[0021] Preferably, a group of tightening components 2 are fixedly installed on the workbench 1, and the interior of the tightening component 2 includes a mounting plate 210, an electric push rod 211 and a push plate 212. The mounting plate 210 is fixedly connected to the upper end of the workbench 1, and a group of electric push rods 211 are fixedly installed on the mounting plate 210. The output shaft of the electric push rod 211 is fixedly connected to one side of the push plate 212. The middle and lower position of the push plate 212 is slidably connected in the slide groove 113, and the slide groove 113 is fixedly opened in the workbench 1. The workbench 1 is located between the mounting plate 210 and the detection table 114. A group of heat dissipation components 4 are fixedly installed in the middle and lower position of one side of the push plate 212. The second airbag 410 and the connecting pipe 4 in the heat dissipation component 4 11. A second air inlet valve 412 and a second spring 413. The second air bag 410 is fixedly installed at the middle and lower position on one side of the push plate 212 and is located below the soot blowing assembly 3. Two groups of second springs 413 are fixedly installed inside the second air bag 410. A group of second air inlet valves 412 is fixedly installed on the upper end of the second air bag 410. The lower end of the second air bag 410 is fixedly connected to one end of a connecting pipe 411. The other end of the connecting pipe 411 is fixedly connected to the lower end of a ventilation pipe 117. The ventilation pipe 117 is fixedly opened inside the detection table 114. The upper end of the ventilation pipe 117 is located directly below the storage circuit board 115. The storage circuit board 115 is placed on the detection table 114.

[0022] (1) In the present invention, when the push plate 212 moves to a pre-set position, the outer surface of the first airbag 310 squeezes one side of the storage circuit board 115, while the other side of the storage circuit board 115 is pressed against the storage circuit board 115.

The external gas will enter the second airbag 410 along the second air inlet valve 412, and enter the first airbag 310 along the first air inlet valve 312 to complete the inflation for the next use.

[0024] Working principle: First, the two ends of the storage circuit board 115 correspond to the two sets of abutting grooves 116 on the detection table 114 respectively. After the storage circuit board 115 is placed, the mounting plate 210 is started. At this time, the mounting plate 210 will drive the push plate 212 to move forward. When it moves to the pre-set position, the outer surface of the first air bag 310 will squeeze one side of the storage circuit board 115, and the other side of the storage circuit board 115 will be pressed against the storage circuit board 115. While fixing the storage circuit board 115, the gas inside the first air bag 310 is squeezed and enters the second air outlet pipe 314 through the first air outlet pipe 313 and the shrink hose, and finally blown out from the air outlet to blow away the dust on the storage circuit board 115 to prevent it from affecting the detection result during detection. At the same time, the second air bag 410 will also be against the side wall of the detection table 114 The gas in the second airbag 410 will be squeezed against each other, and will be transmitted to the interior of the ventilation duct 117 through the connecting tube 411, and finally blown to the storage circuit board 115, which can effectively dissipate the heat of the storage circuit board 115 and prevent its own temperature from being too high and affecting the detection result. At this time, the detector 111 starts to detect the performance of the storage circuit board 115, and transmits the detection result to the central control system (not shown). After the detection is completed, the electric push rod 211 drives the push plate 212 to reset. At this time, the first airbag 310 and the second airbag 410 will no longer be squeezed, the first spring 311 drives the first airbag 310 to reset, and the second spring 413 drives the second airbag 410 to reset. The external gas will enter the interior of the second airbag 410 along the second air inlet valve 412, and enter the interior of the first airbag 310 along the first air inlet valve 312 to complete the inflation for the next use.
