[0046] When the output end of the electric telescopic rod 56 is extended, the clamping assembly 57 is pushed by the output end of the electric telescopic rod 56, and drives the guide column 54 to move to the left.

[0063] And when the shell 572 is pushed to the left by the output end of the electric telescopic rod 56, the base 571 will move to the left with the shell 572, and the base 571 will contact the I-shaped slider 61, and the base 571 will continue to move to the left, so that the base 571 applies a pushing force to the left on the I-shaped slider 61, and under the support of the cylindrical connecting rod 63 and the bending connecting rod 64, the first toggle rod 65 and the second toggle rod 66 move to the left together. At this time, the bending rod 624 on the auxiliary component 6 is subjected to the toggle force, and under the rotation connection of the ring 621, the scraper 623 evenly distributed on the round rod 625 rotates clockwise, and the edge of the bottom of the scraper 623 fits with the outer side of the first insulating column 1, and the auxiliary component 6 on the first insulating column 1 and the second insulating column 2 have the same structure, so that the dust attached to the surface of the first insulating column 1 and the second insulating column 2 can be scraped off through the bottom of the scraper 623, so that the surface of the first insulating column 1 and the surface of the second insulating column 2 are not easy to form a conductive liquid film;
[0064] When the gate needs to be opened, the output end of the electric telescopic rod 56 is retracted again, and the guide column 54 can be pulled to move to the right through the connection between the shell 572 and the base 571, thereby completing the gate opening.
