At the same time, by combining an adjustment component and a trigger component, multi-point support is achieved, effectively dispersing the weight and force of the device, preventing the offset of surveying data caused by device movement or shaking during the use of the surveying instrument, thereby ensuring the accuracy and reliability of the surveying results, and further providing a stable surveying platform, ensuring that the surveying instrument can quickly achieve measurements in multiple aspects such as horizontal angle, vertical angle, distance (slant distance, horizontal distance), and height difference measurement, thus ensuring the accuracy and credibility of the surveying data.

[0017] 2. The present invention can be stably placed on a suitable support point in a terrain with complex topography, ensuring that the device can be firmly placed on uneven ground, ensuring the stability and levelness of the device under complex conditions, and being able to effectively disperse the weight and force of the device, reducing the pressure and vibration on the ground, thereby protecting the stability and surveying accuracy of the surveying instrument. At the same time, especially on high-relief or sloping terrains, it can make the center of gravity of the surveying device move downward to adjust the center of gravity and improve the stability of the device, helping to prevent the device from tilting or moving due to unstable center of gravity.

[0046] For example, in one embodiment: The installation component 20 and the threaded rod 43 provided at the bottom of the surveying instrument 40 can quickly and accurately adjust the direction and angle of the surveying instrument 40, and then quickly measure the horizontal angle, vertical angle, distance (slant distance, horizontal distance), height difference, etc. using the surveying instrument 40.

[0047] For example, in one embodiment: When the surveying equipment needs to be placed on a horizontal ground, loosen the second locking sliding block 126 and the first locking sliding block 124 in the tripod 12, so that the two first sliding columns 125 and the second sliding column 127 can respectively move down along the two first sliding holes 129 and the second sliding holes 131 until the required height is reached, then tighten the second locking sliding block 126 and the first locking sliding block 124. Subsequently, rotate and open the three tripods 12 around the three first rotating mounting platforms 111, then rotate and open the fixed mounting bar 51, so that the bottom surface of the first rotating mounting block 511 abuts against the bottom surface of the first rotating mounting groove 133. Subsequently, rotate and open the two clamping mounting bars 55, so that the bottom surface of the second rotating mounting block 551 abuts against the bottom surface of the first rotating mounting groove 133, and the inner ends of the two clamping mounting bars 55 are clamped in the two clamping installation grooves 521 away from the fixed mounting bar 51. Subsequently, slidably insert the fourth universal ball 333 into the fourth universal shaft 54 to complete the smooth opening of the surveying equipment, so that the surveying equipment can perform multi-point support and disperse the unloading force, ensure the stability of the surveying instrument 40 during the surveying process, and prevent the occurrence of deviation during the surveying process, resulting in a decrease in surveying accuracy.

[0048] For example, in one embodiment: When it is necessary to place the surveying and mapping equipment in a terrain with complex topography, the above-mentioned operation process will be repeated. First, the surveying and mapping equipment is turned on, and the bottom end of the second sliding column 127 in one of the tripod legs 12 can be made to abut against the high point of the terrain with complex topography. Subsequently, the second locking sliding block 126 in the other two tripod legs 12 is loosened, so that the two first sliding columns 125 will slide downward along the two first sliding holes 129 under the action of gravity or manual pushing. Since the inner ends of the two elastic sliding strips 138 are respectively arranged in the two first sliding holes 129, and the diameters of the two first sliding columns 125 gradually decrease from top to bottom, the elastic sliding strips 138 will move outward along the inclined sliding grooves 135, causing the adjustable sliding square tube 136 and the magnet core 137 to move outward synchronously, causing the telescopic connecting strip 143 to extend. Since the magnetic pole magnetism of the magnetic sliding strip 561 is the same as that of the magnet core 137, the magnetic sliding strip 561 will move outward along the first sliding trigger cavity 512 or the second sliding trigger cavity, causing the trigger spring 562 to be compressed. At this time, the compression force of the trigger spring 562 on the other two tripod legs 12 will be greater than the compression force of the trigger spring 562 on the other tripod legs 12, breaking the balance of the abutting force of the three rubber extrusion strips 563 on the trigger rotating ring 53. The first abutting surface 564 of the two rubber extrusion strips 563 whose trigger springs 562 are compressed will push the trigger rotating ring 53, causing the trigger rotating ring 53 to tilt and rotate around the connecting cylinder 52. The outer ends of the two compressed rubber extrusion strips 563 will move outward along the clamping installation groove 521, and their first abutting surfaces 564 will abut against the bottom surfaces of the two trigger sliding strips 531. At the same time, the second abutting surface 565 of the outer end of the other rubber extrusion strip 563 will abut against the top surface of the other trigger sliding strip 531 until a new balance point is reached. At the same time, when the trigger rotating ring 53 tilts and rotates, the fourth universal ball 333 will pass through the trigger communication groove 541 far from the larger compression amount of the trigger spring 562 and move along the trigger spherical sliding groove 532. As a result, the adjusting rod 33 will synchronously move downward in an inclined manner, causing the third universal shaft 345 to move accordingly, causing the adjusting mounting turntable 341 to move accordingly, causing the three connecting elastic bands 343 to extend and stretch, causing the hanging weight to move accordingly, causing the center of gravity of the surveying and mapping equipment to move downward, and making the surveying and mapping equipment more stable.

[0049] For example, in one embodiment: when the bottom surface of the first locking sliding block 124 abuts against the top surface of the adjusting mounting bar 123 and the bottom end of the second sliding column 127 still cannot abut against the ground at the low point of the complex terrain, the first locking sliding block 124 will be tightened, and then the second locking sliding block 126 will be opened. Since the elastic sliding bar 138 has elasticity and the outer end of the elastic sliding bar 138 is rotatably mounted in the two rotating mounting columns 142, when the elastic sliding bar 138 moves outward along the inclined sliding groove 135, it will cause the outer end of the elastic sliding bar 138 to deform towards the center of the mounting cavity 134. When the first sliding column 125 descends to the lowest point, the bottom surface of the triangular abutting block 130 will abut against one side of the outer end of the center slider 139. When the second locking sliding block 126 is opened, the second sliding column 127 will slide downward along the second sliding hole 131 under the action of gravity or manual pushing. Since the diameter of the second sliding column 127 gradually decreases from top to bottom, it will cause the center slider 139 to slide outward along the mounting cavity 134, so that the adjusting sliding square tube 136 and the magnet core 137 further slide outward.
