In the design process it analyzes this type construction and the problem that may appear in the working bining to synthesize to analyze its influence. Also this thesis rises the improve program about the function factor. Besides, the paper makes the notes about the axial force balance and the path force balance. In the structural process, the paper choose the reasonable structure, optimize the structure parameters and check the strength of the ponents to guarantee a good performance and reliability.
