[0002] Engineering surveying instruments are instruments and devices designed and manufactured for surveying and mapping operations, such as data collection, processing, and output. They are instruments for various types of orientation, distance, angle, height, mapping, and photogrammetry required for surveying work during the planning, design, construction, and management stages of engineering construction. They generally need to be supported by a positioning mechanism, which is mainly composed of a mounting plate and a tripod.

[0003] After the surveying instrument is installed, it needs to be positioned, which often leads to a tilting problem. Announcement No. CN219300360U discloses a positioning mechanism for an engineering surveying instrument, in which a geared disc fixedly connected to the bottom end of the handle drives a movable disc to rotate, so that the surveying instrument can be rotated and adjusted. A positioning nut provided at one end of a positioning rod cooperates with a limit sleeve to position the mounting disc. However, there are certain defects in use. When the positioning mechanism in the prior art is used through the positioning nut, it is difficult to achieve fast and accurate adjustment of the surveying instrument, and it is difficult to prevent the position of the surveying instrument from shifting, and the stability is poor.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention
