What is the trick for a loose cigarette lighter socket?

[OIsabelle]

Cigarette lighter socket becomes loose can be fixed by using a small screwdriver to slightly bend the metal contact inside the socket towards the center to tighten it. The reason for the loose cigarette lighter socket is due to the failure of the spring contacts inside. The specific steps are as follows: 1. Find a piece of steel wire about 2mm in diameter and make a small hook at the front end. 2. Then flatten the front end of the hook with a hammer. 3. Use a flashlight to illuminate the cigarette lighter socket, identify the spring contacts, and gently bend them inward with the hook (there are two symmetrical contacts). Many cigarette lighter sockets tend to become loose over time. When not in use, it's advisable to cover the cigarette lighter socket with its cap to prevent water from entering.
