[0002] Chinese patent application number 202221756737.2 discloses an adjustable surveying and mapping stand, which drives the support legs to fold or unfold by moving the guide ring up and down and cooperating with the connecting rod, and indirectly drives the telescopic frame to move up and down by rotating the handle, thereby realizing the extension or contraction of the telescopic frame. When the surveying and mapping stand is not needed, the telescopic frame is moved to the inside of the storage cavity, and the support legs are folded and moved inside the storage cavity. The support legs are adsorbed and fixed by the attraction of the first permanent magnet and the second permanent magnet, so that the support legs are stored inside the storage cavity, thereby reducing the volume between the surveying and mapping stands, making it easier for users to carry, and the provision of a hand rope makes it easier for users to carry the surveying and mapping stand.

[0003] However, when the device is supporting, the surveying frame is supported only by the supporting legs, and the brackets and telescopic frames above the supporting legs are at a high height, resulting in poor support stability of the surveying frame as a whole; and although the existing surveying frame has a large support opening angle, when performing leveling adjustment, the user needs to observe the position of the circular level bubble while leaning over to adjust the locking knob of the supporting leg, resulting in the user being unable to adjust the telescopic length of the supporting leg while observing the circular level bubble, which is less practical.

[0026] The threaded adjustment block, buckle block strap 1, buckle block strap 2, insert block strap 1, insert block strap 2, circular level bubble, tripod centering screw and threaded rod in this case are existing technologies. The threaded adjustment block and threaded rod have the same structure and connection method as in the cited documents. As long as the threaded adjustment block, buckle block strap 1, buckle block strap 2, insert block strap 1, insert block strap 2, circular level bubble, tripod centering screw and threaded rod meet the requirements of this case, they can be used and are not limited to a single model.

[0027] Working principle: the electrical components appearing in this application are all externally connected to the power supply and control switch when in use. After the utility model is installed, first check the installation and fixation of the utility model as well as the safety protection, and then it can be used; when in use, the user carries the tripod 3 to the surveying and mapping site, and then the user presses to open the buckle block strap 11 and the plug block strap 1 13 as well as the buckle block strap 2 12 and the plug block strap 2 14. After loosening the tripod 3, the user turns the three knobs 1 9 to make the knob 1 9 drive the worm 83 to rotate, and the worm 83 engages the worm gear 82 to drive the threaded rod 81 to rotate, and the threaded rod 81 cooperates with the threaded adjustment block 10 to drive the telescopic frame 5 to slide in the sliding groove 4, thereby raising the height of the placement table 2, and the raised height can be roughly to the user's chest or shoulder height; then rotate the tripod externally Frame 32 rotates the rotating block 31 and the outer shell 1 to unfold the surveying frame. The center point of the surveying frame is set just above the center of the control point. When the surveying frame is placed stably, take out the surveying equipment and place it on the placement table 2. Tighten the tripod centering screw 16. After turning on the machine, turn on the laser to align with the control point. Then perform rough leveling. Observe the circular level bubble 15 during the adjustment process. Rough leveling is performed by moving the tripod 3 of the surveying frame. The side to which the circular level bubble 15 deviates indicates which side is higher. At this time, the height can be lowered by turning the knob 1 9 on the higher side for rough leveling. When the angle of the surveying equipment needs to be adjusted, the user drives the rotating shaft 20 to rotate by turning the knob 21. The rotating shaft 20 drives the gear 19 to rotate. The gear 19 engages with the outer gear ring 18 to drive the placement table 2 to rotate, thereby changing the angle of the surveying equipment.
