Abstract

一种伸缩杆连接装置,包括伸缩杆和扩展头,其中扩展头一端为带有插芯的圆型插头,插芯为呈等边三角形排列的三个凸条,圆型插头具有侧壁;扩展插头的另一端连接杆体;伸缩杆的两端是带插孔的圆型插座,分别与两个扩展头的原型插头插接。该装置使用方便,可根据需要更换扩展头,并且可自由安装拆卸。

Description

一种伸缩杆连接装置
技术领域
本实用新型涉及一种伸缩杆的连接装置。 
背景技术
目前现有技术中广泛采用伸缩杆来提供长度的可调节,然而伸缩杆与其它杆体的连接通常采用焊接或一体的方式,一旦固定不能更换,并且安装拆卸比较麻烦。 
发明内容
本实用新型的目的是提供一种克服上述问题的伸缩杆连接装置。 
本实用新型的技术解决方案是:包括伸缩杆和扩展头,其中扩展头一端为带有插芯的圆型插头,插芯为呈等边三角形排列的三个凸条,圆型插头具有侧壁;扩展插头的另一端连接杆体;伸缩杆的中部为可调节长度的杆体,伸缩杆的至少一端具有带插孔的圆型插座,插孔为与扩展头的插芯尺寸相适配的孔,以使得伸缩杆的该圆型插座与扩展头的该圆型插头插接。 
本实用新型的优点是:该装置使用方便,可根据需要更换扩展头,并且可自由安装拆卸。 
附图说明
下面结合附图和实施例对本实用新型进一步说明。
