Description of the Invention: [Technical Field to Which the Invention Is Applicable] The present invention relates to a wrench, particularly an electronic torque wrench having a jumping feel. [Prior Art] Conventional wrenches that can preset the value of the locking torque can be generally classified into two types: mechanical type (for example, U.S. Patent Nos. 4,485,703, 5,129,293 and 5,435,190) and electronic types (for example, U.S. Patent Nos. 4,495,541, 6,981,436 B2 and 6,968,759 B2). Wherein the mechanical wrench generally has a tubular member, a rod member that is framed with the tubular member and that normally aligns the tubular member, a ratchet head that is coupled to the member, and a preload that can be applied to the member. The amount of compression magazine, so that when the wrench applies a torque to the bolt that is greater than the pre-pressure amount, the alignment state of the rod is destroyed and is skewed to hit the tube, so that the user can feel Clear jump feel, however, this type of wrench has the problem that the pre-stress of the compression spring is not easy to set accurately (especially when the compression spring is tired); instead, the electronic wrench is generally attached to The strain gauge on the rod generates a resistance change, and thereby measures the applied torque, and a processing unit of the wrench when the torque applied by the wrench exceeds a predetermined torque value The user will be alerted by driving a vibration motor, a buzzer or a light member. The wrench can accurately set the preset torque value electronically, but 'because its member does not yaw against it Pipe fittings, therefore, the user does not feel a direct and clear trip feeling, which may cause the user to stop applying force too late or too early, resulting in overload or insufficient locking torque, so the user is locked in the same When the group is screwed up, there will be a problem that the screw check is too tight, and the right part of the monument is k, and the bolts of the Taijiaren are too loose. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an electronic torque wrench having a tripping feel that can produce a clear and direct sense of handling as a mechanical torque wrench. The invention has an electronic torque wrench with a tripping feel, comprising a tube unit working unit, a strain sensing unit, a trip unit, and a central processing unit. The tube unit has a surrounding wall extending in an axial direction and surrounding the out-combining space. The working unit is pivotally connected to the surrounding wall and has a head extending from the space of the smudged space, and an abutting portion extending into the accommodating space. The strain sensing unit is disposed on the working unit. The trip unit is disposed in the accommodating space, and the trip unit has a cylinder fixed to the surrounding wall, and is disposed between the abutting portion and the cylinder and is axially a tripping member moving between a pressing position and a tripping position, and a control member disposed on the cylinder block and switchable between a first state and a second state, the cylinder having an accommodation An oil chamber having a hydraulic oil, the trip member having a contact portion adjacent to the abutting portion, and a piston segment extending into the oil chamber, the control member when the control member is switched to the first state Blocking the hydraulic oil from flowing freely in the oil chamber, forcing the tripping member to remain in the pressing position, and causing the contact pressure portion to urge the abutting portion to the working unit parallel to the axial direction when the control When the device is switched to the second state, the hydraulic oil can flow freely in the oil chamber, and the working unit can swing to deviate from the axial direction, and the contact pressure portion is retracted from the abutting portion to the tripping member to move To the trip position. The central processing unit is disposed on the tube unit and electrically connected to the strain sensing unit and the control unit. When the central processing unit determines that the torque sensing value measured by the strain sensing unit is not less than one When the preset # is deficient, the central processing unit can control the control to switch to the second state. BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the accompanying drawings. β Before making a detailed description, it is to be noted that in the following description, similar elements are denoted by the same reference numerals. <Reading Figures 1, 2, and 3, a first preferred embodiment of the electronic torque wrench having a tripping feel according to the present invention, the electronic torque wrench having a tripping feel includes: a tube unit 10 and a working unit 2 The 应变, _ strain sensing unit 3 〇, a trip unit 40, a central processing unit 50, an input unit 60, a display unit 70, and a power supply unit 8A. The official unit unit 1 has a surrounding wall u extending along an axial direction and surrounding an accommodation space 12. The working unit 20 is pivotally connected to the surrounding wall u, and has a head portion 21 extending from the valley space 12, an abutting portion 22 extending into the receiving space 12, and a connecting line along the axial direction. A neck portion 23 between the head portion 21 and the abutting portion 22, a groove 24 formed in the neck portion 23 along the axial direction X, and a swing center 25. The sinus strain sensing unit 30 has a strain 1322071 body 31 mounted in the recess 24, and a strain gauge 32 mounted on the strain body 31. It is to be noted that the strain sensing unit 30 of the present invention may of course be composed of only one or more sheets of strain gauges 32 and that the strain gauges 32 may be as in the prior art (for example, U.S. Patent No. 4,495,541, 6,981,436, 2) 6968759Β2) is directly attached to the side plane of the neck section 23. The trip unit 40 is disposed in the accommodating space, and the trip unit 40 has a cylinder 41 locked to the surrounding wall u by two bolts 13 , and is disposed at the abutting portion 22 and the cylinder A tripping member 42 between the 41 and movable along the axial direction between a pressing position (see FIG. 1) and a tripping position (see FIG. 4) is disposed on the cylinder 41 and is A control member 43 that switches between a first state (see FIG. 1) and a second state (see FIG. 4), and a connection with the cylinder 41 drives the tripping member 42 from the trip position (see FIG. 4) The elastic reset group 44 moving toward the forced position (see Fig. 1). The cylinder block 41 has an oil chamber 411 accommodating a hydraulic oil 415. The oil chamber 411 has a first space 412, a second space 413, and a first space 413. The flow path 414 of the two spaces 412, 413. In the present embodiment, the trip member 42 is composed of a contact portion 421 adjacent to the abutment portion 22 and a piston segment 422 adjacent to the cylinder block 41. The contact pressure portion 421 has a contact concave curved surface 423 that can contact the abutting portion 22, and a through-groove 424 opposite to the contact concave concave surface 423, and an outer curvature of the abutting portion 22 It is a concave arc corresponding to the concave concave curved surface 423. The piston section 422 has a coupling head portion 425' that engages in the through-hole 424 and a piston head 426 that extends into the first space 412. 8 1322071 The control member 43 has a valve stem 431 switchable between the first and second states (see Figs. i, 4). In the present embodiment, the control member 43 is a solenoid valve. When the valve stem 431 is switched to the first state, the valve stem 431 is extended to block the flow passage 414, and the hydraulic oil 415 is prevented from flowing freely from the first two chambers 412 toward the second space 413. When the valve stem 43 is switched to the second state, the valve stem 431 is withdrawn from the flow passage 414, so that the flow passage 414 is ash-connected to the first and second spaces 412, 413 to make the hydraulic oil 々Μ Free flow in the oil chamber 411. The elastic return group 44 has two return springs 441 which are abutted between the contact pressure section 421 and the cylinder 41 along the axial direction, a return oil piston 442 disposed in the second space 413, and an offset A return spring 443 is connected between the oil return piston 442 and the cylinder 41. The oil return piston 442 is movable between a first position (see FIG. 1) and a second position (see FIG. 4). The central processing unit 50 is disposed in the accommodating space 12 and electrically connected to the strain gauge 32 and the control member 43. In this implementation, the central unit 40 can be a circuit board and has a conventional Wyeth bridge, an amplifier, a recorder, a microprocessor, etc. However, this is not the focus of the request, so it is not Let me repeat. The input unit 60 and the display unit 7 are disposed on the tube unit 10 and are electrically connected to the central processing unit 5, and the user can apply a predetermined reference to the maximum torque through the input 60. The value is input to the central processing unit 50 and displayed by the display unit 70. 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 9:8: is electrically connected to the control unit 43 and the central processing unit 5A. In the present example, the power supply unit 5 can be a battery. In this case, as shown in FIG. 1 and FIG. 2, when the latter uses the head 21 to be sleeved: a sleeve (not shown), such as a workpiece (not shown), applies a torque, and the central processing unit When it is determined that the strain sensing unit 3 is measured that the torque value is less than the preset reference value, the central processing unit 5 is configured to control the valve stem 31 to remain in the first state to prevent the hydraulic oil from being hydraulically deformed. The second/station 412 flows toward the second space 413. Thus, the hydraulic oil 415 between the piston head 426 and the valve stem 31 forces the tripping member 42 to be held in the pressing position. The (four) concave curved surface 423 of the contact pressure portion 421 is urged to the abutting portion 22 to the working unit 2A parallel to the axial direction X. At this time, the oil return piston 442 is located at the first position. Conversely, as shown in FIG. 2 and FIG. 4, when the user applies a force, the central processing unit 50 determines that the torque value measured by the strain sensing unit 3 is not less than the preset reference value. The central processing unit 5 will control the valve 431 to switch to the second state, so that the flow path 414 is restored to communicate with the first and second spaces 412, 413. Thus, the hydraulic oil 415 can no longer block the contact. . The force applied by the cymbal 22 to the detaching member 42 can be oscillated relative to the tubular unit 10 to the axial direction X to collide with the tubular member 10, and the abutting portion 22 is The tripping member 42 is forced to move toward the cylinder 41 along the contact concave curved surface 423, and the contact portion 421 is moved away from the abutting portion 22 to the tripping member 42 to move to the trip position. At this time, the return springs 441 are compressed by the contact pressure portion 421, and the hydraulic oil 415 in the first space 412 is squeezed by the piston head 416 10 1322071 to move into the first space 413. And forcing the oil return piston 442 to move to the second position ' to compress the oil return spring 443. The field user no longer applies force, and the elastic restoring force of the return springs 441 can reversely return the tripping member 42 to the pressing position. In the process, the elastic restoring force of the oil return spring 443 can also The oil return piston 442 is reversely reset to the first position, such that the retracted piston head 426 cooperates with the reset oil return piston 442 ′ to reversely flow the hydraulic oil 415 from the second space 413 to The first space 412, at this time, the central processing unit 5 can control the valve stem 431 to switch back to the first state, so that the touch section 421 can again tighten the abutment 22 to the guard Unit 2G is parallel to the axial bore (see Figure 1). Through the above description, the advantages of the present invention can be further summarized as follows: 1. The present invention can control the fluidity of the hydraulic oil 415 by precisely setting the preset reference value for applying the torque in an electronically controlled manner. The tripping member 42 moves to the tripping position in time, and allows the user to feel a direct and unambiguous tripping feeling. Therefore, the user of the present case can stop applying force at an appropriate time according to a clear trip feeling. When the user of the case locks the same set of bolts, all the bolts can be locked with the same torque without the problem of overload or insufficient locking torque. 2. The compression spring of the conventional mechanical wrench must generate a great amount of pre-pressure to withstand the torque with the applied torque. However, the present invention uses the hydraulic oil 415 to withstand the tripping member 42 and then borrows The fluidity of the hydraulic oil 415 is controlled by the switching of the control member 43. Therefore, the control member 43 can control the valve stem 431 with a slight force to compete with the applied torque. 11 1322071 The preferred embodiment is similar to (4) - preferably (4), with the difference that
當該閥桿431切換至該第一狀態（見圖5)時，該閥桿 431是延伸入該流道414,而縮小該油室4ιι的容積，迫使 該跳脫件42保持於該迫緊位置（見圖5)上；相反地，者 該閥桿431切換至該第二狀態（見圖6)時，該閑桿431 ^ 退出該流道4M，而增大該油室411的容積，使該工作單元 2〇可受力偏擺至使該跳脫件42移動至該跳脫位置（見圖6 h如此第二較佳實施例亦可達到與上述第—較佳實施 例相同的目的與功效，並由於該閥桿431具有擠油功能， 故能省略該彈性復歸組44。 歸納上述，本發明之具有跳脫手感的電子扭力扳手， 不僅可以電子控制方式精準設定施加扭力的預設參考值， 更可如同機械式扭力扳手般產生明確且直接的跳脫操作手 感’故確實能達到發明之目的。When the valve stem 431 is switched to the first state (see FIG. 5), the valve stem 431 extends into the flow passage 414 to reduce the volume of the oil chamber 4 ι, forcing the tripping member 42 to remain in the tight Position (see FIG. 5); conversely, when the valve stem 431 is switched to the second state (see FIG. 6), the idle lever 431 ^ is withdrawn from the flow passage 4M, and the volume of the oil chamber 411 is increased. The working unit 2 is biased to move the tripping member 42 to the tripping position (see FIG. 6h such that the second preferred embodiment can achieve the same purpose as the above-described first preferred embodiment) And the function, and because the valve stem 431 has a squeeze function, the elastic reset group 44 can be omitted. In summary, the electronic torque wrench with the tripping feel of the present invention can not only accurately set the preset torque application by electronic control. The reference value, like a mechanical torque wrench, produces a clear and direct tripping operation feel, so it can indeed achieve the purpose of the invention.
