[Prior Art] Press, the wrench tool uses the principle of lever to pull the screw-solid workpiece to achieve the effect of tightening or unscrewing, and it is necessary to assemble and combine the components of various industries by the screw firmware. Different types of screws need to be used, and different torques are applied to assemble and fix the fixed image. Heavy industry such as aviation, shipbuilding and passenger cars. Their components can be assembled with considerable strength to achieve a solid structure and withstand the impact of air pressure and power. In the precision industry, such as electronic machinery, the components cannot be assembled with excessive torque to ensure that they can be used accurately; no matter what kind of industrial products, less than one point of torque or more than one point of torque when combined with the screw It is very likely that the structure and the screw are ineffective or damaged, and the wrench tool is the key to controlling the torque. Whether the wrench tool can correctly and accurately reflect the value of the torque value has been the key point for the development of the industry. Related products have appeared, there are US Patent Case No. 3 9 7 〇 15 5, which is an electronic wrench, the structure includes the drive department The neck, the grip, and the strain gauge and display device are used to sense the torque and display the torque data; however, the electronic wrench is not designed to further consider the proportion of each part of the structure. Therefore, in the pulling operation, because the proportion of the wrench structure is not properly appropriate, the strain gauge can not accurately sense the pulling torque 100%, so the torque value data displayed by the display device and the wrench actually apply the screw firmware.

'When the wrench is to accurately and accurately reflect the torque of the pulling operation, in addition to the well-designed and sensitive strain gauge, the more important is the appropriateness of the proportion of the wrench structure; therefore, the structure of the conventional electronic torque tool The proportion is not properly appropriate, so the inventor of this case collected relevant information for evaluation and analysis. With many years of experience and research, the end of the test, the sensor structure that can help the strain gauge and other sensing devices to sense the torque value. [Explanation] The present invention provides an electronic torsion tool structure, in order to improve the conventional technology, which cannot accurately and accurately sense the lack of the torque value of the pulling operation. In order to achieve the foregoing object, the system of the present invention is provided with a driving portion at one end, and the driving portion can be a driving head of various types such as an opening, a plum or a D-head, and the other end of the body is provided with a grip portion for gripping the grip. A neck portion is disposed between the driving portion and the grip portion, and the body is further provided with a torque sensing member for sensing a pulling torque. The torque sensing member can be a strain gauge, a piezoelectric switch or the like. Sense ♦ device for measuring torque, and a display 7F control element for displaying the body and displaying the torque sensed by the torque sensing member, the display control unit includes a display screen, and a plurality of buttons, the body The torsion force in the pulling operation is sensed by the torsion sensing members on both sides of the neck, and is converted into specific data through the display screen; the body, the _ part, the neck, and the grip portion are provided with each other. Structure _, the ratio of the length of the neck to the neck is at least 7 · · i to the heart i; the ratio of the length of the grip to the neck is "5 · 1 to 6: 1; the grip and The width ratio of the neck is at least 14:5 to 6 1325807. * . 17: 5; the driver and the neck The degree ratio is at least 7:2 to g: 2, and the torque sensing member can accurately and accurately sense the pulling operation by appropriately fitting the structural ratio between the body, the driving portion, the neck portion and the grip portion. Torque force in the present invention; the structural ratio disclosed in the present invention is obtained through repeated experimental experiments. During the experiment, it is found that when the proportions of the various parts of the body structure are smaller than those proposed by the present invention, it is easy to cause the torque sensing member to actually apply the screw to the body. The torque sensing has some errors, and the proportions of the parts are larger than those proposed by the present invention, which may cause the strength of the body structure to be weakened. For example, the neck may be easily bent and even broken during the pulling operation. When the difference between the overall length of the conventional wrench and the length of the neck is small, the stress generated by the wrench is different if it is held at different positions; however, the design of the present invention can reduce the stress when held at different positions. The error is due to the fact that only when the parts are proportional to each other in the state proposed by the present invention, the structural strength and correct accuracy of the body can be considered. The actual torque. Therefore, the present invention is indeed a practical and progressive invention, and is worthy of industrial promotion and publicity to the public.
