AI Technical Summary
Existing surveying and marking devices have limited functionality and cannot simultaneously meet the needs of construction workers in the wood processing process for marking lines, drawing circles, and measuring angles. This results in construction workers having to carry multiple tools, which is inconvenient and prone to loss.
A surveying and marking device was designed, which combines a ruler, a disc, a circle drawing structure and a protractor. It achieves multi-functional operation through rotating connectors and a limiting frame, including straight line measurement, angle measurement and circle drawing.
It achieves comprehensive functionality, capable of simultaneously performing line measurement, angle measurement, and circle drawing. It is simple to operate and highly stable, reducing the inconvenience of carrying tools and the risk of loss.
