The centrifugal force generated by the counterweight block when the fixed box rotates is used to drive the sliding rod to change the meshing state of the ratchet gear and the toggle lever. The damping effect of the buffer medium on the movement of the piston plate is combined to adjust the reset speed, so that the suspension line can extend freely with the charging gun body when moving and can achieve self-locking at any position through the one-way locking of the ratchet when stationary. At the same time, the high-speed rotation mechanism is triggered by the secondary pulling, and the energy storage characteristics of the winding spring are used to make the suspension line automatically reel after the limit is released. The centrifugal force and elastic reset are combined to achieve the desired effect. The combined dual-action mechanism improves the reliability of the component, and cooperates with the buffer device to effectively suppress mechanical impact, ensuring smooth retraction and release of the connecting cable while significantly reducing mopping wear, extending the service life of the connecting cable, and avoiding leakage of internal components of the connecting cable, thereby improving the overall safety of the device. During operation, the suspension line can be self-locked at any position, making the device suitable for different charging application scenarios, thereby improving the overall applicability of the device. At the same time, the secondary triggered automatic rewinding can realize automatic resetting and sorting of the connecting cable, improve the resetting efficiency of the connecting cable, and ensure the orderly placement of the connecting cable when not in use, thereby avoiding damage to the connecting cable.

[0028] 2. In the present invention, by providing a protective component, when the charging gun body is not in use, the protective sleeve protects the plug head, which can effectively prevent water stains such as rain from contacting the plug head and causing a short circuit that damages the charging gun body. During use, the protective sleeve can fit tightly against the vehicle wall, so that the plug head is in a sealed state, which can effectively protect the plug head and the vehicle charging port, improve the protection and waterproofness, and extend the service life of the charging gun body.

[0029] 3. In the present invention, by providing a power-off component, when the charging gun body is not in use, the power board and the power block are in a separated state. At this time, the plug head is in a power-off state and can protect the internal components. When the plug head is separated from the vehicle charging port, the circuit is automatically cut off, completely eliminating the risk of leakage or short circuit caused by idle equipment or accidental touch. The separation between the components avoids overheating of the plug head when it is powered on, improves the heat dissipation effect, makes the device suitable for safety protection in complex environments such as humidity or high temperature, and improves the safety of the device.
