Description

多向曲杆螺丝刀
技术领域
本发明属于五金工具用具领域,具体是指一种多向曲杆螺丝刀。
背景技术
螺丝刀是人们日常生活和工作操作中离不了的一种工具用具,主要用来上卸螺钉或螺栓,它一般由手柄和直杆状的刀杆组成,刀杆的外端是一字型或十字形的刀头以适应不同刀口形状的钉帽,刀杆和手柄处在同一条轴线上,在使用时也要求这个轴线对正螺钉的轴线一边扭转螺丝刀手柄一边向螺钉施加一个压力保证螺丝刀刀头与螺钉钉帽的可靠对接,如果操作工具的空间较大这种螺丝刀可以对正螺钉来上卸使用起来很方便,而如果操作工具的空间受到限制比如空间狭小难以容纳整根的螺丝刀,此时的工具使用就很困难,虽可勉强的将刀头对准钉帽,但因空间狭小的限制无法做到螺丝刀的轴线和钉杆的轴线处于同一条轴线上,这样就无法可靠的传递旋转力矩,不能正常操作,为了方便此种情况下人们的生活和生产就需要一种可以将螺丝刀的直杆变换为可以弯曲的曲杆的螺丝刀以适应较狭小的操作空间。
发明内容
本发明的目的便是提供一种螺丝刀的新的技术方案多向曲杆螺丝刀,它可以满足上述需要。
本发明的技术方案是这样实现的,它包括刀头、轴承、金属软轴、曲杆、主手柄、辅手柄,所述曲杆为直角形弯曲的两段状,在曲杆的右端连接着一段金属软管,金属软轴从金属软管内穿过与主手柄连接。
本发明的有益效果是:可以多方向弯曲的传递扭力。
附图说明:
图1是本设计螺丝刀的正视图(含刀头部位及曲杆、金属软管连接处的半剖放大视图)。
图中,1为刀头,2为轴承,3为金属软轴,4为曲杆,5为辅手柄,6为金属软管,7为主手柄。
具体实施方式:
下面结合附图来举例说明本设计。
如图1所示,在刀头1和主手柄7之间由一根金属软轴3连接起来,金属软轴穿套在一根呈直角状弯曲为两段的管状曲杆4内,在含有凸台的刀头1的下端和曲杆4的上端面之间装置有一压力轴承2,在曲杆4的水平段装置着辅手柄5;在曲杆4的右端连接着一段金属软管6,金属软轴3从金属软管6内继续穿过与主手柄连接起来。具体使用时,双手分别握住主手柄7、辅手柄5,将刀头对正螺钉钉帽部位的刀口且施加一个压紧力以防止脱位,旋转主手柄,扭力力矩就会通过金属软轴传递到另一端的刀头,轴承也会助力这种传递而不会发生阻滞,如图所示,曲杆末段后的金属软管可以在三维空间里多向多角度自由调整摆向,即它可以根据需要赋予主手柄一个宽裕且得力的旋转操作空间和角度,从而在较狭窄的操作空间里完成常见直杆螺丝刀不能完成的上卸螺钉的工作操作。
