[0002] Project cost is an important part of the construction process, which mainly refers to the process of surveying and counting the cost of the entire building. Various measuring instruments will be used in the surveying of the building, and the corresponding edges require surveying support devices. The existing support devices for on-site surveying of construction project costs, such as the support device for on-site surveying of construction project costs disclosed in application No. CN202220171922.9, have retractable and adjustable support feet, which can independently adjust the length of each support foot according to the complex terrain, thereby realizing auxiliary support for the support rod, and a fixed cone is provided, which can be rotatably adjusted to fix the angle of insertion in the soil, thereby further improving its adaptability to complex terrain and effectively maintaining the horizontal placement of the surveying device.

In particular, the existing support device lacks limit stops between the support rods, resulting in poor overall stability and easy tilting. For this reason, we propose a support device for on-site surveying and mapping of construction project costs to solve the above problems. Utility Model Content
