[0002] Simply put, a surveying instrument is an instrument and device designed and manufactured for surveying and mapping operations, for data collection, processing and output. It is used for various orientation, distance, angle, height, mapping and photogrammetry required for surveying work in the planning, design, construction and management stages of engineering construction. The height and angle of existing surveying instruments are generally fixed and cannot be adjusted. The height and angle cannot be adjusted according to the needs of the measured object, which greatly limits the surveying and mapping scope and affects the surveying and mapping efficiency and practicality of the surveying and mapping instrument.

[0003] A Chinese patent discloses a surveying instrument that is convenient for adjusting the surveying height (authorization announcement number CN214663246U). The patented technology causes the first bevel gear and the second bevel gear to mesh and rotate by rotating the rotating rod, so that the sleeve drives the first wedge plate to move up and down, and pushes the second wedge plate to move left and right, so that the moving assembly drives the fixed block to move up and down, and the pull rope is driven by pulling the pull ring to pull the T-shaped plate to move, and the gear can be limited when the rotating assembly rotates, which is convenient for fixing the surveying instrument when adjusting the angle, and can be adjusted according to the height and angle of different measured objects, which is conducive to improving the flexibility and measurement efficiency of the device;

[0004] However, it has certain disadvantages: it can only adjust the horizontal angle of the surveying instrument, but cannot adjust the vertical angle of the surveying instrument, so it does not meet more usage requirements. Utility Model Content
