藉此如圖7、8、9所示，使用者可利用該輸出件20 的驅動。P 23套接一套筒（圖未示）對一螺栓之類的工件（ 圖未示）施加扭力’當該工件被鎖緊到一對應於該第一、 二跳脫裝置3G、40的總合職阻力的預設扭力值後，若使 用者施予該把手12的-外力大於該第―、二#單元31、 32之間的跳脫阻力與該第—、二嗤合單元41、42之間的跳 脫阻力的總和，該等第二嗤合單元32、42即無法再經由該 等第一嚙合單7G 31、41 .繼續帶動被該工件卡緊的輸出件2〇 ’因此，該等第二凸冑323會相對於該等第一凸齒3ιι跳脫 ，使該第二嚙合單元32朝上擠壓該彈性單元34，然後再嚙 合（見圖5);同時，該凸齒422會相對於該凹槽4ιι跳脫 ，使該第二嚙合單元42朝右擠壓該彈性單元44，然後再嚙 合（見圖6) ’此時，使用者即可感覺到明確的跳脫手感， 而該顯示單元70會顯示該應變感測單元5〇所實際量測到 的最大扭力值。 經由以上的说明，可再將本發明的優點歸納如下： 本發明具有跳脫功能與阻力調整功能第一、二跳脫裝 置30、40均是設置於該工具頭n内，而非如習知般設置於 201119802 該把手12,相較於習知技術，本發明可有效縮短整體長度 ’而不佔空間，並可大幅簡化該把手12内所耷裝的機構， 使該把手12可保留更多空間，供該中央處理單元6〇、該顯 示單元70、該輸入單元80與該供電單元9〇進行配置並 易於進行外觀造型設計。 值得一提的是，該第一、二跳脫裝置3〇、4〇的其中一 者可不設置調整單元，而具有固定的跳脫阻力，該第一、 -跳脫裝f 30、40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，其與現有僅具單一跳脫單元的同 類產品相比，其跳脫阻力具有更大的調變範圍。 綜上所it，本發明之扭力扳_，不冑可有效縮短整體 長度’而不佔空間’且可大幅簡化把手内所安裝的機構， 而便於進行電子元件的配置設計與外觀造型設計，故確實 能達成本發明之目的。 | 〜惟以上所述者，僅為本發明之較佳實施例％已，當不 月t·以此限疋本發明實施之範圍’即大凡依本發明申請專利 範圍及發明說明内容所作之簡單的等效變化與修飾，皆仍 屬本發明專利涵蓋之範圍内。 m 12 201119802 【圖式簡單說明】 圖1疋1知Μ數位定扭力板手的立體外觀示意圖； 圖2是該數位定扭力扳手的剖視示意圖·， 圖3疋本發明的數位扭力扳手一較佳實施例的立體外 觀示意圖； 圖4是該較佳實施例的局部分解立體示意圖Thereby, as shown in FIGS. 7, 8, and 9, the user can utilize the driving of the output member 20. P 23 sleeves a sleeve (not shown) apply a torque to a workpiece such as a bolt (not shown) 'When the workpiece is locked to a total corresponding to the first and second trip devices 3G, 40 After the preset torque value of the joint resistance, if the user applies the handle 12, the external force is greater than the tripping resistance between the first and second #31, 32 and the first and second coupling units 41, 42. The sum of the tripping resistances between the second coupling units 32, 42 can no longer continue to drive the output member 2 that is clamped by the workpiece via the first engagement sheets 7G 31, 41. The second tenon 323 will be disengaged relative to the first convex teeth 3, so that the second engaging unit 32 presses the elastic unit 34 upward, and then engages (see FIG. 5); meanwhile, the convex teeth 422 The second engaging unit 42 is pressed to the right to press the elastic unit 44, and then engaged (see FIG. 6). At this time, the user can feel a clear trip feeling. The display unit 70 displays the maximum torque value actually measured by the strain sensing unit 5〇. Through the above description, the advantages of the present invention can be further summarized as follows: The present invention has a tripping function and a resistance adjusting function. The first and second tripping devices 30, 40 are disposed in the tool head n instead of the conventional tool. Generally, the handle 12 is disposed in 201119802. 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. It is worth mentioning that one of the first and second tripping devices 3〇, 4〇 may not have an adjustment unit, but has a fixed tripping resistance, and the first, the tripping dismounting f 30, 40 - The adjustment unit can still be used 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 9〇' into a mechanical type with a double trip unit. The torque wrench 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 effectively shorten the overall length 'without occupying space' and greatly simplify the mechanism installed in the handle, thereby facilitating the configuration design and appearance design of the electronic component. It is indeed possible to achieve the object of the invention. The above is only the preferred embodiment of the present invention, and the scope of the present invention is limited to the scope of the present invention. Equivalent variations and modifications are still within the scope of the invention. m 12 201119802 [Simple description of the drawing] Figure 1疋1 is a schematic view of the stereoscopic appearance of the digital fixed torque wrench; Figure 2 is a schematic cross-sectional view of the digital fixed torque wrench, Fig. 3 is a comparison of the digital torque wrench of the present invention FIG. 4 is a partially exploded perspective view of the preferred embodiment; FIG.
