M424220 五、新型說明： 【新型所屬之技術領域】 本創作涉及手工具的收納技術，特別是指一種可 挾持工具的裝置。 【先前技術】 手工具的種類繁多，即使是相同功能的工具，也 會設計出不同的構造，更何況同一工具，亦區分尺寸 的大、小，進而衍生許多工具。這些工具為了容易攜 帶，自然需要合適的收納裝置，譬如工具盒。 已知的工具盒，譬如臺灣證書第M267041號新型 專利案，係將一第一本體樞接一第二本體，彼此相互 閉合或開啟。兩本體分別在相對面設置數道溝槽，槽 内容納一手工具，譬如六角扳手。利用兩對成形於溝 槽開口的擋片，壓制手工具不得任意離開溝槽。 但是，取出手工具使用時，會將擋片往外撐開， 長期使用的結果，導致擋片的壓制作用因為鬆弛而不 再有效，造成手工具在溝槽裡面隨意滑行，甚至跌落 工具盒外。 因此，如何讓手工具維持在工具盒的定位作用， 就成為本創作亟待解決的課題。 【新型内容】 有鑑於此，本創作人深入探討先前技術之問題， 憑藉多年從事相關產業之研發與製造之經驗，積極尋 求解決之道，終於成功地開發出一種可挾持工具的裝 3 M424220 置，以改善習用創作之問題。 本創作主要目的在於：採用挾持的手段，以彈性 結構將工件定位在工具盒内，不因工件離開而損傷挾 持效果，非常簡單和方便。 緣於上述目的之達成，本創作提供一種可挾持工 具的裝置，在一殼體内部形成一中空的腹腔部，可通 過一貫穿殼體的孔洞與外界相通，且孔洞到腹腔部的 途徑設置一彈性件，配合孔洞的壁面挾持一深入腹腔 部的工件。 根據上述技術手段，足以衍生單獨的挾持裝置， 包括： 一構件，以周邊框圍中間部位形成一中空的腹腔 部，可經由一貫穿構件周邊的孔洞而與外界相通，且 孔洞到腹腔部的途徑設置一彈性件； 一殼體，配合構件周邊而圍住腹腔部，卻不會覆 蓋孔洞； 當一工件通過孔洞深入腹腔部，藉由彈性件配合 孔洞的壁面對工件致生拽持作用。 上述技術手段還能衍生摺疊的挾持裝置，包括： 一第一構件與一第二構件，每個構件以周邊框圍 中間部位形成一中空的腹腔部，可經由一貫穿構件周 邊的孔洞而與外界相通，且孔洞到腹腔部的途徑設置 一彈性件； 一第一殼體和一第二殼體，兩殼體樞接在一起而 可摺疊併合，每個殼體配合對應的構件周邊而圍住腹 腔部，卻不會覆蓋孔洞； 4 當一工件通過孔洞深入腹腔部，藉由彈性件配合 孔洞的壁面對工件致生挾持作用。 無論是哪一種挾持裝置，都是讓殼體圍住構件且 遮蔽局部外貌。尤其是彈性件，是成形於構件且彈性 回復的舌片，配合孔洞的壁面對一經過孔洞深入腹腔 部的工件致生挾持作用。 簡單地說，這些孔洞的尺寸不一，容納所需的工 件，譬如起子頭、六角扳手等，可插入孔洞且持續深 入構件的腹腔部，進而推開舌片。該舌片對工件施予 反作用力，配合孔洞的壁面形成挾持作用，足以讓工 件定位在殼體且停止不動。工件抽出後，舌片因為本 身彈性而回復原狀，仍可持續使用，簡單又方便。 以下，基於圖式詳述相關實施例之目的、構造及 特徵，相信本創作採用之技術、手段及功效，當可由 之得一深入而具體的瞭解。 【實施方式】 請參閱第1圖，在一第一殼體10樞接一第二殼體 20，兩殼體10、20同為多邊形體，以樞接處為軸心往 外展開。其中，該第一殼體10的上、下方分別隆起一 排突出段31，每排有四個直徑不一的突出段31，與對 邊整排的突出段31彼此相對。在第一殼體10的角落 突出一對樞耳11、13，每個樞耳11、13貫穿一樞孔 12，且柩耳13框圍樞孔12的壁厚處沿半徑方向剖開 一缺口 14。 該第二殼體20的上、下方分別隆起一排突出段 M424220 41，每排有六個直徑不一的突出段41，與對邊整排的 突出段41彼此相對。在第二殼體20的角落隆起一凸 部21，該凸部21凹凸配合於兩枢耳11、13之間，兩 端依轴向各自延伸一短軸22、23，其中之一短軸22 插入樞耳11的樞孔12裡面，另根短軸23通過缺口 14進入枢耳13的樞孔12中。該第二殼體20在凸部 21的對邊成形一扣部24。 在第2圖中，這些突出段3 1、41的軸心部位各自 貫穿一孔洞32、42，孔徑大小互異且直觀透視另端， 進而發現兩殼體10、20内部藏有若干彈性件。此外， 靠近樞耳11的突出段31成形一鈎合部34，其長度超 出第一殼體10。靠近凸部21的突出段41亦成形一鈎 合部44，其長度雖然不及鈎合部34，卻能隨著兩殼體 10、20展開至最大角度而與鈎合部34彼此相扣，使 兩殼體10、20維持在展開型態。 在本實施例所述之彈性件，是指舌片33、43，具 體構造容後詳述。 接著看到第3圖，第二殼體20相對第一殼體10 略微提起，讓凸部21予以傾斜，使短軸23從缺口 14 離開樞耳13的樞孔12。同時，順勢抽離樞耳11内部 的短軸22，即可取得獨立的兩殼體10、20，譬如第4 圖。 圖中，獨立的第一殼體10，可拆卸取得一第一構 件30。該第一構件30中間部位成形一中空的腹腔部 35，被第一殼體10遮蔽局部外貌為常態，令上、下兩 排突出段31能夠露出殼外。該第一構件30的腹腔部 6 M424220 3通5往成:36，規劃成四個經由上、下孔洞Μ m-工間°各隔片36兩端鄰接第—構件30處 —保持斜立狀態的舌片33，這些舌片33兩 對设置在洞口到腹腔部35的途徑中。每對舌片 33在相向^之間保持適當的距離，可在單—舌片 叉力擺動時’避免對面的舌>5 33觸碰干擾。另外，中 空的第-殼體10在内壁成形一對肋條15,結第一 構件30的組裝構造，可參考以下的說明。”M424220 V. New description: [New technical field] This creation involves the storage technology of hand tools, especially a device that can hold tools. [Prior Art] There are many types of hand tools, and even the same function tools will be designed with different structures, not to mention the same tools, which also distinguish between large and small sizes, and thus many tools. These tools naturally require a suitable storage device, such as a tool box, for easy carrying. A known tool box, such as the Taiwan Patent No. M267041, is a new type of first body that is pivotally connected to a second body and is closed or opened to each other. The two bodies are respectively provided with a plurality of grooves on opposite sides, and the slots are provided with a hand tool such as a hex wrench. With two pairs of flaps formed in the slot opening, the pressing hand tool must not leave the groove arbitrarily. However, when the hand tool is taken out, the flap is opened outward. As a result of long-term use, the pressing action of the flap is no longer effective because of slack, causing the hand tool to slide freely inside the groove or even fall outside the tool box. Therefore, how to maintain the positioning of the hand tool in the tool box has become an urgent problem to be solved in this creation. [New content] In view of this, the creator has in-depth discussion of the problems of prior art. With years of experience in R&D and manufacturing of related industries, he actively sought solutions and finally succeeded in developing a 3 M424220 device that can hold tools. To improve the problem of custom creation. The main purpose of this creation is to use the means of holding, to position the workpiece in the tool box with elastic structure, and not to damage the holding effect due to the leaving of the workpiece, which is very simple and convenient. Due to the above object, the present invention provides a device for holding a tool, and a hollow abdominal cavity portion is formed inside a casing, and can communicate with the outside through a hole penetrating through the casing, and a hole is provided to the abdominal cavity portion. The elastic member cooperates with the wall surface of the hole to hold the workpiece deep into the abdominal cavity. According to the above technical means, it is sufficient to derive a separate holding device, comprising: a member, forming a hollow abdominal cavity portion around the middle portion of the peripheral frame, which can communicate with the outside through a hole penetrating the periphery of the member, and the hole to the abdominal cavity portion An elastic member is disposed; a casing encloses the abdominal cavity portion around the member but does not cover the hole; when a workpiece passes through the hole and penetrates into the abdominal cavity portion, the elastic member cooperates with the wall of the hole to cause the workpiece to hold the holding action. The above technical means can also derive a folding holding device, comprising: a first member and a second member, each member forming a hollow abdominal cavity portion at a middle portion of the peripheral frame, which can communicate with the outside through a hole penetrating the periphery of the member The same, and the hole to the abdominal cavity is provided with an elastic member; a first casing and a second casing, the two casings are pivotally connected together and foldable and merged, and each casing is enclosed by the corresponding component periphery The abdominal cavity does not cover the hole; 4 When a workpiece passes through the hole and penetrates into the abdominal cavity, the elastic member cooperates with the wall of the hole to face the workpiece. Regardless of the type of holding device, the housing is surrounded by the member and shields the local appearance. In particular, the elastic member is a tongue which is formed on the member and elastically recovers, and the wall of the matching hole faces the workpiece which passes through the hole and penetrates into the abdominal cavity to cause a holding action. Simply put, these holes are of different sizes and accommodate the required work pieces, such as a screwdriver bit, a hex wrench, etc., which can be inserted into the hole and continue deep into the abdominal cavity of the member, thereby pushing the tongue apart. The tongue exerts a reaction force on the workpiece, and the wall surface of the hole forms a holding action, which is sufficient for the workpiece to be positioned in the casing and stopped. After the workpiece is taken out, the tongue is restored to its original shape due to its elasticity, and it can be used continuously, which is simple and convenient. Hereinafter, the purpose, structure and characteristics of the related embodiments will be described in detail based on the drawings, and it is believed that the techniques, means and effects adopted by the present invention can be understood in detail. [Embodiment] Referring to Fig. 1, a second housing 20 is pivotally connected to a first housing 10. The two housings 10, 20 are both polygonal and extend outward from the pivot. The upper and lower portions of the first casing 10 are respectively raised with a row of protruding segments 31, and each row has four protruding segments 31 of different diameters, and the protruding segments 31 of the entire row are opposite to each other. A pair of pivoting ears 11 and 13 are protruded from a corner of the first housing 10, and each of the pivoting ears 11 and 13 extends through a pivot hole 12, and a gap is formed in the radial direction of the wall thickness of the frame hole 12 of the tab 13 14. The upper and lower portions of the second casing 20 are respectively raised with a row of protruding portions M424220 41, and each row has six protruding segments 41 of different diameters, and the protruding segments 41 of the entire row opposite to each other are opposed to each other. A convex portion 21 is embossed at a corner of the second casing 20, and the convex portion 21 is concave-convexly fitted between the two pivoting ears 11, 13 respectively. Each of the two ends extends axially outwardly with a short shaft 22, 23, one of which has a short axis 22 Inserted into the pivot hole 12 of the pivot 11 and the other stub shaft 23 enters the pivot hole 12 of the pivot 13 through the notch 14. The second casing 20 is formed with a buckle portion 24 on the opposite side of the convex portion 21. In Fig. 2, the axial portions of the protruding segments 3, 41 are each penetrated through a hole 32, 42 having mutually different aperture sizes and visually seeing the other end, and it is found that a plurality of elastic members are housed inside the two housings 10, 20. Further, the protruding portion 31 near the pivot 11 is formed with a hook portion 34 whose length exceeds the first housing 10. The protruding portion 41 near the convex portion 21 also forms a hook portion 44, which, although not as long as the hook portion 34, can be engaged with the hook portion 34 as the two housings 10, 20 are deployed to the maximum angle. The two housings 10, 20 are maintained in an expanded configuration. The elastic members described in this embodiment are referred to as tongues 33 and 43, and the specific constructions are detailed later. Next, as seen in Fig. 3, the second housing 20 is slightly lifted relative to the first housing 10, causing the projection 21 to be tilted so that the stub shaft 23 is separated from the notch 14 by the pivot hole 12 of the pivot 13 . At the same time, the outer two housings 10, 20 can be obtained by withdrawing the short shaft 22 inside the pivot 11 as shown in Fig. 4. In the figure, a separate first housing 10 is detachably provided with a first member 30. A hollow abdominal cavity portion 35 is formed in the middle portion of the first member 30, and the partial appearance of the first casing 10 is shielded to be normal, so that the upper and lower rows of the protruding segments 31 can be exposed outside the casing. The abdominal cavity portion 6 M424220 of the first member 30 passes through 5 to 36, and is planned to be four through the upper and lower holes Μ m-work. The two ends of the spacers 36 are adjacent to the first member 30. The tongues 33, two pairs of these tongues 33 are disposed in the way of the opening to the abdominal cavity 35. Each pair of tabs 33 maintains an appropriate distance between the opposing faces, and can avoid the opposite tongue > 5 33 touch interference when the single-to-tab force swings. Further, the hollow first casing 10 is formed with a pair of ribs 15 on the inner wall, and the assembly structure of the first member 30 can be referred to the following description. ”
如第5圖所示’第二殼體2〇圍住一第二構件4〇 的腹腔部45,用以遮蔽局部外貌。除了突出段41的 數目比第-殼體還多，可在腹腔部45規劃出對應的空 間以外’其餘諸如：上、下兩排突出段41外露、以隔 片46將腹腔部45規劃成經由孔洞42出入外界的通 道、，片46兩端分別與舌片43共同成形於第二構件 4〇、每對舌片43相向端之間保持適當的距離…等構 造，均與第一構件30相同。As shown in Fig. 5, the second casing 2 encloses the abdominal portion 45 of a second member 4''''''''''' In addition to the number of protruding segments 41 being larger than the first-shell, a corresponding space can be planned outside the abdominal cavity portion 45. [The rest of the upper and lower rows of protruding segments 41 are exposed, and the abdominal cavity portion 45 is planned with the spacer 46 via The hole 42 enters and exits the external passage, and both ends of the piece 46 are formed together with the tongue piece 43 to form a proper distance between the opposite ends of the pair of tongue pieces 43 and the opposite ends of each pair of tongue pieces 43, and are the same as the first member 30. .
#圖中的第二殼體20，在内壁成形一對肋條25，卡 入第二構件40圍在腹腔部45的壁面，阻止第二構件 4〇受力頂出第二殼體2〇。再看到第4圖，鈎合部料 阻止第二構件4〇持續深入第二殼體2〇裡面。 如此，單獨使用任一殼體10、20，屬合理的使用 範圍。當然，兩殼體10、20之一受損後，更換新的構 件，就能再次重組使用。至於重組的手段，可參考第 3圖’並依前述拆解流程反向操作即可。 如第6圖所示，重新組合的兩殼體1〇、2〇，受力 相向併合，以第二殼體20的扣部24卡住第—殼體1〇 7 M424220 對應的角落，維持在摺疊狀態。 在第7圖中，一起子頭T插入上排突出段31之一 孔洞32中。起子頭T的插入端為六角柱形體，對角的 直線距離小於孔徑，得以自由出入突出段31，進而持 續深入第一構件30的腹腔部35，推動對應的舌片33 由斜立虛線位置偏移到實線方位。舌片33受力偏擺的 同時，對起子頭T的插入端施予反作用力，使其略微 偏斜地接觸孔洞32的壁面。如此一來，起子頭T被彈 性的舌片33配合孔壁予以挾持，即能隨時定位在第一 殼體10内。 手指夾住起子頭T往外抽出。失去壓制力量的舌 片33，依彈性從實線位置回歸虛線方位，仍舊擁有挾 持作用，等待再次使用，非常簡單和方便。此刻的第 一構件30，因框圍腹腔部35的壁面受阻於肋條15， 故不會隨著起子頭T的抽出而離開第一殼體10。 在第8圖中，合併的第一、第二殼體10、20可依 突出段31、41的孔洞32、42大小，容納合適的起子 頭T。 根據上述構造，可以衍生其他實施例。譬如第9、 10圖，同樣以殼體50遮蔽構件60局部外貌為常態， 構成獨立式可挾持工具的裝置。 構件60周邊界定第一端面61與第二端面62,旁 邊支持兩端面61、62的壁面視為兩側壁63，共同框 圍構件60.中間部位且形成中空的腹腔部64，令殼體 50包住腹腔部64周圍卻不會覆蓋兩端面61、62。 兩端面61、62之間成形五個隔片65。這些隔片 8 2介於兩側壁63之間，彼此相 出俨心μ— 出段67’這些突 二^ 端面&、&外表’同時環繞在孔洞 另和構件60在腹腔部64各空間到對應的孔洞 66的途禮設置彈性的舌片⑽，每片舌片⑽依角度斜 ^地成形於側壁6 3 <隔片6 5端部與端面61、6 2相鄰 处。換句話說’構件60的腹腔部64規劃六道， 經由上、下孔洞66出入對應的空間，故每道空；有一 對舌片68 ’這些舌片68相向端彼此保持適當距離， li片τ。68之一受力擺動期間，不會觸碰干擾另- 这個獨立的裝置’與前述實施例的差異在於：如 第11、12圖所示’第—端面61面積大於第二端面62, 使第一端面61周圍超過側壁63與隔片65的部份可以 抵住殼體5G邊緣。同時，殼體％内壁突出兩對梯形 的卡簞。P 5卜因應殼體5〇套在構件6〇的動作，依斜 面順勢通過第二端面62外表，直賴邊的平面頂住第 二端面62内壁為止，對殼體5〇離開構件⑼形成阻礙 效果。如此，這個獨立的裝置就能夠在任一孔洞6 6插 入合適的起子頭，藉由舌片68配合孔洞66壁面予以 挾持。 上述貫施例僅為說明本創作，非為限制本創作。 熟習此技藝者從上述實施例衍生之各種變化、修改與 應用均在本創作之範嘴内。 【圖式簡單說明】 第1圖是立體圖’表現本創作可挾持工具的裝置 第一較佳實施例的屐開情形。 、义 第2圖是平面圖，表現第1圖可挾持工具的裝置 俯視情形。 第3圖是剖視圖’表現第2圖A-A線剖開後的内 部構造。 第4圖是立體圖，表現第1圖可挾持工具的裝置 拆卸後的分解狀態。 弟5圖是剖視圖，表現第4圖B-B線剖開後的内 部構造。 第6圖是平面圖，表現第1圖可挾持工具的裝置 併合後的俯視情形。 第7圖是剖視圖，表現第6圖C-C線剖開後的内 部構造。The second casing 20 in the figure is formed with a pair of ribs 25 formed on the inner wall, and the second member 40 is engaged around the wall surface of the abdominal cavity portion 45 to prevent the second member 4 from being forced out of the second casing 2''. Referring again to Fig. 4, the hooking member prevents the second member 4's from continuing deep into the second casing 2''. As such, the use of either housing 10, 20 alone is a reasonable range of use. Of course, after one of the two housings 10, 20 is damaged, the new component can be replaced and reused. As for the means of reorganization, refer to Figure 3 and reverse the operation according to the above disassembly process. As shown in Fig. 6, the two housings 1〇 and 2〇 are recombined, and the force is opposite to each other, and the buckle portion 24 of the second housing 20 is engaged with the corresponding corner of the first housing 1〇7 M424220, and is maintained at Folded state. In Fig. 7, a sub-head T is inserted into one of the holes 32 of the upper row of projections 31. The insertion end of the screwdriver bit T is a hexagonal cylindrical body, and the diagonal straight distance is smaller than the aperture, and is free to enter and exit the protruding section 31, thereby continuing deep into the abdominal cavity portion 35 of the first member 30, and pushing the corresponding tongue piece 33 from the oblique vertical dotted line position. Move to the solid line. While the tongue piece 33 is biased by the force, a reaction force is applied to the insertion end of the bit T, so that it slightly contacts the wall surface of the hole 32. In this way, the screwdriver bit T is held by the elastic tongue piece 33 in cooperation with the hole wall, so that it can be positioned in the first casing 10 at any time. The finger grips the screwdriver head T and pulls it out. The tongue 33, which loses its strength, returns to the dotted line orientation from the solid line position by elasticity, and still has a holding effect, waiting for reuse, which is very simple and convenient. At this moment, the first member 30 is blocked from the rib 15 by the wall surface of the frame surrounding the abdominal cavity portion 35, so that it does not leave the first casing 10 with the extraction of the bit T. In Fig. 8, the merged first and second housings 10, 20 can accommodate a suitable driver bit T depending on the size of the holes 32, 42 of the projections 31, 41. Other embodiments may be derived from the above construction. For example, in Figures 9 and 10, the partial appearance of the shielding member 60 of the housing 50 is also normal, and a device for holding the tool independently is constructed. The periphery of the member 60 defines a first end surface 61 and a second end surface 62, and the wall surface supporting the end surfaces 61, 62 is regarded as two side walls 63, and the intermediate portion is formed in the middle portion and forms a hollow abdominal portion 64, so that the housing 50 is wrapped. The circumference of the abdominal cavity portion 64 does not cover the both end faces 61, 62. Five spacers 65 are formed between the two end faces 61, 62. These spacers 8 2 are interposed between the two side walls 63, and are mutually out of each other. The out-of-slices 67' are formed in the space of the abdominal cavity portion 64 while surrounding the hole and the member 60 at the same time. Elastic tongues (10) are provided to the corresponding holes 66, and each of the tongues (10) is formed obliquely to the side wall 6 3 < the end of the spacer 65 is adjacent to the end faces 61, 62. In other words, the abdominal cavity portion 64 of the member 60 is planned to be six passages, and the upper and lower holes 66 are inserted into the corresponding spaces, so that each of the spaces is empty; there is a pair of tongues 68' which are opposite ends of each other at an appropriate distance, the li piece τ. When one of the 68 is subjected to the force swing, the interference is not touched - the independent device' differs from the foregoing embodiment in that the area of the first end face 61 is larger than the second end face 62 as shown in Figs. A portion of the first end face 61 that extends beyond the side wall 63 and the spacer 65 may abut the edge of the housing 5G. At the same time, the inner wall of the housing % protrudes from the two pairs of trapezoidal clicks. P 5 depends on the action of the casing 5〇 on the member 6〇, and passes through the outer surface of the second end surface 62 according to the slope, and the plane of the side faces the inner wall of the second end surface 62, which hinders the separation member (9) of the casing 5 effect. Thus, the separate device can be inserted into a suitable driver bit in any of the holes 66, and the tongue 68 can be held in engagement with the wall of the hole 66. The above examples are only illustrative of the creation, and are not intended to limit the creation. Various changes, modifications, and applications derived from the above-described embodiments by those skilled in the art are within the scope of the present invention.
