一种可控制下压旋拧电动螺丝刀
本技术涉及螺丝刀领域,具体为一种可控制下压旋拧电动螺丝刀。
技术介绍
电动螺丝刀简称电批,是一种装有调节和限制转矩机构的电动工具,用于拧紧和旋松螺钉。电动螺丝刀比普通螺丝刀具有操作简便、高效等优势,是生产企业必备的电动工具之一,也是在日常生活中使用频率较高的工具。但目前市场上的电动螺丝刀存在这样的问题,当螺钉拧到位后,螺丝刀会继续转动,容易造成螺钉头损坏。
技术实现思路
为实现上述目的,本技术提供如下技术方案:一种可控制下压旋拧电动螺丝刀,包括螺丝刀、机壳和手柄,所述手柄与机壳相连接,所述螺丝刀通过紧定螺钉连接有传动轴,所述传动轴连接有制动装置,所述制动装置包括外套和离合器,所述离合器安装在外套上,所述离合器上安装有支轴,所述支轴上安装有第一弹簧,所述第一弹簧连接有第一钢球,所述支轴连接有下打滑离合,且下打滑离合通过隔片连接有上打滑离合,所述隔片上安装有第二钢球,所述上打滑离合连接有心轴,所述心轴的两侧均安装有弹簧组件,且心轴连接有软轴,所述弹簧组件通过垫圈连接有螺母,所述螺母连接有带动轴,所述软轴的两侧均安装有滑动圈。作为本技术一种优选的技 ...
