[0030] Working principle:

[0031] Step one, when the user needs to measure the crack, first twist the first cross slot block 4 according to the measurement environment, drive the first bidirectional threaded rod 3 through the first cross slot block 4, and then change the orientation of the first measuring ruler 8 by driving the first support 7 through the first bidirectional threaded rod 3, when the first measuring ruler 8 is rotated to the specified position, the user rotates the first limiting clamp block 6 through the rotating shaft, and makes one end of the first limiting clamp block 6 form a plug-in connection with the inner wall of the first cross slot block 4, fixes the angle of the first measuring ruler 8, and drives the first motor 10 through the first control panel 2, the first motor 10 drives the first connecting threaded rotating shaft 9 to rotate in the interior of the first measuring ruler 8 through the first transmission belt 11, and the threads on the inner wall of the first connecting threaded rotating shaft 9 move on the surface of the first bidirectional threaded rod 3, thereby measuring the width of the crack, this design can flexibly adjust according to the width and position of different cracks by adjusting the angle of the first measuring ruler 8, and ensures the accuracy of the measurement.

[0032] Step two, when the user forms a plug-in connection between the first limiting clamp block 6 and the first cross slot block 4 through the rotating shaft, moves the first limiting clamp plate 12 along the inner wall of the first transmission belt 11, limits the first limiting clamp block 6, prevents it from unfolding, and makes the plug-in connection between the first limiting clamp block 6 and the first cross slot block 4 more firm, when moving the first limiting clamp plate 12, the user slides the first circular groove 13 on the surface of the first sliding rod 14, and the first sliding rod 14 ensures the stability of the movement of the inner wall of the first limiting clamp plate 12, when the user needs to remove the limitation on the first limiting clamp block 6, moves the first limiting clamp plate 12 along the inner wall of the first transmission belt 11, at this time, the first limiting clamp plate 12 extrudes the first spring 15, and makes it store energy and compress, when the user needs to restore the limitation on the first limiting clamp block 6, releases the first limiting clamp plate 12, the first spring 15 releases and rebounds, and pushes the first limiting clamp plate 12 to automatically return to the original position.

[0033] Step three, when the user drives the first motor 10 through the first control panel 2, the first motor 10 drives the first measuring ruler 8 to move along the thread on the surface of the first bidirectional screw rod 3, and the first measuring ruler 8 slides smoothly on the surface of the first limiting rod 17 through the first sliding groove 16, which ensures that the movement is more stable. When the user does not use the device temporarily, turn the first cross-shaped block 4 to make the first measuring ruler 8 enter the first storage slot 18, then turn the first protective cover plate 19 through the rotating shaft, and insert the pins at both ends of the first protective cover plate 19 into the pin slots on one side of the first shell 1 to fix the position of the first protective cover plate 19. By storing the first measuring ruler 8, the overall size of the device is reduced, which is convenient for carrying and storing, and the risk of accidental injury caused by exposed parts is also reduced. After the first measuring ruler 8 is stored in the first storage slot 18, the first protective pad 20 can avoid direct friction with the inner wall of the storage slot, reducing the wear on the surface of the first measuring ruler 8.
