The first and second tripping devices 30, 40 are disposed in the tool head 11, instead of being conventionally known. The handle 12 is generally disposed at 11 1364351. Compared with the prior art, the present invention can effectively shorten the overall length without occupying space, and can greatly simplify the mechanism installed in the handle 12, so that the handle 12 can retain more The space is provided for the central processing unit 6 , the display unit . 70 , the input unit 80 and the power supply unit 9 , and is easy to design.
值得一提的是，該第一、二跳脫裝置3〇、4〇的其中一 者可不δ免置調整單元，而具有固定的跳脫阻力，該第.一、 二跳脫裝置3G、4G的另-者則仍可利用調整單元調整跳阻 力，如此，仍可變化總和跳脫阻力。另外，本發明亦可移 除該應變感測單元50、該中央處理單元6〇、該顯示單元 、該輸入單元80與該供電單元9〇’而成為一種具有雙跳脫 單元的機械式扭力扳手’其與現有僅具單—跳脫單元的同 類產相比，其跳脫阻力具有更大的調變範圍。 综上所述，本發明之扭力扳手，不僅可有效縮短整體 長度，而不佔空間，且可大幅簡化把手内所安裝的機構，It is worth mentioning that one of the first and second tripping devices 3〇, 4〇 can be free of the delta-free adjustment unit, and has a fixed tripping resistance, the first and second tripping devices 3G, 4G The other one can still use the adjustment unit to adjust the jumping resistance, so that the total tripping resistance can still be changed. In addition, the present invention can also remove the strain sensing unit 50, the central processing unit 6〇, the display unit, the input unit 80 and the power supply unit 9′′ to become a mechanical torque wrench with a double trip unit. 'It has a larger modulation range than the existing similar products with only a single-trip unit. In summary, the torque wrench of the present invention can not only effectively shorten the overall length, but also occupy a space, and can greatly simplify the mechanism installed in the handle.
