[0041] The working principle of the surveying and mapping auxiliary surveying device in this embodiment is as follows:

[0042] The surveyor moves the device to the designated position, moves the support leg 3, and the top of the support leg 3 rotates axially around the first connecting ear plate 6. The end of the first support rod 16 near the fourth connecting ear plate 19 rotates axially around the fourth connecting ear plate 19, and the end of the first support rod 16 near the third connecting ear plate 18 rotates axially around the third connecting ear plate 18. The first slider 14 slides vertically upward along the first slide groove 17, and the first connecting plate 15 moves vertically upward with the first slider 14 to the threaded hole at the upper end of the support frame sidewall on the vertical movement path of the first connecting plate 15. The first fixing screw 20 is tightened to fix the first slider 1. 4. Position the support leg 3 in the first slide groove 17, loosen the locking nut 35, and rotate the handle 33. The first one-way screw 32 rotates with the handle 33, and the third slider 29 slides along the third slide groove 31 with the first one-way screw 32. The vertical rod 30 moves with the third slider 29, and the support foot 4 moves with the vertical rod 30. Roughly level the support frame, tighten the locking nut 35 to fix the position between the third slider 29 and the vertical frame 28, and move the support plate 9. One end of the support plate 9 rotates axially about the second connecting ear plate 10, and the end of the second support rod 23 near the sixth connecting ear plate 26 rotates axially about the sixth connecting ear plate 26. The second support rod 23 rotates axially around the fifth connecting ear plate 25 at one end, causing the second slider 21 to slide vertically downward along the second slide groove 24. The second connecting plate 22 moves vertically downward with the second slider 21 to the threaded hole at the lower end of the support frame sidewall on the vertical movement path of the second connecting plate 22. The second fixing screw 27 is tightened to fix the position of the second slider 21 in the second slide groove 24, supporting the support plate 9. The locking screw 11 is unscrewed, and the base 8 is pulled. The connecting rod 7 slides vertically along the slot of the fixing cylinder 2, the limiting block 12 slides vertically along the limiting groove 13, and the base 8 moves vertically downward. Until the bottom surfaces of the base 8 and support plate 9 contact the ground, tighten the locking screw 11 to fix the position of the base 8. Rotate the sleeve 37 respectively. The one-way screw moves vertically along the inside of the sleeve 37 as it rotates. Since the one-way screw is welded with a universal joint 39, the angle of the mounting plate 5 on the horizontal plane can be easily changed. The level bubble 42 can be used to easily determine whether the mounting plate 5 is in a horizontal position. The sleeve 37 can be adjusted according to the degree of deviation of the level bubble 42 to level the mounting plate 5. The surveying instrument is then installed on the mounting plate 5, and the leveling structure on the surveying instrument is used to level the instrument for surveying operations.
