In this embodiment, the outer diameter of the above-mentioned plug column 18 is smaller than the outer diameter of the plug rod 10, and the plug column 18 is a solid rod. The end of the plug column 18 away from the fixing sleeve 17 is also pointed, so as to facilitate insertion into the ground for fixation.

[0028] In some application scenarios of this embodiment, after determining the monitoring point, use a soil drill to drill a hole slightly smaller than the outer diameter of the plug rod 10 at the installation point, with a depth of 300-400 mm, and then insert the plug rod 10 into the hole, and then adjust the height of the fixing sleeve 17, insert the three plug posts 18, and fix the plug posts 18 for a second time through the adjustment handle of the plug rod 10. After the plug rod 10 is installed, insert the adjustment sleeve 11 and the adjustment bracket 12, confirm the installation position of the crack meter wire rope 32, and fix the adjustment bracket 12 through the first fastener 21 and the second fastener 22. Finally, fix the PVC pipe on the PVC pipe clamp 14 of the adjustment bracket 12, and fix the crack meter wire rope 32 on the hook 13 of the adjustment bracket 12, and the installation is completed. When removing, just loosen the hand screw (third fastener 23) on the fixing sleeve 17 and pull out the plug rod 10, so as to achieve quick installation, ready to use, and reusable effect.

[0029] In summary, the crack meter fixing bracket in the above-mentioned embodiment of the utility model is provided with an insertion rod 10, and an adjusting bracket 12 is provided on the insertion rod 10. When fixing, the insertion rod 10 is fixed to the soil. The adjusting bracket 12 is provided with a hook 13 for connecting the crack meter wire rope 32, and a pipe clamp 14 for clamping the protection tube 31.
