New description: [New technical field] One-way clamping opening This creation involves the field of wrenches, especially _ mouth wrenches. [Prior Art] The early open-end wrench has a - grip 'grip - the end is divided into two clips. 'The two clips form an opening at a predetermined distance apart, and the fastener (such as a bolt or nut) is loosened or Lock the job. During use, the two jaws are wrapped around the fasteners and the opposite sides are rotated by an angle, and then the fasteners are reversely rotated and then placed on the opposite side of the fasteners, and the action of the cycle is repeated, which increases the inconvenience of the tightening operation. ° The recent open-end wrenches, such as the US 3,695,125, 3,709,073 and 4,158,975 patents, add a movable block to the fastener, and create a one-way clamping function for the fastener. The wrench drive fastener unidirectional rotation 'reverse rotation does not work. A common problem with the construction of these open-end wrenches is that the movable block is between two sheets that are fastened to the clips, which not only weakens the strength of the jaw structure, but also makes the production process quite cumbersome. & There are also some active blocks, such as the U.S. Patent No. 7,878,095, which discloses that the Swing Member 'the thickness is equal to the Jaw'. The thin convex shape of the Convex Arcuate Surface is formed by a radial direction. First Peripheral Protrusion, inserted into a first Slot that is recessed inside the 颚 clip, with a pin that is forced against the lost pin, passing through a curved hole that runs through the flange (Arcuate Hollow) Groove), limit the D-shaped block not 3 v vM439545 have to leave the folder. In this way, directly increasing the strength of the truss structure, but also increasing the difficulty of making the inner surface into the arc groove. In particular, in the '095 patent, it is emphasized that the D-shaped block has a center of the convex curvature of the plan, and a height difference Η from the center of the circle to a bottom surface between the D-shaped block and the opposite-side clip, and a D-shaped block and the opposite side The width S of the work area between the jaws should satisfy the 29% S<H<58% S relationship in an attempt to lock the range of height drops. However, the position of the center of the circle is difficult to judge, resulting in a ambiguous range of altitude differences. Even if the D-shaped block slides along the arc groove, it does not help because of the range of the φ difference, because the amplitude of the movement of the D-block is determined by the blocking action of the closed end of the curved hole on the pin. In addition, the addition of a spring (Returning Device) inside the arc slot, while pushing the D-shaped block to homing, will hinder the movement of the D-block, and the production cost is increased, which is not conducive to market competition. Therefore, how to provide an excellent one-way open end wrench has become an urgent problem to be solved in this creation. [New content] · In view of this, the creator has in-depth discussion of the problems of prior art. With years of experience in R&D and manufacturing of related industries, he actively sought solutions and finally successfully developed a one-way clamping open-end wrench. To improve the problem of custom creation. One of the main purposes of this creation is to use the external combination structure to solve the inconvenience of the conventional D-shaped block placed inside the clamp and reduce the difficulty in making the opening wrench. One of the main purposes of this creation is to limit the D-shaped block in the 颚 position 4 M439545

At the same time, the cost of production is reduced because there is no spring, which enhances market competitiveness. In particular, when the back surface of the flat portion is blocked by the first blocking surface, the front surface of the flat portion and the first plane are maintained in a staggered state, which facilitates the work of the wrench. When the back surface of the flat portion is blocked by the second blocking surface, the flat portion is maintained in a parallel state with the first plane, which facilitates the tightening work for the one-way clamping. The following is a detailed description of the purpose, structure, and characteristics of the related embodiments based on the drawings. It is believed that the techniques, means, and functions employed in the present invention can be understood in detail. 5

The inner surface has a second-curved surface 23, Angle 24 face I: Located at the root of the first jaw 2 ' 'pass--arc turn ^ mountain connection - one of the two ends of the recess 25 of the brother. The first concave portion 25 is caught in the middle portion of the generous end 12. The second surface of the 30 clip 30 has a second plane Μ, the second plane ”": at the first plane 21 and adjacent to a second recess 32. The second recess is made of a 3G root portion, and the ridge is raised at the head end 12 The connecting surface 33 is connected to the other end of the first concave portion 25. In addition, a first curved surface 22 and a curved surface 23 are connected to each other, and a curved surface 26' of the first curved surface 26 protrudes toward the second clamp 30. 40. The thickness of the support portion is thinner than the first central portion (9), two figures; the height difference is formed longitudinally. The support portion is formed at an angle according to the angle-苐-feeding surface 41 and the second blocking surface 42. A second curved surface 43 is adjacent between the faces 41 and 42. y, in conjunction with Fig. 2, the D-shaped block 6〇 is viewed as a rectangular front surface of a flat portion 61 as a third flat surface 62. The restriction portion distinguishes the first restriction portion and the second clamp portion 65' from each other to be connected to the length i corresponding to the flat portion 61, and an If system 64, 65 root portion and a raised portion in the flat portion 61. The two convex surfaces 63 of the back surface are connected. The periphery of each of the restricting portions 64, 65 forms a --convex surface 66, and penetrates adjacent to the first convex surface % One hole 67. The ground is dark ^^^, I believe that the tree of the wrench 1G should have a preliminary ', then, according to Figure 3, the connection relationship is detailed: = the spacing of the parts 64, 65 is greater than the thickness of the support 4 () = branch _ 40 while maintaining mutual side-by-side relationship. The two limiting portions, the surface is flush with the first jaw 2'', and the D-shaped block 6G of the sleeve portion 40 is connected to the first clip 2 by a coupling mechanism 5 () At this point, the two convex faces 66 fit the first curved surface %, while the second convex face, the younger face 43 maintains the fit relationship 'allows the D-shaped block to swing back and forth relative to the support 4 40. * In this embodiment, the joint The mechanism 50 refers to a pin 51 disk 1 = ^ TMG clear hole 52 ° _51 length is larger than the arc ice, the middle portion of the position into the arc hole 52, with the end portion = 52 is forced to the corresponding a hole member of the restricting portion (4); preventing the D-shaped block 6〇 from being separated from the supporting portion 4〇. The aperture between the curved hole 52 5^ and the second curved surface 43 is larger than the pin north of the D-shaped block 60 relative to the supporting portion 4〇 swinging, the flat portion η moon surface resists the first blocking surface 41 and the second blocking surface 42 to limit the swing range of the d-shaped block 60. The two blocking surfaces ^ angle range At 120. ~ 150. The door is at an angle of Θ, πη.# η. Since the third plane 62 is, the D-shaped block 60 swings back and forth between 30.~6〇. When used, the wrench 1〇 The third plane 62 of the D-shaped block 60 is flattened by the opening 14 between the two jaws 2〇 and 3〇 through the outside of a fastener 70: the BC side around the fastener 70 is engaged with the second jaw 3〇 The second plane 31 is in parallel contact with the opposite EF edge to collectively clamp the periphery of the fastening 70. In Fig. 4, the fastener 7 触 touches the first recess 25 at a D angle, and the flat portion 61 is interposed between the second blocking surface 42 and the BC. Between the sides, the torque is applied to the 0th angle beyond the second convex surface 63, and the D-shaped block 60 is not caused to rotate. At the same time, the second jaw 30 is twisted in the second plane to perform the tightening operation. ί角ΠΘ Figure 5 shows that when the grip is rotated in the reverse direction of the arrow, the first first-grain surface 22 does not interfere with the ^, providing the space required for the wrench iq to rotate around the tight member 70, so that the second clamp 30 The second plane 31 contacts the E angle. The D-shaped block 6 is flexibly swayed along the B C side of the fastener 70 to partially pass the B angle, leaving the first recess 25 away from the D corner. Since the flat portion 61 f is blocked by the first blocking surface 4, the first flat surface 21 is maintained in a staggered state to facilitate the wrench 1. Fig. 6 shows that the grip 11 continues to rotate in the direction of the arrow. The third flattened the fastener _ angle so that the d-shaped block is facing each other. "0 slight swing. At this point, the second jaw 30 aligns the DE side of the touch fastener 70 with the second plane 31. Λ Figure 7 shows that the B angle of the fastener 70 deviates from the third plane so that the center material pushes (four) 阙 6G swings, and the second resistive surface 42 is flattened, so that the third plane heart: = + face 2! ❼ contact AB On the side, it is convenient for the user to choose to perform one-way 、, the fc tight operation, or to continuously rotate a certain angle. σ M439545 According to the above structure, this creation—shows, for the support department: 介:第=实: two sides such as the 42nd angle object, the phase object (four) block—the figure D block 80 is in the first, The first _ = open side.
