[0026] In a preferred embodiment, there are three groups of anti-dancing structures 2, and the three groups of anti-dancing structures 2 are evenly distributed on the outer wall of the mounting end 1. The outer wall of the rotating handle 202 away from the wind speed detector 201 is sleeved on the outer wall of the rotating rod 9. Both ends of the connecting rod 206 are installed with connecting handles 205, and the connecting handles 205 roll on the outer wall of the rolling ball 204.
[0027] By utilizing the above structure, the wind speed can be detected by the wind speed detector 201, so that the wind speed detector 201 can generate a signal when the wind speed exceeds the limit value, and the rotating handle 202 can be rotated through the rotating rod 9, and the connecting handle 205 can be rotated on the outer wall of the rolling ball 204, so that the connecting rod 206 can drive the fixed end 4 to move through the connecting handle 205 on the other side, thereby achieving the state of tensioning the transmission line.
