One end of the cavity is close to the power take-off head and has a through hole, while the other end of the cavity is away from the power take-off head. A locking rod is provided inside the cavity, and the center of the locking rod is rotatably connected to the cavity. One end of the locking rod is fixed with an L-shaped locking hook that passes through the through hole. One end of the locking rod is located outside the cavity. The other end of the locking rod is fixed with a button. One side of the cavity is away from the discharger body and has a through hole two that matches the button. The other side of the cavity is close to the discharger body. One side of the button is provided with a spring and is elastically connected to the side of the cavity close to the discharger body through the spring. The other side of the button is located outside the cavity after passing through the through hole two under the support of the spring. One side of the through hole one is close to the discharger body, and the other side of the through hole one is away from the discharger body. A gap is formed between the locking hook and the side of the through hole one away from the discharger body.

[0007] One end of the discharger body is a power-taking head, and the other end is an external discharge socket with locking grooves on both its left and right outer side walls.

[0030] In Example 1, the charging head 2 is plugged into the charging port on the discharge vehicle body. Simultaneously, the locking hook 8 is inserted into a matching hook groove on the vehicle body. The charging vehicle body is plugged into the external discharge socket 3 via the charging plug. The locking block on the charging plug cover matches the locking groove 4, allowing the locking block to be inserted from one open end of the locking groove 4. Then, driven by the rotation of the locking cover, the locking block is forced into the closed end of the locking groove 4, thus locking both ends of the discharger. This prevents the connection from loosening during actual use. To unlock, the operator simply presses button 9, which rotates the locking rod 7, causing the locking hook 8 to disengage from the hook groove and rotate into the gap. Simultaneously, to unlock the charging plug, the locking cover is rotated in the opposite direction.

[0031] In the second embodiment, when assembling the locking rod 7 with the cover 20, the locking rod 7 is inserted into the U-shaped groove 26 from the open end of the cover 20 through the rotating shafts 25 on its left and right sides. At the same time, one end of the spring 11 is sleeved on the button 9. At this time, the button 9 is located in the second through hole 10, and the locking hook 8 passes through the first through hole 6. When the assembled cover 20 is inserted into the assembly groove 19 through the assembly insertion port 21 from its open end, the other end of the spring 11 abuts against the bottom of the assembly groove 19. At the same time, the support block 27 contacts the bottom of the assembly groove 19 through its arc surface. At this time, the rotating shaft 25 slides to the bottom of the U-shaped groove 26. This design facilitates the rotation of the locking rod 7 while limiting the locking rod 7 in both its length direction and the direction perpendicular to it, and also facilitates installation and disassembly. Finally, the socket cover 13 is installed, so that the cover 20 is positioned in the mounting groove 28 under the pressing action of the socket cover 13, thereby making the installation and disassembly of the charger locking structure convenient and quick.
