The charging gun 100 includes a gun body 110 and a gun head 120 connected to the gun body 100. The charging head 200 includes a socket 210 and an end cap 220 connected to the socket 210. The charging head 200 is connected to the charging interface of the device to be charged through the socket 210. The charging gun 100 is plugged into and unplugged from the socket 210 through the gun head 120. The gun body 110 is used for users to hold and plug and unplug the charging head 200. Typically, the gun body 110 is connected to an outwardly extending cable. Only a portion of the cable at the end of the gun body 110 is shown in the attached figure.
[0024] Furthermore, the gun body 110 is provided with a latch 130 for locking / unlocking the connection between the charging gun 100 and the charging head 200. When the gun body 110 is inserted into the charging head 200 to charge electric vehicles, electric bicycles, and other devices, it is secured to the charging head 200 by the latch 130, preventing it from being pulled out and ensuring stable charging. The gun head 120 is provided with an outwardly extending insertion end 121, and the socket 210 is provided with a connecting cavity 211 that matches the shape of the insertion end 121. The end face of the insertion end 210 has a "D" shaped structure and matches the shape of the connecting cavity 211. The matching shapes of the two facilitate positioning and connection, improve connection stability, and make it easier for the user to hold the charging gun 100 and insert it into the charging head 200 for charging.

The inner side of the upper shell also has a bracket for connecting the hook 130. The hook 130 has a shaft hole in the middle. Through the connection of the bracket and the pivot, the hook 130 can be rotated by pressing the button end. Generally, the pivot also has an elastic element that provides a restoring force to the hook 130. The button end 131 and the hook body end 132 are linked through the pivot. When the button end 131 is pressed, the hook 130 rotates around the pivot, causing the hook body end 132 to move in the unlocking direction and the hook body end 131 to move away from the hook hole 223, thereby releasing the charging head 200. Conversely, when the flip cover button end 131 is pressed, the hook 130 is reset under the action of the elastic element, causing the hook body end 132 to engage with the hook hole 223, and the hook 130 returns to the locking direction to fix the charging head 200. The pivot can be a pin that passes through the hook 130 and is mounted on the bracket connected to the gun body 110 to allow the hook 130 to rotate freely. The elastic element can be a torsion spring to provide a reset force for the hook 130.
[0026] Furthermore, the gun head 120 is provided with a switch base 113 for powering on or off. The switch base 113 is installed inside the gun body 110. The switch base 113 is provided with a downwardly extending power-off hardware, which is a conductive component. The power-off hardware can be connected to the circuit of the charging gun 100 through a wire. The switch base 113 is provided with a movable contact above the power-off hardware. When the contact contacts the power-off hardware, the circuit is closed; otherwise, the circuit is open. When the hook 130 rotates, its bottom can contact the push contact to control the contact between the contact and the power-off hardware. The structure of the switch base 113 is not limited to this embodiment. In other embodiments, the switch base 113 can be a micro switch with a different structure to power on or off the charging gun 100 when the hook 130 rotates. When the user holds the charging gun 100, pressing the button end 131 will rotate the hook 130 and de-energize the charging gun 100. When the charging gun 100 is inserted into the charging head 200, releasing the button end 131 will energize the charging gun 100 for normal charging. When the user needs to remove the charging gun 100, pressing the button end 131 will disengage the hook end 132 from the hook hole 223 and de-energize the charging gun 100. The user can then remove the charging gun 100 without accidentally touching it and causing electric shock, ensuring safety during use.
