Description of the Invention: [Technical Field] The present invention relates to a data identification technique for tool force application, and more particularly to a hand tool torque indicating device. g [Prior Art] In Fig. 1, a wrench 1 is disclosed in U.S. Patent No. 7,631,583 (similar to Taiwan No. 1324547), the composition comprising a driving portion 1, a handle portion 2 and a grip The holding portion 3, wherein the driving portion 1 is connected to the first end 4 of the hollow body portion 2, and performs a locking operation on the sleeve or the workpiece, and the grip portion 3 and the second portion of the handle portion 2 The ends 5 are secured together to facilitate the user's grip. Three dials 6 are mounted on the handle body 2 adjacent to the grip portion 3. These turntables 6 are arranged side by side and can be manually rotated. The disc faces are arranged in a plurality of scales 7, and the index 8 of the grip body portion 2 and the grip portion 3 are fixed. Determine the torque value output by the wrench 100. However, the adjustment mode of the turntable 6 is not only complicated, but the adjusted torque value cannot judge the accuracy. On the contrary, it is obviously not convenient to compare the strain value of the driving portion 1 which is developed by the electronic display unit 9. Moreover, the increase of the turntable 6 and the electronic display unit 9 also increases the burden of production costs, which is not conducive to market marketing. . Secondly, the electronic display unit has been exposed by patents such as US No. 7, No. 7, No. 7,884, No. 7, 37, 539, and Taiwan No. 1316889, although it can display a precise twist value of 'but 疋The value of the screen display is only for individual units, such as the metric unit Nm (Newton·m). If you want other unit data, such as English 201223715 lb_ft (@〇 or kg_m (kg·m) units, you must press the button] Through calculation, it can be converted into the required unit data and read at the same time. What's more, 'electronic screens and buttons are exposed to the periphery, which is not only easy to be affected by the tide recording #, causing poor touch defects, ', will change the output torque due to accidental touch The setting value causes the operation to be made. Alternatively, the display unit can also be mechanical. For the construction, please refer to 矣: Country No. 2'205, 510 '7, 〇44, 〇36, D257, 626, Bay No. _7 In the patent case, a scale is placed around the surface of the hollow handle body, and an inner rod is assembled in the handle. The outer rod is engraved with a whole row of engravings along the length direction, and the inner rod is opposite to the shaft of the handle body ^ Exercise, visually interpret the torque value. The scales are close to the numbers, which are quite dense with each other, which hinders the data interpretation. In particular, the single digits or the values after the decimal point are more difficult to recognize, and the probability of false positives is increased during the data comparison period of the two units. In view of this, the inventor goes deep. Exploring the problems of the prior art, and actively pursuing solutions through years of experience in R&D and manufacturing of related industries, and finally successfully developed a torque indicating device suitable for hand tools to improve the problems of the conventional invention. The purpose of the invention is to adopt the function of different gear ratios to achieve the function of the predetermined speed ratio, and can realize different unit quantities at the same time without formula conversion, and easily understand the current torque value, which is convenient to use. The hand tool torque indicating device of the present invention is applied to a hollow hand tool, including: 201223715 a positioning plate, positioned inside the hand tool; two toothed rings 'side side by side, in the 夂-^~ in each tooth The circumferential surface rod does not have some numbers, the inner circumferential surface forms the inner ring tooth surface; the door (five) rim side; the bottom cover, Fit the positioning disc to seal the inner ring tooth surface of the two toothed ring
