Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0027] like Figure 1 As shown, the present invention proposes a surveying pole, including a pole body 1. The top of the pole body 1 is provided with a handle hole for easy hand holding. A rectangular groove 2 is provided on one side of the pole body 1, and scale lines 3 are printed in the rectangular groove 2 for observation and viewing.

[0028] like Figure 1-2As shown, in this embodiment, the marker body 1 is provided with a protective component to cover the scale line 3. The protective component includes a cover plate 4 slidably installed on both sides of the marker body 1 for covering the scale line 3. Mounting holes communicating with rectangular grooves 2 are provided on both sides of the marker body 1. The cover plate 4 is slidably connected to the inner wall of the mounting hole, achieving a sliding connection between the cover plate 4 and the marker body 1 through the mounting hole. During use, the cover plate 4 can be moved without blocking the scale line 3. After surveying, the cover plate 4 can be moved so that when the two cover plates 4 come into contact with each other, the scale line 3 is covered, effectively preventing scratches from external objects. A gap is provided between the cover plate 4 and the scale line 3, ensuring that the movement of the cover plate 4 will not touch the scale line 3, thus protecting the scale line 3.

[0029] like Figure 3 As shown, screws 7 are rotatably mounted on both sides of the marker body 1, and connecting blocks 6 are fixed on the cover plate 4. The connecting blocks 6 are rotatably connected to the screws 7. Two handles 8 are fixed to the end of the screws 7. Rotating the handles 8 drives the screws 7 to rotate, causing the connecting blocks 6 to move and the cover plate 4 to move and adjust. The adjustment is controlled by the screw thread, which is convenient and will not move arbitrarily after adjustment.

[0030] Working principle: Rotating the handle 8 drives the screw 7 to rotate, which in turn moves the connecting block 6 and the cover plate 4 to move and adjust. The adjustment is controlled by the screw thread, which is convenient and prevents random movement after adjustment. When the two cover plates 4 come into contact with each other, they cover the scale line 3, effectively preventing scratches from external objects and improving the service life of the surveying pole. Example

[0031] like Figure 2 and Figure 4 As shown in Embodiment 1, sleeves 9 are fixed to both sides of the marker body 1. An insert rod 5 is slidably installed inside the sleeves 9, with its bottom slidably penetrating the sleeves 9. The bottom of the insert rod 5 has a conical structure. A limiting device for fixing the position of the insert rod 5 is provided on the sleeves 9. The limiting device includes a threaded bolt 11. Multiple threaded grooves 10 are provided on the curved surface of the insert rod 5 to fit the bolt 11. Rotating the bolt 11 into the corresponding threaded groove 10 restricts the position of the insert rod 5. The bottom of the insert rod 5 is inserted into the soil for erecting the marker. When not in use, the bottom of the insert rod 5 is moved into the sleeve 9 to prevent accidental injury to others during transport.

[0032] It is worth noting that a baffle is fixed to the top of bolt 11. The cross-sectional area of ​​the baffle is larger than that of sleeve 9. The baffle prevents the insertion rod 5 from disengaging from sleeve 9.

[0033] The above specific embodiments are merely several optional embodiments of this utility model.
