Description of the invention: [Technical field to which the invention pertains] Finer than a type of force wrench, in particular, a digital type torque wrench having an electromagnetic force tripping member. [Prior Art] The conventional torque wrench system - the hollow f-shaped wrench sleeve f-end is configured with a plate =, the other end configuration - the torque adjustment screw. The inside of the wrench sleeve is provided with a machine, and is coupled to the wrench head, and a spring is disposed at one end to be coupled to the jumper and the other end is coupled to the adjusting screw. The force acts on the trip mechanism to form a predetermined torque. =-The user operates the torque wrench and the operating torque is less than the preset torque. (4) The jump wire is to be generated. (4) When the torque is turned into a torque, the tripping mechanism is dislocated. The wrench head has the ability to swing, and the torsion wrench cannot output the torque normally. The torque wrench of the detachment is set by the torque wrench and the structure of the jumper is a link mechanism. Therefore, the t of the trip mechanism is slower; in addition, the adjustment of the torque is achieved by adjusting the screw and the spring 'The adjustment method is mechanical, so after 2^ time, the elastic component will produce aging, deformation or elastic fatigue. 2 As a result, the preset torque setting will be inaccurate, and the operating torque will be applied. Does not match the preset torque. ^ The use of digital devices for traditional tools is currently very popular. For example, in torque wrenches, strain gauges, _ operating torque, ίϊίί preset torque. When the operating torque matches the preset torque, do not let the user know that the user will stop the operation. However, if the user's heart, § Fu continued to pull the wrench to apply force to the workpiece, the work torque must be 'in other words' although the digital torque setting and detection can be r, but if the user is negligent, the warning effect is the same The virtual sound of t t 动 提供 提供 以 以 以 以 以 以 是 操作 操作 是 操作 操作 操作 操作 操作 & & 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有Digital Torque Wrench (2), one of the inventions of the invention is to provide a number ^ ^ with itr set money for the torque to make a fine purchase === force firm member, according to this _ operation torque and pre- The twisting has a digital torque wrench (2), which has ίϊίϊϊί to form a structure _ effect. - The wrench head has a hand (2) containing - the body, the strain, in the ===== power control ii with the hand, and with When the strain gauge force jumps off the configuration and the live scale extends to the pre-mixed force, the magnetic supply is normally pulled: the Wei-wrench surface is moved, so that the force can be jumped out and the brain is purchased. The magnetic head can be unrestricted, the purpose of the invention, and the work The preferred embodiment is described in detail with reference to the figure 1376294. [Embodiment] Referring to FIG. 1A, a digital torque wrench 1 〇 includes a ϊ 4m30 set at one end of the body 2〇. a torque setting tube fitting, the plate hand 30 and the - head two should be extended to the side of the head 32 and placed in the body, the torque setting device 40 is provided by the user to input a preset 6 The operating device with torque value. The 1st figure is shown in the figure of '1' and the digital torque wrench U, which is with the wood and the wrench of the hand is in the financial reading force wrench η torque, ί undetermined The device 'is a fixed preset at the factory and has two kinds of torque wrenches (not shown). The internal comparator 8 is electrically connected to the electromagnetic force tripping mechanism 70. Section (A) of Figure 1C reveals the strain sensor, ί t〇r^4〇=the preset torque input by the fixed device 40 is transmitted to the _force setting shock 40 and the comparator 8 ;^ "合=姑装置. The operation process 'the strain gauge 6 摘 measured the t number in the operation and transmits it to the comparison 11 80, the two signals are compared in the comparison 51 r ... part of the pre-existing the strain gauge 60 signal The torque value can be recorded in the comparator 80 process, and the current strain "two-dip 0f can have the function of the memory torque value. The operation operation torque is converted into a signal transmission to the μ-sounding to the torque _ set torque tree, If the condition is met, the electromagnetic force tripping mechanism 7 〇 actuation = normal operation, otherwise the torque wrench can continue to be operated. 1376294 Please refer to Figure 2, the strain gauge 6 配 is equipped with the wrench J 34. * The embodiment discloses that the two strain gauges (9) are respectively disposed in the strain section ^ == ^ 34 means that the hand is 3° when the hand is supplied with the torsion force; The absorbing--, ^^ is more eight-body and the ll' electromagnetic force tripping member 70 has a variable section 34. The 'moving rod 72, one end of the movable rod 72 is preset with respect to the response rod setting device 40 Torque, and the live action, the contact portion 34 of the wrench head 30, the movable rod 72 and the Zhaofeng merchant 72 retreats. As a result, 72 no longer limits the wrench head m to 3 34 no contact, so the movable rod without J and then the workpiece torsion force Er Lu 'the wrench head 3 〇 can swing freely 72 Mt: 2 The tripping mechanism 70 disclosed in the embodiment is connected to the strain section 34.74 of the movable rod and is placed against the strain section 34 or has a universal joint. Segment 34, and the direction automatic adjustment component 74 pushes against the position or angle of the hand m which can be limited to the direction from the _^^74, and can change the workpiece direction, so the relative position or angle of the wrench ^2 2', the movable rod 2 and the strain section 34 are angled, and the direction changes from the direction of the integral element 74 to the direction 1376294, so the wrench head 30 can swing freely and cannot apply a torque to a workpiece. FIG. 5 is a perspective view of a digital torque wrench 10 according to another embodiment of the present invention. The main body 20 includes a body 20, a wrench head 30, a torque setting device 4, at least one strain gauge 60, and an electromagnetic force tripping member 7 The composition of each member's last name and corresponding spatial form are equivalent to the previous embodiment, so no longer The difference between this embodiment and the previous embodiment is that the other portion 34 of the wrench head has a through hole 36. The movable rod g portion of the electromagnetic force tripping member 7 is opposed to the threading 36. When the digital torque wrench 10 provides a torque to a workpiece, the live rod 72 extends and is placed on the through hole 36' such that the movable rod interferes with the head 30, so that the wrench head 3 cannot swing. The torque wrench 30 can move the workpiece. ' Referring to Fig. 6, when the operation detected by the strain gauge 60 is reversed, the movable rod 72 of the force tripping member 70 is retracted; the perforation 36 . As such, the movable rod 72 has no contact with the wrench head 3's 34, so the movable rod 72 no longer limits the wrench head 3''. In other words, the wrench head 30 can swing freely and can no longer apply torque to the workpiece. Please refer to FIG. 7 , and the present invention further discloses that the digital two 10 is composed of a body 20 , a wrench head 30 , a torque setting of the agricultural device 4 , at least the variation 60 and an electromagnetic force tripping member 7 . composition. The spatial shape corresponding to each member 皆' is the same as that of the previous embodiment, so the σ is not described. The difference between the embodiment and the foregoing embodiment lies in the electromagnetic force jump ^ ° = the end of the movable rod 72 passes through the wrench head The strain section 34 of 30 is opened at a force 36' and a push block 76 is disposed at the end of the movable rod 72. The teeth § the movable rod 72 assumes a contracted state. The push block π is placed against the surface of the strain section 34 of the head 30, so that the flipping of the pulling head 3 is so that the X piece is pulled. Referring to FIG. 8, when the strain gauge 6α is operated to the torque and preset = 'the movable rod 72 is extended so that the push block 76 is far from the strain section 34, the aperture of the hole 36 is much larger than the outer diameter of the movable rod 72, Therefore, the wrench ί 72 ^&_ movement ° as such, the wrench head 3 〇 can no longer apply torque to the workpiece. 79财9图,##使_打顿王王作作, then the action bar = extended so that the push block 76 pushes the wrench head 3〇 is inclined, so that 1 pull = head 3G after · k It is restricted between the wall surface of the main body 2G and the push block 76, and the hand 3〇 is inclined, so that the gap between the movable rod 72 and the through hole 36 becomes small, so that the wrench head 3G cannot swing freely. As a result, the user can operate the wrench smoothly. β阅1Q图, this embodiment is when the action #pre-failed condition of the sense gauge 60 matches, the activity of the electromagnetic force tripping mechanism 70 ^=retracts the head of the wrench The strain section 34 of 30 is separated from the body 20 and pushed, and the limitation of the second 6 is so - the wrench head 3 can no longer impart a twisting effect on the workpiece. According to the structure of FIG. 7 to FIG. 1G, and combining the two structural forms, the eleventh figure is shown. When the working operation is performed using the wrench, the movable rod 72 is extended, and the wrench head 30 is inclined so that The rear section is limited between the two push blocks 76, and 3〇 cannot swing freely. In this way, the user can operate the wrench smoothly. The structure shown in Figure 12 shows that when the operating torque is in accordance with the preset torque, the moving rod 72 is retracted, so that the strain section 34 of the wrench head 30 is separated from the limit of the body 20 and the push block 76, so that the plate The rear section of the 3 手 hand can be ridden on the second push block 76, so that the 3G of the hand can not be towed by the torsion. Please refer to the thirteenth embodiment of the present invention to disclose the outer rod of the movable rod 72 of the electromagnetic force tripping mechanism 7〇. When the working operation is performed using the wrench, the movable lever 72 is extended, and the spring 92 exerts a force on the push block %, thereby providing a better pushing force to the wrench head 3〇. When the operating torque is preset with 1376294, the rotation 72 is retracted and the shape of 92 is made to make the wrench 3〇〇ις. According to the design of the structure of the crane, the equivalent of the crane H is as shown in the figure, the electromagnetic force mechanism 70 and the spring 92 are matched. Set on the opposite side.
