具体实施方式
以下仅以实施例说明本发明可能的实施例，然并非用以限制本发明所欲保护的范畴，事先声明。
请参考图1至6，其显示本发明的一较佳实施例，本发明的棘轮扳手包括本体1、驱动件2、制动件3、切换件4及弹抵组件5。
本体1设有第一容室11、平行于第一容室11的第二容室12、连通第一容室11与第二容室12的第三容室13，第二容室12的两端，其中一端为大径段121、另一端为小径段122。
驱动件2可转动地设于第一容室11内且沿外周面设有第一卡掣部21。于本实施例中，第一卡掣部21例如可具有复数外齿，驱动件2的内周面包含有作动部，于本实施例中，该作动部例如可为一具有多角形的贯穿孔，于其他可能实施例中，该作动部亦可为一具有多边形的凸部，该作动部可供例如与一螺帽或套筒等零件组配。
制动件3设于第三容室13内且设有一与第一卡掣部21相卡掣的第二卡掣部31，第二卡掣部31可限制驱动件2的转动方向。于本实施例中，第二卡掣部31对应于第一卡掣部21的形状且例如可设有复数外齿。
切换件4可转动地设于第二容室12，包括转动件41及延伸于转动件41的凸块42，转动件41容设于大径段121，凸块42容设于小径段122，转动件41远离凸块42的一端径向设有一供拨弄的拨动件43，转动件41径向设有容孔44，当转动件41旋转时，转动件41可以凸块42为轴心而顺畅地转动。较佳地，大径段121与小径段122之间形成一第一阶部61，转动件41与凸块42之间形成第二阶部62，第一阶部61与第二阶部62相抵顶，以将转动件41稳定地定位于大径段121。
弹抵组件5一端容置于转动件41的容孔44、另一端与制动件3互相限位地相抵接，并弹顶制动件3朝向第一卡掣部21。
其中，通过调整切换件4切换制动件3与第一卡掣部21相卡掣的 位置，以调整驱动件2的转动方向。于本实施例中，如图7所示，当切换件4切换至一第一位置时，制动件3受弹抵组件5的抵顶并与驱动件2例如沿一第一方向互相制动(如图7的箭头方向所示)，使驱动件2无法沿第一方向转动；如图8所示，当切换件4切换至一第二位置时，制动件3受弹抵组件5的抵顶并与驱动件2例如沿一第二方向互相制动(如图8的箭头方向所示)，使驱动件2无法沿第二方向转动。
具体而言，于本实施例中，弹抵组件5包括弹性件51及抵块52，弹性件51套设于抵块52且容设于容孔44。进一步的说，抵块52为E型块，抵块52包括套脚521并延伸设有位于该套脚521两侧的挡臂522，弹性件51套设于套脚521，两挡臂522可滑动地容设于容孔44，以使抵块52可滑动。容孔44包括扩大部441及两分别位于该扩大部441两端的延伸段442，两挡臂522分别位于两延伸段442中，弹性件51及套脚521位于扩大部441内，以防止弹性件51脱离切换件4。
制动件3远离第一卡掣部21的一端设有凹孔32，抵块52远离切换件4的一端抵顶于凹孔32的孔壁，以有效防止抵块52脱离制动件3。
值得一提的是，转动件41径向朝制动件3的方向设有缺口部45，转动件41于缺口部45的相对上方形成凸缘46，缺口部45包括凸部451及位于凸部451两侧的弧面段452，其中以转动件41的轴向看，凸缘46的径向尺寸大于凸部451的径向尺寸，容孔44设于凸部451，当切换件4转动时，凸缘46形成一上支撑部，凸块42形成一下支撑部，可分别支撑住切换件4的上下两端，以抵抗拨动切换件4时所产生的上下旋转的力道，可使切换件4转动更顺畅，以及防止切换件4跳脱第二容室12。
综上，本发明的棘轮扳手，当转动件旋转时，转动件可以凸块为轴心而顺畅地转动，大径段与小径段之间形成第一阶部，转动件与凸块之间形成第二阶部，第一阶部与第二阶部相抵顶，以将转动件稳定地定位于大径段，以提高棘轮扳手的使用寿命及工作效率。
当切换件转动时，凸缘形成一上支撑部，凸块形成一下支撑部，可分别支撑住切换件的上下两端，以抵抗拨动切换件时所产生的上下旋转的力道，可使切换件转动更顺畅，以及防止切换件跳脱第二容室。
以上所述是本发明的较佳实施例及其所运用的技术原理，对于本领 域的技术人员来说，在不背离本发明的精神和范围的情况下，任何基于本发明技术方案基础上的等效变换、简单替换等显而易见的改变，均属于本发明保护范围之内。
