[0002] With the increase in car ownership, car chargers are favored by many car owners because they can charge mobile phones and other electronic products at any time while driving and are easy to carry. Car chargers are usually installed at the cigarette lighter port, because the cigarette lighter port (also known as the vehicle power socket or auxiliary power socket) is usually located in a convenient position inside the vehicle and has the function of providing power for vehicle-mounted devices.

[0003] Moreover, most car chargers are designed with plugs that match the cigarette lighter port, so they can be easily inserted and fixed in the cigarette lighter port. In addition, car chargers are usually equipped with a variety of interfaces to meet the charging needs of different electronic devices.

[0004] Over time, the contact part between the car charger's plug and the cigarette lighter port may lose its original fastening force due to wear and aging. During driving, the vehicle may vibrate due to various reasons, and the contact between the car charger and the cigarette lighter port may be unstable, which may cause interruption of the charging process of the electronic device or low charging efficiency. This means that users need to take longer to charge their devices, especially when they urgently need power during driving, which may cause inconvenience to users. Utility Model Content

[0027] See also Figures 1 to 3 The fastening device 4 includes a shell 43, a fastener 41 and an elastic reset member. The fastener 41 is movably arranged on the plug 12 and is equipped with an elastic reset member that enables the fastener 41 to move toward the inside of the plug 12. The elastic reset member is a compression spring 42. A protrusion 411 is provided at one end of the fastener 41 extending toward the outside of the plug 12, and a button 412 is provided at the other end extending toward the outside of the plug 12.
