[0020] As Figures 1-4 shown, the plug-in end of the charging gun extension cable includes a plug-in end body 1. A button 2 is installed on the plug-in end body 1. One end of the button 2 is rotatably connected to the plug-in end body 1. A connecting rod 3 and a spring 4 are installed inside the button 2. The middle of the connecting rod 3 is rotatably connected to the plug-in end body 1. The other end of the connecting rod 3 is connected to a buckle 5. A buckle through hole 6 for the buckle 5 to insert is provided on the plug-in end body 1. The spring 4 abuts against the button 3 and the plug-in end body 1 respectively. It can be understood that the plug-in end body 1 and the button 2 can both be made of hard plastic material, etc.

[0021] Specifically, a button mounting portion 7 is provided on the gun insertion end body 1. An installation groove 8 is formed in the button mounting portion 7, and the installation groove 8 communicates with the buckle through hole 6. The button 2 is rotatably connected to the gun insertion end body 1 through a rotating rod 9. Rotating rod through holes 10 adapted to the rotating rod 9 are formed on the outer sides of both the button mounting portion 7 and the button 2. A first buckle 11 and a second buckle 12 are sequentially arranged on the side surface of the connecting rod 3 from left to right.
