一种扳手
技术领域
本实用新型涉及一种扳手。
背景技术
在太阳能光伏行业的单晶硅圆棒生长过程中,对生产设备单晶炉要拧加热器螺丝,由于螺丝是石墨做的,经过高温后会跟加热器底部连接在一起,通过普通扳手往往不能将螺丝拧下来,需要借助榔头大力敲击螺丝,甚至还会将工具拧弯或者拧断,非常困难。这样的问题在其它一些设备的紧固部位也经常存在。
实用新型内容
实用新型目的:针对上述问题,本实用新型的目的是提供一种使用方便而且有效可靠的扳手。
技术方案:一种扳手,包括手柄和拧头,所述拧头上开设有与紧固件拧固部位形状相匹配的槽。
有益效果:与现有技术相比,本实用新型的优点是在扳手的拧头上开设有与紧固件拧固部位形状相匹配的槽,使得紧固件的拧固部位能够落入槽中,多面同时、均匀受力,从而轻松将其拧下来,使用方便、有效。
附图说明
图1为本实用新型主视图;
图2为图1的A向视图。
具体实施方式
下面结合附图和具体实施例,进一步阐明本实用新型,应理解这些实施例仅用于说明本实用新型而不用于限制本实用新型的范围,在阅读了本实用新型之后,本领域技术人员对本实用新型的各种等价形式的修改均落于本申请所附权利要求所限定的范围。
如附图1、2所示,一种扳手,包括手柄1和拧头2,拧头2上开设有与紧固件拧固部位形状相匹配的槽3,槽3的截面形状可以是圆形、六边形等,与螺丝、螺母等紧固件的形状、大小一致。
