At the same time, it can be adjusted according to steel plates 202 of different sizes, so that the device can adapt to the fixing needs of various specifications, increasing the versatility and application range of the device. When the detection is completed, the baffle 207 can be opened to directly push out the steel plate 202, without the need for disassembly, improving the overall efficiency of detection and facilitating subsequent detection work, which is conducive to the rapid turnover of the detection process.
