Description

螺絲screw

本發明是有關於一種螺攻元件，特別是指一種螺絲。The invention relates to a screw tapping element, in particular to a screw.

參閱圖1，為一現有的螺絲1，包含一螺頭11、一自該螺頭11沿一軸向延伸的桿身12，及一個一體連接於該桿身12相反於該螺頭11之一端的鑽尾13。該桿身12包括一呈螺旋環繞的螺牙121，及至少一凹設且斜向延伸的排屑槽122。當該螺絲1藉由該鑽尾13而執行鑽攻工件時，隨著該螺牙121逐漸螺入該鑽尾13於工件上鑽出的孔洞，使工件產生的殘屑將經由該至少一排屑槽122逐漸排出，避免殘屑累積於該螺牙121及該鑽尾13之間而影響鑽攻。Referring to Fig. 1, it is an existing screw 1, comprising a screw head 11, a shaft 12 extending axially from the screw head 11, and an end integrally connected to the shaft 12 opposite to the screw head 11 13 of drill tails. The shaft 12 includes a spiral thread 121 and at least one recessed chip removal groove 122 extending obliquely. When the screw 1 is used to drill the workpiece by the drill tail 13, as the thread 121 is gradually screwed into the hole drilled by the drill tail 13 on the workpiece, the debris generated by the workpiece will pass through the at least one row The chip flutes 122 are gradually discharged to prevent debris from accumulating between the screw thread 121 and the drill tail 13 and affecting drilling.

螺攻元件的適用範疇相當廣泛，除了可能應用於各種材質的工件，甚至可能應用於由二種以上材質所製成的複合工件。若該至少一排屑槽122無法隨著鑽攻過程而提供足夠的排屑量，即便可因應單一材質所製成的工件，但在使用於複合工件的場合時，則有可能在鑽攻至第二種硬度較高之材質時，因累積之殘屑已堵塞於該至少一排屑槽122中進而阻塞於該鑽尾13，且影響該鑽尾13的切削效果，因而使該螺絲1失去預期的鑽攻效果，不但可能需要施加越來越大的扭力來達成鑽攻目的，甚至可能因所施加的過大外力使工件產生龜裂，進而使工件在後續使用時產生安全疑慮，就鑽攻作業的過程而言也將大幅影響到作業效率。The scope of application of screw tapping components is quite wide. In addition to being applied to workpieces of various materials, it may even be applied to composite workpieces made of more than two materials. If the at least one flute 122 cannot provide sufficient chip removal during the drilling and tapping process, even if it can be used for a workpiece made of a single material, it may be used in the case of a composite workpiece when drilling and tapping. When the material with the second hardness is higher, the screw 1 is lost because the accumulated debris has blocked the at least one chip removal groove 122 and then blocked the drill tail 13, and affected the cutting effect of the drill tail 13. The expected drilling and tapping effect may not only require the application of increasing torque to achieve the drilling and tapping purpose, but may even cause cracks in the workpiece due to the excessive external force applied, which will cause safety concerns in the subsequent use of the workpiece. Drilling and tapping In terms of the operation process, it will also greatly affect the operation efficiency.

因此，本發明之目的，即在提供一種能降低鑽攻時所需施加之扭力及快速排屑、容屑，以確保鑽攻作業之順暢而提高作業效率的螺絲。Therefore, the purpose of the present invention is to provide a screw that can reduce the torque required to be applied when drilling and tap, and quickly remove and contain chips, so as to ensure smooth drilling and tapping operations and improve working efficiency.

於是，本發明螺絲，包含一螺頭、一自該螺頭沿一軸線延伸的桿身、一連接於該桿身相反於該螺頭之一端的攻鑽件、一螺旋環設於該桿身的螺牙，及至少一凸設於該桿身的肋條。其中，該至少一凹口跨越該肋條而與該桿身的該至少一凹槽相連通。Thus, the screw of the present invention comprises a screw head, a shaft extending from the screw head along an axis, a tapping member connected to the end of the shaft opposite to the screw head, and a helical ring arranged on the shaft screw teeth, and at least one rib protruding from the shaft. Wherein, the at least one notch straddles the rib and communicates with the at least one groove of the shaft.

另外，本發明螺絲，包含一螺頭、一自該螺頭沿一軸線延伸的桿身、一連接於該桿身相反於該螺頭之一端的攻鑽件、一螺旋環設於該桿身的螺牙，及一形成於該桿身的反向牙。其中，該至少一凹口跨越該反向牙而與該桿身的該至少一凹槽相連通。In addition, the screw of the present invention includes a screw head, a shaft extending from the screw head along an axis, a tapping member connected to the end of the shaft opposite to the screw head, and a helical ring arranged on the shaft thread, and a reverse thread formed on the shaft. Wherein, the at least one notch straddles the reverse tooth and communicates with the at least one groove of the shaft.

再者，本發明螺絲，包含一螺頭、一自該螺頭沿一軸線延伸的桿身、一連接於該桿身相反於該螺頭之一端的攻鑽件、一螺旋環設於該桿身的螺牙，及多個形成於該桿身且以該軸線為軸而呈環狀排列的螺旋凸紋。其中，該至少一凹口跨越該等螺旋凸紋而與該桿身的該至少一凹槽相連通。Furthermore, the screw of the present invention comprises a screw head, a shaft extending from the screw head along an axis, a tapping member connected to the end of the shaft opposite to the screw head, and a helical ring arranged on the shaft The screw thread of the shaft, and a plurality of helical ribs formed on the shaft and arranged in a ring shape with the axis as the axis. Wherein, the at least one notch communicates with the at least one groove of the shaft across the spiral ribs.

本發明之功效在於：在該螺絲鑽攻的過程中，由該螺牙配合該攻鑽件切削而產生的殘屑，能大量容置於該凹槽中。在產生的殘屑能確實被容置的情況下，則不容易殘留於該螺牙或該攻鑽件上，藉此維持該攻鑽件的功能性，有效降低鑽攻時產生的摩擦力，同時也減少所需施加的扭力。其中，本發明螺絲可為單一材質或複合材質螺絲，皆可達成上述功效。The effect of the present invention lies in that: during the process of screw drilling and tapping, a large amount of debris produced by the cutting of the thread and the tapping part can be accommodated in the groove. In the case that the generated debris can be accommodated, it is not easy to remain on the thread or the tapping part, thereby maintaining the functionality of the tapping part and effectively reducing the friction generated during drilling. It also reduces the torque required to be applied. Wherein, the screw of the present invention can be a single material or a composite material screw, both of which can achieve the above effects.

在本發明被詳細描述之前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.

參閱圖2，本發明螺絲之一第一實施例，包含一螺頭2、一自該螺頭2沿一軸線L延伸的桿身3、一連接於該桿身3相反於該螺頭2之一端的攻鑽件4，及一螺旋環設於該桿身3的螺牙5。Referring to Fig. 2, a first embodiment of the screw of the present invention includes a screw head 2, a shaft 3 extending from the screw head 2 along an axis L, a shaft connected to the shaft 3 opposite to the screw head 2 A tapping part 4 at one end and a screw thread 5 on the shaft 3 are provided with a helical ring.

該桿身3包括一以垂直該軸線L之方向往內凹設的凹槽30、一形成該凹槽30的槽段31、一介於該槽段31與該螺頭2之間的上段32，及一介於該槽段31與該攻鑽件4之間的下段33。其中，該凹槽30是以該軸線L為軸而完整環繞，且該凹槽30沿該軸線L方向延伸的長度，需依照被鑽攻物件的厚度做適當調整，以求達到最佳效果。簡而言之，被鑽攻物件越厚，原則上該凹槽30的延伸長度越長，則可達成較佳的容屑效果，但延伸長度以不超過被鑽攻物件的厚度為準。The shaft 3 includes a groove 30 recessed inwardly in a direction perpendicular to the axis L, a groove section 31 forming the groove 30 , an upper section 32 between the groove section 31 and the screw head 2 , And a lower section 33 between the groove section 31 and the drilling part 4 . Wherein, the groove 30 completely surrounds the axis L, and the length of the groove 30 extending along the axis L needs to be properly adjusted according to the thickness of the object to be drilled in order to achieve the best effect. In short, the thicker the object to be drilled, the longer the extension length of the groove 30 can achieve a better chip containment effect in principle, but the extension length should not exceed the thickness of the object to be drilled.

另外，本第一實施例的主要特點之一，為該攻鑽件4具有一以平行該軸線L之方向延伸而呈凹陷狀的凹口40，該凹槽30是與該凹口40相連通。值得特別說明的是，該凹槽30的凹陷深度可自由調整，只要凹陷深度較該桿身3之牙底徑要低即可發揮功效。然而，雖然該凹槽30的深度越深則效果越佳，但仍須考量該桿身3的扭斷強度，故凹陷的深度是參考製造材質的扭斷強度為限，亦即凹陷之深度仍須維持本發明的整體性，限度需以能承受選用材質之機械性質的要求即可。此外，該凹口40的底部可呈現弧形、直角，或者呈現任一角度的凹陷，皆可達到預期效果。In addition, one of the main features of the first embodiment is that the drilling member 4 has a concave recess 40 extending in a direction parallel to the axis L, and the recess 30 communicates with the recess 40 . It is worth noting that the depression depth of the groove 30 can be adjusted freely, as long as the depression depth is lower than the root diameter of the shaft 3 , it can function. However, although the deeper the depth of the groove 30 is, the better the effect is, but the twist-off strength of the shaft 3 must still be considered, so the depth of the depression is limited by referring to the twist-off strength of the manufacturing material, that is, the depth of the depression is still It is necessary to maintain the integrity of the present invention, and the limit needs to be able to withstand the requirements of the mechanical properties of the selected materials. In addition, the bottom of the notch 40 can be curved, right-angled, or depressed at any angle, all of which can achieve the desired effect.

參閱圖2與圖3，使用本第一實施例鑽攻由一木板91及一金屬板92相互疊合所構成的一工件9，當該攻鑽件4已攻透該木板91而開始鑽攻該金屬板92時，因該攻鑽件4的凹口40與該凹槽30連通，鑽攻該木板91所產生的殘屑會大量容置於該凹槽30中，避免該凹口40及該螺牙5因累積殘屑而失去刃口，有利於進一步鑽攻材質更堅硬之該金屬板92。值得特別說明的是，在該桿身3之該下段33利用該攻鑽件4及該螺牙5鑽攻時，會使鑽攻的該工件9形成一鑽孔900，由於該鑽孔900的徑向寬度會較形成該凹槽30之該槽段31的徑向寬度要寬，因此形成於該槽段31的凹槽30勢必得以發揮容置殘屑的功能，並且因形成於該槽段31之凹槽30的徑寬較該鑽孔900要窄而不會直接接觸壁面，能大幅減少繼續螺攻時的摩擦力，有效降低鑽攻時的阻力及所需施加的扭力，優化該第一實施例的鑽攻性能。Referring to Fig. 2 and Fig. 3, use this first embodiment to drill and attack a workpiece 9 formed by a wooden board 91 and a metal plate 92 superimposed on each other, when the drilling part 4 has penetrated the wooden board 91 and starts drilling During this metal plate 92, because the notch 40 of this tapping part 4 is communicated with this groove 30, the residue that this plank 91 produces can be accommodated in this groove 30 in a large number, avoids this notch 40 and this groove 30. The thread 5 loses its cutting edge due to accumulated debris, which is beneficial to further drilling and tapping the metal plate 92 with a harder material. It is worth noting that when the lower section 33 of the shaft 3 is drilled with the tapping part 4 and the thread 5, a drilled hole 900 will be formed on the workpiece 9, because the drilled hole 900 The radial width will be wider than the radial width of the groove section 31 forming the groove 30, so the groove 30 formed in the groove section 31 must be able to play the function of accommodating debris, and because it is formed in the groove section The diameter width of the groove 30 of 31 is narrower than that of the drill hole 900 and does not directly contact the wall surface, which can greatly reduce the friction force when continuing screw tapping, effectively reduce the resistance and the required torque during drilling and tapping, and optimize the first part. Drilling performance of an embodiment.

參閱圖4，為本第一實施例的其中一種實施態樣，差別在於該攻鑽件4的該凹口40相較於該軸線L呈傾斜，當此種實施態樣鎖入被鑽攻物件時，具傾斜角的該凹口40相對於如圖2、3所示之平行該軸線L的該凹口40而言，更能有效率地將殘屑向外排出，或者往該凹槽30傳送。Referring to Fig. 4, it is one of the implementation styles of the first embodiment, the difference is that the notch 40 of the drilling member 4 is inclined compared with the axis L, when this implementation style is locked into the object to be drilled When compared with the notch 40 parallel to the axis L shown in Figures 2 and 3, the notch 40 with an inclination angle can more efficiently discharge debris outward, or to the groove 30 send.

參閱圖4-1至圖4-12，為本第一實施例的另外多種實施態樣，該攻鑽件4除了如圖4所呈現之常用的單面單一凹口40之外，也能採用例如圖4-1至圖4-7所示的雙面各單一凹口40且該凹口40與該凹槽30相連通、單面數道凹口40且該等凹口40均有連通該凹槽30、單面數道凹口40且僅有一凹口40連通該凹槽30、雙面數道凹口40至少有一凹口40連通該凹槽30，及螺旋凹口40。另外，值得特別說明的是，上述具多道凹口40者可僅一凹口40與該凹槽30相連通，亦可同時多道凹口40與該凹槽30相連通，在此僅呈現部分實施例，而不以圖4、圖4-1至圖4-8所示為限，舉凡類似應用皆屬本案之專利範圍。而鑽攻尾的型態，可採用如圖4、圖4-1至圖4-6所呈現之尖尾狀，或者如圖4-7所呈現之螺旋狀等等其它型態的鑽攻尾，以因應不同的鑽攻需求。再者，該桿身3還可以如圖4-8、圖4-10，及圖4-11所示，包括二個在該螺牙5與該凹槽30之間分別以遠離該軸線L之相反方向凸伸的翅片39，或是如圖4-9所示包括二個在該凹槽30與該攻鑽件4之間分別以遠離該軸線L之相反方向凸伸的翅片39，或是如圖4-12所示包括二個在該桿身3之上段32的螺牙5間(下段33的螺牙5間亦可)分別以遠離該軸線L之相反方向凸伸的翅片39，藉以增加鑽攻中段時之擴孔切削能力，且不以上述型態為限；其中，請參閱圖4-8所示，該二翅片39之外徑d’是小於該螺牙5之外徑D為較佳的使用方式。Referring to Fig. 4-1 to Fig. 4-12, it is another variety of implementation styles of the first embodiment. In addition to the commonly used single-sided single notch 40 shown in Fig. 4, the tapping part 4 can also adopt For example, each single notch 40 on both sides shown in Fig. 4-1 to Fig. 4-7 and the notch 40 communicates with the groove 30, and several notches 40 on one side and these notches 40 all communicate with the notch 40. The groove 30 , the single-side multiple grooves 40 and only one groove 40 is connected to the groove 30 , the double-sided multiple groove 40 has at least one groove 40 connected to the groove 30 , and the spiral groove 40 . In addition, it is worth noting that the above-mentioned multi-channel notches 40 may only have one notch 40 communicated with the groove 30, or multiple notches 40 may communicate with the groove 30 at the same time. Some embodiments are not limited to those shown in Fig. 4, Fig. 4-1 to Fig. 4-8, and all similar applications belong to the patent scope of this case. As for the type of drill and tap tail, you can use the pointed tail shape shown in Figure 4, Figure 4-1 to Figure 4-6, or the spiral shape shown in Figure 4-7, etc. Other types of drill and tap tail , in response to different drilling needs. Moreover, the shaft 3 can also include two holes between the thread 5 and the groove 30 that are respectively away from the axis L as shown in Fig. 4-8, Fig. 4-10, and Fig. 4-11. The fins 39 protruding in opposite directions, or as shown in FIGS. Or as shown in Figure 4-12, it includes two fins protruding in opposite directions away from the axis L between the screw teeth 5 of the upper section 32 of the shaft 3 (or between the screw teeth 5 of the lower section 33). 39, so as to increase the reaming and cutting ability when drilling and tapping the middle section, and is not limited to the above-mentioned types; wherein, please refer to Figure 4-8, the outer diameter d' of the two fins 39 is smaller than the thread 5 The outer diameter D is the preferred way of use.

參閱圖5，為本第一實施例的另一種實施態樣，針對適用於容屑的該凹槽30，實質上只要在該桿身3形成凹陷狀，即可發揮容置殘屑的效果。考量到可因應之製程的多元性，以及大量製造時的效率需求，該凹槽30除了如圖2呈現之以例如車、銑、削、輾、搓之加工手法形成與該桿身3有明顯段差之型態以外，亦可採用以例如鍛打、輾造、搓造、旋扭、沖壓、車修的技術手法而形成相對平滑連續凹面的方式來形成該凹槽30，同樣可發揮預期之容屑功效。Referring to FIG. 5 , it is another implementation of the first embodiment. As for the groove 30 suitable for chip containment, substantially as long as the shaft 3 is formed in a concave shape, the effect of containing chip can be exerted. Considering the diversity of the process that can be responded to, and the efficiency requirements of mass production, the groove 30 is not only formed by the processing methods such as turning, milling, cutting, rolling, and rubbing as shown in Figure 2, but also has obvious differences with the shaft 3. In addition to the type of step difference, the groove 30 can also be formed by using techniques such as forging, rolling, rubbing, twisting, stamping, and car repair to form a relatively smooth and continuous concave surface, which can also play the expected role. Dandruff effect.

參閱圖6與圖7，為本第一實施例的另外兩種實施態樣，針對用以容屑的該凹槽30，該攻鑽件4的樣貌形式不受限制，製作過程中可採用鍛打、輾造、搓造、旋扭、沖壓、車修、切削等等技術手法使該凹口40直接與該凹槽30相連通，不但可節省工序也可藉此降低成本。就實質功效而論，也確實可達成本第一實施例之容屑、排屑、降低扭力的功效。Referring to Fig. 6 and Fig. 7, it is another two implementation styles of the first embodiment. For the groove 30 for chip holding, the appearance of the tapping part 4 is not limited, and can be used in the manufacturing process. The notch 40 is directly connected with the groove 30 through forging, rolling, rubbing, twisting, stamping, turning, cutting, etc., which not only saves the process but also reduces the cost. In terms of substantial effects, it can indeed achieve the effects of chip containment, chip removal, and torque reduction of the first embodiment.

參閱圖8與圖9，為本發明螺絲的一第二實施例，本第二實施例與該第一實施例的差別在於：該桿身3包括二個凹槽30，該等凹槽30是以該軸線L為軸而等角設置。要特別說明的是，本第二實施例也可以是形成三個以上所述凹槽30的型態，形成有更多所述凹槽30時，該等凹槽30也是以該軸線L為軸而呈環狀間隔分布。相較於該第一實施例而言，本第二實施例也能透過該等凹槽30產生排屑、容屑、降低阻力及扭力的相同功效。除此之外，由於本第二實施例的該等凹槽30容積較該第一實施例要少，故雖然總容屑量較少，但能適度提高整體結構強度，以因應其它使用場合的需求。Referring to Fig. 8 and Fig. 9, it is a second embodiment of the screw of the present invention. The difference between this second embodiment and the first embodiment is that: the shaft 3 includes two grooves 30, and these grooves 30 are They are equiangularly arranged around the axis L as an axis. It should be noted that the second embodiment can also be formed in the form of more than three grooves 30, and when more grooves 30 are formed, the grooves 30 are also centered on the axis L. distributed in a circular interval. Compared with the first embodiment, the second embodiment can also produce the same effects of chip removal, chip containment, resistance and torque reduction through the grooves 30 . In addition, since the volume of the grooves 30 of the second embodiment is smaller than that of the first embodiment, although the total chip capacity is less, the overall structural strength can be moderately improved to meet the needs of other applications. need.

參閱圖10，為本發明螺絲的一第三實施例，與該第一實施例的差別在於：該螺牙5包括一設置於該下段33的外牙部51，也就是說，該螺牙5僅形成於該桿身3的該下段33。由於透過該凹槽30能有效在鑽攻過程中降低所需施加的扭力，且執行鑽攻時主要都是透過形成於該下段33的外牙部51來鎖入，故在所要求的拉拔力較低的情況下，只需要該外牙部51即可達成鎖附工件的力量。另外，定義該凹槽30沿平行該軸線L延伸的一段長度Z，所述長度Z是大於等於該桿身3之該上段32的牙底徑Y，以確保該凹槽30能具有一定的容積。Referring to FIG. 10 , it is a third embodiment of the screw of the present invention. The difference from the first embodiment is that the thread 5 includes an outer tooth portion 51 arranged on the lower section 33 , that is to say, the thread 5 It is only formed on the lower section 33 of the shaft 3 . Since the groove 30 can effectively reduce the required torque during drilling and tapping, and the drilling and tapping are mainly locked in through the outer tooth portion 51 formed on the lower section 33, so the required drawing In the case of low force, only the outer tooth portion 51 is needed to achieve the force for locking the workpiece. In addition, define a length Z of the groove 30 extending parallel to the axis L, the length Z is greater than or equal to the root diameter Y of the upper section 32 of the shaft 3, so as to ensure that the groove 30 can have a certain volume .

參閱圖11與圖12，為本發明螺絲的一第四實施例，與該第三實施例的差別在於：該螺牙5還包括一設置於該槽段31的內牙部52。其中，該內牙部52的外徑d是小於或等於該外牙部51的外徑D。在鑽攻的過程中，除了能在該凹槽30累積一定程度的殘屑以外，透過該內牙部52亦可增加抓附被鎖工件的力量，藉此提高拉拔力。要另外強調的是，雖然如圖11所繪示之該內牙部52是均勻形成於該凹槽30中，但在實際實施時，亦可依照實際需求調整該內牙部52分布在該凹槽30中的位置，例如亦可如圖12所呈現僅延伸至該凹槽30中的一半長度，並不以圖11所繪示之型態為限。Referring to FIG. 11 and FIG. 12 , it is a fourth embodiment of the screw of the present invention. The difference from the third embodiment is that the screw thread 5 also includes an inner thread portion 52 disposed in the groove section 31 . Wherein, the outer diameter d of the inner tooth portion 52 is smaller than or equal to the outer diameter D of the outer tooth portion 51 . In the process of drilling and tapping, in addition to accumulating a certain amount of debris in the groove 30 , the force of grasping the workpiece to be locked can also be increased through the inner teeth portion 52 , thereby increasing the pulling force. It should also be emphasized that although the internal tooth portion 52 is uniformly formed in the groove 30 as shown in FIG. The position in the groove 30 , for example, may also extend to half the length of the groove 30 as shown in FIG. 12 , and is not limited to the type shown in FIG. 11 .

參閱圖13，為本發明螺絲的一第五實施例，與該第四實施例的差別在於：該螺牙5包括一設置於該槽段31的內牙部52，及一設置於該上段32及該下段33的外牙部51。也就是說，本第五實施例相較於該第四實施例而言，在該桿身3之該上段32也形成有該外牙部51，能在鑽攻的深度較深時，進一步提升拉拔力，也能優化鎖緊能力。Referring to FIG. 13 , it is a fifth embodiment of the screw of the present invention. The difference from the fourth embodiment is that the screw thread 5 includes an inner tooth portion 52 disposed on the groove segment 31 , and an inner tooth portion 52 disposed on the upper segment 32 . And the outer teeth portion 51 of the lower section 33 . That is to say, compared with the fourth embodiment, the fifth embodiment has the outer tooth portion 51 formed on the upper section 32 of the shaft 3, which can further improve the drilling depth when the drilling depth is relatively deep. Pull-out force, also to optimize locking capacity.

參閱圖14，為本發明螺絲的一第六實施例，與該第一實施例的差別在於：本第六實施例還包含至少一凸設於該桿身3之該下段33的肋條62。所述肋條62在本第六實施例執行鑽攻作業時，能在該螺牙5鎖入的同時產生擴孔效果，藉此降低該桿身3後續螺入鑽出之鑽孔的阻力，也減少後續需切削的範圍，故能有效達成省力及減屑的功效。特別值得說明的特色是，當該肋條62設置於該槽段31與該下段33之間時，本第六實施例鎖入時造成的擴孔，能使工件與該上段32的牙底處產生間隙，形成新的容屑空間，以配合鑽攻而產生額外的容屑效果。此外，另要特別說明的是，所述肋條62除了較佳是形成於該下段33以外，即便形成於該桿身3的其它位置，也足以發揮擴孔效果，並不以圖14所繪示為限。要強調的是，當該肋條62設置於該凹槽30與該下段33之間，並使該凹口40的長度跨越該肋條62而與該凹槽30連通，為本第六實施例較佳的運用方式。Referring to FIG. 14 , it is a sixth embodiment of the screw of the present invention. The difference from the first embodiment is that the sixth embodiment further includes at least one rib 62 protruding from the lower section 33 of the shaft 3 . The ribs 62 can produce a hole reaming effect when the thread 5 is locked in when the sixth embodiment performs the drilling and tapping operation, thereby reducing the resistance of the shaft 3 to the subsequent screwing into the drilled hole, and also Reduce the scope of subsequent cutting, so it can effectively achieve the effect of labor saving and chip reduction. The feature worth noting is that when the rib 62 is arranged between the groove section 31 and the lower section 33, the reaming caused by locking in the sixth embodiment can make the workpiece and the tooth bottom of the upper section 32 produce a Clearance, forming a new chip space, in order to cooperate with drilling and tapping to produce additional chip effect. In addition, it should be particularly noted that, apart from the ribs 62 being preferably formed on the lower section 33, even if they are formed on other positions of the shaft 3, it is sufficient to have a hole-expanding effect, which is not shown in FIG. limit. It should be emphasized that when the rib 62 is arranged between the groove 30 and the lower section 33, and the length of the notch 40 crosses the rib 62 and communicates with the groove 30, it is preferred for the sixth embodiment way of using.

參閱圖15，為本發明螺絲的一第七實施例，與該第一實施例的差別在於：本第七實施例還包含一形成於該桿身3之該下段33且螺旋延伸方向與該螺牙5相反的反向牙63。本第七實施例的該反向牙63，並不會配合該螺牙5產生同向的鎖入效果，故能與如圖14所示之該第六實施例產生相同的擴徑效果，藉此達成與該第六實施例相同的省力、減屑功效。其中，若是該凹口40延伸跨越該等反向牙63，並與該凹槽30相通，則可達成本第七實施例較佳的使用。要特別說明的是，所述反向牙63除了較佳是形成於該下段33以外，即便形成於該桿身3的其它位置，也足以發揮擴孔效果，且反向牙63的數目可為數個，並不以圖15所繪示為限。Referring to Fig. 15, it is a seventh embodiment of the screw of the present invention. The difference with the first embodiment is that the seventh embodiment also includes a helical extension direction and the screw shaft 3 formed on the lower section 33. Tooth 5 is opposite to counter tooth 63 . The reverse tooth 63 of the seventh embodiment does not cooperate with the thread 5 to produce the locking effect in the same direction, so it can produce the same diameter-expanding effect as the sixth embodiment shown in Figure 14. This achieves the same labor-saving and chip-reducing effects as the sixth embodiment. Wherein, if the notch 40 extends across the opposing teeth 63 and communicates with the groove 30, then the seventh embodiment can be used better. It should be noted that, except that the reverse teeth 63 are preferably formed on the lower section 33, even if they are formed on other positions of the shaft 3, it is sufficient to achieve the effect of hole expansion, and the number of reverse teeth 63 can be several are not limited to those shown in Figure 15.

參閱圖16，為本發明螺絲的一第八實施例，與該第一實施例的差別在於：本第八實施例還包含多個形成於該桿身3之該下段33且以該軸線L為軸而呈環狀排列的螺旋凸紋64。同理，該等螺旋凸紋64也能在本第八實施例鑽攻時產生擴孔效果，藉此與該第六實施例及該第七實施例達成相同的功效。其中，若是該凹口40延伸跨越該等螺旋凸紋64並與該凹槽30相通，則可達成本第八實施例較佳的使用。同樣的，所述螺旋凸紋64除了較佳是形成於該下段33以外，即便形成於該桿身3的其它位置，也足以發揮擴孔效果，並不以圖16所繪示為限。Referring to FIG. 16 , it is an eighth embodiment of the screw of the present invention. The difference from the first embodiment is that the eighth embodiment also includes a plurality of lower sections 33 formed on the shaft 3 and centered on the axis L. The spiral ribs 64 arranged circularly. In the same way, the helical reliefs 64 can also produce a hole-enlarging effect during drilling in the eighth embodiment, thereby achieving the same effect as the sixth embodiment and the seventh embodiment. Wherein, if the notch 40 extends across the spiral ribs 64 and communicates with the groove 30 , then the eighth embodiment can be used better. Similarly, except that the spiral ribs 64 are preferably formed on the lower section 33 , even if they are formed on other positions of the shaft 3 , they are sufficient to achieve the effect of hole enlargement, and are not limited to those shown in FIG. 16 .

參閱圖17，為本發明螺絲的一第九實施例，本發明螺絲之所以能在鑽攻時發揮減少所需施加之扭力的功效，主要來自於該凹槽30額外產生的容屑效果，故只要在該桿身3上形成有該凹槽30，即可達成本發明之主要訴求。本第九實施例與該第一實施例的差別在於：該凹槽30與該螺頭2沿該軸線L的距離，小於該凹槽30與該攻鑽件4沿該軸線L的距離。也就是說，該凹槽30是形成於相對該攻鑽件4要更靠近該螺頭2的位置，仍得以達成本發明螺絲主要訴求之優化容屑、排屑功能，藉此降低鑽攻時之扭力，讓鑽攻的過程能更加順暢。因此，配合不同的鑽攻需求，也可以適度調整該凹槽30的位置，並不影響本發明所欲達成的基本功效。Referring to Fig. 17, it is a ninth embodiment of the screw of the present invention. The reason why the screw of the present invention can reduce the required torsion force during drilling and tapping is mainly due to the additional chip holding effect generated by the groove 30, so As long as the groove 30 is formed on the shaft 3, the main requirement of the present invention can be achieved. The difference between the ninth embodiment and the first embodiment is that the distance between the groove 30 and the screw head 2 along the axis L is smaller than the distance between the groove 30 and the drilling part 4 along the axis L. That is to say, the groove 30 is formed at a position closer to the screw head 2 relative to the tapping member 4, and can still achieve the optimized chip holding and chip removal functions of the screw of the present invention, thereby reducing the drilling time. The torque makes the drilling and tapping process smoother. Therefore, the position of the groove 30 can also be appropriately adjusted in accordance with different drilling and tapping requirements, without affecting the basic functions to be achieved by the present invention.

參閱圖18，為本發明螺絲之一第十實施例，本第十實施例與該第一實施例的差別在於：該桿身3的該凹槽30是自該螺頭2延伸至該攻鑽件4。透過完整延伸於該桿身3的該凹槽30，能大幅增加容屑空間，藉此因應深度較深的鑽攻。Referring to FIG. 18 , it is a tenth embodiment of the screw of the present invention. The difference between the tenth embodiment and the first embodiment is that the groove 30 of the shaft 3 extends from the screw head 2 to the tapping piece 4. Through the groove 30 extending completely on the shaft 3 , the chip space can be greatly increased, thereby responding to deeper drilling.

參閱圖19，為本發明螺絲之一第十一實施例，本第十一實施例與該第一實施例的差別在於：該桿身3的該凹槽30是自該螺頭2延伸至該攻鑽件4，且該螺牙5還包括一設置於該槽段31的內牙部52。透過完整延伸於該桿身3的該凹槽30，能大幅增加容屑空間，且透過該內牙部52亦可增加抓附被鎖工件的力量，藉此提高拉拔力，同樣能因應深度較深的鑽攻。Referring to FIG. 19 , it is an eleventh embodiment of the screw of the present invention. The difference between this eleventh embodiment and the first embodiment is that the groove 30 of the shaft 3 extends from the screw head 2 to the The tapping member 4 , and the thread 5 further includes an inner thread portion 52 disposed on the groove section 31 . Through the groove 30 extending completely on the shaft 3, the chip space can be greatly increased, and the force of grasping the workpiece to be locked can also be increased through the inner tooth part 52, so as to improve the pulling force, and can also respond to the depth Deep drilling.

參閱圖20，為本發明螺絲之一第十一實施例的另一種實施態樣，差別在於：該桿身3的該下段33並未形成外牙部51，除了能達到與圖19所示之螺絲相同之效果以外，亦能提供另外一種實施態樣。Referring to Fig. 20, it is another embodiment of an eleventh embodiment of the screw of the present invention. The difference is that the lower section 33 of the shaft 3 does not form an outer tooth portion 51, except that it can achieve the same as that shown in Fig. 19. In addition to the same effect of screws, another implementation can also be provided.

參閱圖21，為本發明螺絲之一第十二實施例，本第十二實施例與該第一實施例的差別在於：該桿身3包括多個沿該軸線L方向間隔分布的凹槽30，及多個連通該等凹槽30之連通口34，相較於該第一實施例而言，本第十二實施例也能透過該等增加的凹槽30及該等連通口34而增加排屑及容屑量，進而更有效達到降低阻力及扭力的相同功效，而該凹槽30之數量可依照應用需求或依使用者指定，而不以圖21所示為限。Referring to FIG. 21 , it is a twelfth embodiment of the screw of the present invention. The difference between this twelfth embodiment and the first embodiment is that the shaft 3 includes a plurality of grooves 30 distributed along the axis L at intervals. , and a plurality of communication openings 34 communicating with the grooves 30, compared with the first embodiment, the twelfth embodiment can also be increased through the increased grooves 30 and the communication openings 34 The amount of chip removal and chip volume can more effectively achieve the same effect of reducing resistance and torsion, and the number of the grooves 30 can be based on application requirements or specified by the user, and is not limited to that shown in FIG. 21 .

參閱圖22，為本發明螺絲之一第十三實施例，本第十三實施例與該第十二實施例的差別在於：該等凹槽30是沿該軸線L方向間隔分布且彼此不相連通，相較於該第一實施例而言，本第十三實施例同樣也能透過該等增加的凹槽30配合該凹口40產生排屑、容屑、降低阻力及扭力的相同功效。Referring to FIG. 22 , it is a thirteenth embodiment of the screw of the present invention. The difference between the thirteenth embodiment and the twelfth embodiment is that the grooves 30 are spaced along the axis L and are not connected to each other. Generally speaking, compared with the first embodiment, the thirteenth embodiment can also achieve the same effects of chip removal, chip containment, resistance reduction and torque through the increased grooves 30 and the notches 40 .

綜上所述，本發明螺絲在鑽攻的過程中，由於該至少一個凹口40與該凹槽30相互連通的設計，由該攻鑽件4配合該攻鑽件4上之凹口40切削而產生的殘屑，能大量容置於該凹槽30中，在產生的殘屑能確實被容置的情況下，則不容易殘留於該攻鑽件4及該凹口40，無論採用何種型態的該攻鑽件4，皆可維持該攻鑽件4或該凹口40得以有繼續切割的刃口，同時也有效降低鑽攻時產生的摩擦力，藉此也減少所需施加的扭力，故確實能達成本發明之目的。In summary, during the drilling and tapping process of the screw of the present invention, due to the design that the at least one notch 40 and the groove 30 communicate with each other, the tapping part 4 cooperates with the notch 40 on the tapping part 4 to cut. And the residue that produces can be accommodated in this groove 30 in a large amount, under the situation that the residue that produces can be accommodated really, then is not easy to remain in this tapping part 4 and this notch 40, no matter adopts any The tapping part 4 of each type can maintain the cutting edge of the tapping part 4 or the notch 40, and also effectively reduce the friction force generated during drilling, thereby reducing the required force. The torsional force, so really can reach the purpose of the present invention.
