The outside of the connecting block 3 is slidably connected to the inside of the connecting groove 9. The two groups of connecting blocks 3 can clamp the bottom of the transmission and transformation tower to make it more stable. A connecting groove 9 is provided on the left part of the connecting plate 1. The connecting groove 9 can be clamped to the outside of another group of connecting blocks 3 so that it can be fixedly connected to increase the cross-sectional area of ​​the ground and increase the lateral force.
