Description

工具的扳动装置 技术领域 本发明关于一种扳动装置， 特别是指一种工具的扳动装置， 可供使用者反复 连续操作使用。 背景技术
手工具为日常生活当中用以操作旋转对象的工具， 不论其设计为何种形态， 均具有一握柄部以及一工作部， 以供操作者握持于握柄部， 而以工作部套固对象； 其中， 以扳手旋转对象进行锁紧或旋松卸除等作业， 为广泛使用的手工具之一， 而扳手大致上又可分为固定式扳手以及非锁定式扳手。 现有用于固定螺栓、 螺帽或油管锁紧的扳手结构， 包含有固定扳手及非锁定 式扳手， 其中非锁定式扳手可调整其夹颚开口的大小， 以配合螺帽的尺寸， 不论 是固定扳手及非锁定式扳手， 在将扳手依照旋紧或旋松的方向将螺栓、 螺帽或油 管锁紧或放松达一定角度后， 都必须将扳手的夹颚端从螺栓、 螺帽或油管退出， 将扳手在离开螺栓、 螺帽或油管的状态下， 回复至再次便于旋动的角度， 接着， 再将扳手的夹颚端穿置过螺栓、 螺帽或油管， 进行下一次旋紧或旋松的旋动， 此 一动作必须一再重复， 直到将螺栓、 螺帽或油管完全旋紧或旋松。 然而， 此种操作方式对操作者而言造成不便， 且需要额外空间， 以容许扳手 在离开螺栓、 螺帽或油管的状态下回复至再次便于旋动的角度， 还影响工作效率 以及其进度。 有鉴于此， 本案发明人以多年相关产品的研发设计经验， 针对上述存在的缺 点进行研发改良， 并经多方探讨并试做样品试验， 及多次修正改良， 乃推出本发 明工具的扳动装置， 而不需反复分离、 结合等动作即可完成螺锁固定或旋松卸除 的操作。 发明内容
本发明主要目的是提供一种扳动零件时不需要反复地结合、 脱离， 以致于使 用上相当顺手、 效率高、 可连续操作工具的扳动装置。 为了达成上述的目的与功效， 本发明工具的扳动装置包括一工具柄、 一摆动 颚以及一滑动颚， 其中： 该工具柄， 其一端设有一工作头， 且该工作头一端设有一关节座， 该关节座 一侧设有导引壁；
该摆动颚为 L型构件， 其外侧转折处对应关节座设有一套枢于关节座的摆动 槽， 该摆动槽槽底面限制摆动颚相对关节座的转动间距， 且该摆动颚设有一贯穿 摆动槽的滑槽； 以及该滑动颚， 其设有一可相对滑槽滑动设置的滑动部， 由摆动颚与滑动颚 之间构成一套口， 且该滑动部一端对应导引壁设有一推动壁； 如此， 操作工具柄顺向转动时， 摆动颚受到工作头顶部抵顶， 摆动颚与滑动 颚两者呈锁定状态， 并以套口一同夹固对象进行旋紧或旋松作业， 而逆向转动时 摆动颚相对关节座转动， 同时以导引壁推抵推动壁， 以令滑动颚的滑动部在滑槽 朝向摆动颚的相反方向位移， 并扩大套口前后尺寸差， 而上述位移量、 扩大套口 前后尺寸差同等于转动间距， 且扩大的套口得以相对物件空转。
本发明工具的扳动装置进一步包括有下列技术特征， 其中： 1.关节座设有一 贯穿关节座的枢孔， 而摆动槽两侧槽壁各设有一向外贯穿的通孔， 并以一枢轴穿 枢通孔与枢孔， 提供摆动颚相对关节座的摆动。 2.工作头设有关节座的另一端设 有一向外侧延伸的挡止臂。 3.该滑槽垂直截面上窄下为圆形截面结构， 且滑动颚 的滑动部垂直截面也为上窄下为圆形截面的相对结构。 4.该摆动颚底部设有一与 滑槽相连通的贯孔， 贯孔穿设有一凸柱， 而滑动颚在滑动部设有推动壁的另一端 设有一活动槽， 且活动槽开口与贯孔相连通， 而凸柱顶端滑设于活动槽内， 并以 一弹簧两端分别弹抵凸柱以及活动槽朝向推动壁方向的槽面， 滑动颚的滑动部在 滑槽朝向摆动颚的相反方向位移过程中， 凸柱压缩弹簧， 并以弹簧恢复力推抵滑 动颚复位， 同时摆动颚一并复位。 5.于滑动颚设有一缺口， 该缺口位于推动壁上 方， 该缺口供导引壁上端闪避。 6.推动壁上 位置高于导引壁上 位置。
因此本发明可说是一种相当具有实用性及进步性的发明， 相当值得产业界来

具体实施方式
为了详细说明本发明所能达成上述目的与功效， 以下列举一实施例， 关于其 组件结构与组件之间的组配关系， 请配合参阅附图图 1至图 5所示， 图中显示本 发明工具的扳动装置包括有一工具柄 1、 一摆动颚 2以及一滑动颚 3， 其中： 该工具柄 1， 其一端设有一工作头 11 (在此以可相对工具柄 1转动的工作头 11为例， 也可为工作头 11 固定于工具柄 1一端的形态）， 且该工作头 11 一端设 有一关节座 12， 该关节座 12设有一贯穿关节座 12的枢孔 121， 该关节座 12—侧 设有一导引壁 13， 在工作头 11设有关节座 12的另一端设有一向外侧延伸并呈片 状结构的挡止臂 14 ; 该摆动颚 2为 L型构件，其外侧转折处对应关节座 12向内凹设有一套枢于关 节座 12的摆动槽 21， 该摆动槽 21槽底面限制摆动颚 1相对关节座 12的转动间 距， 该摆动槽 21 两侧槽壁各设有一向外贯穿的通孔 211， 并以一枢轴 22穿枢通 孔 211与枢孔 121， 提供摆动颚 2相对关节座 12的枢设摆动， 且该摆动颚 2朝向 挡止臂 14的一端设有一贯穿摆动槽 21 的滑槽 23， 且该滑槽 2 3垂直截面上窄下 为圆形截面的结构设计， 该摆动颚 2底部设有一与滑槽 23相连通的贯孔 231， 该 贯孔 2 31内穿设有一凸柱 24， 且该凸柱 24顶部穿设于滑槽 23 ;
以及该滑动颚 3， 其底端设有一可相对滑槽 2 3滑动设置的滑动部 31， 且该滑 动颚 3的滑动部 31其垂直截面也为相对滑槽 23上窄下为圆形截面的相对结构， 并由摆动颚 2与滑动颚 3之间构成一套口 41， 且该滑动部 31 —端对应导引壁 1 3 设有一推动壁 32， 且推动壁 32与导引壁 1 3相互靠抵， 在滑动部 31设有推动壁 32的另一端设有一活动槽 33， 且该活动槽 33开口与贯孔 231相连通， 而凸柱 24 顶端滑设于活动槽 33内， 并以一弹簧 34设置于活动槽 33内， 且该弹簧 34两端 分别弹抵凸柱 24以及活动槽 33朝向推动壁 32方向的槽面，在滑动颚 3设有一缺 口 35， 该缺口 35位于推动壁 32上方， 该缺口 35供导引壁 1 3上端闪避。
关于本发明动作方式请参阅附图图 4至图 5所示： 操作工具柄 1顺向转动时 (由关节座 12朝向工具柄 1方向转动， 如第四图所示）， 由于摆动颚 2受到工作 头 1 1顶部抵顶， 因此摆动颚 1与滑动颚 3两者呈锁定状态， 并以摆动颚 1与滑动 颚 3的套口 41一同夹固物件 50 (在此以螺帽为例） 进行旋紧或旋松作业；
而逆向转动时 （由工具柄 1朝向关节座 12方向转动， 如第五图所示）， 此时 滑动颚 3不受工具柄 1的工作头 11顶部抵顶，使得滑动颚 3—同与摆动颚 1相对 关节座 12转动， 同时以导引壁 13推抵推动壁 32， 以令滑动颚 3的滑动部 31在 滑槽 23朝向摆动颚 2的相反方向略微位移， 并扩大套口 41前后尺寸差， 而上述 滑动颚 3位移量、 扩大套口 41前后尺寸差同等于转动间距， 且扩大的套口 41尺 寸大于对象最大尺寸， 而使得套口 41得以相对对象 50空转， 提供使用者反复连 续操作使用， 有效提高工作效率及工作进度， 如此达成本发明的目的与功效。
而滑动颚 3的滑动部 31在滑槽 23朝向摆动颚 2的相反方向位移过程中， 凸 柱 24压缩弹簧 34， 并借由弹簧 34恢复力推抵滑动颚 3复位， 同时摆动颚 2—并 复位。
值得一提的是， 本发明推动壁 32上 位置高于导引壁 13上 位置， 使得导 引壁 13得以顺利导引并抵顶推动该滑动颚 3的推动壁 32， 确实推抵滑动颚 3相 对摆动颚 2的滑移动作。
由上所述者仅用以解释本发明的较佳实施例， 并非企图具以对本发明作任何 形式上的限制， 因此， 凡有在相同的发明精神下所做有关本发明的任何修饰或变 更者， 都仍应包括在本发明意图保护的范畴内。
综上所述， 本发明工具的扳动装置其实用性及成本效益上， 确实是完全符合 产业上发展所需， 且所揭露的结构发明也是具有前所未有的创新构造， 所以其具 有新颖性应无疑虑， 又本发明可较现有的结构更具功效的增进， 因此也具有进步 性。
