Abstract

本实用新型公开了一种外五角螺丝,它包括头部(1)和杆部(2),头部(1)与杆部(2)连为一体,所述头部(1)的外侧设有外五角(3),与本实用新型配套的外五角扳手拧动螺丝时,头部(1)上外五角(3)至少有四个角受力;从而解决了工具带动头部(1)转动时易打滑的问题。本实用新型属于螺丝技术领域。

Description

外五角螺丝 
技术领域
本实用新型属于螺丝技术领域,尤其是涉及一种外五角螺丝。 
背景技术
现有技术中的螺丝一般包括头部和杆部,头部与杆部连为一体,头部外设有外六角,特别对于需要频繁拧入或者拧出螺丝的场合,上述结构的螺丝存在以下技术缺陷:绝大部分外六角螺丝的拧入与拧出可以形象的理解为两板夹住外六角螺丝的对称两边,然后通过两夹板的同时转动带动螺丝转动。该方式对外六角螺丝上的施力只作用在外六角螺丝的其中两个角上,在施力较大的情况下,工具和螺丝之间容易打滑,螺丝易被拧坏。 
实用新型内容
本实用新型所要解决的技术问题是:提供一种和工具一起转动时不易打滑的外五角螺丝。 
本实用新型所采取的技术方案是:一种外五角螺丝,包括头部和杆部,头部与杆部连为一体,所述头部的外侧设有外五角,杆部下端部分设有螺纹。 
本实用新型的有益效果是:头部同时设置有外五角,拧入或者拧出螺丝时可以使用与其配套的外五角扳手工具,使用方便;与本实用新型配套的外五角扳手拧动螺丝时,头部上外五角至少有四个角受力,从而解决了工具和螺丝之间易打滑的问题。 
附图说明
图1为本实用新型的总体结构示意图。 
图2为图1的俯视图。 
图中,1.头部,2.杆部,3.外五角,4.螺纹。 
具体实施方式
以下为本实用新型较佳实施例,但并不因此而限定本实用新型的保护范围。 
参照图1、图2所示,本实用新型外五角螺丝的一种实施例,它包括头部1和杆部2,头部1与杆部2连为一体,所述头部1的外侧设有外五角3,所述的杆部2下端部分设有螺纹4。所述的外五角3也就是头部1外圆周呈五边形。头部1的外五角3与外五角扳手相配。实用时可以用外五角扳手带动螺丝转动,由于本实用新型头部1外圆周呈五边形,不同于六边形,因此不存在对称边。与本实用新型配套的外五角扳手拧动螺丝时,头部1 上外五角3至少有四个角受力。从而解决了工具带动螺丝转动时螺丝易打滑的问题。
