[0054] The pressing end 22 has a receiving hole 223, and the first spring 7 is partially located in the receiving hole 223.

[0055] Example

[0056] The housing 1 has a first mounting groove 11 and a second mounting groove 12 that are interconnected. The second mounting groove 12 is located on the handle 9 of the charging gun, and the handle 9 also has a through hole 91 to provide space for the installation and operation of the button 6. The side wall of the first mounting groove 11 has a mounting part 111, on which a first pin 3 is mounted for hinged connection of the locking rod 2.

[0057] The locking lever 2 is hinged to the first mounting groove 11 of the housing 1 via a first pin 3. One end of the locking lever 2 has a locking hook 21 for locking with the charging interface; the other end is a pressing end 22, which has a pressing platform 222. The pressing part 42 presses against the pressing platform 222, and the upper surface of the pressing platform 222 is lower than the upper surface of the pressing end 22. This design helps the pressing part 42 of the control lever 4 to drive it more precisely. Simultaneously, the pressing end 22 also has a positioning hole 221 and a receiving hole 223, such as... Figure 3 As shown, the receiving hole 223 partially accommodates the first spring 7, which elastically supports the pressing end 22 and provides power for the reset of the locking rod 2. The first pin 3 is located between the locking hook 21 and the pressing end 22, allowing the locking rod 2 to rotate around the first pin 3 as a fulcrum.

[0058] The control lever 4 is hinged to the second mounting groove 12 of the housing 1 via the second pin 5, and is at least partially located in the mounting groove. One end of the control lever 4 is provided with a connecting part 41, and the other end is provided with a pressing part 42. The second pin 5 is located between the connecting part 41 and the pressing part 42, so that the control lever 4 can rotate with the second pin 5 as a fulcrum.

[0059] In another embodiment, the pressing part 42 has a cavity 421, such as Figure 2 As shown, the cavity 421 is fitted with the pressing end 22. The bottom of the cavity 421 has a positioning post 422, which cooperates with the positioning hole 221 of the pressing end 22 to achieve a more stable connection and transmission between the control rod 4 and the locking rod 2. The upper surface of the pressing part 42 is flush with the upper surface of the pressing end 22, ensuring the compactness of the structure.

[0060] Button 6 is fixedly connected to the connecting part 41 of the control lever 4 and passes through the through hole 91 on the gun handle 9, such as Figure 6 As shown, this design facilitates user pressing. A second spring 8 is located inside the button 6. One end of the second spring 8 is connected to the inner wall of the button 6, and the other end is connected to the connecting part 41 of the control lever 4, providing automatic reset force after the button 6 is pressed.

[0061] When the charging gun needs to be unlocked, the user presses button 6. Button 6 moves the connecting part 41 of the control lever 4 upward. Since the control lever 4 uses the second pin 5 as a fulcrum, the pressing part 42 will apply downward pressure, thereby driving the pressing end 22 of the locking lever 2 downward. The locking lever 2 rotates around the first pin 3 as a fulcrum, causing the locking hook 21 to lift, thus unlocking the device. After releasing button 6, under the action of the second spring 8, button 6 moves the control lever 4 back to its original position. At the same time, under the action of the first spring 7, the locking lever 2 also returns to its initial position, and the locking hook 21 is once again in a locked and ready state.

[0062] The above descriptions are merely a few embodiments of this utility model. Those skilled in the art can make various modifications or variations to the embodiments of this utility model based on the content disclosed in the application documents without departing from the spirit and scope of this utility model.
