[0036] Working principle: When using the device, first replenish the carbon liquid inside the crucible 2, start the power supply, and the carbon liquid inside the crucible 2 begins to be heated by the heating column 10. When it is heated to a sufficient temperature, the threaded rod 23 is driven to rotate by rotating the motor 7, driving the slider 4 to descend.
