The arrangement of the linear sliding table module 3 is adopted, so that the movement precision and stability of the truss are improved. When meetting the condition of defense strong wind weather, drive truss group 2 through sharp slip table module 3, realize that second truss 22 and third truss 23 are close to first truss 21 direction for the distance between each other is shortened to the cable on the different trusses, reaches the effect that reduces transmission tower amplitude of rocking. The same, when the strong wind weather subsides, drive truss group 2 through sharp slip table module 3, realize that second truss 22 and third truss 23 move to keeping away from first truss 21 direction for the cable on the different trusses pulls open certain distance, resumes normal shape.
