Abstract

本实用新型涉及一种螺丝刀。它是由柱状杆体和空心把柄构成,柱状杆体的中间部位呈等边四棱体,柱状杆体的一边端头呈“十”字型的螺丝刀刃口状,另一边端部呈锥形螺纹状。空心把柄的插入口呈能够与柱状杆体四棱体配合的内等边四棱孔。本实用新型的有益效果是:使拧螺丝钉的人们能够安全、准确、方便的将螺丝钉拧进预先确定的位置。

Description

一种螺丝刀
所属技术领域
本实用新型涉及一种螺丝刀。
背景技术
众所周知,当人们要向木质材料中拧进螺丝钉时,常常先用一个大钉子和一把锤子在需拧螺丝钉的地方琢一个微洞。人们琢一个微洞固然有它的道理,但是,这样的琢洞方法也存有一些不便:其一,人们干的是拧螺丝钉的工作,还要额外的携带一些钉子和锤子。其二,用锤子敲击钉子一定会出现令人讨厌的噪声。可见,发明一种既有拧螺丝功能、又没有琢洞噪声的螺丝刀是有意义的。
发明内容
本实用新型的目的在于提供一种没有琢洞噪声的螺丝刀。
一种螺丝刀,它是由柱状杆体和空心把柄构成;柱状杆体的中间部位呈等边四棱体,柱状杆体的一边端头呈“十”字型螺丝刀刃口状,另一边端部呈锥形螺纹状;空心把柄的插入口呈能够与柱状杆体四棱体配合的内等边四棱孔。
本实用新型的有益效果是:使拧螺丝钉的人们能够安全、准确、方便的将螺丝钉拧进预先确定的位置。
附图说明
下面结合附图和实施例对本实用新型做进一步说明。
附图1是本实用新型结构示意图。
其中,1、柱状杆体,2、空心把柄。
具体实施方式
当人们欲要在木质材料的某点拧进螺丝钉时,可先将柱状杆体(1)的呈“十”字型螺丝刀刃口端体插入空心把柄(2)内,再手持空心把柄(2)将柱状杆体(1)的锥形螺纹拧进螺丝钉的欲拧进点,待拧进一定的深度之后,再将柱状杆体(1)的锥形螺纹反向拧出。然后,将螺丝钉旋入拧进点,并用柱状杆体(1)的“十”字型螺丝刀刃口端将该螺丝钉进一步的拧进、拧紧。
