[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. Through the cooperation of the sealing ring and the sealing plug, the two sides of the end of the carbon fiber heating tube are sealed to improve the sealing effect.

[0020] 2. Under the action of the spring, the contact pressure between the sealing plug and the carbon fiber heating tube is increased, so that the sealing plug is tightly attached to the port of the carbon fiber heating tube to prevent the sealing plug from loosening and aging, which may cause leakage.
