The second connecting shaft 205 is connected to the mounting platform 206 by bolts. The first connecting shaft 203 and the second connecting shaft 205 are vertically arranged. Through the arrangement of the first connecting shaft 203 and the second connecting shaft 205, the movable frame 204 and the mounting platform 206 can rotate relative to each other, so that when the fixed frame 201 is at any tilt angle, the mounting platform 206 can rotate to a horizontal state.

[0030] In this embodiment, the suspension mechanism includes a plurality of connecting rods 301 evenly distributed in an annular shape, the connecting rods 301 are connected to the bottom of the mounting platform 206 by bolts, one end of the connecting rod 301 away from the mounting platform 206 is connected to a connecting seat 302 by bolts, the axis of the connecting seat 302 is on the same straight line as the axis of the mounting platform 206, a sphere 303 is connected to the connecting seat 302 by bolts, the material of the sphere 303 is iron, and the gravity exerted on the sphere 303 is transmitted to the mounting platform 206 through the connecting seat 302 and the connecting rod 301.

[0031] In this embodiment, the first locking mechanism includes a first connecting plate 401, which is connected to a supporting leg 202 by bolts, and two symmetrically arranged locking blocks 402 are slidably connected to the first connecting plate 401, and an anti-slip layer is provided on the opposite side of the locking block 402, and a groove matching the locking block 402 is opened, and the locking block 402 is located on both sides of the first connecting shaft 203, and the first connecting plate 401 is connected to the first mounting block 403 by bolts, and the first mounting block 403 is rotatably connected to the first bidirectional screw rod 404, which is threadedly connected to the two locking blocks 402. When the first bidirectional screw rod 404 rotates, the first bidirectional screw rod 404 drives the locking blocks 402 to move relative to each other, and the locking blocks 402 approach each other, so as to clamp the first connecting shaft 203 from both sides to prevent the first connecting shaft 203 from rotating.

[0032] In this embodiment, the second locking mechanism includes a second connecting plate 501, which is connected to a support leg 202 by bolts, and an arc rod 502 is slidably connected to the second connecting plate 501, and an anti-slip layer is provided on the opposite side of the arc rod 502.

The arc rods 502 are close to each other and can clamp the second connecting shaft 205 to prevent the second connecting shaft 205 from rotating.

[0033] In this embodiment, a T-slot 506 is provided on the first connecting plate 401 and the second connecting plate 501, and a T-block 507 is connected to the bottom of the locking block 402 and the arc rod 502 by bolts. The T-block 507 is slidably set in the T-slot 506. The setting of the T-slot 506 and the T-block 507 guides the movement of the locking block 402 and the arc rod 502.

[0034] In this embodiment, the connecting mechanism includes a rotating piece 601, which is rotatably connected to the top of the second fixing bolt 104. The top of the rotating piece 601 is connected to a lifting rod 602 by bolts, and the top of the lifting rod 602 is connected to a connecting block 603 by bolts.

The first rack 604 is meshed with the first gear 405, and the second rack 605 is meshed with the second gear 505. The lifting rod 602 is slidably connected with a guide sleeve 606, and the guide sleeve 606 is connected to the support leg 202 by bolts. When the staff rotates the second fixing bolt 104, the second fixing bolt 104 rotates and descends relative to the moving seat 101 and drills into the ground. The movable seat 101 plays a fixing role. At the same time, the second fixing bolt 104 drives the rotating piece 601 to descend. The rotating piece 601 drives the connecting block 603 to descend through the lifting rod 602. The first rack 604 on the connecting block 603 drives the first gear 405 to rotate. The first gear 405 drives the first bidirectional screw rod 404 to rotate, so that the locking blocks 402 are close to each other, and the first connecting shaft 203 is clamped and fixed. The second rack 605 drives the second gear 505 to rotate. The second gear 505 drives the second bidirectional screw rod 504 to rotate. The second bidirectional screw rod 504 drives the arc rod 502 to approach each other, and the second connecting shaft 205 is clamped and fixed. When the second fixing bolt 104 fixes the movable seat 101, the horizontal structure is limited. When the device is fixed at the surveying position, the surveying device 208 remains horizontal and is prevented from shaking due to external force.

[0035] Working principle: When the device is in use, the mobile seat 101 is moved to the designated survey position. Since the gravity of the sphere 303 is transmitted to the mounting platform 206 through the connecting seat 302 and the connecting rod 301, the second connecting shafts 205 on both sides of the mounting platform 206 and the first connecting shafts 203 on both sides of the movable frame 204 rotate, so that the mounting platform 206 is always in a horizontal state, ensuring the survey effect of the survey device 208 on the mounting seat 207. First, the first fixing bolt 103 is rotated, and the bottom of the first fixing bolt 103 is drilled into the ground to initially fix the device. Then, the survey device 208 is kept horizontal and facing the survey position, and then the second fixing bolt 104 is rotated. During the rotation process, the second fixing bolt 104 rotates and drills into the ground to fix the mobile seat 101. At the same time, the second fixing bolt 104 drives the rotating plate 601 to descend, and the rotating plate 601 The connecting block 603 is driven down by the lifting rod 602, and the first rack 604 on the connecting block 603 drives the first gear 405 to rotate, and the first gear 405 drives the first bidirectional screw rod 404 to rotate, so that the locking blocks 402 are close to each other, and the first connecting shaft 203 is clamped and fixed, and the second rack 605 drives the second gear 505 to rotate, and the second gear 505 drives the second bidirectional screw rod 504 to rotate, and the second bidirectional screw rod 504 drives the arc rod 502 to approach each other, and the second connecting shaft 205 is clamped and fixed, and while the second fixing bolt 104 fixes the moving seat 101, the horizontal structure is limited, so that while the device is fixed at the surveying position, the surveying device 208 remains horizontal and is prevented from shaking due to external force. After the survey is completed, the first fixing bolt 103 and the second fixing bolt 104 are rotated in the opposite direction, and the moving seat 101 can be removed, which facilitates the installation and disassembly work.
