Description

扣件取出裝置 Fastener extraction device

本發明是關於各種設計來取出或者移除扣件，例如螺栓及螺帽，的工具。本發明尤其是關於一種扣件取出裝置的組合，其中扣件取出裝置可以在與破損扣件之間沒有滑動的情形下取出破損的扣件。 The present invention relates to various tools designed to extract or remove fasteners, such as bolts and nuts. In particular, the present invention relates to a combination of a fastener extraction device, wherein the fastener extraction device can extract a damaged fastener without slipping between the damaged fastener and the fastener extraction device.

六角螺栓、螺帽、螺絲、及其他類似螺紋裝置，藉由結合於互補的螺紋，例如陽螺紋或陰螺紋，用來將複數工件固定結合在一起。該些型態的扣件的構造通常具有：一根圓柱形的軸桿、一個在軸桿表面的外螺紋、及在軸桿一端的頭部。外螺紋與一個攻牙於孔洞或螺帽的互補陰螺紋結合，以固定扣件，而將工件結合在一起。扣件的頭部接受一個外部的扭力。扣件的頭部是用來旋轉或驅動扣件進入陰螺紋的手段。扣件的頭部被做成特殊的形狀，讓外部工具，例如扳手，施加扭力於扣件，讓扣件以某種程度結合於陰螺紋。這些扣件簡單、便宜、有效，所以普遍地用於現代工業。使用該些扣件最常見的問題之一是：無論是陽螺紋扣件或陰螺紋扣件，這些外部工具，例如扳手，會在其頭部滑動。此一問題的產生往往是由於：磨損的扣件或工具、鏽蝕、過度扭緊、或扣件頭部的破損。有各種習知的方法可以用來移除扣件，其中有一些較具有侵犯性。一旦扣件的頭部受損，必須用較具侵犯性的方法來移除夾鎖住的扣件。在此情況下，用電鑽挖除扣件是某些使用者常常用來移除扣件的方法。雖然這一種方法在某些場合確實有效，但是卻有損害螺孔內部螺紋的高度風險。 Hexagonal bolts, nuts, screws, and other similar threaded devices are used to securely join multiple workpieces together by combining complementary threads, such as male or female threads. The structure of these types of fasteners usually has: a cylindrical shaft, an external thread on the surface of the shaft, and a head on one end of the shaft. The external thread is combined with a complementary female thread tapped into a hole or nut to secure the fastener and hold the workpieces together. The head of the fastener receives an external torque. The head of the fastener is the means used to rotate or drive the fastener into the female threads. The head of the fastener is made into a special shape to allow an external tool, such as a wrench, to apply torque to the fastener, allowing the fastener to be combined with the female thread to some extent. These fasteners are simple, cheap, and effective, so they are commonly used in modern industry. One of the most common problems with these fasteners, whether they are male or female, is that these external tools, such as wrenches, can slip on their heads. This problem often occurs due to: worn fasteners or tools, corrosion, over-tightening, or damage to the fastener head. There are various conventional methods for removing fasteners, some of which are more invasive. Once the head of a fastener is damaged, more invasive methods must be used to remove the clip-locked fastener. In this case, digging out the fastener with an electric drill is a method that some users often use to remove the fastener. Although this method does work in some situations, it carries a high risk of damaging the internal threads of the screw hole.

使用該些扣件最常見的問題之一是：無論是陽螺紋扣件或陰螺紋扣件，這些外部工具，例如扳手，會在其頭部滑動。此一問題的產生往往是由於：磨損的扣件或工具、鏽蝕、過度扭緊、或扣件頭部的破損。有各種習知的方法可以用來移除扣件，其中有一些較具有侵犯性。一旦扣件的頭部受損，必須用較具侵犯性的方法來移除夾鎖住的扣件。在此情況下，用電鑽挖除扣件是某些使用者常常用來移除扣件的方法。雖然這一種方法在某些場合確實有效，但是卻有損害螺孔內部螺紋的高度風險。 One of the most common problems with these fasteners, whether they are male or female, is that these external tools, such as wrenches, can slip on their heads. This problem often occurs due to: worn fasteners or tools, rust, over-tightening, or damage to the fastener head. There are various conventional methods for removing fasteners, some of which are more invasive. Once the head of a fastener is damaged, more invasive methods must be used to remove the clip-locked fastener. In this case, digging out the fastener with an electric drill is a method that some users often use to remove the fastener. Although this method does work in some situations, it carries a high risk of damaging the internal threads of the screw hole.

本發明提供一種扣件取出裝置，其能夠確實地消除扣件及取出裝置之間發生滑移的可能性。本發明使用一系列結合在一起的鍵槽結構來咬住扣件的頭部，並且有效地在取出裝置及扣件的頭部之間傳遞扭力。本發明也解決了傳統的螺栓取出工具常見的問題，例如：扣件頭部或扣件本身附著於扣件取出工具的問題。更者，本發明讓使用者可以輕易地將殘餘的材料或者移除的扣件從取出裝置中退出。 The present invention provides a fastener extraction device that can reliably eliminate the possibility of slippage between the fastener and the extraction device.

首先要特別說明的是：本說明書所使用的圖示僅是用於說明本發明的某些實施例，本發明的範圍並不受該些圖示的限制。 First of all, it should be noted that the diagrams used in this specification are only used to illustrate certain embodiments of the present invention, and the scope of the present invention is not limited by these diagrams.

本發明是關於一種扣件取出工具及扣件取出工具配件的技術。本發明揭露多種扣件取出起子頭，其包含陽螺紋及陰螺紋的實施例。從扣件取出工具移除破損的扣件是一件困難的工作。本發明藉由揭露一種退出套筒來解決此一問題，其中退出套筒退與出裝置結合，是特別設計來幫助使用者移除任何已經鉗卡於扣件取出工具的破損扣件。 The present invention relates to a fastener removal tool and a fastener removal tool accessory technology. The present invention discloses a variety of fastener extraction screwdriver bits, which include embodiments of male threads and female threads. Removing a broken fastener is a difficult job with the Fastener Removal Tool. The present invention solves this problem by disclosing an extraction sleeve, in which the extraction sleeve is combined with an extraction device and is specially designed to help the user remove any damaged fasteners that have been clamped on the fastener removal tool.

請參照圖1及圖2。本發明包含：一個桿體1、一個驅動頭2、一個扭力工具本體3、一個外螺紋15、一個管狀套筒16、一個內螺紋17、及一個螺帽18。桿體1及驅動頭2讓本發明獲得以附裝於一個外部扭力工具，並且經由扭力工具本體3施加扭力於具有承窩的扣件取出這個扣件，就如同習知的設計一般。外部扭力工具可以是但不限於是：電鑽、扭力扳手、氣動鑽、套筒螺絲起子、及其他類似的扭力工具。驅動頭2是做為與外部扭力工具結合的元件。更詳言之，驅動頭2的形狀類似螺帽，並且同心地連接於桿體1的一端。驅動頭2的形狀一六角形為佳，雖然其它的幾何形狀也可以使用。在本發明的一個實施例，驅動頭2的形狀是一個正方形。在本發明的另外一個實施例，驅動頭2的的底端是一個圓拱形，其中驅動頭2的的底端是是隔著驅動頭2相對於桿體1的一端。這個圓拱形的設計形成一個突出的表面，而衝擊的力道將會施加於這一個突出的表面，以強迫扭力工具本體3進入要被取出的物件中。然而，本發明並未特別限制這一個衝擊的表面是一個圓拱形。 Please refer to Figure 1 and Figure 2. The invention includes: a rod body 1, a driving head 2, a torque tool body 3, an external thread 15, a tubular sleeve 16, an internal thread 17, and a nut 18. The rod body 1 and the driving head 2 allow the present invention to be attached to an external torque tool, and torque is applied to the fastener with the socket via the torque tool body 3 to remove the fastener, just like the conventional design. External torque tools may be, but are not limited to, electric drills, torque wrenches, pneumatic drills, socket screwdrivers, and other similar torque tools. The driving head 2 is used as a component combined with an external torque tool. In more detail, the driving head 2 is shaped like a nut and is concentrically connected to one end of the rod body 1 . The shape of the drive head 2 is preferably hexagonal, although other geometries may be used. In one embodiment of the invention, the shape of the driving head 2 is a square. In another embodiment of the present invention, the bottom end of the driving head 2 is in a round arch shape, and the bottom end of the driving head 2 is the end opposite to the rod body 1 across the driving head 2 . This dome-shaped design forms a protruding surface, and the impact force will be exerted on this protruding surface to force the torque tool body 3 to enter the object to be removed. However, the present invention does not specifically limit the impact surface to be a dome shape.

扭力工具本體3是一個桿狀構造，其能夠與一個被夾咬住的扣件結合，例如一個具有承窩的螺絲、一個具有承窩的螺桿、一個被鑽出特定尺寸孔洞的破損螺桿或任何具有螺紋的桿狀物體，以便施加扭力來退出被夾咬住的扣件。扭力工具本體3沿著桿體1向與驅動頭相反的方向分佈。請參照圖3。扭力工具本體3包含：複數個側壁4、至少一個結合特徵8、一個第一基部13、及一個第二基部14。一般而言，扭力工具本體3是一個由高強度金屬所製造的的稜柱狀構造，並且同心地連接於桿體1的一端。複數個側壁4之中的每一個會結合於承窩扣件之內並且咬住承窩扣件，藉此可以有效率地將扭力從外部扭力工具傳遞到承窩扣件。複數個側壁4圍繞著扭力工具本體3的一個旋轉軸12分佈，形成一個跟承窩扣件形狀互補的幾何形狀。複數個側壁4可以變化以配合各種承窩扣件的形狀。在本發明的一個實施例，側壁4的數目是6，使扭力工具本體3的截面為一個六面形。在本發明的另外一個實施例，側壁4的數目是4，使扭力工具本體3的截面為一個正方形。 The torque tool body 3 is a rod-shaped structure that can be combined with a clamped fastener, such as a screw with a socket, a screw with a socket, a broken screw with a hole of a specific size drilled, or any A rod-like object that is threaded to apply torque to disengage a clamped fastener. The torque tool body 3 is distributed along the rod body 1 in the opposite direction to the driving head. Please refer to Figure 3. The torque tool body 3 includes a plurality of side walls 4 , at least one coupling feature 8 , a first base 13 , and a second base 14 . Generally speaking, the torque tool body 3 is a prismatic structure made of high-strength metal, and is concentrically connected to one end of the rod body 1 . Each of the plurality of side walls 4 will be integrated into the socket fastener and bite the socket fastener, thereby efficiently transmitting torque from the external torque tool to the socket fastener. A plurality of side walls 4 are distributed around a rotation axis 12 of the torque tool body 3 to form a A geometric shape that is complementary to the shape of the socket fastener. The plurality of side walls 4 can be varied to match various socket fastener shapes. In one embodiment of the invention, the number of side walls 4 is six, making the cross section of the torque tool body 3 a hexahedral shape. In another embodiment of the invention, the number of side walls 4 is four, so that the cross section of the torque tool body 3 is a square.

第一基部13及第二基部14隔著側壁4彼此相對，桿體1則是連接於第二基部14並且與第一基部13相對。更者，第一基部13及第二基部14垂直於複數個側壁4之中的每一個，藉此形成扭力工具本體3的稜柱狀構造。在本發明的一個較佳實施例，第一基部13更包含一個第一基部表面，而且第一基部表面垂直於複數個側壁4之中的每一個。在本發明的一個較佳實施例，複數個側壁4之中的每一個及第一基部13之間具有一個側向邊緣21，而這個側向邊緣21有進行去角處理。再者，第一基部13可以被做成一個錐形而具有一個尖頭，就像一個衝頭工具。當衝擊的力量施加於驅動頭2，結合特徵8會咬入要被移除物體的側面。藉此，結合特徵8會增加複數個側壁4及承窩扣件之間的摩擦力及彼此之間連結，因此可以防止彼此之間相對的滑動。一個結合特徵8會結合於複數個側壁4之中的一個特定側壁20，而這個特定側壁20是代表複數個側壁4之中的任一個。 The first base 13 and the second base 14 face each other across the side wall 4 , and the rod 1 is connected to the second base 14 and faces the first base 13 . Furthermore, the first base 13 and the second base 14 are perpendicular to each of the plurality of side walls 4 , thereby forming a prismatic structure of the torque tool body 3 . In a preferred embodiment of the present invention, the first base 13 further includes a first base surface, and the first base surface is perpendicular to each of the plurality of side walls 4 . In a preferred embodiment of the present invention, there is a lateral edge 21 between each of the plurality of side walls 4 and the first base 13, and the lateral edge 21 is chamfered. Furthermore, the first base 13 can be made tapered with a pointed tip, like a punch tool. When the force of the impact is applied to the drive head 2, the engagement features 8 bite into the sides of the object to be removed. Thereby, the coupling features 8 will increase the friction and connection between the plurality of side walls 4 and the socket fasteners, thereby preventing relative sliding between each other. A bonding feature 8 will be bonded to a specific sidewall 20 among the plurality of sidewalls 4 , and the specific sidewall 20 represents any one of the plurality of sidewalls 4 .

管狀套筒16是一個長管狀的構造並且他的內徑與桿體1的外徑互相配合。內螺紋17、外螺紋15、管狀套筒16、及螺帽18共同形成一個退出機構，用以將殘餘的材料或承窩扣件從扭力工具本體3移除。在本發明的一個較佳實施例，管狀套筒16在其第一端的方向的直徑沿著管狀套筒16逐步增加，其中管狀套筒16的第一端靠近扭力工具本體3。如此可以增加管狀套筒16及附著於扭力工具本體3的外物的接觸面積。管狀套筒16沿著桿體1移動並推頂著在扭力工具本體3上面的承窩扣件，一直到承窩扣件，也就是所謂的外物，被退出。外螺紋15在扭力工具本體3及驅動頭2之間沿著桿體1延伸。更者，外螺紋15連接於桿體1的側面。內螺紋17被設計成互補於外螺紋15，因此可以以互鎖的方式結合。內螺紋17在管狀套筒16之內沿著管狀套筒16延伸。更者，內螺紋17切入管狀套筒16的內側面。為了方便操作，桿體1同心地位於管狀套筒16之內，並且內螺紋17機械地結合於外螺紋15。如此，在桿體1與管狀套筒16互相結合時，管狀套筒16可以沿著桿體1滑動。在使用者用扭力工具本體3取出一個被夾咬住的承窩扣件之後，使用者可能需要將承窩扣件從扭力工具本體3中移除。在操作時，使用者對著桿體1旋轉管狀套筒16，以將管狀套筒16移向扭力工具本體3，直到管狀套筒16頂抵著承窩扣件並且將承窩扣件退出扭力工具本體3。使用者可以使用手來旋轉管狀套筒16，但是也可以使用兩個扭力工具，例如扳手，藉著槓桿作用來旋轉管狀套筒16。其中一個扳手經由驅動頭2機械地結合於桿體1，另一個扳手則是藉由螺帽18機械地結合於管狀套筒16。為達於此，螺帽18同心地連結於管狀套筒16的一端。桿體1則是位於螺帽18之內。螺帽18的形狀與六角形為佳，雖然其他的幾何形狀也可以使用。管狀套筒16及螺帽18的的尺寸、長度，及材料都可以改變，以配合實際的需要及使用者的喜好。 The tubular sleeve 16 is a long tubular structure and its inner diameter matches the outer diameter of the rod body 1 . The internal thread 17 , the external thread 15 , the tubular sleeve 16 , and the nut 18 together form an extraction mechanism for removing residual material or socket fasteners from the torque tool body 3 . In a preferred embodiment of the present invention, the diameter of the tubular sleeve 16 in the direction of its first end gradually increases along the tubular sleeve 16 , where the first end of the tubular sleeve 16 is close to the torque tool body 3 . This can increase the contact area between the tubular sleeve 16 and foreign objects attached to the torque tool body 3 . The tubular sleeve 16 moves along the rod body 1 and pushes against the socket fastener on the torsion tool body 3 until the socket fastener, the so-called foreign object, is withdrawn. External thread 15 in The space between the torque tool body 3 and the driving head 2 extends along the rod body 1 . Furthermore, the external thread 15 is connected to the side surface of the rod body 1 . The internal thread 17 is designed to be complementary to the external thread 15 and can therefore be combined in an interlocking manner. The internal thread 17 extends within the tubular sleeve 16 along the tubular sleeve 16 . Furthermore, the internal thread 17 is cut into the inner side of the tubular sleeve 16 . To facilitate operation, the rod 1 is concentrically located within the tubular sleeve 16 , and the internal thread 17 is mechanically coupled to the external thread 15 . In this way, when the rod body 1 and the tubular sleeve 16 are combined with each other, the tubular sleeve 16 can slide along the rod body 1 . After the user uses the torque tool body 3 to remove a clamped socket fastener, the user may need to remove the socket fastener from the torque tool body 3 . During operation, the user rotates the tubular sleeve 16 toward the rod body 1 to move the tubular sleeve 16 toward the torque tool body 3 until the tubular sleeve 16 abuts the socket fastener and removes the socket fastener from the torque. Tool body 3. The user can use their hands to rotate the tubular sleeve 16, but they can also use two torque tools, such as a wrench, to rotate the tubular sleeve 16 by leveraging it. One of the wrenches is mechanically coupled to the rod body 1 via the driving head 2, and the other wrench is mechanically coupled to the tubular sleeve 16 via the nut 18. To achieve this, the nut 18 is concentrically connected to one end of the tubular sleeve 16 . Rod body 1 is located within nut 18. The preferred shape of nut 18 is hexagonal, although other geometries may be used. The size, length, and material of the tubular sleeve 16 and nut 18 can be changed to meet actual needs and user preferences.

請參照圖3及圖4。在本發明的一個實施例，結合特徵8是一個結合凹穴。複數個側壁4之中的每一個更包含：一個第一側緣5、一個第二側緣6、及一個支撐面7。支撐面7物理性地頂抵著一個承窩扣件，尤其是承窩扣件頭部的側壁。第一側緣5及第二側緣6隔著支撐面7彼此相對。無論從頂視的角度或底視的角度，複數個側壁4之中每一個的第一側緣5及第二側緣6構成扭力工具本體3的角隅。結合凹穴垂直凹入特定側壁20的支撐面7，藉此在支撐面7產生一個額外的咬合點/咬合齒。這個咬合點是由結合凹穴及支撐面7共同產生。在本發明的一個實施例，這個結合凹穴在扭力工具本體3上從第一基部13延伸到第二基部14。如此，可以確保額外的咬合沿著則扭力工具本體3的長度延伸，以得到最大的咬合能力。在本發明的一個實施例，這個結合凹穴從第一基部13到第二基部14逐漸變小，如圖3所示。為了確保得到最大的咬合能力，結合凹穴的一個整體橫斷面9平行於第一基部13及第二基部14。 Please refer to Figure 3 and Figure 4. In one embodiment of the invention, the bonding feature 8 is a bonding pocket. Each of the plurality of side walls 4 further includes: a first side edge 5 , a second side edge 6 , and a supporting surface 7 . The support surface 7 physically bears against a socket fastener, in particular the side wall of the socket fastener head. The first side edge 5 and the second side edge 6 face each other across the supporting surface 7 . No matter from a top view or a bottom view, the first side edge 5 and the second side edge 6 of each of the plurality of side walls 4 form a corner of the torque tool body 3 . The binding pocket is vertically recessed into the support surface 7 of a specific side wall 20 , thereby creating an additional bite point/teeth on the support surface 7 . This bite point is produced by the combination of the recess and the supporting surface 7 . In the present invention In one embodiment, this coupling recess extends from the first base 13 to the second base 14 on the torque tool body 3 . In this way, it is ensured that additional bite extends along the length of the torque tool body 3 to obtain maximum bite capability.

Excellent biting power of traditional tools. Traditional tools are simply designed to push material away. The excellent bite capability of the present invention is particularly evident in the sockets of worn or damaged fasteners. The curved area 10 is a partially circular curve adjacent the first side edge 5 of a particular side wall 20 . The straight region 11 is adjacent to the curved region 10 and relative to the first side edge 5 of a particular side wall 20 . The straight area 11 guides a portion of the socket element against the formed joining teeth. A straight area 11 extends from the curved area 10 to this particular side wall 20 second side edge 6. In other words, the straight area 11 starts from the curved area 10 and ends at the second side edge 6 of this particular side wall 20 . By inverting the positions of the curved area 10 and the straight line area 11, this embodiment can be implemented with a clockwise configuration or a counterclockwise configuration.

Furthermore, the combination concave point is a first length away from the first side edge 5 of the specific side wall 20 and a second length away from the second side edge 6 of the specific side wall 20, wherein the first length is equal to the second length. In other embodiments of the invention, the first length is not necessarily equal to the second length. This position allows the coupling pocket to engage the inside edge of the socket fastener to achieve maximum torque transfer efficiency and minimum slippage. Moreover, this embodiment can rotate the socket fastener in a clockwise direction or a counterclockwise direction.
