[0002] The surveying and mapping benchmark fixing device is used to fix the surveying and mapping benchmark to a specified position to prevent the surveying and mapping benchmark from tipping over during surveying and mapping.

[0003] For example, a surveying and mapping benchmark fixing device with the authorization announcement number "CN214843277U" realizes the function of enhancing stability and solves the problem of weak stability. It not only relies on the benchmark cone at the bottom to deeply penetrate into the place where the mark is required, but also increases the stability of the bottom of the benchmark. Even in windy weather or inadvertent external force touch, it will not easily tilt and fall, which better meets people's use needs and brings convenience to people's work. However, in the use of the surveying and mapping benchmark fixing device, the supporting rod is in a fixed integrated form, which makes it impossible to adjust the height. Sometimes the surveying instrument needs to measure the level and inclination angle according to the height of the surveying and mapping benchmark, which requires the operator to lift and support for a long time, which increases the difficulty of using the surveying and mapping benchmark fixing device and makes the surveying and mapping benchmark fixing device have usage limitations.

A round rod 203 is inserted below the front of the sleeve plate 202. A baffle 204 is fixedly connected to the front of the round rod 203. A compression spring 205 is sleeved on the outer wall of the round rod 203. The two ends of the compression spring 205 are respectively connected to the front and inner walls of the sleeve plate 202. The inner walls of the baffle 204 are fixedly connected. After the baffle 204 is forced to move forward, it rebounds by the elastic force of the compression spring 205.

The bottom of the outer wall of the vertical rod 302 is plugged into the top circular opening of the sleeve plate 202.

[0026] Working principle:

[0027] Installation of surveying and mapping benchmark fixture:

[0028] Make the bottom fit with the designated position, then install it through the bottom plate 1 and plug it into the ground, then plug the block 5 into the top of the sleeve plate 202, and then hold the bent rod 303, so that the bent rod 303 and the vertical rod 2 302 pass through the bracket 301 from top to bottom and plug it into the round opening on the top of the sleeve plate 202 to complete the position fixation of the reflector 7.

[0029] Use of surveying and mapping benchmark fixture:

[0030] When the laser emitted by the surveying and mapping device cannot illuminate the reflector 7, the handle 4 can be pulled forward, and the handle 4 moves forward with the baffle 204, and the moving baffle 204 moves forward with the round rod 203, and the outer wall rear of the moving round rod 203 is separated from the circular opening on the front of the vertical plate 201 (the first surveying and mapping benchmark), and then the sleeve plate 202 (the second surveying and mapping benchmark) moves upward on the outer wall of the vertical plate 201, and then moves upward with the reflector 7 fixed above, and then releases the handle 4 to compress the spring 205 to provide a rebound force to make the baffle 204 move backward with the round rod 203, so that the outer wall rear of the round rod 203 is plugged into the corresponding circular opening on the front of the vertical plate 201, and the height adjustment of the reflector 7 is completed.

[0033] Working principle:

[0034] When the sleeve plate 202 moves up and down, it will move up and down along the inner wall of the vertical pole 8 with the insertion rod 9. The vertical pole 8 cooperates with the insertion rod 9 to support and reinforce the sleeve plate 202, thereby preventing the sleeve plate from being deformed due to high lifting and strong wind.
