[0030] Specific working principle:

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, when the construction engineering design measuring instrument is used, the fixing rod 1 is lifted from the inner end of the storage groove 9, so that the connecting disk 13 rotates at the outer end of the rotating shaft 14, and then the lower end of the limiting plate 12 is engaged with the inner end of the sliding groove 11, and the limiting plate 12 is pushed backward, so that the limiting plate 12 is engaged with the lower part of the fixing rod 1, and the limiting plate 12 is pushed backward continuously, so that the opening 15 opened at the inner end of the limiting plate 12 is engaged with the outer end of the connection position between the fixing rod 1 and the connecting disk 13, so as to limit the fixing rod 1, and the measuring instrument body 16 is installed on the top of the adjusting rod 2;

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the micro servo motor 4 is started, and the output end of the micro servo motor 4 drives the threaded screw 5 to rotate when rotating. Under the limiting condition of the limit rod 8, the threaded groove 7 at the inner end of the adjusting rod 2 can only move upward or downward at the outer end of the threaded screw 5. According to the height to be adjusted, the measuring instrument body 16 is adjusted to the required height.
