The upper strain gauge generates a resistance change, and by measuring the applied torque, when the torque applied by the wrench exceeds a predetermined torque value, a processing unit of the wrench is used by A vibration motor, a buzzer or a light member is used to warn the user that the wrench can accurately set the preset torque value electronically, but 'there is no yaw impact on the pipe member due to its lever' 1 The user can't feel (4) the clear and clear feeling of jumping, which may cause the user to stop applying force too late or too early, resulting in overload or insufficient locking torque. Therefore, the user is locking the same set of thread inspection. At 1335857, it is often the case that some bolts are locked too tight, but some bolts are too loose. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an electronic torque wrench having a tripping feel that produces a clear and direct tripping operation feel like a mechanical torque wrench. The electronic torque wrench 'with a tripping feel of the present invention comprises a tube unit, a working unit, a strain sensing unit, a trip unit, and a central processing early.

It is to be noted that the present invention The strain sensing unit 3ω 3G may also be composed of only the strain 1335857 gauge 32 of the chip, and the strain gauge 32 may be directly attached as in the prior art (for example, US Pat. Nos. 4,495,541, 6,981,436 B2, and 6,968,759 B2). On the side plane of the neck portion 23. The trip unit 40 has a driven member 41' disposed on the handle portion 22 and a control member 42 disposed on the handle portion 22. The driven member 41 There are two balls 411 respectively movably received at the two open ends of the through hole 223, and the balls 411 can be switched between a forced state (see FIG. 2) and a trip state (see FIGS. 4, 5). The control member 42 has an electromagnetic coil 43 disposed in the chamber 221 and electrically connected to the central processing chamber τ, 50. An induction shaft 44 movable in the guide groove 222 and movable between a first state (see FIG. 2) and a second state (see FIG. 5), and a shaft abutting the induction along the axis a compression spring 45 between the rear end of the shaft 44 and the end of the handle 22. The induction shaft 44 has a tapered front end portion 44 of the head portion 21 of the jade unit 2 () outside the front end portion 441 The diameter decreases along the axial direction toward the head η. When the sensing shaft 44 is in the first state, the balls 4 are in the pressing state, when the sensing shaft 44 is in the second state. The ball processing unit 5G is disposed in the accommodation portion 12 of the pipe unit iq, and is electrically connected to the strain gauge 32 and the electromagnetic coil 43. In an example, the central processing unit 5G can be a circuit board, and has a well-known Wyeth bridge, an amplifier, a recorder, a microprocessor, and the like, and is electrically connected to the strain gauge 32 by wires (not shown). The electromagnetic coil 43 is electrically 'however, this is not the focus of the present (4) request, so it will not be described again. 8 The input unit 60 and the display unit 7() are set. The tube unit=upper and is electrically connected to the central processing unit 5〇, through which the user can input a preset reference value of the maximum torque to be input into the central processing unit 50, and the display unit is (4) This part is a common design of the current electronic torque wrench, and will not be described again. The power supply unit 80 is installed in the accommodating space 12, and the power supply unit 80 is electrically connected to the electromagnetic coil 43 and the central processing unit 5. In this embodiment, the power supply unit 5 can be a battery. Thereby, as shown in FIG. 23, when the user uses the head 21 to sleeve-sleeve (not shown), a bolt or the like. The workpiece (not shown) applies a torque, and the central processing unit 5G measures the strain sensing unit % - the torque value is less than the preset reference material, and the central processing unit 5 does not drive the electromagnetic The coil 43 generates a magnetic attraction, and therefore, the induction shaft 44 can be held in the first state 'between the axial direction between the balls 4 ι'. In this case, the induction shaft 44 is the same as the balls 411. Splicing, forcing the cough and other balls 4η to remain in the tight state And pressing the surrounding wall outward/therefore, the work order S 20 cannot be pivoted with the swinging center 25, and is swung relative to the tubular unit 而) and remains parallel to the axial χ on the real f status. Conversely, as shown in FIGS. 3, 4, and 5, when the user applies a force, the central processing unit 50 determines that the measured force value of the strain sensing unit 3 is not less than the preset reference value. At this time, the central processing unit % generates magnetic attraction force to attract the induction shaft 44 compared to the electromagnetic coil 43 to move the arbor shaft 44 from the first state (see FIG. 2) to the second state.

工作單元2G即可以該擺動“25為軸心,相對該管件單 擺動至偏離該軸向X’而與該管件單元1G產生撞擊。 此後’當使用者不再施力,且,該中央處理單元50停 止驅使該電磁線圈43產生磁吸力時,該壓縮彈菩45的彈 性㈣力可驅使該感應軸捍44反向復位至該第_狀態而 使該等滾珠41】再移動至該迫緊狀態,如此,該等滚珠川 可再度迫緊該圍繞壁U,使該工作單元2()實質 軸向X (見圖2)。 經由以上的說明,可再將本發明的優點歸納如下: 本發明除了可以電子控制方式精準設定施加扭力的預 設參考值外,更可藉由該電磁線目43控制該感應轴桿44 的移動,.使該等滾珠411適時鬆開該圍繞壁u,而使咳工 作單元20可相對該管件單元1()職,進而讓使用者感覺 到直接且明確的跳脫手感,因此’本案使用者可根據明確 的跳脫手感,而在適當的時間上停止施力,如此,本案 用者在鎖固同一組螺栓時,即可以相同的杻力鎖固所有的 螺栓’而不會發生鎖固扭力過載或不足的問題。 參閱圖6,為本發明的-第二較佳實施例’該笫二較佳 貫施例是類似於該第一較佳實施例,其差異之處在於: 10 1335857 該感應轴桿44具有一可移動地設置於該導槽222内的 導滑段46 ’及—與該導滑段46連接的桿段47。 该導滑段46是由一導滑塊461及一螺接於該導滑塊 461上的撞環462構成’該導滑段46具有一沿該軸向X設 置的連接孔463,該連接孔463具有一成形於該導滑塊461 上的大孔徑部464,及一貫穿該擋環462且孔徑小於該大孔 徑部464的小孔徑部465。The working unit 2G can swing the "25" as an axis, and the tube member 1G is oscillated to deviate from the axial direction X' to collide with the tube unit 1G. Thereafter, when the user no longer applies force, and the central processing unit When the stop of driving the electromagnetic coil 43 to generate a magnetic attraction force, the elastic force of the compressed projectile 45 can drive the induction shaft 捍 44 to be reversely reset to the _th state to move the balls 41 to the forced state. Thus, the balls can again force the surrounding wall U to make the working unit 2 () substantially axial X (see Fig. 2). Through the above description, the advantages of the present invention can be further summarized as follows: In addition to accurately setting the preset reference value for applying the torsion force in an electronically controlled manner, the movement of the induction shaft 44 can be controlled by the electromagnetic wire 43 to cause the balls 411 to loosen the surrounding wall u in a timely manner. The coughing work unit 20 can be opposite to the tube unit 1 (), thereby allowing the user to feel a direct and unambiguous feeling of jumping off, so that the user of the present case can stop exerting force at an appropriate time according to a clear sense of jumping off the hand. So, this case is used When the same set of bolts are locked, all the bolts can be locked with the same force of force without the problem of overload or insufficient locking torque. Referring to Figure 6, the second preferred embodiment of the present invention The preferred embodiment is similar to the first preferred embodiment in that: 10 1335857 the sensing shaft 44 has a guiding portion 46' movably disposed in the guiding slot 222 and a rod segment 47 connected to the guide segment 46. The guide segment 46 is formed by a guide slider 461 and a striker 462 screwed onto the guide slider 461. The connecting hole 463 is disposed in the axial direction X. The connecting hole 463 has a large aperture portion 464 formed on the guiding slider 461, and a small aperture portion 465 extending through the blocking ring 462 and having a smaller aperture than the large aperture portion 464. .

Since the outer diameter of the connecting portion 471 is smaller than the diameter of the large aperture portion 464, and the outer diameter of the shaft portion 472 is also smaller than the aperture of the small aperture portion 465, the rod portion 47 can be opposite to the guiding portion. The slider 46 moves in the lateral direction γ. As shown in FIG. 6, when the sensing shaft 44 is in the first state, the shaft portion 472 of the rod portion 47 is interposed between the balls 々 n along the axial direction.
