TECHNICAL FIELD

[0001] The utility model belongs to surveying and mapping marking technical field, concretely relates to a house property surveying and mapping point position marking tool. BACKGROUND

[0002] In the field of house property surveying and mapping, point position marking is a crucial link, which is directly related to the accuracy of surveying and mapping results and the precision of subsequent engineering construction. Traditional house property surveying and mapping point position marking tools, such as centering rods, as the main auxiliary tools for surveying and mapping personnel when conducting house property surveying and mapping, bear multiple functions such as determining measurement point positions, assisting in measurement, and marking point positions.

[0003] With the rapid development of modern surveying and mapping technology and the continuous improvement of surveying and mapping requirements, the traditional centering rod gradually exposes some obvious defects and deficiencies in actual application. The traditional centering rod has many inconveniences when in use. After finding the measurement point position, the surveying and mapping personnel need to bend down and manually move the centering rod, and then make a mark on the corresponding point position. Such an operation mode not only increases the labor intensity of the surveying and mapping personnel, but also affects the continuity and fluency of the surveying and mapping work. Especially in some complex or narrow measurement environments, the surveying and mapping personnel may need to frequently bend down, stand up, and move the centering rod, which not only reduces the surveying and mapping efficiency, but also increases the risk and difficulty of the surveying and mapping work. Since the surveying and mapping personnel need to manually mark the measurement point position, the accuracy and clarity of the mark are often affected by the personal habits and operation skills of the surveying and mapping personnel. At the same time, manual marking is easy to cause the shift or blur of the mark position, thereby affecting the accuracy and readability of the surveying and mapping results.
