螺丝批
技术领域
本发明涉及手动工具，具体是一种螺丝批，其带有如同转轮式弹夹的批头架用于安置多个不同形式的批头，使用时可如同转动弹夹一样转动批头架来选用不同形式的批头。
背景技术
现有的螺丝批多为手柄上向前延伸出批杆，批杆前端形成批头或者安装批头。需要使用不同形式的批头工作时需要更换螺丝批或者更换批头，使用不便。 US6134995A 号、 US6138537A 号、 US7028593B1 号专利分别要求保护一种螺丝批，它们均带有类似于转轮式弹夹的批头架用于安置多个不同形式的批头，使用时可如同转动弹夹一样转动批头架来更换不同形式的批头。但它们存在以下缺点：
1 ．结构复杂；
2 ．从批头架更换批头时需将手柄与批头架的安装位置分离，操作不便；
3 ．旋拧螺钉时需要用手柄向前施力顶紧推杆才能对螺钉施加扭矩，推杆易缩回；
4. 所施加的扭矩多受限于手柄与批头架的安装位置的配合结构，由于该配合结构通常为塑料件，因此扭力有限；
5 ．批头架与推杆对应的位置被遮挡，会遮挡使用者的视线，不能准确更换批头；
6 ．不便更换批头架，因此也不便更换批头架上的批头；
7 ．缺少对批头架的定位，推杆不能准确对准批头架上批头安置孔，因此不能顺利的将所需的批头推出。
8 、由于批头的作用是对螺钉施加扭矩，其主体多呈六棱柱状，因此与其配合的批头套筒内孔的形状（主要是用于对批头传递扭矩的部分）应该与批头的形状相配，进一步的，为了能够将批头顺利推出，用于容纳批头的孔（如批头架上的容纳孔、批头套筒的内孔等）多与批头间隙配合，因此在推出批头的过程中，批头的前端（尤其如图 33 所示'一'字形批头的前端，该前端的最大尺寸与批头主体一致）会偏离批头套筒的内孔而难以被推入；进一步的，当批头主体的表面与批头套筒的内孔表面偏离一定角度时，也难以将批头推入批头套筒的内孔；上述不能将批头推入批头套筒的内孔的情形，均会导致螺丝批不能使用。

具体实施方式
以下结合说明书附图通过具体实施例对本发明做进一步说明。本文中'前'用来描述某元件靠近批头套筒 11 一侧的部位，亦即图 1 中的右侧；'后'用来描述该元件与'前'相反的部位，亦即图 1 中的左侧。
图 1 示出了本发明螺丝批的一个较佳实施例的剖面结构，该螺丝批包括：
手柄 1 ，其前端设批头套筒 11 ，在手柄 1 上位于批头套筒 11 后方的位置开设前后延伸的缝 12 以及从缝 12 可视的安装位 13 （见图 29 ） ，在缝 12 的边缘设滑道 14 ，在滑道 14 上的前部设第一定位部 14a （见图 22 ） ；进一步的，参见图 5 -7 ，批头套筒 11 的内孔包括位于前部的扭矩传递段 11a 和位于后部的第一导向段 11b ，第一导向段 11b 的孔壁设成导向面 11c ，具体的，导向面可为圆锥面，该圆锥面使第一导向段 11b 形成锥孔段，锥孔段的后端（图 5 所示的右端）的直径大于其前端（图 5 所示的左端）的直径；为了进一步使批头能够顺利进入批头套筒，批头套筒的内孔包括位于扭矩传递段 11a 与第一导向段 11b 之间并连接扭矩传递段和第一导向段的过渡面 11d ， 过渡面 11d 使得 扭矩传递段 11a 和第一导向段 11b 间基本上平滑过渡，没有明显尖棱；
转轮状批头架 2 （参见图 8 -16 ），其轴向 n-n （即其轴线方向，参见图 1 、图 13 、图 15 -16 ）的转动轴与手柄的前后方向一致（手柄的前后方向定义为与缝 12 、滑道 14 以及下文述及的推杆 3 的延伸方向一致），并可转动地安装在安装位 13 ，其上分布有轴向的容纳有批头 21 的容纳孔 22 ，且容纳孔 22 可转至与批头套筒 11 的内孔轴向对应；进一步的，如图 10 所示，容纳孔 22 的前端（图示右端）设有扩口 22a ，以便收回批头时不阻挡批头，使批头能够顺利内收进容纳孔 22 ；
推杆 3 （参见图 23 、 26 ），其沿前后方向安置于手柄 1 内且轴向对应批头套筒 11 的内孔， 可自第一位置滑动至第二位置 ；
推钮组件 4 （参见图 24 、 25 、 27 、 28 ），其与推杆 3 装配并可滑动地配合在滑道 14 上且可定位于第一定位部 14a ；
当推钮组件 4 定位于第一定位部 14a 时，推杆 3 位于 第一位置， 伸入批头架 2 的一个容纳孔，将该容纳孔内的批头推向批头套筒 11 至该批头伸出批头套筒 11 ，当推钮组件 4 位于滑道 14 上的后部时，推杆 3 位于批头架 2 的后侧。
上述图 1 所示的螺丝批，构成零部件少，结构简单；为使用带来方便。
使用该螺丝批时，用手握持住手柄 1 ，通过转动批头架 2 可将容纳有所需批头的容纳孔转至与推杆 3 对应，此时通过推钮组件 4 将推杆 3 向前推出，推杆 3 前端接触对应容纳孔内的批头，并与批头结合，直至推钮组件 4 定位于第一定位部 14a ，则推杆 3 前端伸入对应的容纳孔，将其中的批头推向批头套筒 11 至该批头伸出批头套筒 11 ， 用于旋拧螺钉。由于批头主体的横截面通常为正六边形，因此批头套筒 11 内孔的横截面亦应为正六边形，以便与批头对应用于传递扭矩；由于推钮组件 4 定位在第一定位部 14a ，因此推杆 3 不能伸缩，此时可通过手柄 1 对推杆 3 施加推力来将批头 21 插入 螺钉头上的槽内，进而旋拧螺钉。由于在批头套筒的内孔设置导向段，推出批头时不会受到阻挡，批头能够顺利进入批头套筒内孔到达工作位置；且基于各种原因导致批头主体的棱角 21a 与批头套筒的内孔角 11e 偏离时（参见图 35 ），可通过该导向面令批头转动适当角度使批头主体的棱角 21a 与批头套筒的内孔角 11e 对应（参见图 34 ），从而能够将批头顺利推入批头套筒内孔到达工作位置。
用毕，可操作推钮组件 4 ， 从第一定位部 14a 解除定位，再顺势将推杆 3 向后拉回至滑道 14 上的后部，直至推杆 3 从对应的容纳孔中缩回而位于批头架 2 的后侧的第二位置，以免障碍批头架的转动，并可将批头套筒 11 中的批头收回批头架上对应的容纳孔。由于在批头架上的容纳孔的前端设扩口，使得收回批头时批头能够顺利进入批头架上的容纳孔。
该螺丝批，使用时通过转动批头架，及操控推钮组件推动或者拉回推杆即可，操作简单。又因其装配了如同转轮手枪上的转轮式弹夹式的批头架，且使用时可如同转动弹夹一样，转动批头架来选用不同形式的批头，批头如同子弹一样被推杆向前推出，因此可称本发明为枪式螺丝批。
使用中，旋拧螺钉时推杆通过推钮组件定位于手柄上的滑道上，推杆不易缩回，所施加的扭矩由批头套筒承受，可承受的扭力较大；通过手柄上的缝可见装配在安装位的批头架，因此可以准确的将需要使用的批头转至与推杆对应，并进一步地用推杆推出。
至此，该实施例的上述结构阐明了本发明的发明构思以及实现本发明的技术特征。但是作为对上述技术方案的进一步完善和补充，该实施例还包括以下技术手段，以便在实施本发明时根据具体作用将它们选用在上段所述的技术方案上。
首先，作为该较佳实施例在手柄 1 前端配置批头套筒 11 的优选技术手段，参见图 3-7 、图 17 -21 ，是在手柄 1 的前端设有棘轮结构 15 ，批头套筒 11 设于棘轮结构 15 上，在棘轮结构 15 上开设连通批头套筒 11 与批头架上的容纳孔的通孔，为保证强度，棘轮结构 15 可用金属材料制成。因此，通过该棘轮结构 15 可实现批头套筒 11 及其内批头的定向转动（顺时针方向转动施加扭矩或者逆时针方向转动施加扭矩），为使用提供方便。具体的，棘轮结构 15 包括棘爪座 15b 、棘轮套 15c 和转套 15d ：棘爪座 15b 固定于手柄 1 的前端而与手柄形成一体，该棘爪座 15b 上设两个反向的可摆动的棘爪 15e 以及用于控制该两个棘爪位置状态的拨件 15f ，拨件 15f 上具有两个分别对应两个棘爪 15e 的拨块 15g ；棘轮套 15c 套在棘爪座 15b 上用于与棘爪 15e 啮合；转套 15d 套在棘爪座 15b 的外侧并与拨件 15f 连接；批头套筒 11 设于棘轮套 15b 上，通孔 15a 开设在棘爪座 15b 上。通过该将批头套筒设于棘轮结构上的结构形式，批头 21 被推杆 2 从批头架的容纳孔经所述通孔 15a 推入批头套筒 11 ， 或者从批头套筒经所述通孔拉回批头架的容纳孔。该棘轮结构，转动转套 15d 时，可以带动拨件 15f 的两个拨块 15g 来改变两个棘爪 15e 的位置状态，进而改变两个棘爪与棘轮套 15c 内棘齿的啮合关系（即换档）来实现工作需求：如图 4 所示状态，此时两个棘爪 15e 同时与棘轮套 15c 的内棘齿啮合，因此无论顺时针方向转动手柄还是逆时针方向转动手柄，均能够将来自手柄的扭矩通过棘爪座 15b 、其中一个棘爪、棘轮套 15c 传递给批头套筒 11 ，以使批头对螺钉施力。当从图 4 所示状态，通过转套 15d 将两个拨块 15g 顺时针方向转动一个角度时，则其中一个棘爪（图中所示上方的一个）被推离棘轮套 15c 、另一个棘爪（图中所示下方的一个）继续与棘轮套 15c 的内棘齿啮合，此时，逆时针方向转动手柄，能够将来自手柄的扭矩通过棘爪座 15b 、与棘轮套啮合的棘爪、棘轮套 15c 、批头套筒 11 传递给批头；顺时针方向转动手柄，则与棘轮套啮合的棘爪可被棘爪座带动，从棘轮套的棘齿上滑过，不向批杆递给扭矩，令手柄回转。当从图 4 所示状态，通过转套将两个拨块 15g 逆时针方向转动一个角度时，则其中一个棘爪（图中所示下方的一个）被推离棘轮套、另一个棘爪（图中所示上方的一个）继续与棘轮套的内棘齿啮合，此时，顺时针方向转动手柄，能够将来自手柄的扭矩通过棘爪座 15b 、与棘轮套啮合的棘爪、棘轮套 15c 、批头套筒 11 传递给批头，逆时针方向转动手柄，则与棘轮套啮合的棘爪可被棘爪座带动从棘轮套的棘齿上滑过，不向批杆递给扭矩，令手柄回转。进一步的，参见图 2 ，转套 15d 的内壁具有三个定位槽 15h ，棘爪座 15b 上设有定位弹子 15i ，该定位弹子 15i 由弹性元件支撑，位于一个定位槽内。从而可以使转套 15d 在周向定位，因此无论转套转至上述三个工作位置的任一位置，均通过定位而将该位置保持。两个棘爪 15e 之间支撑有令该两个棘爪张开靠向所述棘轮套的弹性元件。由此保证棘爪与棘轮套啮合，其通过一个弹性元件是实现了对两个棘爪的支撑，零件少，结构紧凑。
作为该较佳实施例的优选技术手段，在该设置棘轮结构的基础上，如图 5 所示，通孔 15a 的前端（图示左端）设有扩口 15a 1 ，通孔 15a 的后端（图示右端）设成第二导向段 15a 2 ，第二导向段可为圆锥孔，从而使得批头通过该通孔时可以顺利的被推出以及顺利的被收回。当如该段所述在手柄 11 的前端设棘轮结构 15 ，批头套筒 11 设于棘轮结构 15 上时，由于棘轮套 15c 上的内棘齿的数量较多（一般多于 6 个，如 18-36 个），则当棘爪随机的从内棘齿上滑过时（实际使用时就是如此），均会导致图 35 所示的批头主体的棱角 21a 与批头套筒的内孔角 11e 偏离的现象，这种现象必然障碍批头被推进批头套筒的内孔；而当实施本发明所要求保护的将批头套筒 11 的内孔设计出第一导向段 11b 时，则在将批头推向批头套筒 11 内孔的过程中可通过该第一导向段 11b 的导向作用令批头转动适当角度至如图 34 所示使批头主体的棱角 21a 与批头套筒的内孔角 11e 对应，从而能够将批头顺利推入批头套筒内孔到达工作位置。
其次，作为该较佳实施例在手柄前端配置批头套筒 11 的另一种优选技术手段，是在手柄 1 的前端设结构件，批头套筒设于结构件上。如将所述棘轮结构的棘爪座作为结构件，将批头套筒在棘爪座上加工出来即可，或者以所述棘轮结构的带有批头套筒的棘轮套为结构件，将棘轮套设于手柄的前端亦可。这里之所以在手柄的前端设结构件，目的在于增加批头套筒的强度以及便于加工制造，若手柄本身的强度足以可以设置批头套筒来向批头传递扭矩以及有合适的加工方法时，则可在手柄的前端直接加工出批头套筒作为等同技术手段。
该较佳实施例为了使滑道 14 耐磨以及具有足够的强度，滑道 14 （参见图 22 ）为金属件并装配在手柄上。
作为该较佳实施例第一定位部的优选技术手段，第一定位部 14a 为设置在滑道 14 上的缺口（参见图 22 ）。
当第一定位部 14a 为设置在滑道上的缺口时，实现推钮组件 4 在第一定位部 14a 定位的一种优选技术手段是：参见图 23 -25 ，推杆 3 的尾部向滑道的方向延伸出基部 31 ，推钮组件 4 包括锁片 41 、触钮 42 以及弹性元件，锁片 41 沿基部 31 延伸的方向活动地安置在基部 31 且在其活动范围内可卡入缺口和从缺口脱出，弹性元件置于锁片 41 与基部 31 之间用弹力将锁片 41 向缺口内弹压，触钮 42 前后滑动地装配在基部 31 上并在其上设置迫使锁片活动的触动部 43 。如图所示，所述的触动部为两端矮、中间高的圆弧面（也可以为两端矮、中间高的斜面）。如此结构，当如图所示锁片 41 卡在缺口内实现推钮组件 4 在滑道 14 上定位时，用手向后拉触钮 42 ，则可通过触动部 43 压持锁片 41 克服弹性元件的弹力令锁片 41 脱出缺口实现推钮组件 4 在滑道 14 上的解锁，则可顺势将推钮组件 4 在滑道 14 上顺势向后拉回；当将推钮组件 4 拉至下文还要述及的作为第二定位部 14b 的缺口时，锁片 41 则在弹性元件的作用下被弹入该缺口实现对推钮组件 4 的定位。反之，当从作为第二定位部 14b 的缺口向前推动触钮 42 时，推钮组件 4 的动作与从作为第一定位部的缺口向后拉动触钮的情形相同，不再赘述。
当第一定位部 14a 为设置在滑道 14 上的缺口时，实现推钮组件 4 在第一定位部 14a 定位的另一种优选技术手段是：参见图 26 -28 ，推杆 3 的尾部向滑道 14 的方向延伸出基部 32 ，推钮组件 4 包括触钮 44 以及弹性元件，触钮 44 上设置锁止缘 45 ，触钮 44 沿基部延伸的方向活动地安置在基部 32 且锁止缘 45 在触钮的活动范围内可卡入缺口和从缺口脱出，弹性元件置于触钮 44 与基部 32 之间用弹力将锁止缘 45 向缺口内弹压。如此结构，当如图所示锁止缘 45 卡在缺口内实现推钮组件 4 在滑道 14 上定位时，先向下按触钮 44 即可克服弹性原件的弹力令锁止缘 45 从缺口中脱出解除推钮组件在该缺口的定位，之后即可顺势向后拉动触钮 44 将推杆向后拉回；当将推钮组件 4 拉至下文还要述及的作为第二定位部 14b 的缺口时，释放触钮，则触钮 44 在弹性元件的作用下被弹起令锁止缘 45 卡入该缺口实现对推钮组件的定位。反之，当从作为第二定位部的缺口向前推动触钮时，推钮组件的动作与从作为第一定位部的缺口向后拉动触钮的情形相同，不再赘述。进一步的（尤其是针对实现推钮组件在第一定位部定位的后一种技术手段，操作时由于需要按压触钮），在手柄内沿滑道的延伸方向设置有承载推杆的承载部，以便按压触钮时支撑推杆；之所以将承载部沿滑道的延伸方向设置，是因为这样可使推杆沿承载部前后顺畅移动；在实际设置承载部时，可在手柄上对应推杆 3 的下部设置槽状滑道 16 或者在手柄对应延伸部 32 的两侧设置台阶 17 ，在该较佳实施例中，同时具备了槽状滑道 16 和台阶 17 。
为了实现对推钮组件 4 在滑道 14 上的后部定位，在滑道 14 上的后部设置一个对推钮组件定位的第二定位部 14b 。具体的，该第二定位部 14b 的结构可与第一定位部 14a 的结构相同（参见图 26 ）；推杆 3 于推钮组件 4 定位于该第二定位部 14b 时位于批头架 2 的后侧。此外，由于推钮组件定位在第二定位部时不需要承受前后方向的推力（如旋拧螺钉时需要的推力），因此该第二定位部的结构可以为与所述的推钮组件弹性配合的结构或者磁性吸附的结构等用以将推钮组件保持在该第二定位部即可。
为了实现批头架 2 在手柄 1 上的转动以及便于安装和拆下，参见图 8 -16 、图 29 、 30 ，安装位 13 的前壁与批头架 2 的前端以及安装位 13 的后壁与批头架 2 的后端分别设置凹坑 18 和伸缩轴头 24 ，在伸缩轴头 24 的后端支撑弹性元件，伸缩轴头位于对应的凹坑内实现批头架 2 在安装位 13 的安装并能转动。如图所示，伸缩轴头 24 均安装在批头架 2 上，凹坑 18 位于安装位 13 的前壁和后壁，除此情形外，根据需要可以将配合伸缩轴头和凹坑更换位置。
为了实现批头架 2 在手柄 1 上的定位以便推杆 3 能够准确对应批头架 2 上的容纳孔 22 ，参见图 8 -16 、图 30 ，安装位 13 的前壁或 / 和后壁与批头架 2 的前端或 / 和后端分设定位弹子 19 和定位槽 25 ，在定位弹子 19 的后端支撑弹性元件，定位弹子 19 位于定位槽内实现批头架在手柄上的定位。如图所示，定位弹子 19 位于安装位 13 的前壁，定位槽 25 位于批头架 2 的前端边缘，除此情形外，根据需要可将该定位结构设置在安装位的后壁和批头架的后端边缘或者同后端同时设置，结构允许时，还可以更换定位弹子和定位槽的位置。
为了避免容纳孔 22 内的批头 21 脱落，容纳孔 22 的内壁具有弹性结构 26 ，如图所示为在容纳孔 22 的内壁上制成的弹片（参见图 9 -10 、图 15 ）。
为了便于识别容纳孔内批头的形式，批头架 2 上对应每个容纳孔的位置具有批头标记 27 （参见图 8 、图 13 ）；或者将批头架 2 制成透明的以便通过批头架可以识别批头的形状。
为了备用较多的批头，手柄 1 上设有用于存放备用批头架的容纳部 110 （参见图 31 -32 ），或者在手柄 1 上设备用批头存放架 5 。
为了便于握持以及对推杆施加推力，手柄 1 具有向推杆 3 的一侧延伸的握持部 111 （参见图 1 、图 31 、图 32 ），如图所示这样设置的握持部使得整个可顺利推出批头的螺丝批在形状上更像是一把手枪。
作为推杆的前端与批头配合的一种优选技术手段，推杆 3 的前端或 / 和批头 21 上设有供二者相结合的结合结构，推杆 3 于推钮组件 4 位于滑道 14 上的后部时位于批头架 2 的后侧并依靠该结合结构将对应的批头带回对应的容纳孔。鉴于该结合结构，当推杆 3 将批头推至批头套筒 11 内时可以依赖该结合结构避免批头从批头套筒 11 中脱落；拉回推杆的过程也可以依赖该结合结构由推杆将对应的批头带回对应的容纳孔。具体的，该结合结构可以为赋予推杆的前端或 / 和批头的供二者吸附的磁性结构，一般的，由于批头多为标准件且无磁性，因此通过将推杆前端制成磁性件（如在其中置放永磁体）来实现与批头的磁性结合；该结合结构还可以为分设于推杆的前端和批头后端的榫头和榫槽（如在批头后端与推杆前端分别设置如同 US6138537 号专利中述及的结合的榫头 40 和榫槽 144 ）。
作为避免批头干涉批头架转动的优选技术手段，容纳孔的后端具有阻止部 23 ，当依赖前述任一种结合结构将批头拉回容纳孔时批头则被容纳孔后端的阻止部 23 （如台阶）阻止与推杆 3 前端脱离而滞留在容纳孔内，避免露出而干涉批头架的转动；或者批头架的后端与安装位的后壁之间保持缝隙，推杆的前端于推钮组件位于滑道上的后部时对应缝隙，这种情形尤其适用于磁性结合的结合结构，因此当依赖磁性结合的结合结构将批头拉回容纳孔时，即使批头后端伸出容纳孔，则可以通过转动批头架令批头与推杆脱离，将批头滞留在容纳孔内，进一步的，为了避免批头从容纳孔中任意露出，这种情形下可在容纳孔 22 的内壁同时配置前述的弹性结构 26 。
图 36 为本发明的另一个较佳实施例的剖面结构示意图，与前述实施例的手柄握持部 111 为手枪式不同，本实施例的手柄握持部 112 为直柄。当然，本领域的普通技术人员可以理解，本发明也可适用于具有其他形式的手柄的情形。
前述通过实施例方式说明了本发明的发明构思，在具体实施时，并不限于该情形，本发明述及的第一导向段 11b 、导向面 11c 、过渡面 11d 同样可应用到 US6134995A 号、 US6138537A 号、 US7028593B1 号专利所公开的批头套筒上，述及的扩口 22a 同样可应用到 US6134995A 号、 US6138537A 号、 US7028593B1 号专利所公开的批头架上。
以上详细描述了本发明的较佳具体实施例。应当理解，本领域的普通技术无需创造性劳动就可以根据本发明的构思作出诸多修改和变化。因此，凡本技术领域中技术人员依本发明的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可以得到的技术方案，皆应在由权利要求书所确定的保护范围内。
