[0025] Reference Figure 1 , Figure 2 and Figure 3 A lightning arrester of the utility model comprises a mounting seat 1, a support frame 2 is fixedly mounted on the upper surface of the mounting seat 1, a support rod 3 is rotatably connected to the inner wall of the support frame 2 through a connecting shaft, a lightning rod 4 is fixedly mounted on one end of the support rod 3, a groove is provided at the end of the support rod 3 away from the lightning rod 4, a rotating ring 5 is rotatably connected to the inner wall of the groove, a pulling steel rope 6 is fixedly mounted on the surface of the rotating ring 5, a winding component for winding the pulling steel rope 6 is provided on the side of the support frame 2 away from the rotating ring 5, and a limiting component for fixing the support rod 3 is provided at the bottom of the support frame.

[0026] In some specific embodiments of the utility model, the winding assembly is composed of a storage box 7, a protection box 8, a guide wheel 9, a winding roller 10 and a motor 11. The storage box 7 is fixedly mounted on the left side of the support frame 2, and the winding roller 10 is rotatably mounted on the inner wall of the storage box 7. A through hole for the pulling steel rope 6 to pass through is opened at the lower end of the storage box 7, a through groove is opened on the left side of the support frame 2, and the guide wheel 9 is rotatably mounted on the inner wall of the through groove. The end of the pulling steel rope 6 away from the support rod 3 passes through the through groove and the through hole respectively, and is wound around the surface of the winding roller 10. The protection box 8 is fixedly mounted on the front of the storage box 7, and the motor 11 is fixedly mounted on the inner wall of the protection box 8, and the output end of the motor 11 extends to the interior of the storage box 7 and is fixedly connected to the front of the winding roller 10.
