Description

Technical Field

[0001] The utility model relates to the technical field of new energy, in particular to a precision hook. Background Art

[0002] When new energy vehicles are charging, one end of the charger needs to be inserted into the interface of the charging pile. When charging, the charging head of the new energy vehicle is charged at a certain height, and then the line of the charging head falls. The charger line needs to be suspended by a precise hook to prevent the gravity of the line from pulling the charging head down when the new energy vehicle is charging, and to prevent the charging head from being pulled by external force when the line is charging.

[0003] However, the precision hook is made of alloy, and its surface is relatively smooth. The line has a certain softness. When hanging the line, the line is easy to slide on the hook, and then the lines will slide and entangle with each other under gravity, and the blocking and fixing effect of the line is poor. In addition, the arc bending position of the hook is limited, and the line can only be hung once. Since the charger line is long, the line cannot be rotated back and forth on the hook, affecting the suspension of the charger line. Utility Model Content
