实施例3
如图7及图8所示，一种多圆管夹持装置，包括用于安装管状器材的夹持座1，及至少一个用于锁紧管状器材的锁紧组件2，所述夹持座1内设有至少一个安装凹槽11，每一所述安装凹槽11中设置一个锁紧组件2，所述安装凹槽11的底部设有至少两个管孔12，各所述管孔12设有开口13，所述开口13与安装凹槽11连通；所述锁紧组件2包括压紧板21、锁紧旋钮22及复位弹簧23，所述压紧板21设于安装凹槽11中，所述压紧板21上设有至少两个抵块211，所述抵块211位于开口13内，所述锁紧旋钮22穿过压紧板21与安装凹槽11连接。
如图8所示，作为优选的，夹持座1为板状夹持座，板状夹持座相对的两端面分别设有一个安装凹槽11，各安装凹槽11的底部设有两个管孔12。需要说明的是，各压紧板21上设置抵块211的数量与各安装凹槽11底部设置的管孔12数量相互对应的，本实施例中，每一压紧板21上设有两个抵块211，两抵块211分别位于压紧板21的两侧。安装凹槽11用于安装锁紧组件2，各安装凹槽11两侧设有两管孔12，各管孔12内可套设延长管，通过锁紧组件2对管孔12内的延长管进行锁紧固定。
如图7及图8所示，本实施例中，复位弹簧23套设于锁紧旋钮22，当需要锁紧时，只需顺时针旋转锁紧旋钮22，从而带动压紧板21往下挤压，使压紧板21上的抵块211与延长管相互抵接，延长管被牢靠固定；当需要拆卸延长管时，只需逆时针旋转锁紧旋钮22，在复位弹簧23的弹力作用下，压紧块21向上移动，抵块211不再与延长管抵接，此时，可顺利拔出延长管完成拆卸，整个锁紧拆卸过程简单方便。需要说明的是，为增大延长管与抵块211之间的锁紧力，抵块211上设有与延长管弧度相互适配的凹弧。另外，需要说明的是，复位弹簧23还可设于加装的固定螺杆上，当逆时针旋转锁紧旋钮22时，也能 使压紧板21实现复位的效果，本实施例仅为较佳实施例而已。
如图1所示，更进一步的，Z字型夹持座中部设有至少一个镂空的通槽17。镂空的通槽17设计，可大大减少板状夹持座的体积，使得整体重量更加轻盈，方便携带。
采用上述各个技术方案，本实用新型在夹持座上设有安装凹槽，与安装凹槽连通的管孔，延长管可分别套设于管孔，安装凹槽上设置的锁紧组件，可通过调节锁紧旋钮促使压紧板上的抵块与延长管相抵接，从而同时锁紧固定两根延长管，松脱时，只需反向调节锁紧旋钮，操作简单，锁紧牢靠；整体结构简单、体积小巧，使用方便。
以上仅为本实用新型的较佳实施例而已，并不用于限制本实用新型，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。
