The protective sleeve 1 and the protective sleeve 2 can be rotated at both ends of the mounting plate 22 through the rotating shaft 23, so as to adjust the angle between the protective sleeve 1 and the protective sleeve 2.
[0030] A slot 7 is provided at one end of the protective sleeve 1, and one end of the insertion strip 8 is slidably installed inside the protective sleeve 2, a limit block 24 is installed at one end of the insertion strip 8 located inside the protective sleeve 2, a limit groove is installed inside the protective sleeve 2, and the limit block 24 slides inside the limit groove to prevent the insertion strip 8 from being separated from the protective sleeve 2, and magnets 25 that cooperate with each other are installed inside the insertion strip 8 and the slot 7. The insertion strip 8 can be inserted into the slot 7 and fixed by the magnet 25, so that it can be sleeved on the surface of the fire water pipe.
[0031] An insulation layer 4 is installed inside the protective cover 1 and the protective cover 2, and heating components 5 are installed on both sides of the insulation layer 4. The heating components 5 are connected to the power supply through wires. This is a conventional technical means and will not be explained again.
