Description

仿生工具手
本发明属于机械工具领域，尤其涉及一种仿生工具手。
传统扳手只能拧六角螺母，没有抓紧被夹物体的功能，且容易夹伤被夹螺纹使其滑出。现有的扳手的改进有些是在手柄上加装一个手动或微型马达驱动或者采用在手柄上安装滑杆，通过齿轮传动达到快速推动活动爪与固定爪闭合，但也无法解决抓紧被夹物体的功能。且在空间受限制时，扳动一定角度后需将扳口从螺母上取下，返回后重新再夹持，操作麻烦，管钳虽可以拧管状物，但体积笨重，操作麻烦，需两只手来调整，狭窄空间中根本无法使用，且由于管钳上都设有卡齿，在拧管子的时候会出现无法把管子退出来的情况，而且卡齿也容易损伤被夹物体。
本发明实施例的目的在于提供 一种仿生工具手 ，不但可以拧六角螺丝，还可以拧管状物，而且还可以作为夹紧物件的工具使用。
为此，本发明实施例提供了 一种仿生工具手，包括具有固定颚的把手、蜗轮、蜗杆和活动颚，固定颚和活动颚组成夹口，固定颚的夹持面上设有可相对 其滑动的第一楔块，活动颚的夹持面上设有可相对其滑动的第二楔块，第一楔块和第二楔块的大小头方向相反。
相对于现有技术，本发明的优点在于：
易在狭小空间内拧管子或螺丝，加紧效果佳，易退出管子且能防止被夹物体损伤。
图 1 、 2 是本发明第一实施例的仿生工具手的结构示意图；
图 3 、 4 是本发明第一实施例的仿生工具手的使用过程示意图；
图 5 是本发明第二实施例的仿生工具手的结构示意图；
图 6 是本发明第三实施例的仿生工具手的结构示意图。
为了说明本发明所述的技术方案，下面通过具体实施例来进行说明。
如图 1 至 2 所示：一种仿生工具手，包括具有固定颚 11 的把手 1 、蜗轮 2 、和具有蜗杆 32 的活动颚 3 ，固定颚 11 和活动颚 3 组成夹口，固定颚 11 的夹持面上设有可相对其移动的第一楔块 4 。固定颚 11 具有一滑槽 111 ，第一楔块 4 设有可在固定颚 11 的滑槽 111 内移动的第一凸块 42 ，所述第一凸块 42 作为限位结构，所述第一楔块 4 的夹持面的上半截为平面，下半截 41 具有锯齿凹陷槽，活动颚 3 的夹持面 31 为具有平滑坡面凹陷槽。
固定颚 11 与第一楔块 4 之间设有一拉簧 6 ，拉簧 6 一端通过一弯钩钩在固定颚 11 的凸柱 112 上与固定颚 11 连接，另一端通过另一弯钩钩在第一楔块 4 的通孔上与第一楔块 4 连接；拉簧 6 可以保证第一楔块 4 移动后可以复位。在其他实施例中，也可以通过其他弹性结构将滑动的楔块复位，所述弹性结构为拉簧、压簧或弹片，且所述拉簧、压簧或弹片的数量为一个或多个。
仿生工具手还包括一保护罩 5 ，保护罩 5 设有第一导槽 51 、第二导槽 52 和两凸柱 53 。楔块 4 还具有第二凸块 43 ，第一凸块 42 可在保护罩 5 的第一导槽 51 内移动；第二凸块 43 可在保护罩 5 的第二导槽 52 内移动。保护罩 5 可以对楔块 4 进行限位连接和保护，保护罩 5 的凸柱 53 压进固定颚 11 第二凹腔 113 后使保护罩 5 固定在固定颚 11 上，第一导槽 51 、第二导槽 52 与固定颚 11 滑槽 111 相结合，大大提高楔块 4 移动时的平稳性。
当工具手顺时针方向拧管状物时 ( 如图 3 所示 ) ，因第一楔块 4 的夹持面下半截 41 呈锯齿凹陷槽，齿可以陷进管面，牢牢抓住管状物。当工具手用作抓紧物件时，是由活动颚 3 与第一楔块 4 的平面部分夹持，齿面碰不到，因其与被夹物之间的静摩擦系数大于第一楔块 4 与固定颚 11 之间的静摩擦系数，所以第一楔块 4 就会向外滑动；固定颚 11 与第一楔块 4 相接触的面为斜面，该斜面向活动颚 3 方向倾斜，所以第一楔块 4 向外滑动时使扳口变小，在这过程中第一楔块 4 同时把水平拉力转化为抓紧被夹物体的垂直夹力，拉力越大，垂直夹力越大，从而使被夹物体抓得越紧。
当工具手逆时针方向拧管状物时 ( 如图 4 所示 ) ，由于第一楔块 4 向后退，扳口变大，活动颚 3 的夹持面 31 为平滑凹陷坡面，管子向下坡移大，也增加了开口，所以工具手逆时针方向扳动管状物时能非常顺利退出管子。工具手抓物时，要退出物体，只要将工具手向开口方向推动，楔块就会后退，从而增大了开口，被夹物就能顺利被松开。
请参考图 5 ，本发明还提供了第二种仿生工具手，和第一种仿生工具手不同之处在于，不仅固定颚 11 的夹持面上设有可相对其移动的第一楔块 4 ，活动颚 3 的夹持面设有可相对其移动的第二楔块 7 ，第一楔块 4 和第二楔块 7 的大小头方向相反，第二楔块 7 通过具有限位的滑槽 71 滑动，且活动颚 3 和第二楔块 7 之间设有弹性结构，能将滑动的第二楔块复位，所述第一楔块和第二楔块的夹持表面具有凹陷槽、锯齿面或锯齿凹陷槽。
请参考图 6 ，本发明还提供了第三种仿生工具手，仿生工具手的固定颚 11 的夹持面上不设有楔块，固定颚的夹持面上具有凹陷槽、锯齿面或锯齿凹陷槽其中的一种，活动颚 3 的夹持面设有可相对其移动的第二楔块 7 ，第二楔块 7 的大头朝向夹口外侧，小头朝向把手，所述第二楔块与活动颚之间通过具有限位结构的滑槽滑动，且所述活动颚和第二楔块之间设有弹性结构，能将滑动的第二楔块复位。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内 。
