所述上管和中管之间、中管和下管之间均通过止转组件固定连接；所述止转组件包括止转座和止转头。
所述的一种锁紧式拖把杆，其特征在于所述上管和下管与中管连接一端内侧的侧壁均设有内螺纹，中管两端外侧的侧壁均设有与内螺纹相匹配的外螺纹。
所述的一种锁紧式拖把杆，其特征在于所述上管和下管与中管连接一端的内部均卡接有止转座，所述止转座分别与上管和下管的侧壁打点固定。
所述的一种锁紧式拖把杆，其特征在于所述中管的两端均插接有止转头，所述止转头与中管的侧壁打点固定。
所述的一种锁紧式拖把杆，其特征在于所述止转座为环状结构，环状结构内侧侧壁上开设有止转座卡齿。
所述的一种锁紧式拖把杆，其特征在于所述止转头包括插入中管中的插入端，限位台阶段，设置在限位台阶段上的止转段，所述止转段包括两个对称放置的弧形止转片，所述弧形止转片的外部设有与止转座上止转座卡齿相匹配的止转头卡齿。
所述的一种锁紧式拖把杆，其特征在于所述止转座卡齿和止转头卡齿均为单向齿。
所述的一种锁紧式拖把杆，其特征在于所述上管和中管之间、中管和下管之间连接处的外侧均设有护套。
通过采用上述技术，与现有技术相比，本实用新型的有益效果如下：
本实用新型上管和中管、中管和下管在通过内、外螺纹旋合连接时，通过设置的止转座和止转头之间的单向卡齿配合结构，限制止转座和止转头之间沿着内外螺纹旋合的反向转动，防止螺纹连接的上管和中管、中管和下管之间因为螺纹老化松动或者外力作用，产生滑动；且装置采用的分体装配结构能够减少包装材料、节约包装运输空间、安装简单方便。

具体实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合说明书附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
相反，本实用新型涵盖任何由权利要求定义的在本实用新型的精髓和范围上做的替代、修改、等效方法以及方案。进一步，为了使公众对本实用新型有更好的了解，在下文对本实用新型的细节描述中，详尽描述了一些特定的细节部分。对本领域技术人员来说没有这些细节部分的描述也可以完全理解本实用新型。
请参阅图1-7，一种锁紧式拖把杆，包括上管1、中管2和下管3，所述上管1的外端固定安装有手柄4,手柄4的外端固定安装有转头5， 所述下管3的外端固定安装有万能接头6；所述上管1和中管2之间、中管2和下管3之间均通过止转组件固定连接；所述止转组件包括止转座7和止转头8。
所述上管1和下管3与中管2连接一端内侧的侧壁均设有内螺纹9，中管2两端外侧的侧壁均设有与内螺纹9相匹配的外螺纹10；上管1和中管2之间、中管2和下管3之间连接处的外侧均设有护套11。
所述上管1和下管3与中管2连接一端的内部均卡接有止转座7，所述止转座7分别与上管1和下管3的侧壁打点固定；所述中管2的两端均插接有止转头8，所述止转头8与中管2的侧壁打点固定。
其中，止转座7为环状结构，环状结构内侧侧壁上开设有止转座卡齿；止转头8包括插入中管2中的插入端81，限位台阶段82，设置在限位台阶段82上的止转段83，所述止转段83包括两个对称放置的弧形止转片831，所述弧形止转片831的外部设有与止转座7上止转座卡齿相匹配的止转头卡齿；止转座卡齿和止转头卡齿均为单向齿。
本实用新型在装配时，采取的主要技术方案有：将止转座7分别卡入上管1和下管3与中管2连接端的内部，并通过在上管1和下管3对应位置的外侧壁打点将止转座7卡接固定，将护套11套设在上管1和下管3与中管2连接端的外侧，再将止转头8插入中管2的两端并打点固定；固定好止转头8的中管2的两端分别插入上管1和下管3对应端，旋合内螺纹9和外螺纹10，此时，弧形止转片831上的止转头卡齿与止转座7上的止转座卡齿单向卡合，使得止转座7和止转头8无法沿着内外螺纹旋合的反方向旋转，从而将上管1和中管2、下管3和中管2锁紧。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
