When the charging gun 4 is used, the charging line is pulled while the roller A343 and the roller B333 rotate. The roller B333 drives the gear C334 to rotate, and the gear C drives the gear D37 to rotate, thereby driving the take-up reel B to rotate and release the line. After releasing the line, the charging line tends to be recovered due to the force of the spring 223. When the release of the line is stopped and the brake line 53 is pulled alone, the pulley A352 is forced to move downward, and at the same time drives the roller C351 to rotate, so that the support block 354 presses against the gear C to achieve the purpose of preventing the charging line from being recovered.

The outer wall of the electric gun housing 41 is slidably matched, the sliding switch 421 is fixed to the positioning rod 422, and the sliding switch 421 is fixed to the waterproof suction cup 423. The positioning rod 422 is slidably matched with the vertical groove of the L-shaped groove. In the initial state, the positioning rod 422 is at the rearmost end of the L-shaped groove. When charging, the sliding switch 421 is pushed to move the positioning rod 422 to the frontmost end of the vertical groove of the L-shaped groove. At this time, the sliding switch 421 is rotated to make the positioning rod 422 enter the horizontal groove of the L-shaped groove, and then the tension of the brake line is used to lock the positioning rod 422 in the horizontal groove of the L-shaped groove.

[0032] A charging plug is provided at one end of the charging gun housing 41 , and a slot is provided above the charging plug. A positioning buckle 431 is provided in the slot.
