The outer surface of the connecting rod 10 is fixedly sleeved with a torsion spring 19, one end of the torsion spring 19 is fixedly connected to the outer surface of the connecting rod 10, and the other end of the torsion spring 19 is fixedly connected to the side inner wall of the connecting block 9, the fixed block 12 is adapted to the fixed groove 6, the side surface of the movable block 11 is in contact with the connecting block 9, the connecting rod 10 passes through the connecting block 9, and the number of connecting structures 21 is two and they are distributed in a circular array.

[0027] The fixed structure 22 includes a positioning plate 13, a sliding rod 14, a slide plate 15 and an insert block 16. The side surface of the positioning plate 13 is fixedly connected to the main rod 1, the outer surface of the sliding rod 14 is slidably connected to the positioning plate 13, the lower surface of the slide plate 15 is fixedly connected to the sliding rod 14, and the lower surface of the insert block 16 is fixedly connected to the slide plate 15. A slot 17 is provided on the movable block 11, and the outer surface of the insert block 16 is movably connected to the slot 17. The end of the sliding rod 14 away from the slide plate 15 is fixedly connected with an anti-slip block 18, and the upper surface of the anti-slip block 18 contacts the positioning plate 13. The outer surface of the sliding rod 14 is slidably sleeved with a spring 20, and one end of the spring 20 is fixedly connected to the upper surface of the positioning plate 13. The end of the spring 20 away from the positioning plate 13 is fixedly connected to the lower surface of the slide plate 15. There are two fixed structures 22 and they are distributed in a ring array.

[0028] Working principle: By pulling the anti-slip block 18 downward, the movable anti-slip block 18 can drive the slide bar 14, the slide plate 15 and the insert block 16 to move. At the same time, the slide plate 15 will gradually squeeze the spring 20 on the positioning plate 13 during the movement, so that the spring 20 is in a taut state. When the movable insert block 16 is disengaged from the slot 17, the fixation of the torsion spring 19 can be released, and the torsion spring 19 can be flipped and rebounded. The flipped and rebounded torsion spring 19 can drive the connecting rod 10 to rotate, so that the rotating connecting rod 10 can drive the movable block 11 and the fixed block 12 to flip with the connecting rod 10 as the central axis. When the flipped fixed block 12 is disengaged from the connecting groove 7 and the positioning groove 8, the fixation of the movable column 2 is released, and then the movable column 2 is pulled. When the movable column 2 is pulled out to a suitable length, the fixing slot 6 is aligned with the connecting slot 7, and then the movable block 11 is reversed, so that the movable block 11 drives the fixed block 12 to flip around the connecting rod 10 as the central axis, and the movable block 11 drives the connecting rod 10 to rotate during the flipping process, so that the rotating connecting rod 10 can drive the torsion spring 19 on the connecting block 9 to flip and stretch, thereby making the torsion spring 19 in a flipped and stretched state. When the flipped fixed block 12 is inserted into the fixing slot 6 and the connecting slot 7, the movable column 2 will no longer move, and the insert block 16 can correspond to the slot 17, and then After that, the anti-falling block 18 is released, so that the spring 20 is no longer restricted by the tension and rebounds, so that the rebounding spring 20 drives the slide bar 14, the slide plate 15, the plug block 16 and the anti-falling block 18 to move. When the movable plug block 16 is inserted into the slot 17, the fixation of the movable block 11, the fixed block 12 and the torsion spring 19 is completed, so that the torsion spring 19 always keeps the flipped and stretched state, and the fixed block 12 will not be separated from the fixing groove 6 and the positioning groove 8, thereby completing the fixation of the movable column 2, so that the movable column 2 will not be retracted into the main rod 1. Then, the benchmark is inserted into the soil as a whole through the tapered block 5, and after rotating the tapered block 5, the tapered block 5 and the threaded column 4 can be unscrewed from the main rod 1, so that the tapered block 5 can be separately packed and carried. When the connection between the main rod 1 and the threaded column 4 and the tapered block 5 is made, the threaded column 4 is rotated in the opposite direction to tighten the threaded column 4 on the main rod 1. When the device is used up, the anti-dropping block 18 is pulled to move the slide bar 14, the slide plate 15 and the plug block 16 while keeping the spring 20 in a taut state. When the movable plug block 16 is disengaged from the slot 17, the fixation of the torsion spring 19 is released, so that the torsion spring 19 that rebounds can drive the movable block 11 and the fixed block 12 to flip. When the flipped fixed block 12 is disengaged from the fixing groove 6 and the connecting groove 7, the fixation of the movable column 2 is released, and then the connecting plate 3 is pressed so that the movable column 2 can be received in the main rod 1, and the connecting groove 7 corresponds to the positioning groove 8, and then the movable block 11 is flipped in the opposite direction.The flipped movable block 11 drives the fixed block 12 to flip and insert into the connecting slot 7 and the positioning slot 8. Then, the anti-dropping block 18 is released, causing the torsion spring 19 to rebound. The rebounded torsion spring 19 drives the slide bar 14, the slide plate 15, the insert block 16, and the anti-dropping block 18 to move. When the movable insert block 16 is inserted into the slot 17, the fixed block 12 is fixed. At the same time, the movable column 2 is fixed, so that the movable column 2 will not fall out of the main pole 1. The movable column 2 is stored, reducing the overall length of the benchmark and facilitating its portability.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
