一种换头式螺丝刀
技术领域
      本实用新型涉及一种换头式螺丝刀。 
背景技术
    现在的螺丝刀头部只有一种样式，不能用来拧规格不同的螺丝，要备用多把螺丝刀，成本较高，携带不方便。 
发明内容
     本实用新型所要解决的技术问题在于提供一种可换多种螺丝刀头的螺丝刀。本实用新型是通过以下技术方案来实现的： 
一种换头式螺丝刀，包括螺丝刀柄、螺丝刀杆、螺丝刀头和磁性块；所述螺丝刀柄为中空型，头部装有盖子；所述螺丝刀杆为正四边形；所述螺丝刀头可拆卸；所述磁性块安装在螺丝刀杆的前端。
作为优选，所述的螺丝刀头一端为正四边形，与螺丝刀杆为间隙配合。 
     本实用新型的有益效果是：通过安装在螺丝刀杆前端的磁性块吸住螺丝刀头，螺丝刀杆和螺丝刀头都是正四边形，使用时不用出现打转现象，更换螺丝刀头时，旋开螺丝刀柄上有的盖子，从中拿出要更换的螺丝刀头；这种螺丝刀结构简单，使用方便，推广容易。 
附图说明
      为了易于说明，本实用新型由下述具体实施例及附图作以详细描述。
      图1为本实用新型换头式螺丝刀的示意图。
