Description

Technical Field

[0001] This application relates to the field of land area measuring instruments, and more specifically, to a handheld portable land area rapid measuring instrument. Background Technology

[0002] GPS land area measuring instruments, also known as land area measuring instruments or handheld land area measuring instruments, integrate a high-precision GPS positioning system, accurate area calculation methods, and an intelligent handheld computer system. They can achieve real-time testing of irregular areas, dynamic graphic display, and intelligent data processing and storage, playing an important role in agricultural farmland area measurement and land registration.

[0003] A handheld land area measuring device, disclosed in patent CN220568109U, works by extending the measuring instrument outwards, causing a sliding column to move inside a sliding groove. This pulls a limiting rod out of the first limiting groove, and then rotating the measuring instrument inserts the limiting rod into the second limiting groove, placing the measuring instrument inside the outer casing. This design prevents the operator from being affected by the outer casing, facilitating operation and improving measurement efficiency. However, the inventor believes the following drawbacks exist: the measuring instrument in the comparative literature is housed within a protective device with a handle. During use, the operator must hold the handle for extended periods, which can lead to sweaty hands and the instrument and protective device potentially slipping and falling. Therefore, we propose a handheld portable land area rapid measuring instrument. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] The purpose of this application is to provide a handheld portable land area rapid calculation instrument, which solves the technical problem in the aforementioned background literature where the land area measuring instrument is stored and installed in a protective device with a handle. During use, the measuring personnel need to hold the handle for a long time, which can easily cause sweaty palms and lead to the land area measuring instrument and the protective device accidentally slipping out of their hands and falling to the ground. This portable GPS land area measuring instrument retains portability by using a protective shell, and the protective shell and cover provide a wrap-around protection. The protective shell is equipped with a leather strap, which places the measuring personnel's palm between the protective shell and the leather strap.
