A second spring 53 is fixedly connected to the right side of the positioning plate 52. The right side of the second spring 53 is fixedly connected to the inner wall of the groove 3.

[0030] By adopting the above solution, the positioning component 5 is designed so that the positioning rod 51 and the positioning plate 52 work together with the elastic action of the second spring 53 to ensure the accurate positioning of the crack detector 24 on the mounting block 21 and prevent detection errors caused by positional offset.

[0031] refer to Figure 4 The bottom of the extrusion rod 41 is provided with an inclined plate 6, and a toothed plate 7 is fixedly connected to the right side of the inclined plate 6. A gear 8 is meshed on the surface of the toothed plate 7, and a fixed rod 9 is rotatably connected to the rear side of the gear 8.

[0039] The working principle of this utility model:

[0040] When using the device;

[0041] By having the user wear the belt 1 around their waist, it is ensured that the belt 1 is secure and comfortable;

[0042] Then the extrusion assembly 4 starts working. When the extrusion rod 41 is subjected to external force, such as manual pressing by the user, it drives the extrusion plate 42 to move downward. The extrusion plate 42, through the action of the vertical rod 43 and the first spring 44, applies pressure to the extrusion assembly 4. At the same time, the positioning assembly 5 starts working. When the positioning rod 51 is subjected to the extrusion force of the inclined plate 6 by the extrusion rod 41, the inclined plate 6 can drive the gear 8 to rotate through the toothed plate 7. Through the rotation of the gear 8, the positioning rod 51 and the teeth 10 set at the bottom of the positioning plate 52 can mesh and move. Thus, after the positioning rod 51 is rotated by the gear 8, it will move to the right and penetrate to the right side of the groove 3. At the same time, the positioning plate 52 maintains a certain tension through the action of the second spring 53. Then, the worker connects the positioning block 23 with the mounting groove 22. After the connection is completed, the worker releases the extrusion rod 41. The positioning rod 51 will be released by the tension of the second spring 53 and enter the surface of the positioning groove 13 to fix the positioning block 23.

[0043] In summary, this intelligent crack detection device for roads and bridges addresses the problem that traditional crack detection tools are often bulky, difficult to carry, and complex to operate. This device, through its belt design, achieves portability, allowing staff to easily wear it and conduct on-site inspections.
