[0003] After retrieval, the application number is "202221298231.1", which provides a steel structure weld detector. One hand holds the main body of the detector, and the other hand holds the holding frame through the anti-slip sleeve. The sliding rod is pulled by the handle to compress the compression spring, so that the detection head is separated from the support pad. The detection head and the support pad are inserted into the weld, and the handle is released. The compression spring presses the detection head against the weld through the elastic force. The information collected by the detection head is transmitted to the main body of the detector for display through the data cable.
