The present invention provides a structural improvement of a charging gun, in particular, a charging gun structure in which the upper and lower grips of the gun body are longitudinally assembled, and the butt joint is assembled on the side of the inner housing space by the gun body, and the other side is assembled. The rivet pressure tube is assembled on the top of the upper grip switch device, and the upper and lower grips are assembled and combined in the upper and lower grips to prevent the penetration of moisture inside the gun body and prolong the service life of the charging gun.

According to the increasing global warming phenomenon, countries around the world continue to advocate energy conservation and carbon reduction to slow down the phenomenon of global warming, and also raise awareness of environmental protection. In the daily life of clothing, food, shelter, entertainment, etc. When a large amount of waste is disposed of, it will also generate a large amount of waste gas, carbon dioxide, etc., which affects the environmental quality when handling various types of waste. Among them, vehicles, locomotives, airplanes or ships that pass through various modes of transportation As a means of transportation, but because various vehicles use fuel such as gasoline or diesel, they will emit exhaust gas during operation, which is the culprit of serious air pollution. Vehicles are an indispensable means of transportation in daily life. How to use environmental protection appeals and the ability to use mobility tools has become a problem that modern people must face and solve.

In order to solve the problem of exhaust emissions from vehicles, some operators have developed electric vehicles, which are driven by electric energy to drive the vehicles without exhausting them. The pollution caused by air and environment has also become a target of vigorous promotion by all countries in the world. It encourages people to change electric vehicles and locomotives as transportation tools to reduce exhaust emissions, thereby improving the air quality of the living environment and reducing the environment and air. For pollution and destruction, vehicles such as electric cars or locomotives are used. One of the most important conditions is that vehicles such as steam and locomotives must be charged to provide energy for operation of steam and locomotives. When the user is charging at home or charging at a fixed charging station, the vehicle can be charged by means of a charging gun for vehicles such as steam and locomotives; currently used charging guns have their handles transmitted through the left and right opposite directions.
