In order to facilitate the processing of the auxiliary support 1 and simplify the installation and fixing process of the spherical observation member 9, the limiting hole 14 can be processed into a through hole, and then a bearing member 15 is arranged on the auxiliary support 1, the bearing member 15 is plugged at one end of the limiting hole 14 and connected with the spherical observation member 9, and the bearing member 15 and the measuring device 5 are located on opposite sides of the auxiliary support 1.

[0040] In an embodiment, the to-be-observed point 2 is the top point of the protruding position on the upper part of the settlement observation marker 101. In order to facilitate the fixation of the to-be-observed point 2, the auxiliary support 1 is provided with a containing groove 16. When the auxiliary support 1 is arranged parallel to the horizontal plane, the groove bottom of the containing groove 16 is parallel to the horizontal plane, and the groove bottom of the containing groove 16 and the installation reference point 12 are at the same height.

The adjusting screw structure 312 can move the adjusting member 32 along the height direction, and drive the auxiliary support 1 connected with the adjusting member 32 to move along the height direction, so as to adjust the inclination angle of the auxiliary support 1 relative to the horizontal plane. When the auxiliary support 1 is adjusted by means of the screw structure 312, due to the characteristics of the screw structure 312, the linear displacement corresponding to each rotation angle is small and uniform. The adjustment by means of the screw structure 312 can accurately control the position change of the auxiliary support 1, and the position deviation or instability phenomenon caused by excessive adjustment amplitude can be avoided, thereby meeting the high adjustment precision requirement of the measurement operation. In addition, the first mounting hole 13 can be formed on the auxiliary support 1, and the second mounting hole 3111 can be formed on the support plate body 311. The axis of the first mounting hole 13 and the second mounting hole 3111 coincides and is perpendicular to the horizontal plane.

The connecting cylinder 3123 is sleeved on the outer circumferential side of the threaded rod 3122. One end of the connecting cylinder 3123 is connected with the support plate body 311, and the other end of the connecting cylinder 3123 abuts against the adjusting nut 3121. Rotating the adjusting nut 3121 can drive the connecting cylinder 3123 to move along the height direction, and make the support plate body 311 move along the height direction, so as to drive the adjusting member 32 to move along the height direction. The movement of the adjusting member 32 along the height direction can drive one end of the auxiliary support 1 connected thereto to move along the height direction synchronously. The whole process can be realized by rotating the adjusting nut 3121. The adjusting process is simple, and when the adjusting nut 3121 is rotated, the movement of the connecting cylinder 3123 can be continuous and smooth, avoiding measurement errors or damage to the measuring equipment 5 caused by large amplitude position changes.

The second fastener 8 is detachably arranged on the support plate body 311. A second through hole is formed in the support plate body 311. The second fastener 8 can pass through the second through hole and be connected with the other end of the adjusting member 32. The first fastener 7 and the second fastener 8 can be used to connect and fix the adjusting member 32 with the auxiliary support 1 and the support plate body 311 respectively. When the adjusting screw structure 312 is adjusted, the adjusting member 32 will not shake when moving along the height direction. The first fastener 7 and the second fastener 8 can improve the stability and safety and reliability of the adjusting process. Figure 6 As shown in one embodiment, the first fastener 7 includes a clamping portion 71, a penetrating portion 72, and an operating portion 73. The clamping portion 71 is in the shape of a circular arc and is prearranged in the first through hole. The penetrating portion 72 is rotationally arranged on the auxiliary support 1 and at least partially penetrates out of the auxiliary support 1. One end of the penetrating portion 72 is connected with the clamping portion 71, and the other end is fixedly connected with the operating portion 73. The operating portion 73 and the penetrating portion 72 can be threadedly matched. After the adjusting member 32 passes through the second mounting hole 3111 into the first mounting hole 13, slowly rotating the operating portion 73 can make the penetrating portion 72 apply a force to the clamping portion 71 to finely adjust the position of the clamping portion 71 until the clamping portion 71 abuts against the outer surface of the adjusting member 32. The second fastener 8 has the same structure as the first fastener 7. By finely adjusting the first fastener 7 and the second fastener 8, the fixing effect between the two ends of the adjusting member 32 and the support plate body 311 and the auxiliary support 1 respectively can be enhanced.
