[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The outside of the lamp tube of this utility model is coiled with a heating wire, which can control the temperature of the lamp tube through the heating wire, and can also illuminate the lamp tube, so that heating and lighting can be controlled at the same time, which improves functionality. A lamp tube cover is provided on the outside of the lamp tube, which can provide explosion-proof protection and improve the safety of the lamp tube.

[0014] 2. The lamp tube cover of this utility model is provided with locks at both ends, and the locks can be manually turned and controlled for easy disassembly. An external connector is provided at the end of the lock, and a pin hole is provided at the port of the external connector. The pin hole can be used to assemble with the pin at the end of the power connector. The power connector is provided on the limiting ear of the ear frame for easy disassembly, and a waist hole is provided on the top of the ear frame, which can be hoisted and fixed through the ear frame, making it convenient for installation and disassembly of the lamp tube cover.
