AI Technical Summary
The retractors of existing headphones are prone to damage, causing friction damage to the headphone cable and preventing it from retracting automatically.
Design a pull-out and folding cable device based on headphones, which achieves stable pulling and folding of the headphone cable through a stretching mechanism and a buckle limiting structure.
Effectively prevents damage to the headphone cable, ensuring that the headphone cable is not easily pulled during use, and avoids tangling and friction damage.
