A winding portion 1021 protrudes from the upper end of the cable reel 102. The cable 103... 3. The cable 103 is wound around the winding section 1021, with both ends of the cable 103 simultaneously approaching or moving away from the winding reel 102, and the cable lengths on both sides being equal. A cable passage hole 1012 is recessed on each of the two side walls of the housing 101, and both ends of the cable 103 pass through the cable passage hole 1012. A first short shaft 1013 protrudes from one side of the receiving groove 1011, and the rear end of the planar spiral spring 104 is fixedly connected to the first short shaft 1013. A support sleeve 1022 protrudes from the lower end wall of the reel 102. The lower end of the support sleeve 1022 slides against the bottom of the receiving groove 1011. The front end of the planar spiral spring 104 is fixedly connected to the support sleeve 1022. The two ends of the planar spiral spring 104 are respectively wound around the first short shaft 1013 and the support sleeve 1022. The planar spiral spring 104 drives the reel 102 to rotate, thereby achieving automatic winding. A through groove 1014 is recessed on one side of the upper end of the housing 101. The unlock button 105 is movably inserted through the through groove 1014. A limiting plate 1051 protrudes from the lower end of the unlock button 105.

The second short shaft 1015 is rotatably embedded in the through hole 1023, which plays a limiting role for the winding reel, making the winding reel rotate more smoothly.

[0022] Specifically, the inner bottom wall of the housing 101 is provided with a first limiting groove 1016, the lower end of the unlock button 105 is recessed with a second limiting groove 1052, and the two ends of the pressing spring 106 are respectively embedded in the first limiting groove and the second limiting groove 1052, which play a limiting role for the pressing spring.

[0023] Specifically, the front end of the limiting plate 1051 is provided with a limiting part (not shown), and the lower end wall of the winding reel 102 is provided with a plurality of third limiting grooves (not shown) along the circumferential direction. The limiting part is embedded in the third limiting groove, so that the limiting plate can securely lock the winding reel.

[0024] Specifically, the cross-sections of the limiting part and the third limiting groove are both triangular or arc-shaped, which makes it easy for the limiting plate to securely lock the winding reel and prevent it from rotating and losing its locking function.

[0025] Specifically, the working principle and process of this utility model are as follows:

[0026] The housing has an internal receiving groove adapted to a cable reel, which is rotatably embedded in the receiving groove. A winding portion protrudes from the upper end of the cable reel, and the cable is wound around the winding portion. Both ends of the cable are simultaneously close to or away from the cable reel. A cable passage hole is recessed on each side wall of the housing, through which the two ends of the cable pass. A first short shaft protrudes from one side of the receiving groove, and the rear end of a planar spiral spring is fixedly connected to the first short shaft. A support sleeve protrudes from the lower end wall of the cable reel, and the lower end of the support sleeve slides against the bottom of the receiving groove. The front end of the planar spiral spring is fixedly connected to the support sleeve, and both ends of the planar spiral spring are wound around the first short shaft and the support sleeve, respectively. The planar spiral spring drives the cable reel to rotate, and the housing... A groove is recessed on one side of the upper end, through which the unlock button can move up and down. A limiting plate protrudes from the lower end of the unlock button, with the front end of the limiting plate abutting against the lower wall of the cable reel. A pressing spring is located at the lower end of the unlock button, with both ends abutting against the inner bottom wall of the housing and the lower end of the unlock button, respectively. This allows the cable to automatically retract into the housing, saving space and preventing the cables from tangling and getting damaged. When the cable is in use, it can be pulled out, and it automatically locks itself when pulled out. The cable lengths on both sides are equal. When not in use, simply press the unlock button to automatically retract the cables from both ends into the housing. This effectively solves the problem of messy cables and also effectively prevents the cables from being damaged due to long-term bending. It is easy to carry and highly practical.
