices for manual tools. As a whole, there is a problem of complicated structure of the torsional force measurement devices. At the same time, the complexity of the structural components that should be used further develops.

After f is converted by the converter, the voltage signals can be converted into digital signals known by the public, and finally through the display device on the handle. You can know the numerical effect of the torque of the plate movement. This kind of strain gauge through the bridge circuit has a better torque sensing effect, but the unit price of the strain gauge is It is one of the factors that cause the product to be delayed. The job is ‘how to make the measuring device of torque wrench conform to high precision measurement’ and the torque measuring device which has both the low cost and the high cost of structure. This is an urgent problem for the industry. [Summary of the invention] The present invention provides a torque measuring hand tool with both low-cost and high-precision measurement values. The piezoelectric ceramic is mainly subjected to external force to generate a polarization phenomenon, so that positive and negative charges are generated on the surface edges of the piezoelectric ceramic. (The so-called piezoelectric effect), and then the voltage signal is transmitted to the display device on the handle through the conductive body connected to the two ends of the piezoelectric ceramic, and the voltage signal is converted into digital by the converter in the display device. The signal, in turn, accurately informs the user of the magnitude and effectiveness of the torque. '' By using piezoelectric ceramics that are easy to manufacture, low cost, and highly sensitive and accurate, as a torque sensing device for hand tools, not only can it be greatly reduced
