英文摘要	The utility model relates to a pure two force rod three degree of freedom paralleling mechanism which is suitable for the occasions of three degree of freedom operation, composed of a fixed platform, three groups of driving units of leading screws and nuts, six transmission rods, spherical hinges, hooke hinges and a motion platform, wherein, the three groups of driving units of leading screws and nuts, which are driven by a servo motor are vertically installed on the fixed platform. Sliders are fixedly connected with leading screws and nuts. Each unit group of leading screws and nuts is provided with two transmission rods. One end of the transmission rods is connected with the sliders through the hook hinges or the spherical hinges. The other end of the transmission rods is connected with the motion platform through the spherical hinges with common points. The utility model has the advantages of high rigidity, a good stressed characteristic and high transmission efficiency.
