[0002] When testing the depth of cracks on the exterior walls of buildings, a comprehensive crack detector is usually used. The principle of the comprehensive crack detector is mainly based on the principle of sound wave diffraction, which is a non-destructive testing technology used to measure the depth of concrete cracks and the propagation speed of ultrasonic waves in concrete. The comprehensive crack detector usually includes a crack tester host and a shell that is sleeved on the outside of the crack tester host, as well as two signal lines of several lengths and a planar transducer connected to the signal line. The ends of the two planar transducers are abutted against the detection points on the exterior wall, and the detection data is transmitted to the crack tester host to detect the depth of the cracks.

[0003] When using a comprehensive crack detector to detect the depth of cracks on the exterior walls of buildings, first use a ruler and a marker to mark multiple suitable detection points on the cracks of the exterior wall, then connect two signal lines to the crack tester host, and then connect two planar transducers to the other end of the signal line. Next, one end of the comprehensive crack detector is connected to the user's neck through a neck strap, and the other end is connected to the user's waist through a waist belt. Finally, hold the planar transducers in both hands and place them on the previously marked detection points to effectively detect the depth of the cracks.

[0004] In the above operation, the waist belt and the shell of the comprehensive crack detector are fixed, and cannot be conveniently and quickly detachably connected according to the needs of use, which reduces the flexibility of the device during use; and the signal line cannot be effectively stored during the detection process, which easily makes the signal line cluttered.
