[0018] When in use, the operator holds the handle 2, then fits the device on the end face of the sampling position, and then inputs a signal to the control module through the control button 3. At this time, the electric push rod 18 will push the connecting rod 20 toward the sampling chamber 10. At this time, the scraper 13 will scrape the metal corrosion sample and leave it in the sampling chamber 10. Then the operator can lift the device to transfer the sample; in this process, the operator can observe the sampling situation through the observation window 4 to ensure the progress of the sampling work.

The connecting tube 6 is detachably connected to the mounting block 7 by bolts. A rotating handle 5 is provided on the upper part of the connecting tube 6.

[0021] When in use, the control unit 3 can be used to energize the electromagnet 17 to generate magnetic force, so that the device is attached to the sampling position and fixed, so that the device remains stable during the sampling process; when encountering tubular materials, the corresponding accessories can be fixed by the buckle 9, and then the height of the clamping rod 8 can be adjusted by rotating the handle 5 to adapt to the fixation of the pipe. After the height probe 12 is completely in contact with the sampling metal surface, the sensing module will send a signal to the control module and display the light to inform the operator that the device has been in contact with the material surface and sampling can be carried out.
