Description

紧定螺钉
技术领域
本发明涉及一种紧定螺钉。
背景技术
涂布机收卷轴套装有用于夹紧薄膜卷卷芯的夹头，涂布时，夹头通过紧定螺钉固定在收卷轴上，每次上下卷都要寻找工具松开或紧定紧定螺钉，比较麻烦。
发明内容
本发明要解决的技术问题是：克服现有技术中之不足，提供一种紧定螺钉，手动该紧定螺钉即可将夹头从收卷轴上松开或固定。
本发明解决其技术问题所采用的技术方案是：一种紧定螺钉，包括螺杆，螺杆一端具有用于扳动螺杆的头部，所述头部开设有凹槽，凹槽一端固定有柱销，凹槽内容纳有柱状手柄，柱状手柄一端通过柱销和头部铰接，柱状手柄另一端伸出凹槽外。
本发明的有益效果是：扳动本发明不需要采用工具。使用时，将柱状手柄扳出凹槽，再通过柱状手柄扳动紧定螺钉，即可将夹头从收卷轴上松开或固定。
附图说明
下面结合附图和实施方式对本发明进一步说明。
图1是本发明的结构示意图。
图中：1.柱状手柄；2.凹槽；3.柱销。
具体实施方式
现在结合附图对本发明作进一步的说明。这些附图均为简化的示意图，仅以示意方式说明本发明的基本结构，因此其仅显示与本发明有关的构成。
如图1所示的一种紧定螺钉，包括螺杆，螺杆一端具有用于扳动螺杆的头部，所述头部开设有凹槽2，凹槽2一端固定有柱销3，凹槽2内容纳有柱状手柄1，柱状手柄1一端通过柱销3和头部铰接，柱状手柄1另一端伸出凹槽外。
上述实施方式只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并加以实施，并不能以此限制本发明的保护范围，凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围内。
