The socket is too loose and the plug keeps falling off.

If the socket is too loose and the plug keeps falling off, you can try the following solutions:

1. Replace the socket: If the socket is used for a long time and the power plug cannot be firmly connected, the socket contact may be aging or damaged. It is recommended to replace the socket at this time.

2. Reinforce with buckle or tape: You can reinforce the connection between the plug and the socket with tools such as buckle or tape, which can enhance the friction between the plug and the socket and prevent the plug from falling off easily.

3. Add a spacer to the plug: Sometimes the plug will wear out after being used for a long time, resulting in an oversized socket. At this time, an isolation ring can be added to the head of the plug to increase the diameter of the plug, thus improving the fit between the plug and the socket.

4. Use a converter: If the plug and socket don't match, consider using a plug converter to connect the mismatched plug and socket to prevent the plug from always falling off.

In short, if the socket is too loose, you need to pay special attention when using it to avoid potential safety hazards. If there is no other better solution, it is recommended to replace the socket to ensure the safety of household electricity.
