A bolt 5 is mounted on one side of each connecting plate 4, allowing the connecting plate 4 to be movably connected to the outer triangular leg 3 via the bolt 5. A telescopic leg 10 is positioned below each outer triangular leg 3. The telescopic leg 10 is slidably connected to the corresponding outer triangular leg 3. Several threaded holes 6 are opened on the wall surface of the telescopic leg 10. A bolt 5 is provided on one side of the outer triangular leg 3. The bolt 5 is threadedly connected to the threaded hole 6. A first central rod 8 is fixedly provided on the bottom surface of the horizontal plate 1. A second central rod 9 is provided on the bottom surface of the first central rod 8. The second central rod 9 is slidably connected to the cavity of the first central rod 8. Several threaded holes 6 are opened on the wall surface of the second central rod 9. A bolt 5 is provided on the wall surface of the first central rod 8. The bolt 5 is threadedly connected to the threaded hole 6 on the wall surface of the second central rod 9. One end of the second central rod 9 is fixedly connected to the top surface of the square box 7.

[0027] Loosen the bolts 5 on one side of the outer triangular leg 3, adjust the telescopic leg 10 to a suitable height, and then tighten the bolts 5. Loosen the bolts 5 on one side of all connecting plates 4, adjust each outer triangular leg 3 to a suitable angle, and then tighten the bolts 5 to keep the outer triangular leg 3 and the telescopic leg 10 stable with the ground, forming the first layer of stable triangular structure. Loosen the bolts 5 on the outer wall of the first center rod 8 and adjust the length of the second center rod 9.

[0028] A support device for a 3D laser scanner used in surveying, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an inner triangular support structure is located below a horizontal plate 1. Three deployable stabilizing legs 11 are positioned below the horizontal plate 1. A lifting rod 16 is located in the middle of each stabilizing leg 11. A lead screw 13 is located on the top surface of the lifting rod 16, which drives the lifting rod 16 into the ground as the stabilizing legs 11 deploy. The inner triangular support structure also includes a worm gear 15, a turbine 19, and a transmission groove 20. A transmission groove 20 is formed on the top of each of the three stabilizing legs 11, and a turbine 19 is installed inside each transmission groove 20. Each turbine 19 is fixedly connected to both sides of the corresponding transmission groove 20. Next, three turbines 19 are driven and meshed with one worm gear 15. The inner triangular support structure also includes a rotating block 14. The bottom surface of the rotating block 14 is fixedly connected to the top surface of the worm gear 15. The lead screw 13 passes through the middle of the rotating block 14 and the worm gear 15 and is threadedly connected to the rotating block 14 and the worm gear 15. The triangular support structure also includes a square box 7, a stabilizing leg 11 and a side groove 12. A side groove 12 is opened on each side of the square box 7. The two ends of the stabilizing leg 11 are slidably connected to a side groove 12. The top end of the lead screw 13 is rotatably connected to the bottom surface of the stabilizing leg 11. The rotating block 14 passes through the bottom surface of the square box 7 and is rotatably connected to the square box 7.

[0029] Rotating the rotating block 14 causes the worm gear 15 to rotate, and each of the three turbines 19 drives a stabilizing leg 11 to rotate. The bottom of the stabilizing leg 11 is square, and the square bottom surface is in contact with the ground to maintain stability, forming a second layer of internal triangular stabilizing structure. The two layers of triangular stabilization can ensure that the device is more stable. Each stabilizing leg 11 is set between every two telescopic legs 10. While the rotating block 14 and the worm gear 15 are rotating, the lead screw 13 drives the lifting rod 16 to descend. The end of the lifting rod 16 rotates and inserts into the sand and gravel ground of the construction site to nail the device to the ground, which can effectively prevent the wind from blowing the device over and keep the 3D laser scanner stable.

[0030] A support device for a 3D laser scanner used in surveying, such as Figure 3 and Figure 4 As shown, the inner triangular support structure also includes a cone block 17 and a support rod 21. The top end of the lifting rod 16 is fixedly connected to the bottom end of the lead screw 13. The bottom end of the lifting rod 16 is a cone. Several cone blocks 17 are fixedly connected to the wall of the cone. Each stable leg 11 has a support rod 21 on each side and is rotatably connected to the support rod 21. The top surface of each support rod 21 is fixedly connected to the bottom surface of the square box 7.

[0031] The cone 17 rotates as it enters the gravel ground, which can quickly break the soil and allow the lifting rod 16 to enter the soil layer more quickly.

[0032] The working principle of this utility model is as follows: Loosen the bolts 5 on one side of the outer triangular leg 3, adjust the telescopic leg 10 to a suitable height, and then tighten the bolts 5. Loosen the bolts 5 on one side of all connecting plates 4, adjust each outer triangular leg 3 to a suitable angle, and then tighten the bolts 5 to keep the outer triangular leg 3 and the telescopic leg 10 stable with the ground, forming the first layer of stable triangular structure. Loosen the bolts 5 on the outer wall of the first central rod 8, adjust the length of the second central rod 9, rotate the rotating block 14, the rotating block 14 drives the worm gear 15 to rotate, and each of the three worm gears 19 drives one stable leg 11 to rotate. The device is square, with its bottom surface in contact with the ground for stability, forming a second layer of internal triangular stabilizing structure. The two layers of triangular stabilizing structure ensure greater stability of the device. Each stabilizing leg 11 is positioned between every two telescopic legs 10. As the rotating block 14 and worm gear 15 rotate, the lead screw 13 drives the lifting rod 16 to descend. The end of the lifting rod 16 rotates and inserts into the sand and gravel ground of the construction site, nailing the device to the ground. This effectively prevents the device from being blown over by the wind and keeps the 3D laser scanner stable. The cone block 17 enters the sand and gravel ground and rotates, which can quickly break the soil and allow the lifting rod 16 to enter the soil layer more quickly.
