As shown in fig. 1 and 2, the lateral length of the element box 4 is greater than the lateral length formed by the charging jacks USB of the four wired charging modules, and the length of the supporting plate 3 is greater than the length and width of the four mobile phones put together. The upper end of the detecting head of the photoelectric switch D4 and the upper outer end of the element box 4 are in a plane. In the charging control circuit, a pin 3 of a positive power supply output end and a pin 2 of a negative power supply input end of the photoelectric switch D4 are respectively connected with two ends of a power supply input end of the relay K2 through wires. In the detection circuit, a pin 3 of a positive power supply output end and a pin 2 of a negative power supply input end of a microwave detection module D2 are respectively connected with two ends of power supply inputs of two relays K1 and K3 through wires.
