[0039] When using, refer to Figure 4 , install the support base 221 on the wind turbine blade 12, and then place the mounting plate on the support base 221, so that when lightning occurs, the lightning rod 3 223 can assist in attracting lightning and effectively protect the wind turbine blade 12 from damage by lightning. The lightning rod 3 223 can assist in attracting lightning and the three lightning rods 214 and the lightning rod 1 213 can coordinate to attract lightning, thereby improving the lightning attracting effect and further increasing the lightning protection effect.

Then, the toggle seat 332 is toggled to realize the clockwise / counterclockwise deflection of the rotating seat 311, and then it is toggled downward so that the two magnets 334 are habitually adsorbed and connected, thereby realizing the restriction and fixation of the rotating seat 311 and preventing the rotating seat 311 from deflecting autonomously.

When the fixing member 321 is inserted into the fixing groove 325 and the toggle seat 332 is toggled downward, the connecting rod 341 drives the pushing member 342 to move downward, so that the reinforcement seat is inserted into the reinforcement groove 346.
