It will not be ground into the manual. [Prior Art] Press the '-hand tool The design orientation, in addition to the normal, new nut plate rotation lock, in the direction of the sigh, in recent years, also has the nut angle damage, that is, the nut angle is rounded abnormal __ 'unloading composite guide design , in which the normal and the nut angle of the nut is rounded, the abnormal lock of the nut is turned, and the related case, such as the Dina 美国 US patent case, the previous case is driven by the two 颚 之There are two parts on the surface, each of which forms a roughened end, and the other non-roughened end of the thickened end of the Heilongjiang end is more complex, and is diagonally diagonally thin. Department, the rough end of the fine knot design, its main disadvantage is that when the wrench is © and clockwise, although it can reach the end, but can only borrow The groove only protects the nut angle, and the other screw will be worn by the non-end. When the wrench is turned on the front and counterclockwise, it can be loosened and unloaded, but due to the increased frictional design, Although it can effectively achieve the effect of occlusal and rounded nut being occluded and disassembled, but also because the bite force is too large and the dent design is often caused by normal, the structure of the cap is damaged, that is, the so-called burr phenomenon occurs. The angled round nut, the light open-end wrench is loosened to the wire, and the hand is easy to smear when the hand is taken, causing the hand to stab, and the π wrench is convenient for both front and back. Sexuality, when the front case wrench is reversed and clockwise, although the locking function can be achieved, but because the two stress points are at the end, the normal, new _ lost edge causes structural damage or the corner is rounded' When the wrench is reversed and reversed by the clock, although it can be loosened and unloaded, but because the two stress points are unroughened, the angled round nut can not be occluded and disassembled. Design of the clamp structure of the old nut with normal, new and angled honing Not very ideal. And the related examples of the above-mentioned hand tool clip structure are the same or similar, such as the US Patent No. _9778, No. 5148726, No. 5117714, No. i7i, and No. 6154414, etc. The side will be bitten to produce a burr, or the angled round nut can not be bitten and disassembled, or the corner of the new nut is not damaged by the 蒦 蒦 蒦 will be ground. For example, in the U.S. Patent Nos. 5,406,868 and 5,381,710, the opposite side of the two jaws of the open-end wrench forms an opposite arc cam, and the front and rear of the tenon are curved and concave curved surface design, although the above-mentioned nut is not damaged. Phenomenon, but the structure of the open plate hand grip can not be locked or unloaded for the angled round nut. When encountering the angled round nut, you need to carry a special hand tool, such as Universal shot (1 magnetic 钿plier), the practical aspects are relatively insufficient. The Republic of China Patent Announcement No. 381525, the name of the anti-slip open-end wrench structure that can be used to pull the rounding screw, the scales should be divided into two parts - the convex and the two flat teeth - although it is for the wrench (four) honing __ The open-end wrench is designed, but when the plate is turned into a normal nut, the two opposite corners of the Cong being forced to contact with the tenon and the flat (four) sides are subject to wear and tear, and the structure of the prosthetic angle is destroyed. Also, the Republic of China Patent Bulletin No. 524181, the name of which is applicable to the improvement of the nip structure of the wear nut. The patent mainly forms a concave surface by the two convex abutting faces at the open σ end, and is composed of _ three faces. - The cost of the tool is high, and the production cost is high. Because of the clamping between the two convex-toothed napkins - the concave surface, the abutting points of the two convex abutting surfaces and the nut are bound to be farther away from the center points of the nut side. When the wrench is pulled clockwise, for example, the thirteenth figure of the patent 'wrench touch _ two force points will fall below the right side clamp 4 of the wrench, the convex side of the inner side, and the upper side of the upper part of the wrench, On the outer convex surface, the line connecting the two points of force is inclined diagonally. When the counterclockwise plate is moved, the size of the open end of the SI wrench is (4) large _ bribe size, so the convex surface will be After sliding a certain limb, it only touches the Qing (4) surface. Because of this design, the convex surface to the side of the nut must be green near the lion, and it is easy to wear to the corner of each nut and produce a nut angle. The structure is broken. In addition, the tenth figure of the patent is a flange between the two convex abutting faces, and the flange Set to a sharp tooth design, e can reach the angle of the honing round nut is occluded and disassembled 'but it is also caused by the bite flange tooth design' to cause structural damage, resulting in burrs The situation. For the design of the existing hand-held armor open or Lai drive head clamp structure, the nut lock and unloading function without both angle and rounding, and the prevention of the nut clip edge structure are 1322063. The main purpose of the present invention is to provide a • The hand tool clamp part of the nut does not damage the nut clip edge structure. Thanks to the old nut that has been used for the production of the brand for ten years, the nut can be used, and the clamp of the tool can be used. [Invention] A lack of normal damage, the inventors of the present invention have succeeded in developing a hand tool holder for a new and new hand-loading function that has both a protective structure. Another object of the present invention is Providing a non-normal rounding nut locking and unloading process that is both versatile and versatile, and the masquerading of the target is mainly used in the lyrics of the lyrics, or the paste type The clamping surface of the joint of the crane head includes a biting area and a non-biting area, and the nip area is used for the occlusal workpiece, and the center of the nip is formed into a bulge, and the end of the bulge is provided with a nip groove , the bite_ is attached to the end of the tenon and has an abutment angle And the extension groove of the outer portion of the bite groove is formed to form a function of locking the normal and abnormal nut, and the novel hand tool which does not damage the nut edge structure during the locking process. [Embodiment] As shown in the first and first figures, the present invention relates to a clip of a hand tool. The structure of the clip portion is as shown in the figure.
