发明内容
针对现有技术中棘轮起子定位力不佳、且无法绝缘的技术问题，本发明提供一种绝缘的多角度棘轮起子。
本发明提供一种绝缘的多角度棘轮起子，包括：一握柄、一弹簧、一压钮、一驱动头与一枢接件，该枢接件外部盖设有一以绝缘材质制成的封盖，所述握柄外露的金属部分、压钮外露的金属部分以及驱动头外露的金属部分上均包覆有一绝缘层，其中：
握柄一端伸出有一结合座，该结合座具有一旋动口，结合座的一侧边设有通过所述旋动口的一第一枢孔与一容槽，该容槽与握柄相邻设置，所述弹簧与压钮能够安装于该容槽中；
压钮具有一第一端与一第二端，在第一端与第二端之间于压钮底缘形成有一闪避缺口，当弹簧与压钮水平放入握柄的容槽，使弹簧撑抵在容槽与压钮的第二端之间，且所述压钮能够内缩，所述闪避缺口对正于旋动口；
驱动头具有一本体部，本体部上设有受控于棘轮装置的一接杆，在本体部相异于接杆伸出的一端上设有一齿轮凸体，齿轮凸体一侧在相连两个凸齿部之间均连接有一挡缘，所述齿轮凸体中央贯穿有一第二枢孔，该驱动头利用齿轮凸体放入握柄的旋动口，使齿轮凸体的第二枢孔能够与旋动口的第一枢孔保持相对，所述枢接件穿置于该第一枢孔和该第二枢孔中，使驱动头借由齿轮凸体在握柄的结合座上获得枢组，所述压钮能够卡入齿轮凸体其中二凸齿部所形成的凹部中，并抵止在挡缘上，所述封盖盖设并封闭第一枢孔。
其中，所述枢接件利用螺锁的方式与握柄的第一枢孔结合。
本发明对照现有技术具有以下优点：
(一)本发明提供绝缘的多角度棘轮起子，其握柄、压钮与驱动头外露的金属部上均包覆有一绝缘层，因此将能达到整只完全绝缘的效果，该在电气环境中使用相对安全。
(二)本发明提供绝缘的多角度棘轮起子，其通过压钮卡入于凹部，配合挡缘的抵止，将能达到多平面的接触，该对于驱动头于卡止后的稳定度具有显著的提升。
