Please refer to fig. 1, the bottom end of the clamping plate 3 is provided with a threaded hole matched with the screw rod 7, and the clamping plate 3 is rotatably connected with the screw rod 7 through the threaded hole, so that the screw rod 7 can drive the clamping plate 3 to clamp the lightning rod 1 through rotation, thereby realizing the convenience of mounting the lightning rod 1.

Please refer to fig. 1, the position of the position-limiting post 4 matches the position of the threaded hole 2, and the outer wall of the position-limiting post 4 fits the inner wall of the threaded hole 2, so that the clamping plate 3 keeps the lightning rod 1 from being limited when clamping the lightning rod 1, and the problem that the lightning rod 1 is separated from the needle base 5 in wind and rain weather is avoided.

Please refer to fig. 1, the top end of the needle base 5 is provided with a sliding groove matched with the clamping plate 3, and the inner wall of the sliding groove is matched with the outer wall of the clamping plate 3, so that the screw rod 7 can effectively drive the two clamping plates 3 to approach to the middle when rotating, thereby realizing the clamping function of the clamping plates 3.

Referring to fig. 4, the dispersible tablet 12 is engaged with the engaging hole 13 through the spring 14 and the engaging head 15, and the outer wall of the engaging head 15 is engaged with the inner wall of the engaging hole 13, so that the dispersible tablet 12 is easily connected to the main body of the dispersing base 10, thereby improving the convenience of connection and the installation efficiency.

Please refer to fig. 1, one side of the screw rod 7 is a positive thread, and the other side of the screw rod 7 is a negative thread opposite to the positive thread, so that the screw rod 7 can effectively drive the two clamping plates 3 to move closer to the middle when rotating, thereby realizing the function of clamping the lightning rod 1 by the clamping plates 3.

The working principle is as follows: when the lightning arrester is installed, firstly, the lightning rod is erected between two clamping plates 3 at the top end of a needle base 5, a threaded hole 2 in the lightning rod is aligned with a limiting post 4, then a rotating bolt 8 is screwed by a tool to rotate, when the rotating bolt 8 rotates, a screw rod 7 is driven to rotate, as one side of the screw rod 7 is a positive thread and the other side is a reverse thread opposite to the positive thread, and the bottom ends of the two clamping plates 3 are provided with screw rod holes matched with the screw rod 7, the screw rod 7 drives the two clamping plates 3 to approach towards the middle when rotating, the limiting post 4 is inserted into the threaded hole 2 until being clamped and fixed in the approaching process, then, a spring 14 is compressed by pressing a clamping head 15 to be accommodated into a dispersible tablet 12, then the dispersible tablet 12 is sequentially inserted into a tablet groove 11, when the dispersible tablet 12 is inserted into the clamping head 15 and moves to a clamping hole 13, the compressed force of the spring 14 starts to drive the clamping head 15 to reset, when the spring 14 drives the chuck 15 to reset and clamp into the clamping hole 13, the dispersion seat 10 is buried underground, and then in thunderstorm weather, because the lightning rod needle head is sharp, the tip of the conductor always gathers the most electric charges in electrostatic induction, and forms a capacitor with an electrified cloud layer, when the electric charges on the cloud layer are more, the air between the lightning rod and the cloud layer is easily punctured into the conductor, the current formed by lightning is transmitted to the dispersion seat 10 through the metal strip 9, the dispersion seat 10 transmits the current to the ground, and because the contact area of the dispersion seat 10 and the ground is effective, the contact area of the dispersion seat 12 and the ground is increased, and therefore the better current guiding effect is achieved.
