Then, by pulling the second bracket, the second bracket slides inside the first bracket, and the sliding rod limits the second bracket. After the second bracket slides to the appropriate position, the second bracket is squeezed and fixed by the bolt. In this way, the height of the level body surveying and mapping can be adjusted, thereby improving the adaptability during use. BRIEF DESCRIPTION OF THE DRAWINGS

A supporting pillar 8 is fixedly connected to the bottom of the pressure plate 6. The supporting pillar 8 passes through the slide groove 3. A compression spring 9 is connected to the outer shell of the supporting pillar 8. Because the compression spring 9 is provided, when the level body 11 is above the pressure plate 6, the compression spring 9 is squeezed and compressed. When the level body 11 is removed, the level body 11 moves upward, and the compression spring 9 rebounds through the pressure plate 6 to drive the hook 7 to rotate and open between the corresponding two fixed blocks 5, so that the hook 7 is disengaged from the clamping of the card plate 12, thereby facilitating the removal of the level body 11. The end of the support pillar 8 is fixedly connected to the baffle 10;

[0020] A level body 11 is provided above the second triangular plate 4, and a clamping plate 12 is provided on the outer wall of the level body 11. A positioning pillar 13 is fixedly connected to the bottom of the level body 11. A positioning hole 14 is provided above the first triangular plate 2, and the position of the positioning pillar 13 corresponds to the position of the positioning hole 14. A plurality of connecting blocks 15 are fixedly connected to the bottom of the support plate 1, and a first bracket 16 is rotatably connected between the two corresponding connecting blocks 15. There are three first brackets 16. Two sliding rods 17 are fixedly connected to the inside of the first bracket 16. Because the sliding rod 17 is provided, the sliding rod 17 limits the second bracket 18, so that the second bracket 18 is smoother when extending, avoiding the position of the second bracket 18 from shifting during the extension process. The inside of the first bracket 16 is slidably connected to the second bracket 18, and the sliding rod 17 passes through both sides of the second bracket 18. A bolt 19 is provided on one side of the first bracket 16. Because the second bracket 18 is provided, the second bracket 18 The sliding connection allows the height of the level instrument body 11 to be adjusted to meet the measurement requirements of different heights. At the same time, the second bracket 18 is fixed by the bolt 19 to ensure the stability of the second bracket 18 after extension to prevent accidental sliding. A support column 20 is fixedly connected to the bottom of the support plate 1, and the outer wall of the support column 20 is slidably connected to the sliding sleeve 21. The outer wall of the sliding sleeve 21 is fixedly connected to three groups of lower rotating blocks 22. One side of the lower rotating block 22 is rotatably connected to the support arm 23, and the end of the support arm 23 away from the lower rotating block 22 is rotatably connected to the upper rotating block 24. One side of the upper rotating block 24 is connected to one side of the first bracket 16. Through the cooperation between the sliding sleeve 21 and the lower rotating block 22, the sliding sleeve 21 slides on the outer wall of the support column 20, and drives the support arm 23 to rotate through the lower rotating block 22. The support arm 23 drives the first bracket 16 to rotate between the corresponding connecting blocks 15 through the upper rotating block 24 to synchronously open or close, thereby realizing the rapid deployment and storage of the level instrument body 11.

[0021] The working principle of the present utility model is as follows: when using the level body 11, by pulling one of the first brackets 16, the first bracket 16 rotates between the corresponding two connecting blocks 15, and the support arm 23 is driven to open by the upper rotating block 24. During the opening process of the support arm 23, the sliding sleeve 21 is driven to slide on the outer wall of the support column 20 by the lower rotating block 22. During the sliding process of the sliding sleeve 21, the three first brackets 16 are driven to open synchronously. After the bolt 19 is loosened, the second bracket 18 is pulled to adjust the extension length of the second bracket 18. Then, the second bracket 18 is fixed by the bolt 19, and the positioning pillar 13 of the level body 11 is inserted into the positioning hole 14 of the first triangle plate 2. During the insertion process, the bottom of the level body 11 squeezes the three pressure plates 6 on the inner wall of the second triangle plate 4, and the pressure plate 6 drives the supporting pillar 8 to slide in the slide groove 3 to squeeze the compression spring 9. At the same time, the pressure plate 6 drives the hook 7 to rotate between the corresponding two fixed blocks 5, so that the three hooks 7 are closed to clamp the card plate 12 on the outer wall of the level body 11, thereby fixing the level body 11 for use.
