Description

持钉磁头改锥
技术领域
本发明涉及手工具，具体为持钉磁头改锥。
背景技术
电气产品的螺钉安装位置有两类：凸显的和凹陷的。凹陷位置的螺钉，装时不易认位；卸时不便抓取。人们先是将改锥头磁化，利用铁制螺钉的铁磁性，吸住螺钉来装卸。近年在此基础上，于改锥头上涂覆磁层，研制出磁头改锥，大大方便了凹陷位置螺钉的装卸；但是仍有不能吸持铜铝螺钉和吸持不正，改锥轴线与螺钉轴线不能同处一线的缺点。
发明内容
本发明解决现有磁头改锥不能吸持铜铝螺钉和对铁制螺钉吸持不正的问题，提供一种持钉磁头改锥。
本发明是采用如下技术方案实现的：持钉磁头改锥，包括磁头改锥本体，在磁头改锥本体上设置有持钉器，所述的持钉器由环套于磁头改锥本体锥杆上的导圈和粘固于导圈上且长度大于导圈长度的索套构成。所述的导圈和索套是用弹性材料制成的。
导圈靠切向弹力抱在磁头改锥本体锥杆上，可沿锥杆滑动，并能固定在锥杆的任意位置。索套粘在导圈上，可随导圈滑动。使用时，装螺钉：将导圈连同索套推向改锥头，并使索套适度超出改锥头端面。然后把欲装螺钉头撑开并***索套，还要使改锥头对准螺钉的一字槽或十字槽。因索套有弹性，不仅可以握持住螺钉头；而且可以使螺钉头轴线与改锥杆轴线同心，保证螺钉认位准确迅速。而后便可转动改锥把儿，将螺钉拧入钉孔。收回改锥，装钉完毕。因索套经导圈抱紧改锥杆，而且索套与改锥头的抱合段远大于索套对螺钉头的抱合长度，故螺钉头会顺利脱出索套；不会发生索套被拔离改锥杆的情况。卸螺钉：导圈连同索套静置改锥把跟儿不动。使改锥去卸螺钉。卸下后，靠改锥头磁力吸取。
持钉磁头改锥的有益效果是：对螺钉握持可靠，安装认位准确，卸后吸取方便，适于凹陷位置螺钉的装卸。
附图说明
图1为本发明的结构示意图；
图中：1－锥杆，2－导圈，3－索套。
具体实施方式
持钉磁头改锥，包括磁头改锥本体，在磁头改锥本体上设置有持钉器，所述的持钉器由环套于磁头改锥本体锥杆1上的导圈2和粘固于导圈2上且长度大于导圈长度的索套3构成。具体制造时，导圈2顺一字头改锥扁平面穿在改锥杆1上；或者径自穿在十字头改锥杆1上。然后把索套3粘在已经装于改锥杆1上的导圈2上。导圈2用高弹塑料制造；高10mm；装前内径小于锥杆（1）直径；皮厚2mm；有一轴向缝。索套3用高弹乳胶制造。长度等于导圈2高与磁头改锥本体锥头长、螺钉头长之和。装前内径小于锥杆1直径。皮厚1mm。
