Abstract
The utility model discloses a plug capable of being pulled with a single hand. The plug can be pulled with a single hand, solves the problem that it is inconvenient to pull a plug from a movable socket, and can protect metal pins against damage. A telescoping mechanism is disposed in a plug body. By using the pushing force of fingers as the main power and the elastic force of a spring as the restoring force, the telescoping mechanism enables an indexing rotary drum and a sliding claw in the shell to tend to slide relative to each other, so that the tendency of relative rotation is generated; when the two rotating wheels move downward to certain positions along protruding strips of guide rails on the shell by the actions of force, the sliding claw and the indexing rotary drum rotate practically, ends of the protruding strips of the guide rails are embedded in shallow grooves in an indexing claw and the metal pins extend out; and when a button is further pressed downward for a certain distance, a sliding claw sleeve and the indexing claw rotate, the protruding strips of the guide rails enter deep grooves again and the metal pins retreat back into the shell because of the elastic force of the spring. Therefore, the objectives of pulling the plug with the single hand and protecting the metal pins are achieved.
