[0039] Example 2:

[0040] Please see Figure 5-7 Furthermore, in conjunction with Embodiment 1, the top of the sliding rod 316 is bolted to a support base 321. A scale 322 is fixedly connected to the top of the support base 321. A third gear rod 328 is fixedly connected to the top of the support base 321. An instrument housing 323 is rotatably connected to the outside of the third gear rod 328. A horizontal adjustment rod 326 is rotatably connected to one side of the instrument housing 323. A second bevel gear 329 is fixedly connected to the outside of the third gear rod 328. A first bevel gear 327 is fixedly connected to the outside of the horizontal adjustment rod 326 extending into the inside of the scale 322. A vertical adjustment rod 3210 is rotatably connected to one side of the instrument housing 323. A surveying instrument 324 is fixedly connected to the outside of the vertical adjustment rod 3210 extending into the inner top of the instrument housing 323. The top of the instrument 324 is rotatably connected to a focus adjustment rod 325. The end of the vertical adjustment rod 3210 away from the measuring instrument 324 is fixedly connected to a ratchet 3211. The bottom of the ratchet 3211 is engaged with a locking assembly 3212. The locking assembly 3212 includes a third spring 32124. The third spring 32124 is fixedly connected to the inside of one side of the instrument housing 323. The top of the third spring 32124 is fixedly connected to a locking plate 32125. The outside of the instrument housing 323 away from the vertical adjustment rod 3210 is rotatably connected to a lever 32121. The end of the lever 32121 near the inside of the instrument housing 323 is fixedly connected to a locking block 32122. The side of the locking block 32122 away from the lever 32121 is threadedly connected to a threaded rod 32123, making the instrument measurement more accurate.

[0041] Furthermore, the first bevel gear 327 and the second bevel gear 329 are meshed together, allowing the instrument to be adjusted horizontally, thus increasing measurement accuracy.

[0042] Furthermore, there are two sets of third springs 32124 and locking plates 32125, which are equidistantly distributed inside the instrument housing 323 on the side away from the vertical adjustment rod 3210 with the threaded rod 32123 as the center, and can control the vertical adjustment of the instrument back and forth.

[0043] In actual operation, when this device is used, firstly, the movable support column 23 is pulled. The second gear rod 223, which is fixedly connected to its top, rotates along the direction in which the movable support column 23 is pulled. When the movable support column 23 is pulled to a certain angle, the second gear rod 223 is engaged with the first gear rod 221, locking the movable support column 23. At the same time, the movable rod 26, which is hinged between the second collar 27 and the first collar 25, is also pulled to the corresponding angle, supporting the instrument. At this time, the movable rod 26 is then turned. The pad 24 at the bottom of the support column 23 allows the instrument stand to be placed more stably. When the instrument stand is stably placed, pressing the pressing plate 314 causes the first spring 313 to retract downwards. At the same time, the pin head 315 is pulled outwards from the sliding rod housing 311 as the pressing plate 314 is pressed. At this time, the sliding rod 316 is inserted into the sliding rod housing 311 and adjusted to the required length. Then, releasing the pressing plate 314 causes the first spring 313 to rebound upwards. At the same time, the pin head 315 is pulled outwards from the pressing plate 314. The loosening mechanism is inserted into the sliding rod housing 311 and the sliding rod 316 to fix the sliding rod 316. When the sliding rod 316 is fixed, the surveying component 32 is fixed to the sliding rod 316 by bolts. At this time, rotating the horizontal adjustment rod 326 causes the first bevel gear 327 to mesh and rotate along the second bevel gear 329, thereby driving the surveying instrument 324. This aligns the arrow on the instrument housing 323 with the scale on the dial 322, adjusting the horizontal angle of the surveying instrument 324. When the adjustment is complete, rotate the vertical adjustment lever 3210 to adjust the vertical angle of the surveying instrument 324, so that the infrared probes on the top of the surveying instrument 324 converge at one point, improving the accuracy of the measurement. Move the lever 32121 so that the locking block 32122 can alternately squeeze and rebound the locking plates 32125 on both sides, so that the locking plate 32125 on one side locks the ratchet 3211, allowing the vertical angle of the surveying instrument 324 to be adjusted back and forth. Finally, rotate the focus adjustment lever 325 to make the received image clearer.
