Description of the Invention: [Technical Field of the Invention] The present invention relates to a "torque force measuring mechanism for a hand tool", and more particularly to a wrench tool capable of accurately measuring a torque value. [Prior Art] According to the current public, the D Iγ is popular in the home, and the domestic hand tools development system is quite mature and stable. Among them, regardless of product type or structural quality, it has won the country (10). In the past few years, in order to make the general public, the masses in the production of the industry have become more and more popular, so the hand tools of the county in operation or with humanized functions have also been asked. The pain can be matched with the AIDS, the principle of the single force 1 (four) the object combined 'and the object can be combined and can be repeatedly removed, so it can be applied to all kinds of different sizes' and the torque tool is the largest when operating The problem is that the user is not easy to pinch out the freshness of the piece, meaning that the user can not know the tightness of the situation, 'only guessing whether the screw is fastened by the sixth sense of its own, and the tightness of the screw is tight. When it is insufficient, it can't achieve the effect of screwing two objects, and it is easy to loosen. On the contrary, when the tightness of the screw is too high, the screw is easy to collapse, and the object is easily damaged and deformed. 1=The situation cannot be disassembled, especially In precision shavings or small instruments, because of the = more than a (a) a, the material (four) side of the side of the noise is more than a test 于此 41 here 'each of the torque tool manufacturers have introduced a twisted force two pull 11 tools' such as the US patent No. 3 9 7 0 1 5 5, which is a "hand tool and a two-gauge gauge between the grip and the pull head, 5 1252795 • The strained hand is pure hand _ (four) set to enable the torsion of the object The size of the value, and show the Zen ^ = on the test The accuracy of the above-mentioned twisting force measuring structure is still insufficient. The value of the wheat=force is for the user's reference, but the precision axis=the whole (four). The discussion is quite realistic and necessary to be improved. SUMMARY OF THE INVENTION The hair braiding and tenderness-(four)^_measuring mechanism can improve the self-hand tool without the torque measurement effect, or the measurement data is inaccurate. For the purpose of the Dao Weng (4), the hair _ is in the hands of the hand with the adjacent side - and the second side is placed near the trigger to set a number of strain gauges, the strain gauge is set on the charm Integrated component connection, and the Whiston Bridge has a built-in shirt; the configuration of the Wheatstone bridge allows the integrated component to measure the exact torque value when the tool body is turned over. The torque value is displayed on the integrated display for the user's reference. Therefore, the twisting force measuring mechanism of the hand tool of the present invention has a fairly accurate torsion strength measurement, which can eliminate the excessive tightness or uncorrection when the locking screw is locked. In order to provide a tool for the creation of more money. Therefore, the present invention is a kind of invention which is quite practical and progressive, and is worthy of being promoted by the industry and publicized to the public. [Embodiment] The present invention relates to a torsion force measuring surface of a hand tool. Referring to the first figure and the second figure, the twisting force measuring mechanism of the hand tool mainly includes a board 1252795 hand type. a hand tool body (1), the hand tool body (1) includes a grip portion (1 1 ) for a user to hold a force, the grip portion (1 1 ) extending at least one end to a plate In the part (1 2 ), the pulling part (1 2 ) is a pulling head (1 2 1 ) capable of turning the screw, and the pulling head (1 2 1 ) is an open wrench in this embodiment. The grip portion (11) is composed of four sides, wherein one side is defined as a first side (1 1 1 ) and adjacent to the first side (1 1 1) The other side is a second side (1 1 2 ); the first side (1 1 1) is disposed near the trigger portion (1 2 ) with four strain gauges (丄i 3 ) And the second side (丄i 2 ) is provided with three strain gauges (ii 3) near the pulling portion (12), and the holding jaw (1 1 ) is provided with an integrated component (1) 1 4), the integrated component (1 1 4) is made of wires and each Wei (丨丨3) is linked, and the most accurate torque value is measured by the configuration of the Long Winston Bridge. The component (i丄4) is equipped with a display (ii 5 ) and an adjustment threat ( Ii 6), the display (丄 for Dongtian ^ can be positive. 70 pieces (11 4) of the torque value of the smoke displayed on it to = Debate, make adjustment threats (1 1 6 ) _ Show 11 ( ii 5 The value of the torque is not zero, the third picture is shown, called the cup L / and other settings; continue to see #-fr Γ ® ^titR 1 . R 2 . R 3 糸 mouth is placed in the grip (1 i ) The second and the first 4 b R42, R4q f 2) strain gauge (113), R43, R44 is the integration tree set between the first side strain gauge (113)' and each strain gauge ( 114) 7 1252795 includes two applied voltages (1 column, and (4)...1 7) and - gang (1 18) for the amount = resistance (4), by Wheatstone as shown in the third figure There is another configuration of the bridge in the bridge. When the manual ~, side (lllhp (1) is pulled, the strain gauge (1) placed on the side of the neck (112) is due to γ = society (4), so it is affected by the force of the forest _, secret integration components and The right ^ does not _ the measured torque change, so that the integrated component (1 1 4) "has the accurate torque value measurement effect.

㈣相騎示,其係本發料工具之扭力制機構使 不思圖,當使用者以手握持手工具本體(i )之握持部(^ ), 再以握持部(11) -端扳動部(12)之扳動頭(i 2 i)套 設㈣固件時,射職_件進行螺簡作;使用者施力於握 持部(1 1 ),以槓桿原理將該螺固件扳轉,此時,做為力臂之手 ’、本體(1)將糾應力作用而產生微幅的變形;在使用手工 八 $本务明手工具之扭力量測機構將該應變規(113) ^至持4 (1 1)第一侧邊(1 1 1 )、第二側邊(1 1 2 ) 罪近板動部(12)之處,而該握持部(11)第-侧邊(工丄 …又規(113)在使用時,將會被縱向的被壓縮或被拉 長、,^亥第二侧邊(丄丨2 )之應變規(工工3 )在使用時,則 會被橫向的f曲變形,故該整合元件(114)可透過設置於第 第—側邊(111、112)之應變規(113)而獲得不 同軸向之扭力量測資訊,並由惠斯頓電橋中财惠斯頓電橋之方 8 1252795(4) The phase riding indication is that the torque mechanism of the hair tool is not considered, when the user holds the grip portion (^) of the hand tool body (i) by hand, and then the grip portion (11) - When the triggering head (i 2 i) of the end pulling portion (12) is sleeved (4), the firing member is screwed; the user applies the force to the grip portion (1 1 ), and the screw is applied by the lever principle. The firmware is turned, at this time, as the hand of the arm, the body (1) will be subjected to the stress correction to produce a slight deformation; the strain gauge is used in the torsion force measuring mechanism using the manual eight-handed hand tool ( 113) ^ to hold 4 (1 1) the first side (1 1 1), the second side (1 1 2) sin near the plate (12), and the grip (11) - The side (worker...the gauge (113) will be compressed or stretched longitudinally when in use, and the strain gauge (worker 3) of the second side (丄丨2) of ^hai is in use. , which is deformed by the transverse f-curve, so that the integrating component (114) can obtain the torque information of different axial directions through the strain gauge (113) disposed on the first-side (111, 112), and The Wheatstone Bridge in the Winston Bridge 8 125 2795

式秦更為準確之扭力值,並將該扭力值顯示於整合元件(U 4 )之顯TFg ( 1 1 5 )上供使用者參考,以免造成該螺固件有 鬆緊度過大或不足的情況發生。 由上所述者僅為用萌釋本發明之較佳實酬,並非企圖據 以對本發明做任何形式上之關,是以,凡有在湖之發明精神 下所做有關本發明之任何修飾或變更者,皆仍應包括在本發明意 圖保叙崎内’其巾如該第―、第二崎之應魏數量亦可視 W 產品之不同而猶作增減者。 所述本毛明手工具之扭力量測機構在結構設計、使用 制性及成本效益上,確實是完全符合產t上發展所需,且所揭 Γ結構發财是具有前所未有的靖構造,所以其具有「新穎 」應揲疑慮’又本發啊較之習知結構更具功效之增進,因此 亦具有「進步性」,其完全符合翻專概有·a轉利Qin Qin more accurate torque value, and the torque value is displayed on the display component TFg (1 1 5) of the integrated component (U 4 ) for the user's reference, so as not to cause the screw to have excessive or insufficient tightness. . It is to be understood that the invention is only a preferred embodiment of the invention, and is not intended to be in any form in accordance with the invention. Or the changer should still be included in the intention of the invention to protect the number of people in the case of 'the towel', such as the first, and the second, and the number of the Wei can be increased or decreased depending on the W product. The torsion strength measuring mechanism of the present Maoming hand tool is in full compliance with the development of production on the basis of structural design, system of use and cost-effectiveness, and the structure of the fortune is unprecedented in the construction of the structure, so It has "newness" and doubts.
