At the same time, as shown in fig. 8, the second spring 35 is extended to drive the movable rod 4 to move in a direction approaching the ground. And drives the first air chamber 301 to become larger so that the air enters the first air chamber 301 from the second air chamber 302. So that the sliding block 33 is moved in a direction approaching the inner case 31, thereby making the second air chamber 302 smaller. Then, the sleeve 41 abuts against the ground, and then no external force is applied to the opening and closing assembly 5, as shown in fig. 4, the first spring 52 shortens to drive the opening and closing member 51 to be inserted into the through hole 303 again, so as to separate the first air cavity 301 from the second air cavity 302. Then, the snap ring (not shown in the figure) is slid so that the snap ring (not shown in the figure) is sleeved outside the opening and closing member 51, and the inner wall of the snap ring (not shown in the figure) abuts against one end of the opening and closing member 51 located outside the casing 3, so that the opening and closing member 51 is prevented from being ejected out of the first air cavity 301 by air pressure of air. So that the movable rod 4 is fixed with respect to the housing 3. External force is then no longer applied to the mounting plate 1 so that the movable bar 4 and the first leg 2 support the mounting plate 1 and the sleeve 41 is rotated relative to the movable bar 4 as shown in fig. 6 and 10 to bring the sleeve 41 into axial movement along the movable bar 4 for a small extent of horizontal alignment of the mounting plate 1 to complete the horizontal adjustment of the mounting plate 1. Therefore, the real estate mapping bracket can conveniently and rapidly adjust the real estate mapping instrument to be horizontal.
