The access button 5 extends into the outside of the wiring panel insertion slot, and the lock tongue on the access button passes through the sliding slot 121 to lock the wiring panel or the limit slot.

[0036] Threaded locking columns 92 are fixed on both sides of the base, and locking holes are opened on the control panel, automatic retracting panel, installation panel and packaging panel. Screws pass through the through holes to fix the control panel, automatic retracting panel, installation panel and packaging panel to the base.

[0037] like Figure 6-7 As shown, the automatic retraction mechanism includes a shell 115, a rotating groove 110 is opened in the shell, a clamping column 116 is fixed at the center of the rotating groove, a straight groove is opened on the clamping column, a winding drum 117 passes through the clamping column, and a through hole 119 for the clamping column to pass through and a through hole for the connecting wire to pass through is opened on the winding drum 117.

After passing through, the connecting wire is wound on the winding drum layer by layer, and the connecting wire exit section 113 is led out from the other side of the shell.

[0038] When the connecting wire outlet section 113 is stretched, the winding drum 117 rotates accordingly, and the winding drum pulls the coil spring 118, and the coil spring curls and contracts accordingly. When the connecting wire outlet section 113 is released, the coil spring automatically expands, and the winding drum rotates in the opposite direction. The connecting wire outlet section 113 is gradually wound onto the winding drum 117, realizing automatic contraction of the connecting wire.

[0039] like Figure 8-9As shown, a triangular prism-shaped notch 21 is provided on the plug panel and the limit groove, and the access button includes a locking sleeve 51, a button 52, a connecting rod 53, a lock tongue 55, a spring 56, a support 57 and a spring piece 59. The button is fixed to the top of the connecting rod, the connecting rod is inserted into the locking sleeve, the spring is arranged at the bottom of the locking sleeve, and the bottom of the connecting rod is supported on the spring. Telescopic holes 54 are provided on both sides of the locking sleeve, the bottom of the connecting rod is hollow, and an extension hole 58 is provided on each side of the cavity.

The lock tongue 55 can extend from the telescopic hole of the locking sleeve 51 and extend into the sliding slot to lock the plug panel 2.

[0040] When the button 52 is pressed, the connecting rod 53 moves downward, and the lock tongue 55 at the bottom of the connecting rod squeezes the spring under the pressure of the telescopic hole. The lock tongue slides from the telescopic hole 54 into the connecting rod in the locking sleeve 51 and abuts against the inner wall of the locking sleeve 51 and then slides downward to complete the unlocking. At this time, the wiring panel 2 can be taken out from the packaging panel 13 for easy use. The connecting rod is pushed upward when the spring is reset, and the lock tongue 55 gradually slides upward. When the lock tongue slides to the telescopic hole 54, it extends from the telescopic hole 54 under the ejection action of the spring and locks the wiring panel 2.

[0041] A specific application of this device is: the first multi-interface charging power cord 3 and the second multi-interface charging power cord 4 both include a three-in-one charging connector and a limit slot. The three-in-one charging connector includes an Apple mobile phone charging connector, a Type- charging connector and an Android mobile phone charging connector. The three-in-one charging connector is stuck in the limit slot. The width of the limit slot is greater than the width of the limit socket. When taking it out, press the access button 5 to complete the unlocking. At this time, the plug panel can be removed from the packaging panel 13, and the plug panel 2 can be pulled to a suitable power-taking position. The connecting wires of the plug panel can be prevented from extending too much under the constraint of the automatic retraction mechanism, which is more beautiful during use. Similarly, the first multi-interface charging power cord 3 and the second multi-interface charging power cord 4 can be removed from the packaging panel 13 to directly charge the mobile phone. The wireless self-provided charging cable is more convenient and practical.
