图 2为沿图 1中 A-A线的剖视图。
图 3为沿图 1中 B-B线的剖视图。
图 4为沿图 1中 C-C线的剖视图。
图 5为本发明实施例的棘轮螺丝刀的部件分解图。 具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
如图 1-5所示，为本发明的棘轮螺丝刀的一个实施例。该棘轮螺丝刀，包括控制杆 1、 棘轮杆 2以及换向罩 3。
所述控制杆 1的前部 11连接外界的手柄或者直接可供使用者使用，控制杆 1的后部 12 中空， 与棘轮杆 2以及换向罩 3连接。 棘轮杆 2的前部为一棘轮 21， 其外表面上具有棘齿， 所述棘轮 21插入至该控制杆 1的后部 12中并且可在控制杆 1的后部 12内绕其自身的轴旋 转， 棘轮杆 2的后部为一连接部 22连接外部的螺丝刀头。 换向罩 3套于该控制杆 1的后部 12外侧， 所述棘轮杆 2的棘轮 21下方、 即棘轮 21与连接部 22之间设有一台阶面 25， 所述 换向罩 3的底部就位于所述台阶面 25上以定位所述换向罩 3的轴向位置。
所述控制杆 1的后部 12外表面上一侧，设有两个连通至其中空的中心的开口 121，该 开口 121内从内到外分别容置有棘轮片 23以及弹簧 24， 所述棘轮片 23露出位于所述开口 121的内侧并且其内侧端与控制杆 1的后部 12内的棘轮 21相配合，所述棘轮片 23的外侧端 露出于所述开口 121外侧位于所述换向罩 3的内表面，所述弹簧 24使棘轮片 23具有始终向 内的趋势。 所述弹簧 24与控制杆 1的后部 12外侧的换向罩 3之间还设有一弹簧座 4， 所述 弹簧座 4上设有两个向控制杆 1的中心突出、 即向内突出的固定块 41， 所述弹簧 24就套于 所述固定块 41外侧并且一端抵于所述弹簧座 4上。
并且如图 3、 5所示， 该棘轮片 23的上端较下端宽， 所述开口 121与所述棘轮片 23的 形状相匹配， 所述棘轮片 23上端的外侧端露出于所述开口 121位于所述换向罩 3的内表 面， 所述棘轮片 23的内侧端露出于所述幵口 121与所述棘轮 21相匹配， 所述换向罩 3的内 表面上与所述棘轮片 23的外侧端相匹配的位置设有两个控制凹槽 31， 所述棘轮片 23的外 侧端就容置于该控制凹槽 31内， 并且随着换向罩 3在控制杆 1的后部 12的外侧向一侧转 动， 所述控制凹槽 31的一端部就会抵住所述棘轮片 23的外侧端， 使棘轮片 23的内侧端向 内抵住棘轮 21， 使得该棘轮杆 2只能相对于控制杆 1作一个方向的单向的转动。 当换向罩 3向另一侧转动时， 棘轮杆 2只能相对于控制杆 1作另一方向的单向转动。 进而实现控制 杆 1和棘轮杆 2之间的单向转动的锁定， 防止在使用螺丝刀时， 随着控制杆 1的转动棘轮 杆 2也随之回转， 提高了拧紧螺钉的效率。 例如， 如图 3所示， 当换向罩 3旋转至左侧的 控制凹槽 31卡住棘轮片 23的外侧端， 该棘轮片 23的内侧端向内卡住棘轮 21， 此时棘轮可 以相对于所述控制杆 1顺时针转动， 因为棘轮 21顺时针转动时棘轮片 23可压缩弹簧 24， 而当棘轮 21相对于控制杆 1逆时针转动时， 由于棘轮片 23的作用使得棘轮 21无法转动， 反之亦然。
优选地，所述控制杆 1的后部 12外表面上另一侧，设有一沿所述控制杆 1的径向向内 延伸的盲孔 122， 所述盲孔 122内从内向外依次容置复位弹簧 123以及钢珠 124， 所述复位 弹簧 123使得所述钢珠 124具有始终向外侧突出的趋势。 所述换向罩 3的内表面上设有与 所述钢珠 124相匹配的、 沿所述换向罩 3的内表面周面间隔分布的定位孔 32。 当换向罩 3 在控制杆 1外侧转动时，所述钢珠 124卡入定位孔 32内以定位所述换向罩 3在控制杆 1外转 动的位置， 该定位孔 32的位置与换向罩 3的控制凹槽 31的位置相配合， 使得该换向罩 3控 制棘轮杆 2相对于控制杆 1的单向转动的档位更加明显。
并且为了使控制杆 1和棘轮杆 2之间的轴向位置固定不相互移动， 所述控制杆 1的后 部 12的外表面上还设有一容置一锲形块 5的孔 (图中未示出)，该孔通向所述后部 12内的棘 轮 21， 并且所述棘轮 21与棘轮杆 2的后部连接部 22之间设有一圈向内凹的卡圈 26， 如图 5 所示， 该锲形块 5的内侧端就卡于所述卡圈 26内， 使得控制杆 1的后部 12与棘轮杆 2之间 的轴向位置予以确定。 并且为了防止棘轮杆 2和换向罩 3之间相互脱出移位， 该锲形块 5 的外侧还设有一弹簧片 6， 所述弹簧片 6也可以不设于锲形块外侧， 只要弹簧片 6位于换 向罩 3与控制杆 1的后部 12之间即可， 该弹簧片 6使换向罩 3与控制杆 1的后部 12之间具有 张力， 进而使得换向罩 3与控制杆 1的后部 12之间不相互脱出。 这样的结构可以防止控制 杆 1和棘轮杆 2以及换向罩 3产生轴向位移， 使得装配后的棘轮螺丝刀结构更加牢固不易 松脱。 所述卡圈 26位于上述放置换向罩 3底部的台阶面与所述棘轮 21之间。
该棘轮螺丝刀， 不但结构简单， 而且安装方便， 易于加工， 而且可以实现棘轮杆相 对于控制杆的单向转动，防止拧紧螺丝过程中的回转，使该棘轮螺丝刀的使用效率更高， 更便于使用。
尽管以上详细地描述了本发明的优选实施例，但是应该清楚地理解，对于本领域的 技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内所作的任 何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
