技术领域
本发明涉及一种扳手，特别涉及一种可调式扳手。
背景技术
现有的可调式扳手通常为一体成型的L型，包括长臂和短臂，一般长臂和短臂形成90°的夹角。但由于长臂和短臂之间通过销轴连接，使得长臂和短臂之间的夹角不能调节，因而不能维持特定角度下的使用，限制了该扳手的应用范畴。
还有一些利用枢轴将长臂和短臂连接在一起的可调式扳手，其长臂和短臂的角度可以随意变动。然而，现有的具有换向功能的可调式扳手，为了保证足够的扭力，通常体积比较大，因而不方便在活动空间较小的地方运动，而为了减小体积，又会使扳手扭力不足。

具体实施方式
图中所标示之X、Y、Z系相互垂直。
图1至图4B显示了本发明的第一实施例中的可调式扳手，该可调式扳手包括：第一臂30、棘轮组件20及第二臂10。棘轮组件20以可旋转关系与第一臂30组接，其中棘轮组件20包括换向部件和推动部件。
其中，棘轮组件20被配置为：当换向部件处于第一位置时，推动部件能够在第一方向上使第一臂30转动；当换向部件处于第二位置时，推动部件能够在第二方向上使第一臂30转动；第一方向与第二方向互为反方向。
第二臂10以可旋转关系与棘轮组件20相互组接。棘轮组件20能够以第一旋转轴向A作为轴心而相对于第二臂10转动，第一臂30能够以第二旋转轴向B作为轴心而相对于棘轮组件20沿第一方向或第二方向转动，第一旋转轴向垂直于第二旋转轴向。其中第一方向或第二方向指的是以第二旋转轴向B为轴心的逆时针方向或顺时针方向。
其中，第二臂10的前端具有第一枢接孔11，用以供枢接组件40枢设于其中。在其它实施例中，第二臂也可以与所述棘轮组件为一体成形。
本实施例中，换向部件为滚珠24。棘轮组件20包括第一基座21、第二基座22及外壳23，其中，第一基座21具有第一穿孔211、至少第一长槽212及至少一个固定块213，第一穿孔211开设在第一基座21的中央位置，以供第一臂30贯穿于其中。第一长槽212则开设在第一基座21的表面，以供对应的滚珠24置入滚动于其中。较佳地，可在第一基座21的第一穿孔211的相对二侧分别开设第一长槽212，使此二个第一长槽212相互对应且分别可供滚珠24置入于其中，但不以此为限。固定块213自第一基座21表面凸出，固定块213可以是圆柱体。较佳地，以四个固定块213环形排列在第一穿孔211周围，但不以此为限。
第二基座22组接在第一基座21表面，第二基座22具有第二穿孔221、至少一个第二长槽222、至少一个固定孔223及多个弧形壁224。第二穿孔221同样开设在第二基座22的中央位置，以供第一臂30贯穿于其中。第二长槽222开设在第二基座22的底面且与第一基座21的第一长槽212相互对应。固定孔223开设在第二基座22的底面且与固定块213相互对应，且固定孔223与固定块213的形状及数目相互匹配。多个弧形壁224自第二基座22的表面延伸而出并且围绕在第二穿孔221周围，这些弧形壁224之间分别具有滑槽225，以供对应的推动部件置入于滑槽225之中。本实施例中，推动部件为滚针25，呈圆柱形，但不以此为限。另外，第二基座的外侧周围开设至少一个开口226，且开口226与第二长槽222相互通连。
外壳23的一侧分别延伸出有第一部231及第二部232，第一部231及第二部232之间形成枢接槽233，用以供第二臂的一端置入于其中。第一部231及第二部232分别具有贯穿的第二枢接孔234，并使第二臂10的第一枢接孔11与第二枢接孔234相互对应，以供枢接组件40贯穿枢接于其中。外壳23内部形成第一容置槽235及第二容置槽236，第一容置槽235的体积较小于第二容置槽236的体积，并且第一容置槽235与第二容置槽236的组成形状匹配于第二基座22的形状，用以供第二基座22组装于其中。
如图5A所示，第一容置槽235内壁面形成有多个弧曲面237，以供对应的滚针25滚动接触其面。如图6A所示，第二容置槽236具有多个限位槽238，以供对应的滚珠24置入于其中。另外，外壳23具有第三穿孔239，第三穿孔239开设在外壳23的中央位置且与第一容置槽235相互通连，以供第一臂30贯穿于其中。
当棘轮组件20于组装时，先将滚珠24置放在第一基座21的对应第一长槽212中，再将第二基座22的多个固定孔223套在第一基座21的对应固定块213上，使固定块213与固定孔223可通过干涉固定方式，令第一基座21与第二基座22相互组接。即可使第二基座22的第二长槽222对应盖合在第一长槽212上，令第一长槽212与第二长槽222之间形成通道，以供对应的滚珠24在第一长槽212与第二长槽222之间滚动位移，并可滚动露出于第二基座222的开口226外。接着，再将多个滚针25装配在对应的滑槽225之中。
之后，再将外壳23套在第二基座22之上。具体地，将第二基座22组入于外壳23的内部，使得多个弧形壁224及其滚针25可装在第一容置槽235之中，并使滚针25接触于对应的弧曲面237。而第二基座22本体则装在第二容置槽236之中，至少两个滚珠24可通过开口226定位于对应的限位槽238内。如此，即可完成棘轮组件20的整体组装。
最后，再将第二臂10嵌入外壳23之枢接槽233中，使得外壳23之第一部231及第二部232分别位于第二臂10的相对二侧，并以枢接组件40穿设对应的第一枢接孔11及第二枢接孔234，以此将第二臂10枢接在外壳23上，使棘轮组件20和第一臂30能够以第一旋转轴向A作为轴心而相对于第二臂10转动。
如图1及图4B所示，枢接组件40可以是螺丝结构，对应的第一枢接孔11及第二枢接孔234可以是螺孔结构，若要调整棘轮组件20相对于第二臂10的使用角度，即可先松开枢接组件40后，将棘轮组件20调整到所需要的使用角度，再将枢接组件40重新锁紧即可以第二臂10来操作第一臂30。
第一臂30的一端具有枢轴部31，另一端则具有扳动部32。枢轴部31匹配第一穿孔211、第二穿孔221及第三穿孔239的形状，使得枢轴部31可被枢接于棘轮组件20之中。而扳动部32则可为内六角扳手形状，但不以此为限，扳动部32的形状可以是一字型、十字H型、十字Z型、梅花型、四角型、三翼型、翼形十字型、蛇眼型、单向螺丝型、双六角型、八角型、布里斯托型等。
如图5和图6所示，在使用时，转动第一基座21，使得分别位于第一长槽212和第二长槽222中的两个滚珠24相对于外壳23的内壁移动，直至两个滚珠24转至其中两对应的限位槽238中，相应地，三个滚针25分别接触在对应的三个弧曲面237上，且靠近于对应的弧曲面237的其中一端点处。此时，实施者转动第二臂10，即对第二臂10施加扭力，该扭力通过外壳23的弧曲面237及第二基座22的弧形壁224对滚针25发生作用，使滚针25挤压第一臂30，从而对第一臂30施加扭力，带动第一臂30能够在第一方向上转动，而在第二方向上不能转动。
当转动第一基座21，使得两个滚珠24转至另外两个限位槽238中，相应地，三个滚针25靠近于对应的弧曲面237的另一端点处。此时，实施者转动第二臂10，即对第二臂10施加扭力，该扭力通过外壳23的弧曲面237及第二基座22的弧形壁224对滚针25发生作用，使滚针25挤压第一臂30，从而对第一臂30施加扭力，带动第一臂30能够在第二方向上转动，而在第一方向上不能转动。
本实施例通过滚珠24位于不同的位置，使得第一臂能够在不同方向上转动，实现了单向离合器的功能。另外，本实施例中，由于外壳23的弧曲面237具有比常规的弧曲面更大的曲率，因而具有更大的楔角阻碍滚针沿弧曲面的滚动，从而增大了扭力。
如图7A图、图7B及图8所示，本第二实施例的具体实施方式与前述第一实施例大致相同，以下仅就相异之处加以说明，其余相同处不再赘述。
枢接组件40具有头部41、多个卡齿42及弹簧43。其中，头部41设置在枢接组件40的一端且露出于第二部232外。多个卡齿42以间隔排列方式设置在枢接组件40的相对二侧边，如图8所示，以侧视图的枢接组件40为中心，将多个卡齿42环列设置在枢接组件40的圆周围。如图7B所示，弹簧43的二端分别抵持在头部41与多个卡齿42之间。另外，第二臂10的第一枢接孔11的形状及外壳23的第二枢接孔234的形状同样匹配多个卡齿42的形状，使得多个卡齿42可以卡接在对应的第一枢接孔11及第二枢接孔234内。
当枢接组件40于组装时，先将枢接组件40的多个卡齿42对准于第一枢接孔11及第二枢接孔234并卡入于其中，而弹簧43的二端则分别抵持在头部41与其中一侧的卡齿42上。由于多个卡齿42与第一枢接孔11及第二枢接孔234相互卡接固定，所以无法调整棘轮组件20相对于第二臂10的使用角度。若要调整棘轮组件20相对于第二臂10的使用角度，则可先按压头部41，让枢接组件40的多个卡齿42退出第一枢接孔11及第二枢接孔234，并使弹簧43被挤压后弹性变形，从而解除多个卡齿42的卡接状态。接着，将棘轮组件20调整到所需要的使用角度，再释放按压头部41的力量，通过弹簧43的弹性回复力，将多个卡齿42重新卡入对应的第一枢接孔11及第二枢接孔234，再次固定住棘轮组件20与第二臂10之间的使用角度。
另外，在本实施例中，枢接组件40的各卡齿42之间分别以30゜的角度相互间隔排列，当操作棘轮组件20相对于第二臂的使用角度时，可以调节第一臂30与第二臂10之间的角度，例如呈现90゜、120゜、150゜或180゜，但不以此为限。当第一臂30与第二臂10之间的角度为90゜时，可作为常规的扳手型态。当第一臂30与第二臂10之间的角度为180゜时，则可作为类似螺丝起子的型态。
如图9-11所示，本第三实施例的具体实施方式与前述第一实施例大致相同，以下仅就相异之处加以说明，其余相同之处不再赘述。
棘轮组件50包括外壳51、底座54及顶盖55。其中，外壳51与底座54相互组接，外壳51的上半部位开设有至少一个第一限位槽511及至少一个第二限位槽512。在本实施例中，将二个第一限位槽511分别开设在外壳51的相对二侧，而二个第二限位槽512同样的分别开设在外壳51的相对二侧，并使并使第一限位槽511的开设位置高于第二限位槽512的开设位置，且第一限位槽511的数目及第二限位槽512的数目不以上述为限。本实施例中，换向部件为滚珠56，当上下移动外壳51时，滚珠56的位置能够在第一限位槽511和第二限位槽513之间变换，即在第一位置和第二位置之间变换。外壳51的内部分别形成第一容置槽513、第二容置槽514及第三容置槽515，第一容置槽513形成在外壳51内部的上半部位，并使第一容置槽513与第一限位槽511及第二限位槽512相互通连。第二容置槽514及第三容置槽515则形成在外壳51内部的下半部位，且第二容置槽514与第三容置槽515相互通连，且第二容置槽514的体积较小于第三容置槽515的体积。本实施例中，推动部件包括第一棘齿件52、第二棘齿件53、第一棘齿端面516和第二棘齿端面517。第一棘齿件52及顶盖55组装于第一容置槽513中。第二棘齿件53被安装于第二容置槽514中，底座54被安装于第三容置槽515中。
再者，第一容置槽513的一端形成第一棘齿端面516，并使第一棘齿端面516的数目及方向匹配于第一棘齿件52。而第二容置槽514的一端同样形成第二棘齿端面517，并使第二棘齿端面517的数目及方向匹配于第二棘齿件53。
第一棘齿件52具有第一穿孔521，第一穿孔521开设在第一棘齿件52的中央位置，以供第一臂30贯穿于其中。同样的，第二棘齿件53具有第二穿孔531，第二穿孔531开设在第二棘齿件53的中央位置，以供第一臂30贯穿于其中。
当滚珠56位于第一位置时，第一棘齿件52与第一棘齿端面516配合，使得第一臂能够在第一方向上被带动而发生转动；当滚珠56位于第二位置时，第二棘齿件53与第二棘齿端面517配合，使得第一臂能够在第二方向上被带动而发生转动。
顶盖55的一侧分别延伸出有第一部551及第二部552，第一部551及第二部552之间形成枢接槽553，用以供第二臂10的一端置入于其中。第一部551及第二部552分别具有贯穿的第二枢接孔554，并使第二臂10的第一枢接孔11与第二枢接孔554相互对应，以供枢接组件40贯穿枢接于其中。顶盖55的另一侧则延伸有嵌块555，嵌块555的外形匹配第一容置槽513的形状，并且嵌块555开设有至少一个球槽556，以供对应的滚珠56置入滚动于其中。较佳地，可在嵌块555的四个侧边分别开设有球槽556，使此四个球槽556相互对应且分别可供滚珠56置入于其中，但不以此为限。
底座54与外壳55相互组接，且底座54具有第三穿孔541，第三穿孔541开设在底座54的中央位置，以供第一臂30贯穿于其中。而顶盖55具有第四穿孔557，第四穿孔557开设在顶盖55的中央位置且与第一容置槽513相互通连，以供第一臂30贯穿于其中。
当棘轮组件50于组装时，将第一棘齿件52置入于外壳51的第一容置槽513内部，再将顶盖55的嵌块555组入于第一容置槽513内，并使球槽556内的滚珠56先露出在对应的第一限位槽511中。接着，再将第二棘齿件53组入于外壳51的第二容置槽514内，并使底座54组装在第三容置槽515中。如此，即可完成棘轮组件50的整体组装。
最后，再将第二臂10嵌入顶盖55之枢接槽533中，使得顶盖55之第一部551及第二部552分别位于第二臂10的相对二侧，并以枢接组件40穿设对应的第一枢接孔11及第二枢接孔554，以此将第二臂10枢接在顶盖55上，令棘轮组件50以第一旋转轴向A作为轴心而相对于第二臂10转动。
第一臂30的一端具有枢轴部31，另一端则具有扳动部32。枢轴部31匹配第一穿孔521、第二穿孔531、第三穿孔541及第四穿孔557的形状，使得枢轴部31可被枢接于棘轮组件50之中。而扳动部32则可为内六角扳手形状，但不以此为限，扳动部32的形状可以是一字型、十字H型、十字Z型、梅花型、四角型、三翼型、翼形十字型、蛇眼型、单向螺丝型、双六角型、八角型、布里斯托型等。
在使用时，通过上下移动外壳51，使得滚珠56进入不同的限位槽中，比如，向下移动外壳51，使得滚珠56进入位于下方的第二限位槽513中，此时第一棘齿件52与第一棘齿端面516配合，此时实施者转动第二臂10，即对第二臂10施加扭力，该扭力通过外壳51传递给第一棘齿件52和第一棘齿端面516，第一棘齿件52和第一棘齿端面516相互挤压，从而挤压第一臂30，对第一臂30施加扭力，使得第一臂30能够在第一方向上被带动而发生转动，而在第二方向上发生打滑，不能转动。
当向上移动外壳51，使得滚珠56进入位于上方的第一限位槽511中，此时第二棘齿件53与第二棘齿端面517配合，此时实施者转动第二臂10，即对第二臂10施加扭力，该扭力通过外壳51传递给第二棘齿件53与第二棘齿端面517，第二棘齿件53与第二棘齿端面517相互挤压，从而挤压第一臂30，对第一臂30施加扭力，使得第一臂30能够在第二方向上被带动而发生转动，而在第一方向上发生打滑，不能转动。
本实施例通过滚珠56位于不同的位置，使得第一臂能够在不同方向上转动，实现了单向离合器的功能。另外，由于棘齿件与棘齿端面接触面积较大，且只有轴向力，没有其它方向的分力，从而提高了扭力。
以上的实施方式详细描述了本发明的几种具体实施例。应当理解，本发明所属技术领域的人员在了解了本发明上述的技术构思、具体实施例和功效，可以根据本发明的技术构思作出诸多的修改和变化。因此，依据本发明的上述技术构思在现有技术的基础上通过逻辑分析、推理或者有限的实验从而获得的技术方案，皆应在本发明的权利要求书所请求的保护范围内。
