[0026] Specifically, by rotating the support column 9, the second slide column 14 and the second adjusting rod 12 are driven by the support column 9 to adjust the clamping shell 20 under the limit of the sleeve column 2, so as to achieve the effect of lateral adjustment of the theodolite body 27, and the worm 18 is driven by the connecting rod 17 to drive the worm wheel 8, and the worm wheel 8 drives the connecting column 7 to rotate on the inner wall of the connecting box 15, so as to drive the swivel 6 to drive the adjusting block 5 to drive the adjusting ring 3 to slide on the outer wall of the sleeve column 2 under the limit of the first slide groove 4, and drive the first adjusting rod 10 and the first slide column 11 to move, and the first slide column 11 drives the second adjusting rod 12 to rotate under the limit of the second slide column 14 under the limit of the second slide groove 13, so as to achieve the effect of longitudinal adjustment of the theodolite body 27 during use, and the multiple adjustment effects can be better used and improve the measurement efficiency during use.
