[0033] Among them, the limiting plate 4 is provided with an opening, and two openable and closable covers 11 are provided at the opening. When the two covers 11 close the opening, the lower surface of the cover 11 is flush with the lower surface of the limiting plate 4, and one of the loading mechanisms is located below the heating component.

[0034] In this technical solution, the heating component is used to heat the sample to be tested, the central axis of the disk 2 is arranged vertically, the horizontal rod 20 is arranged horizontally, the lifting rod is arranged vertically, the sample to be tested is placed on the stage 23, and the stage 23 is moved upward by adjusting the height of the lifting rod until the upper surface of the sample to be tested contacts the lower surface of the limit plate 4 (to determine whether the upper surface of the sample to be tested contacts the lower surface of the limit plate 4, the user can observe with his eyes or set a pressure sensor, a controller and an alarm on the stage 23. When the pressure sensor senses that the limit plate 4 squeezes the stage, the pressure sensor senses that the limit plate 4 squeezes the stage, and ... The force sensor transmits the sensed pressure signal to the controller, and the controller causes the alarm to sound a prompt). The number of the loading mechanisms is three or four. Under the rotation of the disc 2, when one of the loading platforms 23 is placing a sample, the loading platform 23 adjacent to the loading platform 23 is located under the heating component for detection. The samples to be tested on the remaining loading platforms 23 are cooled down. After the cooling is completed, the samples to be tested are separated from the loading platforms 23. One of the detachable connection methods between the support block 3 and the limit plate 4 can be a screw connection. The design of the loading platform 23 adopts the existing technology; the limit plate 4 is set horizontally.

The remaining load is cooled (after the cooling is completed, the sample to be tested is separated from the loading platform 23). For the loading mechanism for placing the sample to be tested: first place the sample to be tested on the loading platform 23, then connect the limit plate 4 with the support block 3, and then adjust the height of the loading platform 23 by the lifting rod until the upper surface of the sample to be tested is in contact with the lower surface of the limit plate 4 and the lower surface of the cover 11, and the placement of the sample to be tested is completed; after the testing of the loading mechanism located under the heating component is completed, rotate the disc 2 to make the loading mechanism after the testing be away from the heating component The component is cooled.

For the loading mechanism that has finished cooling: first close the cover body 11, then separate the limit plate 4 from the support block 3, take out the sample to be tested, if the same protective material needs to be placed, then place the sample to be tested directly on the stage 23 and connect the limit plate 4 to the support block 3. If a new sample to be tested of another thickness is replaced, first lower the stage 23 to the lowest position by adjusting the lifting rod, place the new sample to be tested on the stage 23, then connect the limit plate 4 to the support block 3, and finally adjust the height of the stage 23 by lifting and lowering.

This setting can effectively improve the detection efficiency, and at the same time, the loading mechanism is cooled before being removed, which can effectively avoid accidental injury to the user by the high temperature of the loading mechanism; the present invention sets an opening and a cover 11 on the limit plate 4. After the sample to be detected is placed on the stage 23, the disc 2 is rotated to move the stage 23 to the bottom of the heating component, and the cover 11 is opened for heating. This setting limits the height of the stage 23 (based on the thickness of the protective material) by the limit plate 4 on the one hand, and on the other hand, the cover 11 is not only convenient for heating the sample to be detected, but also can fix the sample to be detected by the cover 11 to avoid the movement of the sample to be detected during the rotation of the stage 23.
