Then, push the movable rod 12, and the movable rod 12 drives the connecting block 24 to attract the magnetic block 23, so that the opposite end of the mounting rod 25 is inserted into the insertion groove 28, so that the mounting rod 25, the magnetic block 23 and the connecting block 24 limit the movable rod 12 after it is closed.

[0038] Please see Figure 1 , Figures 5-6 As shown, this embodiment, based on the above embodiment, further includes:

[0039] Limiting components;

[0040] The limiting assembly includes a circular rod 31, a soft pad 32, and a circular groove 33; the circular rod 31 is located below the movable rod 12, the soft pad 32 is fixed to the outer surface of the circular rod 31, and the circular groove 33 is opened inside the circular rod 31. The circular rod 31 is threadedly connected to the lower part of the movable rod 12 through the circular groove 33.

[0041] The circular rod 31 is used to open the circular groove 33, the soft pad 32 is used to protect the circular rod 31, and the circular groove 33 is used to insert the bottom end of the movable rod 12. By setting the circular rod 31 and the soft pad 32, the bottom end of the movable rod 12 can be protected to prevent the bottom end of the movable rod 12 from being worn due to long-term use, and at the same time avoid the inability to replace the bottom end of the movable rod 12 after it is worn.

[0042] An annular block 34 is engaged inside the circular groove 33, and a connecting rod 35 is fixedly connected to the top of the annular block 34. The connecting rod 35 is inserted into the bottom end of the movable rod 12.

[0043] A spring 36 is fixedly connected between the bottom end of the annular block 34 and the inner end of the circular groove 33, and a groove is provided at the bottom end of the movable rod 12 at the insertion point with the docking rod 35.

[0044] The annular block 34 is used to connect the connecting rod 35, the connecting rod 35 is used to limit the bottom end of the movable rod 12, the spring 36 is used to absorb the impact force on the movable rod 12, and the groove is used for the insertion of the connecting rod 35. When the bottom end of the movable rod 12 is inserted into the circular groove 33, it causes the connecting rod 35 to be inserted into the groove at the bottom end of the movable rod 12, so that the connecting rod 35 and the spring 36 limit the inserted movable rod 12.

[0045] Working principle: When the component is not in use, the bottom end of the movable rod 12 is not inserted into the circular groove 33. When the component is in use, hold the circular rod 31 by hand and insert the bottom end of the movable rod 12 into the circular groove 33. This causes the connecting rod 35 to be inserted into the groove at the bottom end of the movable rod 12. This allows the connecting rod 35 and the spring 36 to limit the movable rod 12 after insertion. When the surveying instrument is subjected to a certain degree of impact, the impact force is pushed by the movable rod 12 to continuously expand and contract the spring 36. This allows the spring 36 to absorb the impact force on the movable rod 12 and prevent the support and surveying instrument from falling over.
