[0026] When the device is used for temperature change test, after placing the object to be tested inside the test seat 5, the handle 12 can be pulled to slide the test seat 5 to adjust the electric heating plates 4 at different positions corresponding to it, and the internal space of the device can be divided by the positions corresponding to the two groups of electric heating plates 4. The heating effects of the two groups of electric heating plates 4 are different, and then the sliding position of the test seat 5 can be adjusted to correspond to the positions of the electric heating plates 4 at different positions, so that the temperature can be quickly changed through the different heating effects. When the test seat 5 slides in the two groups of test spaces, the insulation pad 9 can play a certain blocking role for the two groups of test spaces, and the test seat 5 can pass through the steering plate 7 when sliding, which can push the steering plate 7 to rotate, so that the metal plate 8 on its surface contacts the surface of the test seat 5, and then when it pushes the metal plate 8 and slides over, the metal plate 8 can play a proper heat absorption role on it, reduce the temperature in the test seat 5, and assist in cooling, so that it can carry out temperature difference change test work.

[0027] The inner bottom wall of the test seat 5 is fixedly installed with an operating table 13, the middle part of the top of the operating table 13 is embedded with a limit sleeve 14, the top of the limit sleeve 14 is plugged with a plug rod 15, the top of the plug rod 15 is fixedly installed with a placement seat 16, the outer surface of the placement seat 16 is threaded with two groups of symmetrically distributed control bolts 17, and the front end of the control bolt 17 is rotatably connected with a clamping plate 18;

[0036] The ventilation of the ventilation grid 23 ensures the normal operation of the heat dissipation fan assembly 24, which drives the circulation of air inside the test box 1, so that the heat inside the test box 1 can be output to achieve a cooling effect.

[0037] The front of the test box 1 is provided with two sets of movable doors 25, and both sides of the test box 1 are fitted with glass plates 26;

[0038] The movable door 25 is provided to facilitate the operation of the internal device of the device, and the device can be observed conveniently through the glass plate 26.

[0039] Working principle:

[0040] When the device is in use, after placing the object to be tested inside the placement seat 16, the test object can be clamped and positioned by the setting of the clamping structure inside the placement seat 16, and the position of the test seat 5 in the test box 1 can be slid and switched by pulling the handle 1 to correspond to different electric heating plates 4. Then, through the different heating effects and the setting of the heat dissipation structure in the test box 1, the test object can be tested for rapid temperature changes as the placement seat 16 moves.
