[0004] Existing vertical surveying devices rely on bolts and brackets to complete equipment assembly and ground support. The equipment body does not have a closed protective structure, and the surveying instruments are completely exposed during transportation, which can easily lead to damage to the parts. In addition, the equipment lacks dedicated storage space and operating table, reducing the overall practicality of field surveying operations. Summary of the Invention

[0005] The main objective of this invention is to provide a vertical surveying device for geographic mapping that is easy to fix, which can effectively solve the problems involved in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A vertical geographic surveying device that is easy to fix includes a base shell and a digital surveying instrument. The upper end of the base shell is provided with a surveying support structure for raising and lowering the digital surveying instrument. The digital surveying instrument is mounted on the upper side of the surveying support structure via a mounting base. The upper end of the base shell is symmetrically provided with protective housings for protecting the digital surveying instrument. Each of the two protective housings has an auxiliary storage box mounted on its upper end via a hinge. Both ends of the two auxiliary storage boxes are fixedly connected with locking buckles, and the two locking buckles on the same side are interlocked. The inner cavities of the two protective housings are symmetrically provided with support legs for fixing the relative position of the base shell.

[0008] Preferably, the auxiliary storage box includes a rectangular frame that is rotatably connected to the upper end of the protective box via a hinge. The rectangular frame is fixedly connected to a storage box for storing auxiliary tools. A cabinet door is rotatably installed on the upper part of the inner surface of the storage box via a hinge. A handle is fixedly connected to the upper end of the rectangular frame. The locking buckle is fixedly installed on the left and right sides of the rectangular frame.

[0009] Preferably, the auxiliary storage box further includes L-shaped guide grooves symmetrically opened on the inner wall of the rectangular frame, and the inner wall of the rectangular frame is provided with an extension table that is slidably connected to the inner surface of the two L-shaped guide grooves. The paths of the two L-shaped guide grooves are offset towards the direction of the digital surveying instrument.

[0010] Preferably, the extended table includes a micro motor symmetrically fixedly installed on the inner wall of a rectangular frame and L-shaped rods symmetrically slidably connected to the inner walls of the rectangular frame and adjacent L-shaped guide grooves. The lower ends of the two L-shaped rods are provided with sliding grooves communicating with the upper ends. The upper ends of the two L-shaped rods are jointly fixedly connected to a table board that is slidably connected to the inner surface of the rectangular frame. The output end of the micro motor is driven by a threaded rod through a coupling. The outer surfaces of the two threaded rods are respectively threaded with driven members that are slidably connected to the inner surfaces of adjacent sliding grooves. When the L-shaped rods move to the horizontal path range of the L-shaped guide grooves, they will drive the table board to move away from the L-shaped guide grooves and fit against the outer surface of the rectangular frame.

[0011] Preferably, the driven member includes a sliding plate that is slidably connected to the inner surface of the slide groove and threadedly connected to the outer surface of the threaded rod. The lower end of the sliding plate is symmetrically fixedly connected to a limit spring rod. The outer surfaces of the center rods of the two limit spring rods are slidably connected to a threaded slider that is slidably connected to the outer surface of the threaded rod. The threaded slider is slidably connected to the inner surface of the slide groove. When the threaded rod rotates, the sliding plate is positioned relative to the threaded rod under the limiting action of the slide groove. The sliding plate and the threaded slider drive the L-shaped rod to slide on the inner wall of the rectangular frame and the L-shaped guide groove, and simultaneously drive the table to move from the inside of the rectangular frame outward.

[0012] Preferably, the support leg includes a buffer spring rod fixedly connected to the upper end of the bottom shell via a connecting block. A rack two is slidably connected to the outer surface of the buffer spring rod via a spring. The upper end of the rack two is engaged with a gear rotatably connected to the inner wall of the protective box. A limit buckle is fixedly connected to the middle of the inner surface of the protective box. A sliding rod is slidably connected to the inner surface of the limit buckle. A rack one that meshes with the gear is fixedly connected to the side of the sliding rod away from the inner wall of the protective box. An anti-slip support leg is threaded to the lower end of the sliding rod. A through hole is provided on the bottom wall of the inner surface of the protective box for the sliding rod to pass through.

[0013] Preferably, the surveying support structure includes a support base fixedly installed on the upper end of the bottom shell. The inner surface of the support base is provided with a lifting base for driving the digital surveying instrument to rise and fall. Both ends of the lifting base are rotatably connected to connecting rods that are rotatably connected to the inner wall of the protective box. When the two protective boxes move away from each other, the connecting rods drive the lifting base to move upward.

[0014] Preferably, the support base includes a central block installed on the upper end of the bottom shell. A compression spring is slidably connected to the inner surface of the central block and fixedly connected to the lower end of the lifting base. A sliding block sleeved on the outer surface of the compression spring is fixedly connected to the inner cavity of the central block. The lower end of the compression spring extends through the central block into the inner cavity of the bottom shell and is fixedly connected to a cross spring plate slidably connected to the inner cavity of the bottom shell. The lower end of the cross spring plate is fixedly connected to a roller. When the compression spring is in the initial state, the roller is located at the lower end of the bottom shell. When the lifting base rises, the compression spring rises with the lifting base and drives the roller to retract into the inner cavity through the cross spring plate.

[0015] Preferably, the lifting base includes a T-shaped block slidably mounted on the inner surface of the central block and fixedly connected to the upper end of the connecting rod. An electric threaded ring driven by a motor is rotatably mounted on the upper end of the T-shaped block. A threaded rod 2, which is slidably connected to the inner surface of the electric threaded ring, is threadedly connected to the inner surface of the T-shaped block. The digital surveying instrument is mounted on the upper end of the threaded rod 2 via a quick-release base. Connecting grooves that are rotatably connected to the connecting rod are opened at both ends of the T-shaped block. When the electric threaded ring rotates, the threaded rod 2 moves upward or downward under the action of the thread.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention achieves the switching between vertically closed and horizontally unfolded states through the hinged connection between the auxiliary storage box and the protective box. The rectangular frame integrates storage boxes and cabinet doors to provide independent and safe storage space for surveying auxiliary tools. The handle facilitates the overall handling of the device, and the locking buckle can fix the transport state to prevent the protective box from being accidentally unfolded. The L-shaped guide groove, together with the follower and L-shaped rod, accurately guides the movement trajectory of the table. The limit spring rod buffers and limits the movement and compensates for processing errors. The extension table driven by the micro motor forms a flat and stable operating platform after unfolding, improving the overall convenience of surveying work.

[0018] 2. This invention utilizes a linkage design between the support legs and the protective housing. A transmission structure involving a buffer spring rod and a rack and pinion mechanism enables synchronized operation of the protective housing's unfolding and the support legs' automatic extension and retraction, eliminating the need for manual adjustment. The limit buckle guides and limits the sliding rod, ensuring smooth movement of the support legs. The anti-slip legs increase friction with the ground, enhancing the device's stability and preventing tilting or swaying during surveying. The buffer spring rod also absorbs unexpected vibrations, preventing them from being transmitted to the digital surveying instrument and affecting surveying accuracy.

[0019] 3. This invention utilizes the linkage design of the surveying support structure and the protective box. By means of a connecting rod, the horizontal movement of the protective box is converted into the vertical movement of the lifting base, realizing the synchronous operation of the unfolding and storage of the protective box and the lifting of the digital surveying instrument. There is no need to operate the lifting mechanism separately. The connecting groove of the T-shaped block ensures the stability of the connecting rod rotation connection. The sliding block plays a radial guiding role for the compression spring, ensuring the stability of the movement process. The cross spring plate links the roller to complete the extension and retraction action, while absorbing ground vibration and improving the shock resistance of the device. The bottom shell is in direct contact with the ground to enhance the placement stability. The electric threaded ring and the threaded rod work together to realize the fine adjustment of the working height of the digital surveying instrument. The quick-release base facilitates the quick installation, disassembly and model change of the digital surveying instrument. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1: A vertical geographic surveying device that is easy to fix, see [reference] Figure 1 and Figure 2 The device includes a base shell 1 and a digital surveying instrument 7. The base shell 1 serves as the basic load-bearing structure of the entire device, providing a foundation for the installation and support of all upper components. The upper end of the base shell 1 is equipped with a surveying support structure 6 for raising and lowering the digital surveying instrument 7. The surveying support structure 6 can drive the digital surveying instrument 7 to complete the raising and lowering action, and can also link the movement of the protective box 2 and the support legs 21 to realize the synchronous operation of the device's unfolding and folding. The digital surveying instrument 7 is installed on the upper side of the surveying support structure 6 through a mounting base. The digital surveying instrument 7 is the core surveying component of the device, used to collect geospatial data, and is a basic device used in the existing surveying and mapping technology field.

[0032] The bottom shell 1 has symmetrical protective housings 2 on the left and right sides to protect the digital surveyor 7. The protective housings 2 fit together in the transportation state and together with the auxiliary storage box 3 form a closed space to completely surround the digital surveyor 7, preventing the digital surveyor 7 from being damaged by collisions, vibrations or dust during transportation, and extending the service life of the digital surveyor 7. The auxiliary storage box 3 is mounted on the top of each of the two protective housings 2 by hinges. The auxiliary storage box 3 can be vertically closed on the top of the protective housing 2 in the transportation state, and can be horizontally unfolded to form a support platform in the use state. The front and rear ends of the two auxiliary storage boxes 3 are fixedly connected with locking buckles 4. The two locking buckles 4 on the same side are interlocked. The locking buckles 4 are interlocked in the transportation state to fix the two auxiliary storage boxes 3 as one, preventing the protective housings 2 from being accidentally unfolded and improving the safety of the device during transportation.

[0033] The inner cavities of the two protective boxes 2 are symmetrically equipped with support legs 21 for fixing the relative position of the bottom shell 1. The support legs 21 automatically extend and contact the ground when the device is unfolded, increasing the contact area between the device and the ground, improving the stability of the device and preventing the device from sliding during the surveying process.

[0034] In the operation of this example, the protective box 2 and the auxiliary storage box 3 are used together to form a closed space to protect the digital surveying instrument 7. The locking buckle 4 is used to fix the transport state to prevent the protective box 2 from being accidentally unfolded. The connecting rod 63 is used to link the protective box 2 and the surveying support structure 6 to realize the unfolding and the lifting and lowering of the digital surveying instrument 7 synchronously. With the help of the buffer spring rod 216, the rack 215, gear 214 and rack 213 drive the support leg 21 to automatically extend. This not only improves the safety of the device during transportation, but also simplifies the operation process, enhances the placement stability during surveying, and ensures the accuracy of the surveying data.

[0035] Example 2: Based on Example 1, this example uses a hinged connection between the auxiliary storage box 3 and the protective box 2 to switch between vertically closed and horizontally unfolded states. The rectangular frame 31 integrates a storage box 32 and a cabinet door 34 to provide an independent and safe storage space for surveying auxiliary tools. The handle 33 facilitates the overall transport of the device. The locking buckle 4 can fix the transport state to prevent the protective box 2 from being accidentally unfolded. The L-shaped guide groove 36, together with the follower 355 and the L-shaped rod 356, precisely guides the movement trajectory of the table 351. The limit spring rod 3552 buffers and limits the movement and compensates for processing errors. After unfolding, the extension table 35 driven by the micro motor 352 forms a flat and stable operating platform, improving the overall convenience of surveying work.

[0036] For further details, please refer to [link / reference]. Figure 2 and Figure 3The auxiliary storage box 3 includes a rectangular frame 31 that is hinged to the upper end of the protective box 2. The rectangular frame 31 serves as the main frame of the auxiliary storage box 3 and is connected to the upper end of the protective box 2 via a hinge, allowing for switching between vertically closed and horizontally open states. A storage box 32 for storing auxiliary tools is fixedly connected to the rectangular frame 31. The storage box 32 is fixed inside the rectangular frame 31 and is used to store various surveying auxiliary tools, providing independent storage space for them. The upper part of the inner surface of the storage box 32 is hinged for rotation. Equipped with a cabinet door 34, which is closed during transport to prevent auxiliary equipment from falling off or being lost during transport. A handle 33 is fixedly connected to the upper end of the rectangular frame 31. When the device is in transport, the handle 33 can be used as a grip structure for overall handling, facilitating the overall transfer of the device. Locking buckles 4 are fixedly installed on the left and right sides of the rectangular frame 31. When two locking buckles 4 on the same side are engaged, they can securely connect the two auxiliary storage boxes 3, while limiting the relative position of the protective box 2, preventing the protective box 2 from being accidentally opened during transport.

[0037] For further details, please refer to [link / reference]. Figure 4 The auxiliary storage box 3 also includes L-shaped guide grooves 36 symmetrically opened on the inner wall of the rectangular frame 31. The L-shaped guide grooves 36 are used to restrict the movement trajectory of the extension table 35, prevent the extension table 35 from deviating or getting stuck during the sliding process, and ensure the smoothness of the extension table 35's unfolding and storage process. The inner wall of the rectangular frame 31 is provided with an extension table 35 that slides and connects to the inner surface of the L-shaped guide grooves 36 on both sides. The extension table 35 can complete the actions of storage and outward unfolding inside the rectangular frame 31. The paths of the two L-shaped guide grooves 36 are L-shaped, and the lower part of them is offset towards the direction of the digital surveying instrument 7. This special path design can guide the extension table 35 to adjust its position in the vertical direction first, and then slide smoothly out in the horizontal direction towards the direction of the digital surveying instrument 7, and finally fit tightly against the outer surface of the rectangular frame 31 to form a flat and stable operating platform.

[0038] For further details, please refer to [link / reference]. Figure 5The extendable table 35 includes micro motors 352 symmetrically fixed to the inner wall of a rectangular frame 31 and L-shaped rods 356 symmetrically slidably connected to the inner walls of the rectangular frame 31 and adjacent L-shaped guide grooves 36. The micro motors 352 provide power for the unfolding and folding of the extendable table 35. The L-shaped rods 356 serve as intermediate transmission components connecting the tabletop 351 and the driven member 355, converting the linear motion of the driven member 355 into the sliding motion of the tabletop 351. The lower ends of both L-shaped rods 356 are provided with sliding grooves 354 that communicate with the upper ends. The sliding grooves 354 provide sliding space for the driven member 355 and limit the direction of movement of the driven member 355. The upper ends of the two L-shaped rods 356 are fixedly connected to the tabletop 351, which is slidably connected to the inner surface of the rectangular frame 31. When folded, the tabletop 351 is completely located within the rectangular frame 31. The unit does not occupy extra space and forms a flat operating platform when unfolded, making it convenient for operators to place surveying and drawing tools or other auxiliary tools, avoiding the loss of tools or interference with surveying operations. The output end of the micro motor 352 is connected to the threaded rod 353 through a coupling. The coupling can transmit torque and compensate for the installation error between the micro motor 352 and the threaded rod 353, ensuring the stability of the transmission. The outer surfaces of the two threaded rods 353 are respectively threaded with driven members 355 that slide on the inner surface of the adjacent slide groove 354. The driven members 355 can convert the rotational motion of the threaded rods 353 into their own linear motion. When the L-shaped rod 356 moves into the horizontal path range of the L-shaped guide groove 36, it will drive the table 351 to move away from the L-shaped guide groove 36 and fit against the outer surface of the rectangular frame 31.

[0039] For further details, please refer to [link / reference]. Figure 6The driven member 355 includes a sliding plate 3551 that is slidably connected to the inner surface of the groove 354 and threadedly connected to the outer surface of the threaded rod 353. The sliding plate 3551 is the main transmission component of the driven member 355, which can convert the rotational motion of the threaded rod 353 into linear motion along the direction of the groove 354. The lower end of the sliding plate 3551 is symmetrically fixedly connected to limit spring rods 3552. The limit spring rods 3552 have a certain elastic extension capacity and can play a buffering and limiting role when the table 351 moves to the extreme position to prevent the micro motor 352 from being overloaded and damaged. At the same time, it can compensate for machining errors and ensure the fitting accuracy between the driven member 355 and the L-shaped rod 356. The outer surface of the center rod of the two limit spring rods 3552 is A threaded slider 3553 is slidably connected to the outer surface of the threaded rod 353. The threaded slider 3553 is slidably connected to the inner surface of the groove 354. The threaded slider 3553 can transmit the movement of the sliding plate 3551 to the L-shaped rod 356. At the same time, under the action of the limiting spring rod 3552, it maintains a tight fit with the inner wall of the groove 354 to ensure the stability of the transmission. When the threaded rod 353 rotates, the sliding plate 3551 is positioned relative to the threaded rod 353 under the limiting action of the groove 354. Through the sliding plate 3551 and the threaded slider 3553, the L-shaped rod 356 is driven to slide on the inner wall of the rectangular frame 31 and the L-shaped guide groove 36, and the table 351 is driven to move from the inside of the rectangular frame 31 to the outside.

[0040] Example 3: Based on Example 2, this example utilizes the linkage design between the support leg 21 and the protective box 2. Through the transmission structure of the buffer spring rod 216 driving the rack 215, gear 214, and rack 213, the protective box 2 unfolds and the support leg 21 automatically extends and retracts synchronously, eliminating the need for manual adjustment. The limit buckle 212 guides and limits the sliding rod 211, ensuring smooth movement of the support leg 21. The anti-slip support leg 217 increases friction with the ground, enhancing the stability of the device and preventing tilting or swaying during surveying. The buffer spring rod 216 also absorbs unexpected vibrations, preventing them from being transmitted to the digital surveying instrument 7 and affecting surveying accuracy.

[0041] For further details, please refer to [link / reference]. Figure 2 and Figure 7The support leg 21 includes a buffer spring rod 216 fixedly connected to the upper end of the bottom shell 1 via a connecting block. The buffer spring rod 216 has good elastic buffering performance and can buffer and dampen vibrations when the device is subjected to accidental vibrations, preventing vibrations from being transmitted to the digital surveying instrument 7 and affecting the surveying accuracy. A rack 215 is slidably connected to the outer surface of the buffer spring rod 216 via a spring. The spring allows the rack 215 to maintain a stable position under the elastic force of the buffer spring rod 216. A gear 214 is meshed at the upper end of the rack 215 and is rotatably connected to the inner wall of the protective box 2. The gear 214 can convert the linear motion of the rack 215 into its own rotational motion. A limiting buckle 212 is fixedly connected to the middle of the inner surface of the support leg 211. The limiting buckle 212 guides and limits the sliding rod 211, preventing it from tilting or shifting during extension and retraction, thus ensuring the smooth movement of the support leg 21. The sliding rod 211 is slidably connected to the inner surface of the limiting buckle 212. The sliding rod 211 is the main load-bearing component of the support leg 21 and can slide up and down along the inner surface of the limiting buckle 212. A rack 213 that meshes with the gear 214 is fixedly connected to the side of the sliding rod 211 away from the inner wall of the protective box 2. The rack 213 converts the rotational motion of the gear 214 into the linear motion of the sliding rod 211. The lower end of the sliding rod 211 is screwed... The device is connected to anti-slip support legs 217, which are made of anti-slip material. These legs increase friction when in contact with the ground, further enhancing the stability of the device and preventing tilting or shaking during surveying, thus ensuring the accuracy of the survey data. The bottom wall of the inner surface of the protective housing 2 has a through hole for the sliding rod 211 to pass through, allowing it to extend out of the housing and contact the ground. During the unfolding of the protective housing 2, the buffer spring rod 216 is stretched, and the rack 215 moves upward under the spring force of the buffer spring rod 216. As the rack 215 moves upward, it drives the gear 214 meshing with it to rotate. When rotated, the rack 213 meshing with it moves downward. The rack 213 drives the sliding rod 211 to slide downward along the inner surface of the limit buckle 212, so that the lower end of the sliding rod 211 passes through the through hole in the bottom wall of the inner surface of the protective box 2 and extends to the ground. The anti-slip leg 217 at the lower end of the sliding rod 211 is in close contact with the ground, completing the automatic extension action of the support leg 21. During the storage of the protective box 2, the buffer spring rod 216 is compressed, which drives the rack 215 to move downward. The rack 215 drives the rack 213 to move upward through the gear 214. The rack 213 drives the sliding rod 211 and the anti-slip leg 217 to slide upward and be stored in the inner cavity of the protective box 2.

[0042] Example 4: Based on Example 3, this example utilizes the linkage design between the surveying support structure 6 and the protective housing 2. The horizontal movement of the protective housing 2 is converted into the vertical movement of the lifting base 62 via the connecting rod 63, enabling synchronized operation of the protective housing 2's unfolding and storage and the digital surveying instrument 7's lifting and lowering. No separate lifting mechanism is required. The connecting groove 624 of the T-block 621 ensures the stability of the rotating connection of the connecting rod 63. The sliding block 612 provides radial guidance for the compression spring 613, ensuring stability during movement. The cross spring plate 614, linked with the roller 5, completes the extension and retraction action, while simultaneously absorbing ground vibrations to enhance the device's shock resistance. The bottom shell 1 directly contacts the ground, increasing placement stability. The electric threaded ring 623 and the threaded rod 622 work together to fine-tune the working height of the digital surveying instrument 7. The quick-release base facilitates the rapid installation, disassembly, and model change of the digital surveying instrument 7.

[0043] For further details, please refer to [link / reference]. Figure 7 The surveying support structure 6 includes a support base 61 fixedly installed on the upper end of the base shell 1. The support base 61 serves as the basic component of the surveying support structure 6, providing installation and sliding support for the lifting base 62. It also connects to the rollers 5 and related components inside the base shell 1. The inner surface of the support base 61 is provided with a lifting base 62 for driving the digital surveying instrument 7 to rise and fall. The lifting base 62 can slide up and down along the inner surface of the support base 61 to drive the digital surveying instrument 7 to complete the rising and falling action, while simultaneously linking the extension and retraction of the rollers 5. Both ends of the lifting base 62 are rotatably connected to connecting rods 63 that are rotatably connected to the inner wall of the protective housing 2. The connecting rods 63 serve as the connection between the protective housing 2 and... The transmission component of the lifting base 62 can convert the horizontal movement of the protective box 2 into the vertical movement of the lifting base 62. When the two protective boxes 2 move away from each other, the connecting rod 63 drives the lifting base 62 to move upward, realizing the synchronous unfolding of the protective box 2 and the rising of the digital surveying instrument 7. There is no need to operate the lifting mechanism separately, shortening the preparation time for unfolding the device. When the two protective boxes 2 are pushed towards each other, the protective box 2 drives the lower end of the connecting rod 63 to move inward, and the upper end of the connecting rod 63 moves downward, thereby driving the lifting base 62 to move downward along the inner surface of the support base 61, realizing the synchronous unfolding of the protective box 2 and the lowering of the digital surveying instrument 7.

[0044] For further details, please refer to [link / reference]. Figure 8 and Figure 9The support base 61 includes a central block 611 mounted on the upper end of the bottom shell 1. The central block 611 is the main structure of the support base 61, providing installation space for the compression spring 613 and the sliding block 612, and also guiding the sliding of the lifting base 62. The inner surface of the central block 611 is slidably connected to the compression spring 613, which is fixedly connected to the lower end of the lifting base 62. The compression spring 613 can transmit the movement of the lifting base 62 and has a certain elasticity, which can absorb some vibration. The inner cavity of the central block 611 is fixedly connected to the sliding block 612, which is sleeved on the outer surface of the compression spring 613. 612 acts as a radial guide for the compression spring 613, preventing radial deformation of the compression spring 613 during movement and ensuring the stability of the compression spring 613's movement. The lower end of the compression spring 613 extends through the central block 611 into the inner cavity of the bottom shell 1 and is fixedly connected to a cross spring plate 614 that is slidably connected to the inner cavity of the bottom shell 1. The cross spring plate 614 itself has good elastic damping performance, which can further absorb the vibration transmitted from the ground and improve the device's shock resistance. The lower end of the cross spring plate 614 is fixedly connected to the roller 5. The roller 5 is used for short-distance movement of the device to reduce the labor intensity of handling.

[0045] When the compression spring 613 is in its initial state, the roller 5 is located at the lower end of the base shell 1, allowing the device to move short distances via the roller 5. When the lifting base 62 rises, the compression spring 613 rises along with the lifting base 62 and drives the roller 5 back into the inner cavity through the cross spring plate 614. At this time, the base shell 1 is in direct contact with the ground, increasing the contact area between the device and the ground, improving the stability of the device placement, and preventing the device from sliding during the surveying process. When the lifting base 62 descends, the compression spring 613 descends synchronously with the lifting base 62. The compression spring 613 drives the roller 5 downward through the cross spring plate 614, causing the roller 5 to extend out of the lower end of the base shell 1, facilitating the movement of the device.

[0046] For further details, please refer to [link / reference]. Figure 8 and Figure 9The lifting base 62 includes a T-shaped block 621 slidably mounted on the inner surface of the central block 611 and fixedly connected to the upper end of the connecting rod 63. The T-shaped block 621 is the main structure of the lifting base 62 and can slide up and down along the inner surface of the central block 611 to transmit the movement of the connecting rod 63. An electric threaded ring 623 driven by a motor is rotatably mounted on the upper end of the T-shaped block 621. The electric threaded ring 623 is driven to rotate by a built-in motor to provide power for the height fine adjustment of the digital surveying instrument 7. A threaded rod 622 is threadedly connected to the inner surface of the electric threaded ring 623 and slidably connected to the inner surface of the T-shaped block 621. The threaded rod 622 can convert the rotational motion of the electric threaded ring 623 into its own vertical linear motion. The digital surveyor 7 is mounted on the upper end of the threaded rod 622 via a quick-release base. The quick-release base allows for rapid installation and removal of the digital surveyor 7, facilitating individual maintenance or replacement of the digital surveyor 7. It also allows for quick replacement of different models of the digital surveyor 7 to adapt to different surveying needs. The left and right ends of the T-block 621 are provided with connecting grooves 624 that rotatably connect with the connecting rod 63. The connecting grooves 624 provide an installation position for the connecting rod 63, ensuring the stability of the rotatable connection between the connecting rod 63 and the T-block 621. When the electric threaded ring 623 rotates, the threaded rod 622 moves upward or downward under the action of the thread, realizing the fine adjustment of the working height of the digital surveyor 7 to meet the height requirements of different surveying scenarios.
