Shifting-Spanner, Pipe-Tongs And The Like」專利案， 其係為一種多用途之扳手（wrench)，扳手具有一個固定爪 (stationary jaw)與一個活動爪（movable jaw)，活動爪透 過一個彈簧（spring)的頂推而能夠於導軌（guide)上往復 滑移。當使用者欲扳轉螺帽時，轉動扳手可讓固定爪及活 動爪帶動螺帽旋轉。當使用者欲將扳手移動至下一個扳轉 位置時，以相反方向轉動扳手’可讓活動爪後退並壓縮彈 簣而不會帶動螺帽旋轉。反覆操作前述動作即可達到鎖緊 或放鬆螺帽的效果。 201143991 故 ，是活動爪僅依靠彈簧_推力而接觸在導軌上、人 很谷祕生晃動的問題，*且容易因碰撞或扳手摔 ^ *導致雜爪脫離軌道的問題。又當活動爪脫離軌 道之後’彈簧也很容易跟著脫離而掉落，為不良之設計。 再者彈簧的-端是固定在扳手固定爪的孔内彈箸 的另1卻裸露在外’如此使得彈簧裸露於外的—端容易 因撥^時的相’而與固定爪的孔口處摩擦導致壓縮過程The Shifting-Spanner, Pipe-Tongs And The Like patent, which is a versatile wrench having a stationary jaw and a movable jaw, the movable jaw is transmitted through a spring ( The push of spring can reciprocate on the guide. When the user wants to turn the nut, turning the wrench allows the fixed claw and the movable claw to rotate the nut. When the user wants to move the wrench to the next turning position, turning the wrench 'in the opposite direction' allows the movable claw to retreat and compress the magazine without rotating the nut. By repeating the aforementioned actions, the effect of locking or loosening the nut can be achieved. 201143991 Therefore, it is a problem that the movable claw only touches on the guide rail by the spring_thrust, and the person is very swaying, and it is easy to cause the claw to be off track due to the collision or the wrench. When the movable claw is off the track, the spring is also easy to fall off and fall, which is a bad design. Furthermore, the end of the spring is fixed in the hole of the wrench fixing claw and the other one is exposed, so that the spring is exposed to the outside - the end is easily rubbed against the hole of the fixed claw due to the phase of the dialing Causing the compression process

In severe cases, the spring will be permanently deformed and damaged. Moreover, the four (4) reports (4) (4) oily and fine dust dust will not only affect the compression effect of the spring, but the dust is more likely to cause obstacles in moving the claws. Later, a patent for the "〇pen End Ratchet Wrench" patent, No. 3,695,125, which is an open type ratchet wrench, was designed. The wrench has a fixed jaw and a support portion. The support has a spring and a pawl. Two separate caps are fixed to the wrench. Both sides of the support portion accommodate the spring and the claw block, and the claw block can reciprocate in the support portion by pushing the spring. It is designed to accommodate the spring between the two cover sheets without being exposed to the outside, and the claw block has a stop shoulder (st〇p sh〇ulder) which can be blocked inside the cover sheet to prevent the claw block from being ejected. Out of the support department. However, the two cover sheets are detachable and separate, and it is easy to separate the cover sheets by collision or a wrench falling to the ground, causing the claw pieces to be separated from the support portion. When the claws are separated from the support portion, the spring is also easily detached and dropped, which is a bad design. While the claw block only depends on the top thrust of the spring to contact 201143991 in support. The problem is that the claws are still prone to sloshing. Furthermore, the end of the spring is only abutted against the inner surface of the fixed claw, and the other end of the spring abuts against the claw block. The spring itself is not covered by the whole circumference, and is easily impeached by collision or repeated compression. Deviation from the original position, eventually leading to the claw-free: ... the method is normally pushed by the bomb X and loses the effect of reciprocating motion ^ and when the claw ghost is pushed into the supporting phase, a gap will be generated between the cover sheet and the claw block.

All the 'wrench' can not withstand high torque, that is to say, this kind of wrench can only be applied to round pipe type items. Because the round pipe type is hollow design, the reaction force generated when the plate is moved is small (otherwise hollow pipe) It is easy to change), so the wrench design does not need high torque. In addition, the second spring end is received in the hole of the sliding claw, and the other end protrudes out of the hole, so that the spring protrudes from the end of the hole. It is easy to bend and bend, and the friction with the orifice causes the compression process to be unsmooth.

The wrench has a pair of stationary jaws 'opening a space inside and outside of one of the fixed claws, a movable plate is provided in the space, and two movable plates are provided on the moving plate. The slot (sl〇t) is then provided with two pins on the fixing claw to pass through the space and the two slots of the moving plate so that the moving plate does not leave the space. The wrench also has a hole in the space (11〇1〇 to accommodate a spring). One end of the spring is arranged in the hole, and the other end is extended outside the hole to push the moving plate. Two of the moving plates are provided. The slots are respectively formed by a short straight section and a long straight section (long secti〇n), and the short straight section has an angle with the long straight section, so that the moving plate can perform two-stage linear movement when reciprocating. Although the wrench can make a two-stage linear movement, the spacing between the moving plate and the fixed claw is increased, but the problem of moving plate jamming is easy to occur in practical use, especially in the intersection of a short straight line segment and a long straight line segment. At the same time, the wrench is used for smoothness in the reverse rotation. Moreover, one end of the spring is disposed in the hole and the other end is extended outside the hole, so that one end of the spring protruding hole of 201143991 is easily bent by the broadcast pressure. Friction with the orifice causes the compression process to be unsmooth, and in severe cases, it will cause the permanent death of the phthalocyanine. - = can not be damaged. Even worse, because the moving plate has a straight line of _ segment, it is more likely to cause the magazine to be produced. The problem of degree of bending damage. Furthermore, since the design of the conventional single linear groove causes the variation of the distance between the moving plate and the fixed claw to be small, a two-stage linear groove must be provided to increase the variation of the pitch, but This will result in an increase in the area of the moving plate, or an increase in the area of the fixed claws, which will not be able to reduce the space for the open-end wrench. Of course, the wrench cannot extend into a small space for reciprocating movement. The moving plate area is increased, and the fixed claws are deliberately reduced. As with the design of the wrench, the long straight line segment or the short straight line segment is missing from the fixed claws, so that the dust is accumulated on the moving plate. In the tank, the last step will form a hindrance when the moving plate is linearly slipped. In addition, since the space is completely open inside and outside, the reaction force of the moving plate when the plate turns the nut is transmitted to both pins. However, the torque that the pin is subjected to cannot be too high, so it is easily damaged, making the wrench unusable for high-torque turning operations. Refer to US Patent Publication No. 2009/01 No. 93941 "Ratchet Wrench" patent, which is a ratchet type adjustable wrench. The wrench has a first jaw and a second jaw, and the first claw and the second claw are both provided. In a jaw support, and the first claw can be driven by a worm, the claw support portion is provided with a full open inner and outer track, and the second claw is disposed in the trajectory. The claw support portion is provided with a pin extending through the rail, and the second claw is provided with a straight 8 201143991 linear open groove (openi open groove, "two claws cannot be supported by the claw support portion and the second claw -_ Spring element (bi. claw support.

The structure can be turned over by the (four) rods to achieve the effect of reversing at different times. However, there are too many parts of the integral wrench, and the structure is opened through the porous hole, which also causes the strength of the wrench body to decrease. Moreover, because the obstinating is full of internal and external openness, the second part of the anti-xian force that the second claw bears when the plate is turned into a nut is handed to the pin, so that it is easily damaged after being pinned. In particular, although the second claw has a surface that can slide relative to the claw supporting portion, the plane is a guiding foundation for providing the sliding claw to move outward when being pulled, so the plane cannot effectively withstand the torque. Instead, the reaction will be transmitted to the pin due to relative slip, which is not a good design. In addition, due to the design of the linear movement of the second claw, in order to increase the amount of change in the distance between the second claw and the first claw, it is necessary to lengthen the open groove in the second claw to achieve the same. effect. However, in such a design, the second claw is pushed out of the nut, and the open groove of the second claw is exposed outside the claw support portion, so that the open groove and the elastic member therein are easily stained with oil. Moreover, it will adhere to the dust and affect the compression effect of the elastic element 201143991. This causes the sliding movement of the second claw to be unsmooth. This is a problem that the wrench must solve. The ship forms a traditional wrench that cannot be reciprocated. 〇 Including the aforementioned patents, as well as U.S. Patent No. 4,158,975, U.S. Patent No. 4/158, No. 1516, 2010/0083797, all of which have a common problem. The problem is that the wrench in the open form is limited in torque. The original is that the 'pgu secret' wrench has a problem of elastic expansion when the torque is too large. For example, when the user finds that the torque is insufficient when the turning is performed, a lengthened metal tube is sleeved in the grip, thereby increasing the force arm when the turning is performed, so as to enable the turning operation of the large torque. However, when the screw is locked to a certain extent, the reaction force is greater than the elastic deformation ability of the wrench in the open form, and therefore, the problem that the plate expands and the expansion becomes large may occur, which may cause the wrench to be ineffective. Connected to the screw, so that the movable claw block is separated from the working surface of the screw, and then the most prone to the disadvantage is that the end angle of the screw is worn, so that the plate turns motion = again: continue to turn the work, - can not The plate turning operation with high torque is performed, and on the other hand, the screw is damaged. Another problem is that most of the movable claw blocks in the aforementioned patent case only have a single-face abutting on the force-receiving surface of the screw, such as the opening wrench wrench 'When the open-end wrench engages the screw, the movable block is located on one side of the open-end wrench to force the screw, and the claw block only abuts the screw with a single face, that is, one side of the screw is only affected by 201143991 ° The spoon is limited, so when the open-end wrench turns the screw, the open-end wrench and the cymbal = there is a possibility of relative sliding, which causes the process of turning the screw to be unstable, and the torque cannot be effectively improved. Furthermore, 'because the side of the screw is only limited by a single direction, and the over-rotation of the screw is stable, the claw and the screw will slide relatively easily = the problem of the claw or the screw' The piece is easy to slip and can no longer continue to work.

The fourth positive force receiving surface 13 201143991 94A of the crop (10) and the third positive force receiving surface 93A. The first plane 241 of the second jaw 24 is substantially parallel to the force applying plane 231 of the first jaw 23. 25 has an thrust plane 251 facing the wrench 26, and an angle between the thrust plane 251 of the throat 25 and the force applying plane 231 of the first paw 23 and an angle of one hundred and twenty degrees, so that the throat 25 The pushing plane 251 can correspond to the second positive force receiving surface 92A of the workpiece 90. The clamping piece 22 is applied to the force applying plane 231 of the first cooling claw 23 and the pushing plane 251 of the throat 25. A first dodging portion 221 is formed therebetween, and the first dodging portion 221 can allow the first reverse force receiving surface 91β of the workpiece 90 to enter. The pinch 22 is in the pushing plane 251 and the second jaw 24 of the throat 25 A second dodging portion 222 is formed between the second planes 242. The second dodging portion 222 can allow the second reverse force receiving surface 92B of the workpiece 90 to enter. The first pinch 22 is at the first of the second jaws 24. A third dodging portion 223 is formed between the plane 241 and the second plane 242 of the second jaw 24, and the third dodging portion 223 can allow the third reverse force receiving surface 93B of the workpiece 90 to enter. An arc chute 27 is provided. The chute 27 is disposed on one side of the second jaw 24 relative to the wrench 26, and the chute 27 has a concave arc-shaped sliding wall 271 and a sliding wall 271. The first floor 272 and a second supporting wall 273 located below the sliding wall 271 and opposite to the first supporting wall 272. The sliding wall 271 of the sliding groove 27 has no other hole structure and presents a complete concave curved surface. Therefore, the structural strength of the second jaw 24 is ensured, so that the jaw 22 can withstand the high torque pulling operation. The center of the concave surface of the wall 271 is located in the wrench 26, so the processing of the chute 27 can be completed by only one milling cutter, and the processing is simple and fast, the cost is low, and the structural strength of the 201143991 retaining clip 22 can be confirmed. The first support wall 272 and the second support wall 273 of the member 22 are parallel to each other and have a spacing of the chute 27. The clip 22 is at the second lost pawl 24 relative to the chute 27, the first support wall 272 and the second support wall 273 The position is opened with a circular through hole 274 which is adjacent to the throat 25 and passes through the first support wall 272 and the first support wall 273 of the chute 27. The through hole 274 can be combined with a cylindrical guide φ ^ column 28 '. Both ends of the guide post 28 are respectively fixed in the through holes 274 of the first support wall 272 and the second support wall 273, so that the guide post 28 is fixed. The solid is again in the chute 27. The guide post 28 has a diameter D28. The β-rope 30 is slidably disposed on the chute 27' of the body 2 〇 22 and the β ghost can drive the workpiece 90 to rotate or to move relative to the outside of the workpiece 90. In the present embodiment, when the clamp 22 is not engaged with the workpiece 90, the α block 30 is not subjected to the elastic pushing, and the relative lept line slip relationship can be naturally generated in the chute 27. The slider 30 is substantially in the form of an arc-shaped block. The vertical slider 30 is formed on the side of the spring 30. A convex curved surface 31 is formed. The sliding surface 31 of the slider 30 is the sliding wall 271 of the sliding groove 27. The upper slide causes the slider 30 to have a relative arc slip relationship with the loader 22. The sliding surface 31 of the slider 30 does not have another hole > the same structure and presents a complete convex arc shape, thus ensuring that the structural strength of the slider 30 enables the slider 30 to withstand the high torque pulling operation. The curvature of the slip surface 31 of the β block 30 is equal to the curvature of the slip 璧271 of the chute 27, so that the slip surface 31 of the slider 30 can smoothly slide on the slide 71 of the chute 27, and, when the slider 3) When the reaction force of the work object 90 is received, since the slip of the slip plate 31 and the slip wall 271 is the same, the slip surface 201143991 can transfer the reaction force of the work object 90 to the slip wall 271 over a large area. The problem of distracting the force of the slider 30 to avoid stress concentration is also to increase the torsion force that the slider 30 can withstand when the body 20 is turned. The slider 30 has a first end 303 and a second end 304 opposite to each other, and the first end 303 of the slider 30 can flip the workpiece 90. The first end 303 of the slider 30 has a turning surface 32 protruding from the outside of the sliding slot 27, and the second end 304 of the slider 30 has a positioning surface 33 protruding from the outside of the sliding slot 27, the turning surface 32 and the positioning surface 33 is formed on a side of the slider 30 opposite to the slip surface 31, and the flap surface 32 is for rotating the workpiece 90. The turning surface 32 is remote from the throat 25 and the positioning surface 33 is adjacent to the throat 25. The positioning surface 33 can correspond to the third positive force receiving surface 93A of the workpiece 90. During the process of the workpiece 90 entering the wrench 26, the workpiece 90 can push the second end 304 of the slider 30 to make the slider The positioning surface 33 of the 30 is in surface contact with the third positive force receiving surface 93A of the workpiece 90, so that the first end 303 of the slider 30 automatically abuts against the fourth positive force receiving surface 94A of the workpiece 90. In this way, it is possible to effectively prevent the turning surface 32 of the slider 30 from coming into contact with only the single corner of the workpiece 90 at the end angle between the third positive force receiving surface 93A and the fourth positive force receiving surface 94A. When the turning operation is performed, the problem that the turning surface 32 wears the end angle of the workpiece 90 is not caused. There is an angle αΐ between the turning surface 32 and the positioning surface 33, and the angle αΐ between the turning surface 32 of the slider 30 and the positioning surface 33 is not greater than the fourth positive force receiving surface 94Α and the third forward direction of the workpiece 90. The angle α0 of the force bearing surface 93Α. The turning surface 32 of the slider 30 can correspond to the fourth positive force receiving surface 94 of the workpiece 90, and if the first end 303 of the slider 30 is subjected to the top of the workpiece 90 201143991, the block 30 will be clockwise. The direction of the first - % .-μ , & the gripper 23 is generated by the sliding movement of the slider 30 as the positioning surface 3 of the slider 30. This corresponds to the third positive fork surface 93A of the workpiece 90, and if the slider The second end 304 of the Μβ±ni卯 is subjected to the dome % of the workpiece 90, and the slider 3〇 is moved in an anti-clockwise manner until the direction of the positioning surface ^^-cooling claw 24 generates force © The 疋® 33 is in surface contact with the third positive koji y<iA of the workpiece 90, and the fourth positive Λ ^ of the crop 90 causes the slewing surface 32 to automatically abut the fourth positive force S94A. So, (four) is effective enough

Τ_工科 will not create the problem of turning the surface 32 wear and work, ^. The slider 30 has an avoiding portion 34 formed between the turning surface 32 and the positioning surface 33, and the avoiding portion 34 allows the third reverse force receiving surface 93 of the workpiece 9A to enter. A top surface 3〇1 is formed above the/month block 30, the top surface 3〇1 is in contact with the first support wall 272 of the/moon groove 27, and a bottom surface 3〇2 'bottom 302 system is formed below the slider 3〇 Contacting the second support wall 273 of the chute 27. The top surface 3〇1 and the bottom surface 302 are parallel to each other and the slider 3〇 has a height. In the case where the male and female are not discussed with the reserved tolerance, the height of the sliding 30 is equal to the spacing of the chute 27, so that the top surface 3〇1 and the bottom surface 3〇2 of the slider 3〇 can be the first of the chute 27. A support wall 272 and a second support wall 2 are vertically symmetrically supported. Since the top surface 301 and the bottom surface 302 of the slider 30 are supported by the first support wall 272 and the second support wall 273 of the chute 27 in a vertically symmetrical manner, the slider 30 will not sway when the arc is slipped in the chute 27. The problem can improve the stability of the open-end wrench 1 〇. 17 201143991 The slider 30 is further provided with a guiding groove extending through the top surface 3〇1 and the bottom surface 3〇2, the guiding groove 35 is in an arc shape, and the curvature of the guiding groove 35 is

Since the guide (4) 5 series runs through the top surface, the bottom guide groove 35 has a groove height equal to the height of the slider 3〇, and the guide groove 35 has a groove width W35, and the groove width is thrown by the guide bow groove. The large arc half field goes to the small arc half (four) turn. The groove width W35 of the guide groove 35 is equal to the diameter D28 of the guide bow&> in the case where the male and female males are reserved with tolerances. The groove height of the guide groove 35 is greater than 5 times the groove width, and it can be said that the groove width W35 of the guide groove 35 is smaller than the groove height of the groove height. In the present embodiment, the groove height of the guide bow I groove 35 is larger than twice the groove width W35, that is, the groove width W35 of the guide groove 35 is smaller than 槽·5 times the groove height.导引 The guide groove 35 is provided for guiding the main body 28 to extend therein to prevent the slider from being detached from the chute 27. Since the curvature of the sliding surface 31 of the slider 30 and the guiding groove 35 are the same as the curvature of the sliding wall 271 of the sliding groove 27, the sliding surface 31 of the slider 3〇 is on the sliding wall 271 of the sliding groove 27. When the arc slip motion is performed, a smooth relative arc slip effect can be generated between the guide groove 35 of the slider 30 and the guide post 28 in the chute 27 without interference. The guiding groove 35 has an abutting end 351 and a top end 352. The guiding post 28 is located between the abutting end 351 and the top end 352. During the process of the workpiece 9〇 entering the wrench 26, the working object 9 The second end 304' of the slider can be pushed up to make the positioning surface 33 of the slider 30 face-contact with the third positive force receiving surface 93A of the workpiece 9〇, thereby making the first end of the slider 3〇 3 Automatically abuts against the fourth positive force receiving surface 94A of the workpiece 90, and after the force applying plane 231 of the first central claw 23 abuts against the first positive force receiving surface of the workpiece 9〇8 18 201143991' A first space 36 is formed between the abutting end 351 of the guiding groove 35 of the sliding block 30 and the guiding post 28, and a second portion is formed between the top end 352 of the guiding groove 35 and the guiding post 28 of the sliding block 30.

當夾顎22扳轉工作物90使夾顎22產生彈性變形時， 本體20相對於工作物90轉動，所述第一空間36能夠於夾 顎&彈性擴張時使滑塊30的第一端303仍抵接於工作物 第四正向受力面94A ’並且使滑塊30帶動工作物9〇 轉動所述的第一空間36使滑塊30的抵接端351不會碰 到導引柱28 ’防止導引枉28扭曲變形而損壞。 當本體20反向轉動時，所述的第二空間37能夠讓滑 塊30不會帶動工作物90轉動，並且使夾顎22銜接於工作 物90的下—個扳轉位置。 進一步來說，第一空間36具有 q —空間37具有一個第二弧長AL37,導引槽35的抵接端 ^ V引柱28彼此接近時，導引槽内的第一空間 :第—弧長AL36減少，第二空間37的第二弧長顧增 :，以使扳轉面32仍然能夠抵頂於工作物9〇㈤第四正向 94A且此時疋位面33亦能夠抵接於工作物90的 第三正向受力面’以達到超高扭力之扳轉效果。 虽導引槽35的頂掣端π2與導引柱犯接近時，導引 ㈢内的第一空間36的第一弧長从36增加，第二空間 的笛勺第一弧長AL37減少’以使扳轉面32遠離1作物90 的正向又力面94A’而能夠讓夹顆22銜接於工作物90 的下一個扳轉位置。 201143991 ^第一空間36的第一弧長AL36必須大於工作物90在進 行加工時所允許產生的尺寸公差。也就是說，在不考慮工 作物90於同/規格尺寸所發生大小略有差異之尺寸公差 情況下’第一空間36的第一弧長AL36必須大於工作物9〇 的尺寸公差。如此，第一空間36能夠有效的達成讓夾顎 22彈性擴張時使滑塊30的扳轉面32仍抵接於工作物9〇 的第四正向受力面94A的效果。 更佳者，第一空間36的第一弧長AL36是大於導引槽 35槽寬W35的一半，亦即，第一空間36的第一弧長乩36 大於導引柱28直徑D28的一半。 導引槽35内未開設其他孔洞結構，有效避免應力集中 的問題，因此確保了滑塊30的結構強度，使滑塊3〇能夠 承文向扭力之扳轉工作。同時，由於滑塊3〇的滑移面31 及‘引槽35内皆未開设其他孔洞結構，故滑塊之加工 成本即可有效的降低，使得產品本身具有承受高扭力及價 格低廉的優點，可廣受產業利用。 當開口扳手10之夾顎22未銜接工作物90時，由於滑 塊30未受到彈力頂推，故滑塊30能夠自然的於滑槽27 内產生相對的弧線滑移關係。此時，導引槽35的抵接端 351或頂掣端352可能兩者都不會接觸導引柱28，或者， 導引槽35的抵接端351或頂掣端352可能有一者會鄰近或 接觸導引柱28。如圖三所示者為導引槽35的頂掣端352 與導引柱28接觸的情況。 參照圖四至圖六，為本發明開口扳手10夾韻22銜接 20 201143991 工作物90之示意圖，表示工作物9〇進入扳口 26的過程。 當開口扳手10之失韻22要銜接工作物90時，本體朝 向工作物90靠近，使工作物9〇的第二正向受力面92A與 第三正向受力面93A間的端角抵頂於滑塊30之定位面 33，並讓夾顎22的第一夾爪23之施力平面231抵接於工 作物90的第一正向受力面91A，如圖四所示。 當滑塊30第二端304的定位面33受到工作物90的抵 頂時，本體20持續朝向工作物90靠近，工作物90會推動 滑塊30的第二端，使滑塊30相對於滑槽27產生逆時針方 向的弧線滑移運動，並讓滑塊30導引槽35的抵接端351 朝向導引柱28滑移，進而使定位面33靠近工作物9〇的第 三正向受力面93A，如圖五所示。 接著本體20持續朝向工作物90靠近，如圖六所示’ 滑塊30導引槽35之抵接端351持續朝向導引柱28滑移， 直至滑塊30的定位面33抵靠於工作物90的第三正向受力 面93A形成面接觸，藉以使滑塊30的第一端303自動抵接 於工作物90的第四正向受力面94A。 本實施例中，滑塊30的扳轉面32與定位面33的炎角 αΐ等於工作物90的第四正向受力面94A與第三正向受力 面93Α的夾角αΟ，故滑塊30的定位面33抵靠於工作物 90的第三正向受力面93Α時’能夠使滑塊30的扳轉面32 自動貼合於工作物90的第四正向受力面94Α，使扳轉面32 與定位面33同時貼合於工作物90上形成兩面抵靠。 在此同時，可以看到第一空間36存在於滑塊30導引 201143991 槽35的抵接端351與導引柱28之間 ，而且，第一空間36 的第:弧長AL36大於:^作物9Q於該規格下的尺寸公差。 …當工作物90進入夾顯22之扳口 26内時，滑塊30的 定位面33被工作物90推動，使滑塊30㊣夠相對於本體 2〇產生弧線移動，直到滑塊30的第一端303接觸於工作 物9〇的第四正向受力面，可使滑塊3G第-端303的 扳轉面32自動貼合於工作物90的第四正向受力面94A，When the jaw 22 turns the workpiece 90 to elastically deform the jaw 22, the body 20 rotates relative to the workpiece 90, and the first space 36 can cause the first end of the slider 30 when the clip is elastically expanded. 303 still abuts the fourth positive force receiving surface 94A ′ of the workpiece and causes the slider 30 to drive the workpiece 9 〇 to rotate the first space 36 so that the abutting end 351 of the slider 30 does not touch the guiding column 28 'Prevents the guide 枉 28 from being distorted and damaged. When the body 20 is rotated in the reverse direction, the second space 37 enables the slider 30 to not rotate the workpiece 90, and the clip 22 is engaged with the lower-turning position of the workpiece 90. Further, the first space 36 has a q-space 37 having a second arc length AL37. When the abutting ends of the guiding grooves 35 are close to each other, the first space in the guiding groove: the first arc The length AL36 is reduced, and the second arc length of the second space 37 is increased: so that the turning surface 32 can still abut the workpiece 9〇(5) the fourth forward direction 94A and the clamping surface 33 can also abut The third positive force receiving surface of the workpiece 90 is to achieve an ultra-high torque pulling effect. When the top end π2 of the guiding groove 35 is close to the guiding column, the first arc length of the first space 36 in the guiding (3) is increased from 36, and the first arc length AL37 of the second space is decreased. Keeping the turning surface 32 away from the positive force surface 94A' of the 1 crop 90 enables the clip 22 to engage the next pivoting position of the workpiece 90. 201143991 The first arc length AL36 of the first space 36 must be greater than the dimensional tolerances allowed for the workpiece 90 to be processed. That is, the first arc length AL36 of the first space 36 must be greater than the dimensional tolerance of the workpiece 9〇 without considering the dimensional tolerance of the crop 90 in a slightly different size from the same size/size. Thus, the first space 36 can effectively achieve the effect of causing the flap surface 32 of the slider 30 to abut against the fourth positive force receiving surface 94A of the workpiece 9A when the clip 22 is elastically expanded. More preferably, the first arc length AL36 of the first space 36 is greater than half the groove width W35 of the guide groove 35, that is, the first arc length 乩36 of the first space 36 is greater than half the diameter D28 of the guide post 28. No other hole structure is formed in the guiding groove 35, thereby effectively avoiding the problem of stress concentration, thereby ensuring the structural strength of the slider 30, so that the slider 3 can be rotated by the torsion force. At the same time, since the sliding surface 31 of the slider 3 and the groove 33 have no other hole structure, the processing cost of the slider can be effectively reduced, so that the product itself has the advantages of high torque and low price. Can be widely used by the industry. When the jaws 22 of the open-end wrench 10 are not engaged with the workpiece 90, since the slider 30 is not pushed by the elastic force, the slider 30 can naturally generate a relative arc-slip relationship in the chute 27. At this time, the abutting end 351 or the top end 352 of the guiding groove 35 may not contact the guiding post 28, or the abutting end 351 or the top end 352 of the guiding groove 35 may be adjacent to one another. Or contact the guide post 28. As shown in FIG. 3, the top end 352 of the guiding groove 35 is in contact with the guiding post 28. Referring to FIG. 4 to FIG. 6 , a schematic diagram of the work tool 90 of the open end wrench 10 of the present invention is shown in FIG. 4 to FIG. 6 , which shows the process of the workpiece 9 〇 entering the trigger 26 . When the rhyme 22 of the open-end wrench 10 is to be engaged with the work object 90, the body approaches the work object 90, and the end angle between the second positive force-receiving surface 92A of the work object 9〇 and the third positive force-receiving surface 93A is abutted. It is placed on the positioning surface 33 of the slider 30, and the force applying plane 231 of the first jaw 23 of the clamp 22 abuts against the first positive force receiving surface 91A of the workpiece 90, as shown in FIG. When the positioning surface 33 of the second end 304 of the slider 30 is abutted by the workpiece 90, the body 20 continues to approach the workpiece 90, and the workpiece 90 pushes the second end of the slider 30 to make the slider 30 relatively slippery. The groove 27 generates a counter-clockwise arc sliding movement, and causes the abutting end 351 of the sliding groove 30 of the slider 30 to slide toward the guiding post 28, thereby bringing the positioning surface 33 closer to the third positive direction of the workpiece 9〇. Force surface 93A, as shown in Figure 5. Then, the body 20 continues to approach the workpiece 90, as shown in FIG. 6 'the abutting end 351 of the slider 30 guiding groove 35 continues to slide toward the guiding post 28 until the positioning surface 33 of the slider 30 abuts against the workpiece The third positive force receiving surface 93A of 90 forms a surface contact, whereby the first end 303 of the slider 30 automatically abuts against the fourth positive force receiving surface 94A of the workpiece 90. In this embodiment, the yoke angle α ΐ of the turning surface 32 of the slider 30 and the positioning surface 33 is equal to the angle α Ο between the fourth positive force receiving surface 94A of the workpiece 90 and the third positive force receiving surface 93 Ο, so the slider When the positioning surface 33 of the 30 abuts against the third positive force receiving surface 93 of the workpiece 90, the rotating surface 32 of the slider 30 can be automatically attached to the fourth positive force receiving surface 94 of the workpiece 90, so that The turning surface 32 and the positioning surface 33 are simultaneously attached to the workpiece 90 to form a two-sided abutment. At the same time, it can be seen that the first space 36 exists between the abutting end 351 of the slot 30 of the 201143991 slot 35 and the guiding post 28, and the arc length AL36 of the first space 36 is greater than: 9Q dimensional tolerances under this specification. When the workpiece 90 enters the trigger 26 of the clip 22, the positioning surface 33 of the slider 30 is pushed by the workpiece 90, causing the slider 30 to move in an arc relative to the body 2〇 until the slider 30 is The one end 303 is in contact with the fourth positive force receiving surface of the workpiece 9〇, so that the turning surface 32 of the first end 303 of the slider 3G can be automatically attached to the fourth positive force receiving surface 94A of the workpiece 90,
形成面接觸。由於工作物9〇的第四正向受力面94A與第一 正向文力面91A彼此平行，故滑塊30的扳轉面32大致上 與第一夹爪23的施力平面231平行。 藉由滑塊30的定位面33被工作物90推抵，滑塊3〇 第一端303自動抵於工作物90的第四正向受力面94八，且 扳轉面32自動貼合第四正向受力面94A ’使滑塊3〇第— 柒303與第一夾爪23的施力平面231可有效施力於工作物 90相對的兩面，如此，即能夠有效的防止滑塊30的扳轉 面32僅單點接觸於工作物90的第三正向受力面93A與第 正向支力面94A之間的端角處的狀况發生，當進行板轉 作業時就不會造成扳轉面32磨損工作物90端角的問題， 以達到高扭力扳轉的效果。 參照圖七，為本發明開口扳手1〇沿夾顎22朝第一失 爪23方向扳轉以帶動工作物轉動之狀態圖。 使用者可沿失顎22朝第一夾爪23方向扳動握持部 21，使夾顎22以工作物90的圓心轉動。使用者的施力經 由第一夾爪23的施力平面231傳遞給工作物90的第一正 22 201143991 向受力面91A，同時使用者的施力亦經由滑塊30的扳轉面 32傳遞給工作物90的第四正向受力面94A，如此即可使工 作物90跟著夾顎22轉動。於前述操作過程中，滑塊30 的定位面33抵接於工作物90的第三正向受力面93A，具 有輔助帶動工作物90轉動的效果。 由於第一夹爪23係一體成型的設於夾顎22，故第一 夾爪23的施力平面231能夠有效的承受工作物90第一正Form surface contact. Since the fourth positive force receiving surface 94A of the workpiece 9〇 and the first forward force surface 91A are parallel to each other, the turning surface 32 of the slider 30 is substantially parallel to the biasing plane 231 of the first jaw 23. When the positioning surface 33 of the slider 30 is pushed by the workpiece 90, the first end 303 of the slider 3 is automatically pressed against the fourth positive force receiving surface 94 of the workpiece 90, and the turning surface 32 is automatically fitted. The four positive force receiving surfaces 94A' enable the sliders 3 〇 — 303 and the urging plane 231 of the first jaws 23 to effectively apply the opposite sides of the workpiece 90, so that the slider 30 can be effectively prevented. The turning surface 32 only contacts the end point between the third positive force receiving surface 93A and the first positive bearing surface 94A of the workpiece 90 at a single point, and does not occur when the plate turning operation is performed. The problem that the turning surface 32 wears the end angle of the workpiece 90 is achieved to achieve the effect of high torque turning. Referring to Figure 7, the open end wrench 1 of the present invention is rotated along the clamp 22 toward the first lost claw 23 to drive the workpiece to rotate. The user can pull the grip portion 21 toward the first jaw 23 along the failing 22 to rotate the jaw 22 at the center of the workpiece 90. The urging force of the user is transmitted to the first positive 22 201143991 of the workpiece 90 via the urging plane 231 of the first jaw 23 to the force receiving surface 91A, and the urging force of the user is also transmitted via the slewing surface 32 of the slider 30. The fourth positive force receiving surface 94A of the workpiece 90 is applied such that the workpiece 90 rotates following the jaw 22. During the foregoing operation, the positioning surface 33 of the slider 30 abuts against the third positive force receiving surface 93A of the workpiece 90, and has the effect of assisting the rotation of the workpiece 90. Since the first jaw 23 is integrally formed on the clamp 22, the force applying plane 231 of the first jaw 23 can effectively withstand the first positive work 90
向受力面91A的反作用力。又由於第二夾爪24係一體成型 的設於夾顎22，且滑塊30的滑移面31與滑槽27的滑移 壁271皆未開設其他孔洞，滑塊的滑移面3ι與滑槽 的滑移壁271曲率相同，是面與面的接觸，故滑塊3〇的扳 轉面32能夠有效的承受工作物9〇第四正向受力面94八的 反作用力，因此，本發明的開口扳手1〇將能夠承受高扭力 之扳轉作業。 ---叫T/又山,p切ου惟夺氏，濟 塊30第-端303自動抵於工作物90的第四正向受力面 训Μ且扳轉面32自動貼合第四正向受力面94Α，使滑塊 第-端303與第—夾爪23的施力平面231可有效施力 於工作物90相對的兩面，以達到高扭力扳轉的效果。 ⑽估2使用者是透過本體2〇的握持部21進行施力，假 二Γ的施力固定不變，本體2〇的力臂長度固定不變: 麼本體20的順時針力矩就能夠帶動工作The reaction force to the force receiving surface 91A. Moreover, since the second jaw 24 is integrally formed on the clamping jaw 22, and the sliding surface 31 of the slider 30 and the sliding wall 271 of the sliding slot 27 are not provided with other holes, the sliding surface of the slider is 3π and slippery. The sliding wall 271 of the groove has the same curvature and is a surface-to-surface contact, so that the turning surface 32 of the slider 3 can effectively withstand the reaction force of the workpiece 9 〇 the fourth positive force receiving surface 94, therefore, The open-end wrench 1〇 of the invention will be able to withstand the high torque pulling operation. --- Call T / Yamayama, p cut ου only to win, the block 30 first end 303 automatically against the work object 90 of the fourth positive force surface training and the turning surface 32 automatically fit the fourth positive The force receiving surface 94 is so that the first end 303 of the slider and the urging plane 231 of the first jaw 23 can effectively apply to the opposite sides of the workpiece 90 to achieve a high torque pulling effect. (10) It is estimated that the user applies the force through the grip portion 21 of the main body 2, the biasing force of the false second jaw is fixed, and the length of the arm of the main body 2〇 is fixed: the clockwise moment of the body 20 can be driven. jobs

The counterclockwise moment is equal to the clockwise moment of the body 2〇. J 23 201143991 Refer to Figure VIII. In order to make the 9G lock of the crop crop tighter, hold the body 20 (4) and then extend an extension tube to extend the force. The length of the arm enables the dragon to produce a large torque effect in the case of phase force. The thrust plane 251 of the throat 25 has a refresh angle of -100 degrees between the force applying plane 231 of the first jaw 23, and the thrust plane condition of the throat 25 corresponds to the second forward direction of the workpiece 90. The force receiving surface 92A has a spacing D between the pushing plane 251 and the second positive force receiving surface 92A of the workpiece 90, so that the working object 90 also has a space moving toward the inside of the wrench 26, and the missing piece 22 The pushing surface 251 and the second positive force receiving surface 92 of the workpiece 90 have a spacing D and are not in contact. When the user applies force to lock the work object 90 to a certain extent, the reaction force applied by the workpiece 90 to the clamp 22 becomes large, causing the clamp 22 to begin to elastically deform, and the work object 90 is no longer followed by the open-end wrench 1 The crucible rotates such that the body 20 gradually rotates clockwise relative to the workpiece 9. The squeezing of the workpiece 90 causes the yoke 22 to be elastically deformed, which causes the yoke to become larger. The distance between the thrust plane 251 and the second positive force receiving surface 92A of the workpiece 90 is D'. After the wrench 26 of the magazine 22 is deformed, the workpiece 9〇 will move inwardly toward the pushing plane 251. At this time, the first space 滑块 of the slider 3〇 can cause the positioning surface 33 of the slider 30 to receive the workpiece 9 The 〇 push generates an arc movement such that the slewing surface 32 of the first end 303 of the slider 30 still abuts against the fourth positive force receiving surface 94A of the workpiece 90 and maintains the effect of the surface contact. The first arc length of the first space 36 is gradually reduced by 36. Since the clamping angle 22 is elastically expanded, the opening angle is gradually increased, so that the stress of the clip f贞22 in the elastic deformation is gradually increased, and the resistance of the pin is changed to 24 201143991 liters/until the stress of the clipping 22 resisting deformation is greater than the working object. When the 90 is applied to the reaction force of the clamp 22, the clamp 22 is no longer elastically deformed. At this time, the slider 30 can again be driven by the pinch 22 to allow the open-end wrench 1 to perform the ultra-high torque turning operation. Thereafter, the user can move in the direction of the first jaw 23 along the jaw 22 to rotate the jaw 22 at the center of the workpiece 9〇. The urging force of the user is transmitted to the first positive force receiving surface 91A of the workpiece 90 via the urging plane 231 of the first jaw 23, and the user's urging force is also transmitted to the workpiece 9 via the turning surface of the slider. The fourth positive force receiving surface 94A of the crucible, so that the workpiece 90 continues to rotate along with the gripper 22, and the ultra-high torque is turned. Finally, until the work item 90 is locked. During the foregoing operation, the pushing plane 251 of the operator's throat 25 abuts against the second positive force receiving surface 92A of the workpiece 9〇, and also has the effect of assisting the rotation of the workpiece 9〇. Referring to FIG. 9 and FIG. 10, when the folder 22 is disengaged relative to the workpiece 9 ,, the turning surface 32 of the slider 30 is received by the workpiece 9 〇 the fourth positive force receiving surface 9 from the top, second The space 37 can cause the slider 30 to have an arc-slip relationship with respect to the body 2 () in the chute 27, and the slider slides toward the first jaw 23 of the clamp η, and the first space 36 in the guide groove 35 The first arc long leg = the force to the mouth 'the second arc length AL37 of the second space 37 is reduced, so that the turning surface 3 days 2 away from the workpiece 90 the fourth positive force receiving surface 94A 'can make the slider 3〇 will not drive the work 9Q rotation, and the clamp 22 will be connected to the next turning position of the crop. - Referring to Figure 10 -, two embodiments of the open-ended wrench of the instaltable screw member of the present invention are shown. The present embodiment is the same as the first embodiment of the first embodiment 25 201143991, the difference is that the angle α 1 between the turning surface 32 of the slider 30 and the positioning surface 33 is smaller than the fourth positive force receiving surface 94 of the workpiece 90. The angle α〇 of the third positive force receiving surface 93Α. Further, the angle α 1 between the turning surface 32 of the slider 30 and the positioning surface 33 is less than —-eighteen degrees. When the clamping jaw 22 engages the workpiece 90 and the workpiece 90 is not turned over, the positioning surface 33 of the slider 30 abuts against the third positive force receiving surface 93 of the workpiece 90 to form a surface contact, so that the slider 30 is The one end 303 is automatically abutted against the fourth positive force receiving surface 94 of the workpiece 90. At this time, the angle between the turning surface 32 of the slider 30 and the fourth positive force receiving surface 94 of the workpiece 90 is greater than The two-time backup angle is Θ. That is, the angle between the turning surface 32 of the slider 30 and the positioning surface 33 is less than one hundred and eighteen degrees. Thus, when the clamp 22 is elastically expanded, the backup angle 0 allows the body 20 and the slider 30 to gradually rotate clockwise relative to the workpiece, so that the trigger surface 32 of the slider 30 abuts against the fourth object of the workpiece. The positive force receiving surface 94 is so that the turning surface 32 and the fourth positive force receiving surface 94 are in surface contact, and the high torque plate rotating effect can also be achieved. Referring to FIG. 12, which is an rth embodiment of an open-end wrench for an anastomotic screw according to the present invention, the embodiment is substantially the same as the first embodiment described above, and the difference is that the open-end wrench 1 is disposed on the body 2 and the slider. A resilient device 40 is provided between the 30s to enable the slider 30 to automatically return to its original position. The two ends of the elastic device 40 are respectively abutted between the guide post 28 and the top end 352 of the guide groove ′ to enable the slider 30 to automatically return to the original position. When the missing object 22 is not engaged with the workpiece 90, the slider 30 is pushed by the elastic means so that the abutting end 351 of the guiding groove 35 comes into contact with the guiding post 28. 26 201143991 Referring to Figures 13 through 15, a schematic view of the opening wrench 10 for placing the workpiece 90 into the trigger 26 is shown in the third embodiment of the present invention. When the fault 22 is to be connected to the workpiece 9 ,, the body 2 靠近 approaches the workpiece 90, and the workpiece 90 first pushes the third end 303 of the slider 3 , to make the slider 30 clockwise with respect to the chute 27 The arc sliding motion of the direction 'remotes the abutting end 351 of the slider 30 guiding groove 35 away from the guiding jaw 28. At the same time, the biasing plane 231 of the first jaw 23 of the jaw 22 abuts against the first positive force receiving surface 91A of the workpiece 90.
