A ratchet 7 is arranged near the right side in the circular box 9. The right end of the rotating shaft 8 passes through the left wall of the ratchet 7 and is movably connected to the right inner wall of the take-up box 1 through a bearing. A clamping rod 16 is movably connected to the bottom of the inner cavity of the circular box 9. A limiting rod 11 is fixedly connected to the bottom of the inner cavity of the circular box 9, and a limiting hole matching the limiting rod 11 is provided at the bottom of the clamping rod 16. A telescopic spring 13 is fixedly connected between the limiting rod 11 and the top of the inner cavity of the limiting hole.

[0022] Working principle: during use, when the earphones need to be used in the square state, the earphone wire is directly pulled out. At this time, the take-up wheel 4 drives the rotating shaft 8 and the ratchet 7 to rotate forward. At this time, the clamping rod 16 vibrates continuously with the forward rotation of the ratchet 7, and will not affect the rotation of the ratchet 7. After being pulled to an appropriate length, the clamping rod 16 prevents the ratchet 7 from reversing. During this process, the first volute spring 5 is constantly stretched and keeps a tendency to restore to its initial state. When it is necessary to reel in the wire, just push the push block 15 downward to drive the clamping rod 16 to move downward to break away from the restriction on the ratchet 7. At this time, the first volute spring 5 returns to its initial state and drives the rotating shaft 8 to reverse, thereby reeling in the wire. The clamping plate 2 and the second volute spring 10 can be used to conveniently clamp it at the collar.
