Description

Space protractor

Technical Field

The utility model relates to the technical field of space protractors, in particular to a space protractor.

Background

The protractor is an instrument for measuring an included angle, but when a common protractor measures the angle of an object in space, serious deviation can occur in measurement accuracy, and measurement is inaccurate.

The patent literature with the publication number of CN114577172A provides a space protractor, the device changes the traditional use mode that needs to look for the reference plane as the basis and then measure the space protractor through optimizing the setting of space protractor, reduce too complicated measuring step, improve into a simple structure and use more convenient protractor, the structural design has the angle measuring plate that can dismantle, it is more convenient to install and use and carry, angle modulation structure that can micro-control, can realize more accurate measurement, the footing that has many supporting modes is designed in addition, the applicable scope of working face is more extensive, should popularize and use.

Although the device beneficial effect is more, the device is bulky, and the transport is comparatively difficult during the use, and need adjust the stabilizer blade and keep the level when measuring, use too loaded down with trivial details, can greatly increased measuring time, reduced work efficiency. In view of this, we propose a spatial goniometer.
