1. A rotary telescopic signal synchronization beauty instrument, comprising a main body, wherein a side wall of the main body is clamped with a main body upper cover, a head of the main body is sleeved with a detachable main body positioning head cover; a rotating disk, a heat sink, a rise-fall retractable body, and a soft rubber body are arranged between the head of the main body and the detachable main body positioning head cover; an electrical mainboard control component is mounted in the main body; the electrical mainboard control component includes a power switch, a function switch, a lithium battery, a USB charging socket, an LCD screen, and a direct-current speed-reducing motor;
an inner end of the head of the main body is provided with the direct-current speed-reducing motor; an (A) path of blade brush contact and a (B) path of blade brush contact are provided at an upper end of the head of the main body and an inner end of the detachable main body positioning head cover; a motor transmission shaft of the direct-current speed-reducing motor is provided with an (A) electrodeless current commutation copper tube for current signal conduction and the rotating disk; an A surface of the rotating disk is provided with an (B) electrodeless current commutation copper tube and a transmission circuit board; a B surface of the rotating disk is provided with a photoelectric device and the heat sink, the (A) path of blade brush contact is in contact with the (A) electrodeless current commutation copper tube on the motor transmission shaft of the direct-current speed-reducing motor; the (B) path of blade brush contact is in contact with the (B) electrodeless current commutation copper tube on the A surface of the rotating disk;
a current signal source arranged on the A surface and the photoelectric device arranged on the B surface of the rotating disk are configured to rotate around the rotating disk to work synchronously, current signals from the current signal source are configured to transmit from the blade brush contacts to the transmission circuit board on the A surface of the rotating disk through the electrodeless current commutation copper tube at the motor transmission shaft of the direct-current speed-reducing motor, and then configured to transmit to the photoelectric device on the B surface of the rotating disk through the transmission circuit board to emit lights as a light source;
an upper end of the B surface of the rotating disk is provided with a rise-fall retractable body and a spring; a lifting extend-retract function is achieved between the rise-fall retractable body and the rotating disk; and an outer surface of the head of the rise-fall retractable body is provided with the soft rubber body.
