The number of extension rods 3 is at least two, and the number of extension rods 3 can be increased according to the actual length. A connecting shaft 1 is installed at one end of the extension rod 3, and the other end of the extension rod 3 is provided with a thread groove 1 that matches the size of the connecting shaft 1. One end of the metal rod with the smallest diameter of the telescopic rod 1 4 is provided with a thread groove 2 that matches the size of the connecting shaft 1. The connecting shaft 1 at one end of an extension rod 3 is threadedly connected to the thread groove 2, and the connecting shaft at one end of the other extension rod 3 is threadedly connected to the thread groove 1 at the other end of the adjacent extension rod 3. The clamping assembly includes a mounting seat 1, a limit spring 12, a slider 13 and a clamping block 14. A connecting shaft 2 is installed at one end of the mounting seat 1, and the mounting seat 1 is connected to a portion away from the telescopic rod 1 4. The threaded groove of the extension rod 3 is threadedly connected, and a groove is provided at the other end of the mounting seat 1. The top and bottom of the groove are elastically connected to a slider 13 through a limit spring 12. A clamping block 14 is hinged at one end of the slider 13. When the slider 13 is perpendicular to the clamping block 14, the clamping block 14 is located inside the groove, and there is a gap between the two clamping blocks 14 for the operator to put in the finger. When the clamping block 14 is parallel to the slider 13, the part of the groove is extended out. The sides of the clamping blocks 14 that are close to each other are provided with anti-skid convex strips, which are squeezed and contacted with the outer side of the three-dimensional scanner body 2. The friction resistance between the clamping block 14 and the three-dimensional scanner body 2 is increased by the anti-skid convex strips, so as to achieve the clamping and fixation of the three-dimensional scanner body 2.

The inner side of the support rod 8 is hinged to the bottom end of the metal rod with the maximum diameter of the telescopic rod 2 6 through a limiting rod 9. The support rod 8 is limited by the sleeve 7 and the limiting rod 9. When the sleeve 7 is slid downward, the limiting rod 9 limits the support rod 8 to expand. When the sleeve 7 is slid upward, the limiting rod 9 limits the support rod 8 to be stored. A rotation groove matched with the size of the support rod 8 is provided at the lower end of the sleeve 7. The rotation groove provides a rotation space for the support rod 8. A storage groove matched with the size of the limiting rod 9 is provided on the inner side of the support rod 8. When the support rod 8 is stored, the limiting rod 9 is located inside the storage groove. A connecting block 10 is hinged at the bottom of the support rod 8.

A spike is provided at the bottom of the positioning rod 11.A handle is provided at the top of the positioning rod 11. The spikes reduce the resistance of the positioning rod 11 when inserted into the soil, and the threads on the surface of the positioning rod 11 increase the friction resistance between the positioning rod 11 and the soil, thereby improving the stability of the supporting device.

[0019] Working principle: When performing three-dimensional scanning, the operator stretches and unfolds the telescopic rod 1 4 and the telescopic rod 2 6, and then slides the sleeve 7 downward. The support rod 8 is limited and unfolded by the limit rod 9, and the connecting block 10 is fitted with the ground. The operator holds the handle on the top of the positioning rod 11 and rotates the positioning rod 11 to make the spikes at the bottom of the positioning rod 11 enter the soil and fix it, thereby increasing the overall stability. The extension rod 3 is then threadedly connected and fixed with the threaded groove 2 on the metal rod with the smallest diameter of the telescopic rod 1 4, and the connecting shaft 2 at one end of the mounting seat 1 is then connected and fixed with the threaded groove 1 of the extension rod 3. The operator inserts his finger into the groove at the other end of the mounting seat 1 and rotates the clamping block 14 to make the clamping block 14 extend out of the mounting seat 1 and connect with the mounting seat 1 is vertical, and the clamping block 14 is slid away from each other. Then the three-dimensional scanner body 2 stored separately is taken out and placed between the two clamping blocks 14. When sliding, the clamping block 14 drives the slider 13 to slide and squeezes the limit spring 12. After placement, the clamping block 14 is released, and the thrust of the limit spring 12 drives the slider 13 and the clamping block 14 to slide in the opposite direction. The clamping block 14 clamps and fixes the three-dimensional scanner body 2 through the anti-slip convex strip on one side, and the scanning work can be started. During the scanning operation, the personnel manually rotates the telescopic rod 4 away from the end of the extension rod 3, and drives the three-dimensional scanner body 2 to rotate together through the extension rod 3 and the clamping assembly, which effectively reduces the safety hazard caused by the operator being too close to the goaf.
