The transmitting coil 5 can freely deflect in 360 degrees by taking the gravity center of the tumbler module 3 as an axis, and the rotating angle and distance of the transmitting coil 5 by taking the gravity center of the tumbler as the axis are controlled by the first magnetic control module and the second magnetic control module.
