[0002] With the rapid development of social economy, electric vehicles, as a new product, have the advantages of environmental protection, safety, economy and practicality, and are gradually accepted by people, and their presence in the market has increased accordingly. However, as a new product, the supporting services and usage of electric vehicles are still far behind those of traditional gasoline vehicles, and are not perfect. Among them, the main energy source in electric vehicles is batteries. When the battery power is scarce, electric vehicles can only be driven again after parking and charging.

[0003] The charging gun is an important device used to charge electric vehicles. It can be simply understood as a bridge connecting electric vehicles and charging facilities. The bidirectional charging gun can charge the vehicle and supply power to the outside.

[0004] In the prior art, when using most bidirectional charging guns, the power cord and the adapter cable need to be plugged in through the connection sleeve and the connector before charging can be performed. However, when the connector and the connection sleeve are plugged in, there is no component to fix the two, resulting in a lack of reliability when the two are connected, and they are easily pulled off, making it impossible to charge. In addition, most bidirectional charging guns cannot conveniently power other small electronic devices, and are not practical enough. Therefore, it is necessary to redesign a bidirectional charging gun for vehicles to address the above problems. Utility Model Content
