套筒扳手广泛应用于各种场合。 现有技术的套筒扳手其结构是在扳手体 的两端部， 分别设有单一的套筒孔， 一般是将扳手和一组套筒统一放在一个 盒子里， 使用时将扳手取出套上套筒， 当遇到不同^ ^尺寸的工件时， 需要 有各种不同规格尺寸的套筒扳手， 施工作业时， 要携带多件的套筒扳手， 这 样携带和使用都不方便， 而且也使套筒扳手的成本增加。
针对这一问题 * 出现了一种多头套筒扳手， 即将多个不同规格的套筒集 成在一起， 如中国专利局授权的公告号为 CN201519920U的专利文献公开了一 种多头套筒扳手， 其结构包括扳手体， 扳手体上镶嵌有磁铁扣， 扳手体的两 端安装有套筒头， 扳手体的两端分别设有 U型槽， 在 U型槽壁上设有圆孔， 套 筒头成十字型， 端头设有不相同的套筒孔， 套筒头两端设有圓孔， 圓孔内设 有轴销， 轴销安 型槽壁上的圓孔内， 套筒头绕销轴在扳手体的 U型槽内 转动， 套筒头一端面上圆孔外与套筒孔对应处分别设有 V型槽， 在 U型槽壁的 一内侧上设有小孔， 小孔与槽壁上的圓孔轴线呈 7。夹角， 小孔内设有弹簧和钢 球， 此结构解决了成本高和携带不便.的技术问题， 但此结构没有棘轮的紧凑 性和使用灵活方便' !·生。
棘轮机构是由棘轮和棘爪组成的一种单向间歇运动机构。 棘轮机构常用 在各种机床和自动机中间歇进给或回转工作台的转位上， 也常用在千斤顶上。 在自行车中棘轮机构用于单向驱动， 在手动绞车中棘轮机构常用以防止逆转 β 在机械中常用外啮合式棘轮机构， 它由主动摆杆， 棘爪， 棘轮、 止回棘爪和 机架组成。 主动件空套在与棘轮固连的从动轴上， 并与驱动棘爪用转动副相 联。 当主动件顺时针方向摆动时， 驱动棘爪便插入棘轮的齿槽中， 使棘轮跟 着转过一定角度， 此时， 止回棘 棘轮的:齿背上滑动。 当主动件逆时针方 向转动时， 止回棘爪阻止棘轮发生逆时针方向转动， 而驱动棘爪却能够在棘 轮齿背上滑过， 所以， 这时棘轮静止不动。 因此， 当主动件作连续的往复摆 动时， 棘轮作单向的间歇运动。
