[0042] Working principle:
[0043] The first step is that when using, the staff can first connect the external charger body 11 (the external charger body 11 is the existing technology, and its interior is mainly composed of an integrated rectifier, a filter and a voltage stabilizer, wherein the operation control logic of the series of units of rectification, filtering and voltage stabilization is based on the signals generated by the first magnetic switch 24, the second magnetic switch 25, the third magnetic switch 26 and the fourth magnetic switch 27, and transmits these signals to the PCB board assembly 28, and the PCB board assembly 28 accurately adjusts the voltage range according to the received signals, and finally provides the electric energy adjusted to the appropriate voltage to the corresponding power supply socket panel) with the power socket, and then the staff can choose to use the first socket panel 19, the second socket panel 21, the third socket panel 22 or the fourth socket panel 23 according to the power plug taken in the current area. At this time, the staff can toggle the sawtooth groove group 35 on the slip ring 34 so that the sawtooth groove group 35 A radial force is generated on the slip ring 34, thereby driving the rectangular plug-in structure to rotate. At this time, the rectangular plug-in structure will drive the rotating column 17 to rotate at the inner ring of the damping bearing 16. At the same time, the slip ring 34 will slide inside the arc-shaped slide groove 31. At this time, if the staff needs to use the first socket panel 19, the staff can rotate one side of the first socket panel 19 on the rectangular plug-in structure to the concave connection 12 by turning the slip ring 34. As the first socket panel 19 rotates, the first magnetic switch 24 under the first socket panel 19 will be located at the magnetic sensing block 38. At this time, the first magnetic switch 24 will send an electrical signal to the PCB board assembly 28, so that the external charger body 11 changes the path of the conductive distribution device 18 to control the first socket panel 19 so that the first socket panel 19 can be powered, so that the first socket panel 19 can supply electrical energy;
[0044] In the second step, when a path relationship is established between the first magnetic switch 24, the second magnetic switch 25, the third magnetic switch 26 or the fourth magnetic switch 27 and the magnetic sensing block 38 that are adapted thereto on the first socket panel 19, the second socket panel 21, the third socket panel 22 or the fourth socket panel 23, the first magnetic switch 24, the second magnetic switch 25, the third magnetic switch 26 or the fourth magnetic switch 27 that are in path will respectively send a signal to the PCB assembly 28, so that the conductive distribution device 18 opens the switch circuit that controls the first socket panel 19, the second socket panel 21, the third socket panel 22 or the fourth socket panel 23 that is in path therewith;
[0045] In the third step, by setting a plurality of second storage grooves 36 on the slip ring 34, the staff can select the first socket panel 19, the second socket panel 21, the third socket panel 22 or the fourth socket panel 23 and adjust it to the concave connection 12 for use. Since the four edges of the rectangular plug-in structure are parallel to the second magnetic block 37, when the staff rotates the rectangular plug-in structure and the rectangular surface of the first socket panel 19, the second socket panel 21, the third socket panel 22 or the fourth socket panel 23 is parallel to the concave connection 12, a corresponding adsorption force can be generated to make the second magnetic block 37 and the first magnetic block 33 on the same side of the concave connection 12 produce attraction, thereby providing an auxiliary limit guide for the staff to select the first socket panel 19, the second socket panel 21, the third socket panel 22 or the fourth socket panel 23, thereby improving convenience.
