[0002] An electric mosquito killer is also called an electric mosquito lamp, an electric insect killer, etc. It utilizes the phototaxis of mosquitoes, attracts mosquitoes, insects, etc. through a mosquito attracting lamp, and makes them die after touching a high-voltage power grid, so as to achieve the effect of killing mosquitoes.

[0003] A high-voltage head is also called a high-voltage bushing, etc. It can allow a high-voltage conductor to pass through a partition with a different potential from it, playing the roles of insulation and support.

[0004] The utility model with the authorization announcement number of CN205511775U discloses a high-voltage head. It includes a high-voltage head support plate and a high-voltage grid fixing connecting rib. On the high-voltage head support plate on both sides of the high-voltage grid fixing connecting rib, a left high-voltage grid fixing column and a right high-voltage grid fixing column are respectively installed. The left high-voltage grid fixing column and the right high-voltage grid fixing column are connected and fixed together through the high-voltage grid fixing connecting rib. On both sides below the high-voltage head support plate, a left high-voltage head support leg and a right high-voltage head support leg are respectively installed radially and vertically. The lower ends of the left high-voltage head support leg and the right high-voltage head support leg are both provided with a convex platform extending outwards.

[0005] The application has the following deficiencies: First, because the left high-voltage grid fixing column and the right high-voltage grid fixing column are connected and fixed together through the high-voltage grid fixing connecting rib, insect corpses are likely to accumulate on the high-voltage grid fixing connecting rib, resulting in a short circuit and sparking between the high-voltage heads, thus burning out the high-voltage head and the mosquito killing device, and there are potential safety hazards; Second, the left high-voltage grid fixing column and the right high-voltage grid fixing column are integrally formed, and the distance between the two cannot be adjusted.
