[0002] Land planning refers to the arrangement and design of land use according to the needs of national economic and social development and the natural and economic conditions of each region. In order to formulate a more suitable plan, it is necessary to survey the land during land planning, so as to measure the specific values of the land. When conducting the survey, surveyors need to use instruments to measure at designated positions, so it is necessary to locate and mark the measurement positions before measurement.

[0003] After retrieving the Chinese patent with the publication number CN220187700U, a land planning survey and positioning device is disclosed. By pasting the positioning sticker on the ground, the measurement location can be marked. And through the push of the first handle and the first push plate, the positioning sticker can be directly pasted on the ground, and the pasting action can be completed continuously and quickly, which has convenience. At the same time, since the first connecting cylinder and the second connecting cylinder form a long rod, when surveyors walk on mountain roads and roads with poor road conditions, this device can support the surveyors and improve the stability of the surveyors when walking.

[0004] Based on the above retrieval and combined with the existing technology, it is found that the above patent has certain defects. When conducting survey and positioning, the measurement location is marked by pasting the positioning sticker on the ground. However, the positioning sticker has no limiting structure in the connecting cylinder and is easy to directly slide out, which cannot ensure that only one positioning sticker is pushed out each time. And it is very difficult to align with the positioning sticker when using the second connecting cylinder to recycle it, and the operation is not convenient enough, reducing the use efficiency of the land planning survey and positioning device.
