[0015] The working principle of this technical solution is that when the first button cap is not pressed, the fire needle is located in the connecting tube under the action of the spring. According to the patient's physical condition, the third controller is adjusted so that the third controller starts the driving member, and the driving member drives the travel switch to move to a suitable position.

[0016] The first temperature and the second temperature are set by the first controller; the first controller turns on the heating circuit, the heating circuit heats the fire needle, and the temperature sensor monitors the temperature in the heating tube and transmits the signal to the first controller; after heating for a period of time, when the temperature detected by the temperature sensor reaches the first temperature, the heating circuit is disconnected and the insulation circuit is connected; when the temperature monitored by the temperature sensor drops to the second temperature, the first controller disconnects the insulation circuit and turns on the heating circuit, and repeats this process.

[0017] After the heating unit is started for a period of time, the infrared transmitter is turned on, and the medical staff holds the gripping rod so that the infrared rays emitted by the infrared transmitter are just at the position to be acupunctured. The fingers quickly press the first button cap, and the conductive block on the first button cap connects the circuit between the electromagnet and the power supply, so that the electromagnet is energized, and an attractive force is generated between the electromagnet and the connecting rod. The attractive force pulls the connecting rod to move, and the connecting rod drives the fire needle to move outside the transparent cover to achieve acupuncture. At this time, the spring is in a stretched state. When the limit block on the connecting rod collides with the travel switch, the travel switch disconnects the circuit between the electromagnet and the power supply; at the same time, the second controller quickly connects the discharge circuit to release the current on the electromagnet, so that the attraction between the electromagnet and the connecting rod disappears instantly; the connecting rod returns to its original position under the elastic force of the spring, driving the fire needle to retract into the connecting tube. Then the next part can be acupunctured.
