The air outlet of the hot air blower is connected to the inside of the box body through a pipeline. The mounting frame is arranged inside the box body, and the standard parts are arranged on the mounting frame. The mounting frame is also provided with a fixing part for fixing the measured thermometer. The side wall of the box body is provided with an observation window made of transparent material for observation by an operator.
