Description

助力螺丝刀
技术领域
    本实用新型属于手动工具技术领域,具体涉及一种助力螺丝刀。
背景技术
    目前仍有很多机器安装要求使用手动螺丝刀,传统的手动螺丝刀由于力矩小,拧紧费力,且力度难把握,松动或滑牙现象时有发生。中国专利ZL201020261658.5《一种省力螺丝刀》,公布了一种在抓柄上设置凹槽和连接轴,将助力杆通过连接轴旋转连接在抓柄内的技术方案,增加了助力力臂,达到使用省力的有益效果,但是在抓柄上设置凹槽和连接轴,制造工艺较繁杂,且助力杆长度受限,不方便根据实际需要拆装更换。
实用新型内容
针对现有技术中存在的缺陷,本实用新型的目的在于设计提供一种既使用便捷省力,又拆装更换方便的助力螺丝刀。
助力螺丝刀,包括刀杆、刀柄和助力杆,刀杆与刀柄固定连接,其特征在于所述的助力杆为凹槽结构,凹面向下,槽宽不小于刀杆直径,包括底板和侧板,底板左端设置与刀杆相配合的缺口,侧板左端设置一对圆孔,刀杆相应设置一对圆孔,与助力杆销接固定。
进一步的,所述的助力杆右端设置“C”型卡簧。
进一步的,所述的助力杆槽宽等于刀杆直径。
本实用新型结构简单,设计合理,凹槽设计的助力杆销接在刀杆上,右端设置卡簧,既使用省力,又方便收纳或拆装,是一款值得大面积推广的产品。
附图说明
图1为本实用新型结构示意;
图2为本实用新型助力杆仰视图;
图3为本实用新型卡簧结构示意图;
图中:1-刀柄;2-助力杆;3-卡簧;4-刀杆。
具体实施方式
以下结合说明书附图对本实用新型作进一步详细说明。
如图1-3所示,本实用新型的助力螺丝刀,包括刀杆4、刀柄1和助力杆2,刀杆4与刀柄1固定连接,所述的助力杆2为凹槽结构,凹面向下,槽宽不小于刀杆4直径,优选等于刀杆4直径,包括底板和侧板。底板左端设置与刀杆4相配合的缺口,侧板左端设置一对圆孔,刀杆4相应设置一对圆孔,与助力杆2销接固定。助力杆2右端设置“C”型卡簧3。使用时将助力杆2向上旋转至与刀杆4垂直,底板卡牢固定,助力杆2增加了助力力臂,达到了省力效果,解决了大规格的平头螺丝安装时拧紧费力,力度难把握,容易松动或滑牙等问题。不使用时,将助力杆2向下旋转至与刀杆4平行,既可以通过侧板与刀杆4卡接固定,又可以通过卡簧3与刀杆4卡接固定,闭合后不会振动,不占空间,便于携带。助力螺丝刀整体制造方便,可根据需求,在刀杆4不同位置设置销接圆孔,连接不同长度的助力杆2。
以上所述及图中所示仅为本实用新型的较佳实施例,并不用于限制本实用新型的保护范围,反在本实用新型的构思原则之内所作出的任何修改,等同替换或改进,均包含在本实用新型的保护范围之内。
