Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a land planning measuring tool. Background Art

[0002] Land is the vital foundation for our survival and development, so good land planning is of great significance. Land planning includes the overall planning of agricultural land, urban land, and industrial land. Its purpose is to rationally allocate land resources and ensure their full and effective use. In land planning, an indispensable step is to measure the land area.

[0003] A Chinese patent with the search announcement number CN217504553U discloses a land planning measurement tool. Another person holds one end of the tape measure and pulls the rolled tape measure outward, so that the tape measure can be placed close to the ground for land measurement. The combination design of the No. 1 guide block and the No. 1 guide wheel and the No. 2 guide wheel inside the No. 2 guide block facilitates the guidance of the tape measure so that the tape measure can be placed close to the ground for measurement, which is beneficial to reducing measurement errors and thus improving the accuracy of the measurement results. The central shaft is then driven to rotate by the turning handle to reel in the tape measure. After reeling is completed, the dial block is reset and the positioning pin is re-connected to one end of the turning handle to achieve the positioning of the turning handle, thereby facilitating the reeling and tightening of the tape measure, facilitating actual measurement and use, having broad market prospects and being conducive to promotion.

[0004] Based on the above search and combined with the existing technology, it was found that the above patent has certain defects. Although the guide structure allows the tape measure to be close to the ground for measurement, in some occasions it is also necessary to lift the tape measure to a certain height for measurement. The guide structure cannot measure the height according to the actual site measurement requirements, and the scope of application is small, which reduces the efficiency of the use of land planning measurement tools.
