Description

Technical Field

[0001] The utility model relates to the technical field of measuring line tightening, in particular to a convenient-to-use land surveying and mapping measuring line tightening device. Background Art

[0002] In the field of land surveying and mapping, accurate measurement is the basis for ensuring land planning, development and management. Various measuring lines are often used in the measurement process, such as tape measures, steel tape measures, etc. After searching, the Chinese patent authorization number CN219156137U discloses a convenient land surveying and mapping measuring line tightening device, which includes a cylinder, an observation frame is provided on the top of the outer edge of the cylinder, an H-shaped column is slidably installed on the outer edge of the cylinder, a groove for the H-shaped column to slide is provided on the cylinder, the inner groove of the H-shaped column is engaged with the cylinder, and a ring is constructed on the outer side of the H-shaped column. The column and the ring are jointly provided with a circular hole connected to the interior of the cylinder. The bottom end of the H-shaped column is constructed with an arc rod that fits the outer edge of the cylinder. The bottom end of the arc rod is constructed with a vertical plate. One end of the cylinder is threadedly connected to a screw cover, and a grip is installed on the screw cover. A long rod is installed in the cylinder. The land surveying and mapping measurement line tightening device can change the winding position of the measurement line at any time, which is more convenient; it can also clean the measurement line and dry grass or leaves that are stuck during measurement; and it is convenient to clean or replace it later.

[0003] The convenient-to-use land surveying and measuring line tightening device in the above-mentioned patent has the following shortcomings: an H-shaped column is slidably installed on the outer edge surface of the cylinder, and the measuring line passing through the circular hole is restrained by the H-shaped column and slides on the cylinder, which is convenient for winding up, and can avoid the measuring line from being concentrated in one part when tightening. However, when the H-shaped column is working, it needs to be moved manually all the time, resulting in the user having to operate the winding process all the time, which is relatively inconvenient. For this reason, a convenient-to-use land surveying and measuring line tightening device is designed. Utility Model Content
