The height between the two ends is determined by the height position. After confirming the height position, the telescopic rod 1 is retracted and fixed by tightening the first fixing screw 11. The displacement meter is placed on the suction cup 17, and the displacement meter is fixed by the suction cup 17. The displacement of the anchor rod can be effectively measured through the bracket. The telescopic legs 12 are retracted and extended so that the bracket can be placed on the sloping ground. It can be quickly adjusted during use, and multiple sets of telescopic legs 12 can be retracted to different lengths and placed on the ground to stabilize the bracket, thereby reducing the tilt of the bracket on uneven ground. Reducing the tilt of the bracket can make the measurement data more accurate. The fixed plate 14 can be rotated to effectively adapt to different angles of the ground, and the bracket can be retracted and placed when not in use to effectively save storage space. The cone 15 can better combine with the soil, effectively increasing the stability of the bracket position, thereby effectively improving work efficiency and measurement accuracy.
[0026] like Figure 1 As shown, the side walls of the two fixed plates 14 close to each other are fixed with elastic cloth 2, and the middle part of the elastic cloth 2 is fixed with multiple groups of support blocks 21, and the support blocks 21 are evenly distributed in the middle part of the elastic cloth 2. When working, multiple groups of cones 15 enter the ground, and the elastic cloth 2 connected to each other through the side walls of the fixed plates 14 fits with the ground, and contacts with the ground through multiple groups of support blocks 21. The elastic cloth 2 can increase additional stabilizing force for the bracket. When the bracket is vibrated or collided with external force, the elastic cloth 2 increases the buffering effect, effectively reducing the shaking of the bracket, and the support blocks 21 can increase the fit with the ground, effectively reducing the tilt or displacement of the bracket caused by the uneven ground.

During operation, after the measurement is completed, the telescopic leg 12 is retracted, and the connecting plate 6 is fixed to the sliding part so that the bristles 61 clean the surface of the telescopic leg 12 when it is retracted. The bristles 61 can effectively reduce the dirt on the ground remaining on the surface of the telescopic leg 12 after measurement, and reduce the accumulation of surface dirt remaining on the telescopic leg 12 when the telescopic leg 12 is retracted, effectively reduce the accumulation of internal dirt causing telescopic jamming, and reduce the accumulation of dust inside the telescopic leg 12, which can effectively reduce the damage to the interior caused by a long time, and can effectively reduce the difficulty in maintenance and cleaning.

After confirming the height position, the telescopic rod 1 is extended and fixed by tightening the first fixing screws 11, and the displacement meter is placed on the suction cup 17, and the displacement meter is sucked and fixed by the suction cup 17. Multiple groups of cones 15 enter the ground, and the elastic cloth 2 connected to each other through the side walls of the fixing plate 14 is in contact with the ground, and the multiple groups of support blocks 21 are in contact with the ground, and the pressure column 33 is fixed in the groove 3 through the support rods 36 on both sides, and the pressure column 33 is pressed to make the support rods 36 on both sides slide in the slide groove 34, and the expansion plug 31 is entered through the pressure column 33, and the expansion plug 31 is squeezed at the same time by the pressure column 33 moving downward. On the side, when the expansion bolt 31 expands outward, the fixed column 32 moves to the outside of the cone 15 through the through hole 37. When the pressure column 33 is pulled out of the groove 3, the expansion bolt 31 rebounds inward to make the fixed column 32 return to the cone 15 through the through hole 37. After the displacement meter is placed on the suction cup 17, the two elastic bands 4 are stretched to make the middle part of the elastic band 4 fit with the displacement meter, and the sub-buckle 41 is inserted from the top of the mother buckle 42 to fix the elastic band 4 from one end to the other. After the telescopic rod 1 is placed, the cone block 52 can remain perpendicular to the ground through the fixing rope 51 connected to the bottom of the support plate 5 after the bracket is placed. After the cone block 52 is stationary, it is observed in front of the angle plate 53 whether the bracket is perpendicular to the ground. After the measurement is completed, the telescopic leg 12 is retracted. It is fixed at the sliding position through the connecting plate 6 so that the bristles 61 clean the surface of the telescopic leg 12 when it is retracted. When the elastic band 4 fits and fixes the displacement meter, it fits with the surface of the displacement meter through the sponge pad 7.
