[0032] Example:

[0033] See also Figure 1-7 A surveying and mapping geographic information data collection device includes a tripod 1 and a base 16, a fixing plate 11 is fixedly connected to the top of the tripod 1, a gear ring 12 is rotatably connected to the inside of the fixing plate 11, a gear 15 is rotatably connected to the inside of the fixing plate 11, a rack 14 is meshed on one side of the gear 15, the rack 14 is slidably connected to the inside of the fixing plate 11, a plug-in block 13 is fixedly connected to the outside of the gear ring 12, a clamping block 192 is slidably connected to the outer wall of the fixing plate 11, a spring 191 is provided between the clamping block 192 and the fixing plate 11, and a handle 19 is fixedly connected to the top of the clamping block 192 3. The block 192 is clamped in the interior of the plug-in block 13. In this solution, if the user needs to move the plug-in block 13 to drive the gear ring 12 to rotate, the user can pull the handle 193 upward to disengage the block 192 from the interior of the plug-in block 13. Then the user can move the plug-in block 13 to drive the gear ring 12 to rotate in the interior of the fixed plate 11. When the gear ring 12 rotates, it will drive the gear 15 to rotate. The rotation of the gear ring 12 will drive the rack 14 to slide in the interior of the fixed plate 11. The rack 14 slides in the interior of the fixed plate 11, so that one end of the rack 14 is clamped in the interior of the square groove 161.

[0034] See also Figure 1-7 A square groove 161 is provided at the bottom of the base 16 , and one end of the rack 14 is clamped inside the square groove 161 . In this solution, the square groove 161 is used to clamp one end of the rack 14 .

[0035] See also Figure 1-7 A worm gear 17 is fixedly connected to the top of the base 16, and a swivel 2 is fixedly connected to both sides of the worm gear 17. A rotating plate 18 is slidably connected to the top of the two swivels 2. In this solution, the rotating plate 18 moves along the outer wall of the swivel 2.

[0036] See also Figure 1-7The rotating plate 18 is internally rotatably connected to a worm 19, which is meshed with the worm wheel 17. One end of the worm 19 is fixedly connected to a turning handle 22. In this embodiment, when the user turns the turning handle 22, the worm 19 is driven to rotate. Since the worm wheel 17 cannot rotate, the rotating plate 18 is driven to slide along the outer wall of the rotating ring 2 when the worm 19 rotates.

[0037] See also Figure 1-7 A limit block 21 is fixedly connected to the bottom of the rotating plate 18, and the limit block 21 is slidably connected to the rotating ring 2. In this solution, the limit block 21 limits the rotating plate 18 and the rotating ring 2 to prevent the rotating plate 18 from falling off the outer wall of the rotating ring 2.

[0038] See also Figure 1-7 A surveying and mapping instrument body 23 is fixedly connected to the top of the rotating plate 18. In this solution, the surveying and mapping instrument body 23 is used to collect geographic information.

[0039] Working principle: after the user places the tripod 1 at the desired position, if the user needs to adjust the elevation angle of the surveying instrument body 23, the user can turn the handle 22. When the user turns the handle 22, the worm 19 will be driven to rotate. Because the worm wheel 17 cannot rotate, when the worm 19 rotates, it will drive the rotating plate 18 to slide along the outer wall of the rotating ring 2, thereby achieving the purpose of adjusting the elevation angle of the surveying instrument body 23. After the geographic information surveying and mapping is completed, when the surveying instrument body 23 needs to be disassembled and assembled, if the user needs to dial the plug-in block 13 to drive the gear ring 12 to rotate, the user can pull the handle 193 upwards to disengage the block 192 from the inside of the plug-in block 13, and then the user can dial the plug-in block 13 to drive the gear ring 12 to rotate inside the fixed plate 11. When the gear ring 12 rotates, it will drive the gear 15 to rotate. The rotation of the gear ring 12 will drive the rack 14 to slide inside the fixed plate 11. The rack 14 slides inside the fixed plate 11 When the gear ring 12 rotates counterclockwise, the rack 14 will be disengaged from the inside of the square groove 161. When the gear ring 12 rotates counterclockwise, one end of the rack 14 will move toward the center of the fixed plate 11. Because the plug-in block 13 and the card block 192 are both chamfered, when the gear ring 12 rotates clockwise, the chamfered portion of the plug-in block 13 will squeeze the chamfered portion of the card block 192, and the card block 192 will be pressed. After being squeezed, it will slide upward. When the block 192 slides upward, the spring 191 will undergo elastic deformation and contraction and store a certain amount of elastic potential energy. When the plug-in block 13 moves to the bottom of the block 192, the spring 191 in the elastic deformation state rebounds, thereby driving the block 192 to be clamped inside the plug-in block 13, thereby limiting the position between the gear ring 12 and the fixed plate 11, preventing the gear ring 12 from being deflected by external force and causing the rack 14 to be loosened in the square groove 161.

[0040] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improved concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
