Abstract

本实用新型涉及磁性可控螺丝批,属日用工具。本实用新型的实质在于在螺丝批的螺丝杆上设有绝缘线圈,所述绝缘线圈与开关和直流电源串联连接构成闭合回路。本实用新型利用通电绝缘线圈使螺丝批带有磁性,并通过开关控制电流的通断来实现磁性的可控。

Description

磁性可控螺丝批
技术领域
本实用新型涉及日用工具,具体来说涉及磁性可控螺丝批。
背景技术
在使用螺丝批时,为防止螺钉丢失,需要有磁性的螺丝批,上紧螺钉或取下螺钉时,将螺钉吸在螺丝杆的顶部,方便于操作。现有技术中有人利用小磁铁来磁化螺丝批以达到保存螺丝批磁性的目的,但这种磁性可控性不强。
发明内容
本实用新型的目的是提供一种在使用时具有较强磁性,并且磁性可控的磁性可控螺丝批。
本实用新型的技术解决方案是磁性可控螺丝批的螺丝杆上设有绝缘线圈,所述绝缘线圈与设在螺丝杆手柄上的开关和直流电源串联连接构成闭合回路。
以上所述的绝缘线圈可以是圈数可调的绝缘线圈。
本实用新型的优点是利用通电绝缘线圈使螺丝批带有磁性,并通过开关控制电流的通断来实现磁性的可控。
附图说明
图1是本实用新型的构造示意图。
具体实施方式
如图1所示,本实用新型包括螺丝批1,在螺丝批1的螺丝杆2上套装有绝缘线圈3,绝缘线圈3可制作成圈数可调的。在螺丝批1的手柄4上安装有电源开关5和五号电池6。绝缘线圈3与电源开关5和五号电池6串联连接构成闭合回路。绝缘线圈3和五号电池可以安装在螺丝批1的手柄4的内部,这样比较美观,使用起来更方便。使用螺丝批1时,如需要使螺丝批具有磁性,可将电源开关5打开,接通五号电池6,将绝缘线圈3通电,使螺丝批1产生磁性。不需要螺丝批1具有磁性时,只需将电源开关5关闭。

Claims (2)

1.磁性可控螺丝批,包括螺丝批,其特征在于在螺丝批的螺丝杆上设有绝缘线圈,所述绝缘线圈与设在螺丝批手柄上的开关和直流电源串联连接构成闭合回路。
2.如权利要求1所述的磁性可控螺丝批,其特征在于所述绝缘线圈为圈数可调的绝缘线圈。
