Six-degree-of-freedom control rod based on flexible hinges

The invention provides a six-degree-of-freedom control rod based on flexible hinges. The six-degree-of-freedom control rod comprises an upper top cover, a central body, a lower bottom cover and a basewhich are sequentially connected through fasteners, the central body comprises an outer shell and a center operating rod, flexible hinge components are symmetrically arranged on two ends of the center operating rod, the flexible hinge components sequentially comprise outer hinges, center hinges and inner hinges along the length direction of the center operating rod, and the ends of the center operating rod are connected with the inner hinges. According to the control rod, six-degree-of-freedom control input of translational motion and rotation around an X axis, a Y axis and a Z axis is provided, so that control accuracy is high, response is rapid, and operation is visual, simple and convenient. 本发明提供了种基于柔性铰链的六自由度控制杆，包括通过卡扣依次连接的上顶盖、中心体、下底盖和底座，中心体包括外壳体和中心操作杆，中心操作杆的两端对称地设置有柔性铰链组件，沿所述中心操作杆的长度方向柔性铰链组件依次包括外铰链、中心铰链和内铰链；
