Description

活動扳手頭構件adjustable wrench head

本發明涉及工具的辨識領域，特別是指一種頭構件，利用不同顏色來辨識一個尺寸規格的螺接件或工件。The invention relates to the field of tool identification, in particular to a head member, which uses different colors to identify a screw connection or a workpiece of a size specification.

諸如開口扳手、活動扳手、梅花扳手、六角扳手及其附屬零件（如套筒）等已知的工具，常用的標記方式包括：工具表面刻印至少一個識別性的文字或符號，或在工具表面壓印大面積的識別標記，提供永久標記達到識別目的。Known tools such as open-end wrenches, adjustable wrenches, Torx wrenches, hexagonal wrenches and their accessory parts (such as sockets), etc., commonly used marking methods include: at least one identifying word or symbol is engraved on the surface of the tool, or the surface of the tool is pressed. Print a large area of identification marks to provide permanent marks for identification purposes.

前述方法在工具已使用多年，仍然存在某些問題。例如正常使用情況下，油脂覆蓋局部或全部的標記，導致一名使用者停止工作，拭去油脂並閱讀標記，確定工具適用工件的尺寸規格。或者，某些開口扳手背面沒有標記，必須將扳手翻轉至正面，甚至於從橫向位置旋轉到豎立位置，才能清楚地辨認標記。The aforementioned method has been used in tools for many years, and there are still some problems. For example, under normal use, grease covers part or all of the marking, causing a user to stop working, wipe off the grease and read the marking to determine the size of the workpiece for which the tool is intended. Alternatively, some open-ended wrenches have no markings on the back and must be turned over to the front, or even rotated from a landscape to an upright position, to clearly identify the markings.

為了減少或消除前述方法存在的問題，美國第4,982,627號發明專利案提供一種工具識別方法，包括：至少一個凹槽形成於工具的表面，所述的凹槽具備預定的寬度，用來區分英制和公制的尺寸；設在凹槽內以形成色環的著色材料，所述的著色材料陷入工具的表面下方並指示尺寸數字；用各種顏色來定義十個***數字的圖表，通過使用任意數量的凹槽和顏色來顯示任何規格，形成無限的尺寸組合。In order to reduce or eliminate the problems existing in the aforementioned methods, US Patent No. 4,982,627 provides a tool identification method, comprising: at least one groove is formed on the surface of the tool, and the groove has a predetermined width for distinguishing between inch and Metric size; tinting material set in grooves to form a color ring, said tinting material sinking under the surface of the tool and indicating the dimensional numbers; a chart of ten Arabic numerals defined in various colors, by using any number of recesses Slots and colors to display any size, creating unlimited size combinations.

但是，每個顏色代表的數字需要長期記憶。若不常使用，頭腦記不得顏色代表的數字，工具對應螺接件或工件的關係容易混淆，徒然增加搜尋的時間，相對延誤組裝或維修的效率。However, the number represented by each color requires long-term memory. If it is not used frequently, the mind cannot remember the number represented by the color, and the relationship between the tool and the screw connection or the workpiece is easily confused, which will increase the search time in vain, and relatively delay the efficiency of assembly or maintenance.

其次，每個工具有至少一個操作端，適用單一尺寸規格的螺接件或工件。隨身攜帶一組不同尺寸的工具，才能選用合適的工具，操作螺接件或工件，執行鎖緊或旋鬆作業。這麼多工具的體積龐大，不利於搬運。而且，容易選到尺寸錯誤的工具。Second, each tool has at least one operating end for a single size screw or workpiece. Carry a set of tools of different sizes with you in order to select the right tool to operate a screw connection or workpiece, and perform locking or loosening operations. The bulk of so many tools is not conducive to handling. Moreover, it is easy to choose the wrong size tool.

另外，該標記沒有扭矩值的告知。該名使用者憑藉個人的經驗，決定工具的扭矩，執行鎖緊或旋鬆作業。過度的扭曲，破壞螺接件或工件結構而不堪使用，或是鎖緊程度不足，螺接件或工件容易受到震動而鬆脫。In addition, this tag has no torque value notification. The user determines the torque of the tool and performs the locking or loosening operation based on personal experience. Excessive twisting, destroying the structure of the screw connection or workpiece and making it unbearable for use, or insufficient locking, the screw connection or workpiece is easily loosened by vibration.

中國第2118617號實用新型專利案提供一種活動扳手，係在一個手柄配置一個固定顎與一個活動顎。該活動顎與手柄並排處各有一組刻度，因為十個刻度才有一個***數字，所以活動顎配合固定顎夾持螺接件或工件，按照度量衡的十進位制度配合***數字，演算二組刻度的數據，才能知道螺接件或工件的尺寸規格。甚至於，根據手柄中間部位的換算表，進行公制與英制單位的換算，非常麻煩。Chinese Utility Model Patent No. 2118617 provides an adjustable wrench, which is tied to a handle and is equipped with a fixed jaw and a movable jaw. The movable jaw and the handle have a set of scales side by side, because there are only one Arabic numeral for ten scales, so the movable jaw cooperates with the fixed jaw to clamp the screw or workpiece, and calculates two sets of scales according to the decimal system of weights and measures with Arabic numerals The data can only know the size of the screw or workpiece. Even, according to the conversion table in the middle of the handle, it is very troublesome to convert between metric and imperial units.

雖然，所述的換算表包括尺寸規格與扭矩值對應關係，卻需要心算或電子計算機的演算，不僅花費計算時間，而且刻度間隔細微的距離，易因視差取得偏差值，影響到測量結果。Although the conversion table includes the corresponding relationship between size specifications and torque values, it requires mental arithmetic or computer calculations, which not only takes time to calculate, but also has a small distance between the scales, which is easy to obtain deviation values due to parallax, which affects the measurement results.

因此，如何改善顏色辨識與刻度量測的弊端，就成為本發明亟待解決的課題。Therefore, how to improve the disadvantages of color recognition and scale measurement has become an urgent problem to be solved by the present invention.

鑒於此，本發明提供一種頭構件，既能組成一個活動扳手，又能拆卸更換。本發明主要目的在於：不必經過度量衡的演算，通過顏色識別相應尺寸規格的螺接件，有效解決先前技術關於顏色辨識與刻度量測的弊端。In view of this, the present invention provides a head member, which can not only form an adjustable wrench, but also be disassembled and replaced. The main purpose of the present invention is: without going through the calculation of weights and measures, identifying the screw joints of the corresponding size specifications by color, effectively solving the drawbacks of the prior art regarding color identification and scale measurement.

源於上述目的之達成，本發明的頭構件具備一個本體，該本體的前端立著一個固定顎，一個活動顎配置在本體的前端而可移動，改變活動顎至固定顎的距離。根據一組螺接件不同的尺寸規格，在本體表面設置顏色互異的一組辨識區，每個辨識區對應單一螺接件的尺寸規格。當活動顎配合固定顎夾持螺接件，不必經過度量衡的演算，就能以活動顎側面的一個指示部指向辨識區，通過顏色識別相應尺寸規格的螺接件。In order to achieve the above objects, the head member of the present invention includes a main body with a fixed jaw standing at the front end of the main body, and a movable jaw arranged at the front end of the main body to be movable to change the distance from the movable jaw to the fixed jaw. According to the different size specifications of a group of screw joints, a set of identification areas with different colors are arranged on the surface of the body, and each identification area corresponds to the size specifications of a single screw joint. When the movable jaw cooperates with the fixed jaw to clamp the threaded parts, without going through the calculation of weights and measures, an indication part on the side of the movable jaw can be pointed to the identification area, and the threaded parts of the corresponding size can be identified by color.

如此，本發明沒有刻度的量測，不需要心算或電子計算機轉換等過程，有效解決傳統式顏色辨識需要長期記憶、不利挑選搬運、欠缺扭矩值告知等缺點。In this way, the present invention has no scale measurement, does not require mental arithmetic or computer conversion and other processes, effectively solving the shortcomings of traditional color identification requiring long-term memory, unfavorable selection and handling, and lack of torque value notification.

為使本發明之目的、構造、特徵和優點淺顯易懂，茲舉一個或以上較佳的實施例，配合所附的圖式詳細說明如下。In order to make the objects, structures, features and advantages of the present invention easy to understand, one or more preferred embodiments are presented and described in detail as follows in conjunction with the accompanying drawings.

如第1圖所示，該頭構件10的第一實施例包括，但不限於：一個本體11、一組辨識區、一個操作件、一個活動顎40與一個指示部47。As shown in FIG. 1 , the first embodiment of the head member 10 includes, but is not limited to, a main body 11 , a set of identification areas, an operating member, a movable jaw 40 and an indication portion 47 .

其中，該本體11是堅固的，其一端形成一個基座18。在基座18較大的面積中央往外延伸一個***部19，該***部19的一個珠槽21安裝一個鋼珠20與一個彈性件22。該彈性件22推動鋼珠20局部露出***部19側邊為常態。該鋼珠20不輕易離開***部19，其受力退入珠槽21，同時壓縮彈性件22產生形變。Therein, the body 11 is solid, and a base 18 is formed at one end thereof. An insertion portion 19 extends outward from the center of the larger area of the base 18 , and a ball groove 21 of the insertion portion 19 is installed with a steel ball 20 and an elastic member 22 . The elastic member 22 pushes the steel ball 20 to partially expose the side edge of the insertion portion 19 in a normal state. The steel ball 20 does not easily leave the insertion portion 19 , and is forced to retreat into the ball groove 21 , and at the same time, the elastic member 22 is compressed and deformed.

該本體11的另端視為前端14。一個固定顎12豎立在前端14固定不動，該固定顎12的一面嚙合面13鄰接前端14。一個開口槽15形成於本體11的前端14，其包括：一道直孔151順著前端14平行方向貫穿本體11的兩邊；一個開口152銜接直孔151與本體11的前端14。The other end of the main body 11 is regarded as the front end 14 . A fixed jaw 12 is erected and fixed at the front end 14 , and an engaging surface 13 of the fixed jaw 12 is adjacent to the front end 14 . An opening slot 15 is formed on the front end 14 of the main body 11 , which includes: a straight hole 151 runs through both sides of the main body 11 along the parallel direction of the front end 14 ; an opening 152 connects the straight hole 151 and the front end 14 of the main body 11 .

圖中，該活動顎40是堅固的角塊，該角塊與一根直桿43被一個扁平部42連在一起。該直桿43外側陷入一排齒谷44，使直桿43單邊擁有多個齒45。當直桿43進入直孔151，該扁平部42通過開口152，支持活動顎40沿著前端14相對固定顎12往復運動。該直桿43的直徑（或寬度）大於開口152的距離，阻止活動顎40經由開口152脫離本體11。該活動顎40朝向固定顎12的一面視為嚙合面41。In the figure, the movable jaw 40 is a solid corner block, which is connected with a straight rod 43 by a flat portion 42 . The outer side of the straight rod 43 sinks into a row of tooth valleys 44 , so that the straight rod 43 has a plurality of teeth 45 on one side. When the straight rod 43 enters the straight hole 151 , the flat portion 42 passes through the opening 152 to support the movable jaw 40 to reciprocate relative to the fixed jaw 12 along the front end 14 . The diameter (or width) of the straight rod 43 is greater than the distance from the opening 152 , preventing the movable jaw 40 from detaching from the main body 11 through the opening 152 . The side of the movable jaw 40 facing the fixed jaw 12 is regarded as the meshing surface 41 .

另外，從本體11頂部（即第2圖的第一表面23）到底部（即第9圖的第二表面231）形成一個操作孔17。該操作孔17與直孔151相通，該直桿43局部露出操作孔17而能見到齒谷44和齒45。順著直孔151軸心的平行方向，一個軸孔16形成於本體11內部並穿過操作孔17的對邊。所述的操作件置入操作孔17，一根軸34經由軸孔16通過操作件的一個圓柱體35。該操作件的一個螺旋盤36環繞圓柱體35外部的圓周面，該螺旋盤36局部超出本體11的表面，從而嚙接（或咬合）直桿43的齒45，提供活動顎40位移所需的動力。In addition, an operation hole 17 is formed from the top of the body 11 (ie, the first surface 23 in FIG. 2 ) to the bottom (ie, the second surface 231 in FIG. 9 ). The operating hole 17 communicates with the straight hole 151 , and the straight rod 43 partially exposes the operating hole 17 to see the tooth valley 44 and the tooth 45 . Along the direction parallel to the axis of the straight hole 151 , a shaft hole 16 is formed inside the body 11 and passes through the opposite side of the operation hole 17 . The operating member is inserted into the operating hole 17 , and a shaft 34 passes through a cylindrical body 35 of the operating member through the shaft hole 16 . A helical disk 36 of the operating member surrounds the outer circumferential surface of the cylinder 35, the helical disk 36 partially protrudes beyond the surface of the body 11, thereby engaging (or engaging) the teeth 45 of the straight rod 43, providing the required displacement of the movable jaw 40. power.

在本實施例，該組辨識區包括，但不限於：一個第一辨識區24、一個第二辨識區25、一個第三辨識區26與一個第四辨識區27。該組辨識區的顏色互異，並根據一組螺接件不同的尺寸規格設在本體11的第一表面23。因此，每個辨識區的顏色對應單一螺接件的尺寸規格。In this embodiment, the set of identification areas includes, but is not limited to: a first identification area 24 , a second identification area 25 , a third identification area 26 and a fourth identification area 27 . The colors of the identification areas are different from each other, and are provided on the first surface 23 of the main body 11 according to the different sizes of a group of screw elements. Therefore, the color of each identification area corresponds to the size specification of a single screw connection.

該指示部47設在活動顎40的側面46。勿庸演算度量衡，該活動顎40配合固定顎12夾持螺接件（圖未視），以指示部47指向其中之一辨識區，通過顏色識別相應尺寸規格的螺接件。The indicating portion 47 is provided on the side surface 46 of the movable jaw 40 . It is not necessary to calculate weights and measures, the movable jaw 40 cooperates with the fixed jaw 12 to clamp the screw connection (not shown in the figure), and the indicator 47 points to one of the identification areas, and the screw connection of the corresponding size specification is identified by color.

下列的一個表格，以對邊距離（mm）表示螺接件尺寸規格，採用國際單位制（Nm）代表扭矩值，顯示該組辨識區、螺接件尺寸規格與一個扭矩值的對應關係。該組辨識區螺接件尺寸規格扭矩值第一辨識區（24） 17 18 第二辨識區（25） 22 42 第三辨識區（26） 26 55 第四辨識區（27） 29 65 In the following table, the dimension of the screw joint is represented by the distance from the opposite side (mm), and the torque value is represented by the international system of units (Nm), and the corresponding relationship between the identification area, the size of the screw joint and a torque value is displayed. The identification area of the group Dimensions of screw fittings Torque value The first identification area (24) 17 18 The second identification area (25) twenty two 42 The third identification area (26) 26 55 Fourth Recognition Area (27) 29 65

使用時，該螺旋盤36連帶圓柱體35同向轉動，透過齒45的嚙接關係，驅使直桿43帶動扁平部42一起移動，改變活動顎40與固定顎12相隔的距離，從第3圖的距離D4，歷經第4圖的距離D3與第5圖的距離D2，一路縮減至第6圖的距離D1。When in use, the spiral disc 36 rotates in the same direction with the cylindrical body 35, through the engagement relationship of the teeth 45, the straight rod 43 is driven to drive the flat part 42 to move together, and the distance between the movable jaw 40 and the fixed jaw 12 is changed. The distance D4 of , goes through the distance D3 of the 4th picture and the distance D2 of the 5th picture, all the way reduced to the distance D1 of the 6th picture.

如第3圖所示，該指示部47指向第四辨識區27，通過第四辨識區27的色料33顏色，參酌上述表格得知，該距離D4代表活動顎40配合固定顎12夾持螺接件的尺寸規格為29mm。在第4圖中，該第三辨識區26的色料33顏色，瞭解距離D3相當於尺寸規格為26mm的螺接件。第5圖中，該第二辨識區25的色料33顏色，表示距離D2相當於尺寸規格為22mm的螺接件。當然，第6圖以第一辨識區24的色料33顏色，呈現距離D1相當於尺寸規格為17mm的螺接件。As shown in FIG. 3, the indicating portion 47 points to the fourth identification area 27. According to the color of the color material 33 in the fourth identification area 27, referring to the above table, it can be known that the distance D4 represents that the movable jaw 40 cooperates with the fixed jaw 12 to clamp the screw. The size of the connector is 29mm. In FIG. 4 , the color of the colorant 33 in the third identification area 26 shows that the distance D3 is equivalent to a screw connection with a size of 26 mm. In Fig. 5, the color of the color material 33 in the second identification area 25 indicates that the distance D2 is equivalent to a screw connection with a size specification of 22 mm. Of course, Fig. 6 uses the color of the color material 33 in the first identification area 24 to present a screw connection with a distance D1 equivalent to a size of 17 mm.

尤其是，尺寸記得與否，在本發明屬於無足輕重的因素。認得色料33顏色，就能知悉該組辨識區與螺接件尺寸規格的對應關係，不影響後續的使用。In particular, the size, remembered or not, is an insignificant factor in the present invention. By recognizing the color of the color material 33, the corresponding relationship between the identification area and the size specification of the screw joint can be known, and subsequent use is not affected.

回顧第2圖不難發現，該第四辨識區27有一個寬端與一個窄端，該寬端是圓形，其直徑大於窄端的寬度。某些實施例中，該寬端是多邊形，其寬度大於窄端的寬度，亦在本發明的容許範圍。Looking back at FIG. 2, it is not difficult to find that the fourth identification area 27 has a wide end and a narrow end, and the wide end is circular and its diameter is larger than the width of the narrow end. In some embodiments, the wide end is a polygon, and the width of the wide end is larger than that of the narrow end, which is also within the allowable range of the present invention.

該第四辨識區27由一個載有色料33的凹部30組成，該凹部30陷入本體11的第一表面23。具體而言，該凹部30包括：一個窄溝31與一個寬槽32，該窄溝31一端通到本體11的前端14，另端連到寬槽32。其中，該窄溝31是彎折的，充當第四辨識區27的窄端使用，限制寬槽32避開其他的辨識區。如此，該寬槽32相當於第四辨識區27的寬端。The fourth identification area 27 consists of a concave portion 30 carrying the color material 33 , and the concave portion 30 is recessed into the first surface 23 of the main body 11 . Specifically, the concave portion 30 includes: a narrow groove 31 and a wide groove 32 , one end of the narrow groove 31 is connected to the front end 14 of the main body 11 , and the other end is connected to the wide groove 32 . The narrow groove 31 is bent and used as the narrow end of the fourth identification area 27 to limit the wide groove 32 to avoid other identification areas. In this way, the wide groove 32 corresponds to the wide end of the fourth identification area 27 .

其他辨識區與第四辨識區27大致相同，差異處在於：第一、第二辨識區24、25的窄溝31是彎的，該第三辨識區26的窄溝31是直的。The other identification areas are substantially the same as the fourth identification area 27 , except that the narrow grooves 31 of the first and second identification areas 24 and 25 are curved, and the narrow grooves 31 of the third identification area 26 are straight.

另外，該指示部47是一個載有色料48的角槽49，該角槽49是正三角形或等腰三角形，三角形的一個角落朝向本體11的第一表面23，能夠對齊每個辨識區的窄端。In addition, the indicator portion 47 is a corner slot 49 carrying the color material 48, the corner slot 49 is an equilateral triangle or an isosceles triangle, one corner of the triangle faces the first surface 23 of the main body 11, and can align the narrow end of each identification area .

如第7圖所示，該頭構件10配合一個主體構件51共同組成一把開口扳手50。因為頭構件10具備活動顎，所以開口扳手50又稱為活動式開口扳手。As shown in FIG. 7 , the head member 10 cooperates with a main body member 51 to form an open-end wrench 50 . Since the head member 10 has a movable jaw, the open-end wrench 50 is also called a movable-type open-end wrench.

圖中，該主體構件51有一根桿52，該桿52一端樞接一個接頭53，另端聯結一個結合套58。該結合套58在桿52是固定不動的，用以安裝一個握把55，該握把55靠近結合套58的端部是一個透明罩56，該透明罩56遮蔽一個刻度環561，該刻度環561具備扭力顯示的一組刻度562。In the figure, the main body member 51 has a rod 52 , one end of the rod 52 is pivotally connected to a joint 53 , and the other end is connected to a coupling sleeve 58 . The combination sleeve 58 is fixed on the rod 52 for installing a handle 55, and the end of the handle 55 close to the combination sleeve 58 is a transparent cover 56, the transparent cover 56 covers a scale ring 561, the scale ring 561 has a set of scales 562 for torque display.

當接頭53接收***部19，該基座18阻止***部19過度深入接頭53。該***部19的鋼珠20頂著接頭53的一個按鈕54，使按鈕54浮突於接頭53外部。該按鈕54壓迫鋼珠20退回***部19，允許***部19脫離接頭53。同理，中空的接頭53能夠接收其他頭構件10，完成一個扭矩工具的組裝作業。The base 18 prevents the insert 19 from reaching too far into the connector 53 when the connector 53 receives the insert 19 . The steel ball 20 of the insertion portion 19 pushes against a button 54 of the connector 53 , so that the button 54 protrudes outside the connector 53 . The button 54 presses the steel ball 20 back to the insertion portion 19 , allowing the insertion portion 19 to be disengaged from the joint 53 . Similarly, the hollow joint 53 can receive other head members 10 to complete the assembly of a torque tool.

在第8圖中，該結合套58設置一個扭矩指示單元57。該扭矩指示單元57的一個殼571***於結合套58外表，該殼571結合一個透明蓋574，該透明蓋574遮蔽一個第一色塊575、一個第二色塊576、一個第三色塊577與一個第四色塊578，每個色塊顯示一個扭矩值579。該殼571的一個尖端572指向刻度環561之一刻度562，顯示扭力程度。從尖端572到透明蓋574之間是一個扭矩單位573，該扭矩單位573採用牛頓-米（Nm）的國際單位制，刻印在殼571的表面。In FIG. 8 , the coupling sleeve 58 is provided with a torque indicating unit 57 . A shell 571 of the torque indicating unit 57 protrudes from the outer surface of the coupling sleeve 58, the shell 571 is combined with a transparent cover 574, and the transparent cover 574 covers a first color block 575, a second color block 576, and a third color block 577 With a fourth color patch 578, each color patch displays a torque value 579. A tip 572 of the housing 571 points to a scale 562 of the scale ring 561 to indicate the degree of torsion. From the tip 572 to the transparent cover 574 is a torque unit 573 , in the SI unit of Newton-meter (Nm), imprinted on the surface of the case 571 .

從第2、7、8圖來看，該第一色塊575的顏色相同或近似於第一辨識區24的顏色，以18Nm的扭矩值579轉動尺寸規格為17mm的螺接件是恰當的。既不必背誦，也不需要心算或用電子計算機演算，該扭矩指示單元57通過顏色表達開口扳手50正確的扭矩值。From Figures 2, 7, and 8, the color of the first color block 575 is the same or similar to the color of the first identification area 24, and it is appropriate to rotate the 17mm screw with the torque value 579 of 18Nm. The torque indicating unit 57 expresses the correct torque value of the open-end wrench 50 by color, neither needing to recite, nor to do mental arithmetic or calculation with an electronic computer.

同理，相同或近似顏色的第二色塊576與第二辨識區25，該頭構件10以扭矩值579為42Nm的力轉動尺寸規格為22mm的螺接件較佳。相同或近似顏色的第三色塊577和第三辨識區26，以55Nm的扭矩轉動尺寸規格為26mm的螺接件。或者，顏色相同（或近似）的第四色塊578與第四辨識區27，用65Nm的扭矩轉動尺寸規格為29mm的螺接件比較恰當。Similarly, for the second color block 576 and the second identification area 25 of the same or similar color, the head member 10 is preferably rotated with a torque value 579 of a force of 42 Nm and a screw connection with a size of 22 mm. The third color block 577 and the third identification area 26 of the same or similar color are rotated with a torque of 55Nm and a screw with a size of 26mm. Alternatively, it is more appropriate for the fourth color block 578 of the same (or similar) color to the fourth identification area 27 to rotate a screw with a size of 29mm with a torque of 65Nm.

在第9圖中，一個空調設備70進行組裝或維修作業。一個開口扳手60的一個柄61有一個頭部62，該頭部62立著二個固定顎63，這些固定顎63相向的一面視為嚙合面64，兩個嚙合面64距離是不變的。因此，該開口扳手60是固定式，用兩個固定顎63套住一個螺帽76，該螺帽76在一個銜接管77的端部並靠近一個管接頭72。該管接頭72設在空調設備70的一根管71，藉由一根螺桿75鎖住管接頭72與螺帽76，使管71結合銜接管77。In Fig. 9, one air conditioner 70 is being assembled or repaired. A handle 61 of an open-ended wrench 60 has a head 62, the head 62 stands with two fixed jaws 63, the opposite sides of these fixed jaws 63 are regarded as engaging surfaces 64, and the distance between the two engaging surfaces 64 is constant. Therefore, the open-end wrench 60 is of the fixed type, with two fixed jaws 63 covering a nut 76 at the end of a connecting pipe 77 and close to a pipe joint 72 . The pipe joint 72 is provided on a pipe 71 of the air conditioner 70 , and a screw 75 is used to lock the pipe joint 72 and the nut 76 , so that the pipe 71 is combined with the pipe 77 .

假設，該開口扳手50轉動管接頭72。該管接頭72有六個平面73，至少一個平面73鋪設顏色74。根據同色的配對關係，該活動顎40移到相同（或近似）於顏色74的辨識區，改變嚙合面41到固定顎12的距離。同時，該開口扳手50更改至辨識區同色的色塊扭矩，適合轉動管接頭72，不傷及管接頭72的構造。換句話說，本實施例的開口扳手50比固定式開口扳手60更容易找到合適的扭力。Assume that the open end wrench 50 turns the fitting 72 . The pipe joint 72 has six flat surfaces 73 , and at least one flat surface 73 is covered with a color 74 . According to the matching relationship of the same color, the movable jaw 40 moves to the identification area of the same (or similar) color 74 , and changes the distance between the engaging surface 41 and the fixed jaw 12 . At the same time, the open-end wrench 50 is changed to the color block torque of the same color in the identification area, which is suitable for rotating the pipe joint 72 without damaging the structure of the pipe joint 72 . In other words, the open-end wrench 50 of this embodiment is easier to find a suitable torque than the fixed open-end wrench 60 .

綜合上述說明，本實施例的頭構件具備下列優點：Based on the above description, the head member of this embodiment has the following advantages:

第一、該頭構件組裝主體構件，卸下頭構件，允許主體構件結合其他的頭構件。First, the head member assembles the body member, and the head member is removed, allowing the body member to be combined with other head members.

第二、當活動顎配合固定顎夾持螺接件，不必經過度量衡的演算，就能以活動顎的指示部指向辨識區，通過顏色識別相應尺寸規格的螺接件，操作簡單又方便。Second, when the movable jaw cooperates with the fixed jaw to clamp the threaded parts, the indicator part of the movable jaw can point to the identification area without going through the calculation of weights and measures, and the threaded parts of the corresponding size can be identified by color, which is simple and convenient to operate.

第三、不需要背誦、記憶、心算或電子計算機予以演算，通過顏色識別頭構件轉動螺接件較佳的扭矩值為何。Third, it does not need to recite, memorize, mentally calculate or calculate by computer, and identify the best torque value for the head member to rotate the screw joint by color.

第10圖採用第二表面231的俯視角度，描繪頭構件10'的第二實施例。該頭構件10'的結構大致相同於第一實施例，差異處在於：首先，該本體11的第二表面231添加另組辨識區。Figure 10 depicts a second embodiment of the head member 10' using a top view of the second surface 231. The structure of the head member 10 ′ is substantially the same as that of the first embodiment, and the difference lies in that: first, another set of identification areas is added to the second surface 231 of the main body 11 .

其次，該活動顎40的側面461也有指示部47，該指示部47的尖端指向任一辨識區的窄端，該寬端及∕或辨識區的顏色對應活動顎40至固定顎12的距離，應適用螺接件的尺寸規格，以及該頭構件10'施予合適的扭矩值至螺接件。Secondly, the side surface 461 of the movable jaw 40 also has an indicator portion 47, the tip of the indicator portion 47 points to the narrow end of any identification area, the wide end and/or the color of the identification area corresponds to the distance from the movable jaw 40 to the fixed jaw 12, The dimensions of the screw connections should be applied, and the head member 10' applies an appropriate torque value to the screw connections.
