[0031] After the device is installed, the staff manually pulls the limit block 27 outward to separate the limit block 27 from the connecting rod 22, and then uses the fastening bolts to pass through the connecting base 25 and fix the connecting base 25 to the ground. When the device shakes due to strong winds or other factors, the rotating rod 21 will squeeze the shock-absorbing spring 23 and the damping rod 24 inside the connecting rod 22, thereby keeping the device stable. The above is the working process of the device. The above is the working process of the device.
