图中，拖把杆1、拖布支架2、连接部3、转向复位组件5、拖布转向盘4、凸轮51、复位组件52、导向弧面511、限位平面512、复位弹簧521、凸轮压块522、限位环523、定位槽524、旋转定位块513、配合槽513a、旋转固定件41、十字槽411、导向块412、第一固定轴31、旋转轴32、第二固定轴33。
具体实施方式
下面通过实施例，并结合附图，对本实用新型的技术方案作进一步具体的说明。
如图1所示，一种万向拖把，包括拖把杆1、拖布支架2，所述的拖把杆1与拖布支架2之间设有连接部3，所述的拖把杆1与连接部3铰接，所述的连接部3与拖布支架2之间周向转动连接，所述的连接部3与拖布支架2之间设有转向复位组件5，且当拖布支架2受周向转动方向的外力时，拖布支架2可以连接部3轴线为中心转动，当拖布支架2解除周向转动方向外力时所述的拖布支架2可在转向复位组件5的作用下复位。本实施例在拖布支架2受周向转动方向的外力时可以自行进行周向转动，无需用户自行调整。不同于现有技术中的前后或左右转动，拖布支架2周向转动，可以保证清洁时无死角。在障碍消失后，转向复位组件5的作用可以使拖布支架2自行复位，无需用户再进行调整。方便使用的同时，还提高了用户的使用感。
进一步地，为了保证本实施例在使用过程中的稳定性，所述的连接部3与拖布支架之间还设有拖布转向盘4，所述的拖布转 向盘4和拖布支架2周向转动连接，所述的拖把杆1和拖布支架2通过拖布转向盘4连接。
如图3所示，所述的转向复位组件5包括凸轮51和复位组件52，所述的凸轮51和拖布转向盘4固定连接，所述的凸轮51上包括导向弧面511和限位平面512，所述的复位组件52具有始终顶压于凸轮51外表面的趋势，所述的复位组件52在不受外力时始终顶压于凸轮51的限位平面上。因此，由于凸轮51和拖布转向盘4固定连接，保证转向复位组件5不会随意转动，复位组件52在不受外力时始终顶压于凸轮51的限位平面上，防止了拖布支架2影响用户的清洁效率。
所述的导向弧面511和限位平面512数量均不小于2个，所述的2个复位组件52对称设置在拖布支架2轴心线两侧，所述的复位组件52包括若干复位弹簧521，所述的复位弹簧521一端与凸轮51相接。本实施例使用复位弹簧保证扫把可以稳定的转动和复位，不会因为受到外力，拖布支架2转动角度过大达不到用户清洁目的。
如图3所示，所述的复位组件52还包括凸轮压块522和限位环523，所述的凸轮压块522设置在复位弹簧521靠近凸轮51的一端，所述的限位环523与复位弹簧521相配合，所述的限位环523与凸轮压块522固定连接，所述的限位环523的长度短于复位弹簧521的长度。本实施例通过设置限位环523对复位弹簧521进行导向作用。
为了延长产品的使用寿命，也为了降低弹簧的损耗，所述的复位组件52还包括定位槽524，所述的定位槽524设置在复位弹簧521远离凸轮51的一端，所述的定位槽524与限位环523滑动连接，所述的定位槽524在与限位环523相接的一端还设置让位槽。
本领域的技术人员应当理解，为了拖布支架2在转动时受力 均衡，所述的复位组件52包括不少于两根复位弹簧521，所述的不少于两根的复位弹簧521均与1个凸轮压块522相连，所述的凸轮压块522与复位弹簧521相连的一侧设置若干弹簧定位块。
为了更好地实现复位组件52在不受外力时始终顶压于凸轮51的限位平面上，所述的凸轮压块522包括对称设置的2个限位弧面511和2个导向平面512，所述的2个导向平面512之间通过限位弧面511相连，所诉的2个限位弧面511之间的距离大于2个导向平面512之间的距离。
所述的拖布支架2沿复位弹簧521轴向的截面为梯形，所述的定位槽524远离凸轮51的一端凸起于拖布支架2上表面。由此，本实施例进一步减小了拖把支架的体积，更方便用户对缝隙等进行清洁。
凸轮51与拖布转向盘4相接的一面的轴心处设置旋转定位块513，所述的旋转定位块513设置与连接部3未和拖把杆1相连的一端相配合的配合槽513a。所述的旋转定位块513和配合槽513a使得拖把杆1进行转动，用户因此可以更方便地根据使用场景调整拖把。
为了加强本实施例的稳定性，所述的拖布转向盘4在轴心处设置固定连接部3的旋转固定件41，所述的旋转固定件41设置十字槽411，所述的十字槽411与配合槽513a卡接，所述的旋转固定件41还包括导向块412，所述的导向块412设置在拖布转向盘4与拖把杆1相接的一侧。
优选地，所述的连接部3包括第一固定轴31、旋转轴32和第二固定轴33，所述的旋转轴32设置在拖把杆1与拖布支架2相连一端的凹槽内，所述的旋转轴32穿设第一固定轴31，旋转轴32远离拖把杆1的一端穿设第二固定轴33，所述的第一固定轴31和第二固定轴33相垂直。
本实施例的工作原理是：拖把杆1通过连接部3的旋转轴32 和第二固定轴33与拖布支架2和转向复位组件5连接。所述的复位组件52在不受外力时始终顶压于凸轮51的限位平面上，拖布支架2可以稳定的进行清洁，当拖布支架2受周向转动方向的外力时，拖布支架2以连接部3轴线为中心转动，复位弹簧521发生形变，凸轮压块522随限位环523相对凸轮51转动，即复位组件52从限位平面512向导向弧面511移动，保证拖布支架2的相对稳定。当外力消失时，复位弹簧521产生的作用力使得复位组件52向限位平面512复位，从而带动拖布支架2复位。
本文中所描述的具体实施例仅仅是对本实用新型精神作举例说明。本实用新型所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本实用新型的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了拖把杆1、拖布支架2、连接部3、转向复位组件5、拖布转向盘4、凸轮51、复位组件52、导向弧面511、限位平面512、复位弹簧521、凸轮压块522、限位环523、定位槽524、旋转定位块513、配合槽513a、旋转固定件41、十字槽411、导向块412、第一固定轴31、旋转轴32、第二固定轴33等术语，但并不排除使用其它术语的可能性。使用这些术语仅仅是为了更方便地描述和解释本实用新型的本质，把它们解释成任何一种附加的限制都是与本实用新型精神相违背的。
