[0024] Furthermore, the front and rear ends of one side of the U-shaped cooling coil 2 are respectively connected with an inlet pipe 202 and a return pipe 203. The inlet pipe 202 and the return pipe 203 both extend out of the lower end surface of the protection box 1 and are connected to the cooling device. The cooling water is transported to the U-shaped cooling coil 2 through the inlet pipe 202 by the cooling device. The cooling water cools the heat-conducting support plate 201. The temperature measuring device is installed on the heat-conducting support plate 201, and the temperature measuring device is cooled by the heat-conducting support plate 201.

[0025] Furthermore, a rotating groove 301 is provided inside the rotating seat 3, and a worm 302 is rotatably connected to one side of the rotating groove 301.
