[Prior Art] When the existing digital torque tool is used to measure the torque, most of the strain gauges, such as strain gauges, are combined with the tool body to make the hand tool deform when the handle is deformed and the handle body is deformed. The resistance change occurs with the deformation of the handle body. ## By measuring the change of the resistance, it can be converted into the torque of the hand tool, thereby achieving the function of displaying or warning the torque value. However, in the manufacturing process of the existing 9-digit torque hand tool, the raw material steel is often subjected to different heat treatments for different hand tools of 1 Τ U, which results in different hardness of the hand tool and various types. The thickness of the material of the hand tool is also different, and it is difficult to control the change of the temperature difference between the manual and the use of the 裱 、 ' 此 此 此 此 此 此 此 此 此 此 此 此 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手 手error. Because the existing digital torque hand tools are accurate, there are still some shortcomings in the early accuracy. Therefore, they have become the tools of ordinary users for daily use or DIY, and they are not suitable for professional use. The same accuracy tool 'also leads to a limited range of applications available to existing King's digital torque tools.

Preferably, one side of the pivotal end of the handle section is convexly provided with a planting piece, and the pivoting piece is pivotally disposed on the first pivot of the head section, and the other of the pivoting ends corresponds to The head section is provided with one side of the second pivot, and the end surface of the side is concave: a receiving groove is formed. The hydraulic cylinder and the pressure sensor are fixed in the receiving groove. The torque conversion display and the battery system are disposed on the handle M326874. The end surface of the joint end of the head section is inclined with respect to the direction in which the head section extends, and the end surface of the pivot end of the handle section extends relative to the handle section. The direction is inclined. The specific effects that can be achieved in this creation include ···························································································· And the characteristics of the (4), = two and the high temperature accuracy of the change in the temperature of the soil. . Therefore, the twisting force measurement of this creation has 2. Because the creation can be carried out high, but it can be applied to the torque measurement of the general use of ..., so it is not applicable to the field, and even if it is needed, it is more suitable for professional places. The range of test applications to be extremely 'accurate' can also be possessed.
