[0015] 1. This adjustable crack detection device for water conservancy testing uses a fixed plate that moves downwards to move a movable plate downwards. Then, rotating the fixed pin clockwise to press the movable plate against the movable plate causes the movable frame to move downwards, which in turn moves the movable bracket downwards. This makes it easier for operators to adjust the position of the components inside the device according to the crack depth, shortens the time required for operators to adjust the position of the components inside the device, and further improves the work efficiency of operators in adjusting the position of the components inside the device.

[0016] 2. This adjustable crack detection device for water conservancy testing moves the protective plate inward, causing the connecting plate to move inward as well. This allows the protective rod to move inward along the moving frame, and then the connecting plate moves inward to compress the protective spring. This makes it easier for operators to manipulate the internal components of the device to protect the equipment, preventing the equipment from impacting cracks during the operation of the internal components. This reduces the impact on the operator's normal crack detection and further enhances the effectiveness of the internal components during operation.

[0017] 3. This adjustable crack detection device for water conservancy testing, by inserting a fixing pin into the connecting frame and then rotating the fixing pin clockwise to press against the moving plate, makes the internal components of the device more stable during use, thereby preventing the components from loosening during use, further improving the stability of the internal components during use, reducing the impact of loose components on the normal use of the device, and making it easier for operators to operate the components to fix the device.
