When the buttons on the detector need to be operated, the detection probe needs to be placed on the ground before operation, which is inconvenient for users to operate and view the detector.

[0003] Existing crack detection devices for construction projects cannot fix the detection probe for installation, and cannot rotate and adjust the orientation angle of the display screen during use, which is inconvenient for users to observe the detection data in time. Traditional detectors require users to frequently check the head of the device, which can easily cause neck pain in the long run and consume a lot of physical strength of the user. The connecting wires between the detection probe and the detector are scattered and easily tangled, which interferes with the normal progress of crack detection and affects the progress of crack detection. It is impossible to achieve different combination use functions of the detection device by changing the installation order between the structures. Summary of the invention
