The working principle is as follows: when the detection device is used, the T-shaped sliding block 507 is backwards slid, the fixing clamp edge 5021 leaves the fixing groove 5071, the second fixing strip 502 is rotated by 90 degrees, NHN insulating paper is placed on the upper surface of the second bottom plate 501, the second fixing strip 502 is rotated back, the T-shaped sliding block 507 is loosened, the fixing clamp edge 5021 is fixedly inserted into the fixing groove 5071, the NHN insulating paper is tightly pressed through the elastic fixing strip 508, the NHN insulating paper to be detected is clamped and installed through the clamp 5, the NHN insulating paper is placed on the lower detection plate 4 through the clamp 5, the lower surface of the NHN insulating paper is tightly attached to the lower surface of the lower detection plate 4, the driving motor 13 is controlled to rotate, the driving motor 13 enables the upper detection plate 6 to downwards move through the lifting mechanism 14, the lower surface of the upper detection plate 6 is tightly attached to the upper surface of the NHN insulating paper, the heating plate 10 is used for heating, the temperature sensor 9 detects the temperature in the shell 1 and displays through the display 11, if the temperature is too high and the NHN insulating paper fails, the first contact 7 and the second contact 8 are conducted, the indicator lamp 12 is made to emit light, the temperature in the shell 1 is recorded, and the heat resistance of the NHN insulating paper is detected. .

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
