Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to an improved design of a six-tooth L-wrench, in particular to the spherical drive head of the six-tooth L-wrench and its neck system It has six convex teeth that are equiangularly distributed and extend for a long curved arc, so it can achieve the purpose of multi-angle insertion operation. [Prior art] There are many types of socket nuts, especially the shapes of the socket grooves. Therefore, the shape of the driving head of the L-shaped wrench that must be used must also match each other to make the drive. The head can be inserted into the groove of the socket to provide nut locking or loosening. For the six-tooth socket socket of the conventional type shown in Figure 6, the socket groove has six tooth-shaped inner grooves. When locking or loosening is applied, an L-shaped wrench with six matching corresponding teeth is required to form a driving head. In this conventional six-tooth type L-shaped wrench, the driving head can only be inserted into the six teeth vertically. The shape of the socket recess can only be locked and unloaded. Therefore, if there is a blocking object above the six-tooth socket nut (for example, the socket nut is often locked and located under the eaves), It is known that the six-tooth type L-shaped wrench cannot be inserted vertically. Since it can only be used at a single angle in a vertical manner, the use operation is inevitably restricted. Occasionally, it is impossible to smoothly engage in the nut lock unloading, which is still unreasonable. Convenience. [New content] The main purpose of this creation is to provide a six-tooth L-wrench design that can be inserted at multiple angles, but the six-tooth L-wrench ball drive head and its neck structure have six The convex teeth that are equiangularly distributed and extend in a long curved arc, and each convex tooth is provided with a chamfered portion at the end. The six concaves are used.

Creation instructions (2) The arc-shaped extended teeth make the ball-shaped driving head of the L-shaped wrench not only insert the six-tooth socket nut vertically, especially by using the special neck design. The multi-angle oblique insertion method enters the tooth-shaped inner groove, so it can provide various oblique insertion angles for force to pull the nut and engage in locking or loosening work. The overall use is more reasonable and convenient, so it is not covered by the obstructing objects. Restrictions give it more use of operating functions. [Embodiment] The structure and other functions and purposes of this creation are described in detail in the embodiment of the drawings as follows: As shown in the first to third figures, this creation is a "six-tooth L-shaped wrench that can be inserted at multiple angles" ”Design, one or both ends 4 of the L-shaped wrench 1 is provided with a spherical driving head 11, and the spherical driving head 11 has a narrow and elongated neck, which is composed of a six-tooth socket nut 2 The hexagonal inner groove 2 0 1 system of 0 (as shown in the sixth figure) corresponds to each other, but the spherical driving head 1 1 and its neck system have six equiangular distributions and long curved arcs. The extended convex teeth 12 are provided with chamfered portions 13 at the ends of the convex teeth 12 to form a spherical driving head 1 1. The spherical driving head 11 of the six-tooth L-shaped wrench is Form a narrow neck shape with narrow curved arc. The six-tooth L-shaped wrench 1 that can be inserted at multiple angles is used in this work. In normal use (as shown in the fourth figure), except that the six teeth of the six-tooth socket nut 20 can be inserted in a vertical direction. In addition to the inner slot 2 0 1, it can be inserted into the hexagonal slot 2 0 1 (as shown in the fifth figure) with an oblique insertion method of more angles | degrees, so it can provide various oblique insertion angles for force pull. Move the nut 20, and then engage in locking or loosening work.
第6頁 M265165 四、創作說明（3) 上述本創作之斜插使用形態，主要係針對六齒型L形 扳手1無法以垂直方向插入使用時之所為功能應變改良， 例如當六齒承窩螺帽2 0上方設有如簷片等遮擋物件時，即 可改採斜插角度進入六齒形内槽2 0 1 ，利用球形驅動頭部 1 1所設呈狹長彎弧内縮的頸部可在六齒形内槽2 0 1 任意斜 插抵持，藉此提供較為廣角的適用範圍，以求閃避遮擋物 件，並仍提供正常之鎖合或鬆卸操作功能，故本創作於整 體使用上並不會受限於垂直單一角度的操作模式，具有不 同多向角度均適合插置操作的變化功效。 再言，上述六齒型L形扳手1 ，其桿體可採六角桿、 圓桿或其他形狀桿體，並無限制必要。 綜上所述，誠可見本創作所為可多角度插置之六齒型 L形扳手設計，其整體組成形態確有別於習知六齒型L形 扳手，且操作使用已具有進步功效，理應符合新穎實用要 件，謹依法申請新型，惟祈 鈞局依法賜准專利為禱。Page 6 M265165 IV. Creation instructions (3) The above-mentioned oblique insertion use form is mainly for the improvement of the functional strain when the six-tooth type L-shaped wrench 1 cannot be inserted in the vertical direction, such as when the six-tooth socket screw When there are obstructions such as eaves above the cap 2 0, you can change the angle of oblique insertion into the six-toothed inner groove 2 0 1, and use the ball to drive the neck 1 which is set in a narrow curved arc. The six-toothed inner groove 2 0 1 can be inserted obliquely and arbitrarily, so as to provide a wider range of application scope, in order to avoid obstructing objects, and still provide normal locking or loosening operation functions, so this creation is based on the overall use and Will not be limited to the vertical single-angle operation mode, with different multi-directional angles are suitable for the changing effect of the insertion operation. In addition, the six-toothed L-shaped wrench 1 may be a hexagonal rod, a round rod, or other shape rod body, and it is not necessary to limit it. In summary, it can be seen that the design of this creation is a six-tooth type L-shaped wrench that can be inserted at multiple angles. Its overall composition and shape are indeed different from those of the conventional six-tooth type L-shaped wrench. In line with the novel and practical requirements, I would like to apply for a new model in accordance with the law, but I pray that the Bureau will grant a quasi-patent in accordance with the law.
