为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图及实施例对本发明作进一步详细说明。应当理解，此处所描述的具体实施 例仅用以解释本发明，并不用于限定本发明。
一种用于布料的可折叠划线装置，如图1-8所示，包括两根底座1、调节机构2、转动机构3、第一引导尺4和第二引导尺5，底座1呈长方体结构，两根底座1通过铰链铰接在一起，其中一根底座1的一端固定设置转角连接块6；展开时，另一根底座1的一端紧贴转角连接块6的一端面，此时，两根底座1相互垂直呈L形。调节机构2包括滑块21和转动块22，滑块21滑动设置在底座1上，转动块22水平转动设置在滑块21上，转动块22径向设置贯穿的且与第一引导尺4配合的第一引导孔23；调节机构2分设在两根底座1上，第一引导尺4包括尺本体和设置在尺本体端部向一侧延伸的连接部41，两根第一引导尺4的连接部41铰接在一起，并且两根第一引导尺4分别滑动设置在两根底座1上的第一引导孔23内；转动机构3设置在其中一根第一引导尺4上，第二引导尺5滑动设置在转动机构3上，并且利用手拧螺栓固定，第二引导尺5的一端设置划线部51，划线部51上设置用于插入划线笔的划线孔52。通过转动机构3使得第二引导尺5以转动机构为中心转动，实现圆弧的绘制。
在一实施例中，如图1-8所示，底座1的的上表面和一侧面沿其长度方向设置导槽11，滑块21呈L形，在其每边的内侧设置与导槽11配合的导块24，转动块22转动设置在滑块21的上表面，滑块21的侧表面设置螺孔，手拧螺栓设置在螺孔内，利用手拧螺栓将滑块21与底座1固定。
在一实施例中，如图1-8所示，转角连接块6的一侧设置磁块，利用磁块吸引和固定底座1的一端面。另外，底座1的底部设置与桌面吸引的电磁铁，对应的，桌面采用能够被磁铁吸附的材质制成。对于电磁铁的电源，能够通过充电宝等进行供电。将辅助划线装置放置在目标位置后，启动电磁铁，使得底座1牢固的吸附在桌面上，保证在划线时，底座1不发生移动。
在一实施例中，如图1-8所示，划线部51呈圆柱体，且向下延伸至与底座1的下表面齐平，划线孔52设置在划线部51的圆心处。使用时，划线笔插入划线孔内，作业员握住划线部51，以驱动划线笔移动。优选的， 划线部51的底部设置钢珠滚轮。通过钢珠滚轮使得划线部51与布料之间为滚动摩擦，使得划线笔移动更加顺滑。另外，由于划线部51的下表面与底座1齐平，因此，通过钢珠滚轮，会将划线部51略微抬起，使得划线部51向桌面施加一个相对的下压力，保证划线部51紧贴布料。
在一实施例中，如图1-8所示，转动机构3包括旋转底座31和旋转块32，旋转块32转动设置在旋转底座31上，旋转块32径向设置贯穿的且与第二引导尺5配合的第二引导孔33以及用于锁定第二引导尺5的螺孔，螺孔设置在旋转块32的上表面，手拧螺栓设置在螺孔内。将第二引导尺5拉出指定距离后，旋转手拧螺栓，使得其端部紧压在第二引导尺5上，实现第二引导尺5与转动机构3的固定。同时利用旋转块32与旋转底座31转动连接，使得划线笔能够绘制以旋转块32旋转中心为圆心，伸出的第二引导尺5的长度为半径的圆弧。
在一实施例中，如图1-8所示，旋转底座31向下延伸设置支撑部34，支撑部34的底部与底座1的下表面齐平，并且支撑部34的底部设置钢珠滚轮。
在一实施例中，如图1-8所示，旋转底座的一侧设置定位部35，定位部35的形状与划线部51配合；即，划线部51为圆柱体时，定位部35为凹设的圆弧面。当划线部51处于定位部35内时，该位置为基准位置。
在一实施例中，如图1-8所示，还包括定位针36，旋转底座31的下表面凹设导向孔，并且与旋转块32的旋转中心对应，导向孔底部设置磁铁，定位针36间隙配合设置在导向孔内，并且与磁铁吸附。当使用时，将定位针36拉下，确定圆弧的圆心；在不使用时，定位针36的尾部吸附在磁铁上，使得定位针36的下端远离布料，避免影响正常划线。
在一实施例中，如图1-8所示，还包括插销座37和插销38，插销座37设置在第一引导尺4的底部，插销38滑动设置在插销座37内，旋转底座31的一侧设置销孔，当两根第一引导尺4呈L形设置时，插销38插入销孔内将两根第一引导尺4固定。
在一实施例中，如图1-8所示，还包括定位块42，第一引导尺4上沿其侧边方向交替设置若干个定位孔43，定位块42紧配合设置在定位孔43内，并且定位块42突出于定位孔43。优选的，在定位孔一侧标注刻度，根据该刻度将定位块42插入对应的定位孔43内，限制第一引导尺4伸出距离。
本发明在使用时，如图1-8所示，将布料铺平在桌面上，将划线装置展开，并将其放置在目标位置，启动电磁铁将装置进行固定。当绘制X方向直线时，将划线部51置于定位部35内，并且通过手拧螺栓将第二引导尺5锁定，而后锁定Y方向上的滑块21，将定位块42插入对应长度位置的定位孔43，将划线笔插入划线孔52内，并且移动划线笔在布料上进行划线，同时带动第一引导尺4沿X方向移动，以实现X方向上的划线。当需要绘制圆弧时，同时锁定两侧的滑块21，同时松开旋转块32上的手拧螺栓，调整第二引导尺5伸出距离，即划线孔52至旋转块32旋转中心的距离为圆弧的半径；旋紧手拧螺栓。而后将划线笔塞入划线孔52，驱动划线笔在布料上移动，实现圆弧的绘制。
如图1-8所示，划线装置展开时，展开底座1，使得两底座呈L形。同时展开第一引导尺4，将插销38插入插销孔内，保证第一引导尺4呈L形；到达图1所示状态。当折叠时，拔出插销38后两第一引导尺4相向转动，并且将底座1对折，而后推动调节机构2移动至靠近转角连接块6，而后锁定调节机构2的手拧螺栓进行固定，到达图8所示状态。
以上仅为本发明的较佳实施例，并非用来限定本发明的实施范围；如果不脱离本发明的精神和范围，对本发明进行修改或者等同替换，均应涵盖在本发明权利要求的保护范围当中。
