[0002] Surveying refers to the determination, collection, and mapping of the shape, size, spatial location, and attributes of natural geographical elements or man-made structures on the earth's surface. The term "surveying" literally means measuring and drawing. Field surveying requires specialized surveying instruments, which can quickly measure the area, distance, perimeter, and other data of any shape of land parcel. These instruments are suitable for measuring the area of ​​farmland, green spaces, forests, water bodies, tidal flats, and industrial areas. Surveying instruments are typically used with positioning supports to hold and fix their position.

[0003] Currently, surveying instruments are generally used in environments with uneven ground for measurement. The height adjustment of the surveying instrument support is difficult to operate, and the accuracy is not achieved, which affects the quality of the project. Therefore, an improvement has been made to a surveying support device. Utility Model Content

[0006] By adopting the above technical solution, when straight thread one and straight thread two are engaged, the sliding cylinder is fastened inside the support leg. By rotating the telescopic leg, the sliding cylinder is driven to rotate synchronously inside the receiving groove. When straight thread one and straight thread two are not engaged, the sliding cylinder can slide freely inside the receiving groove, which allows the height of the support leg of the bracket device to be adjusted. The bracket device has three legs, and each leg can be adjusted individually, so that the height of the base can be adjusted and the base can be kept level in uneven ground environments with high precision, ensuring the quality of the project.

[0007] As a preferred technical solution of this application, the outer diameter of the sliding cylinder is adapted to the inner diameter of the storage groove, and the outer diameter of the sliding cylinder is larger than the outer diameter of the telescopic leg.

[0008] By adopting the above technical solution, the sliding cylinder is prevented from detaching from the inside of the storage slot.

The three support legs are movably connected together by the cooperation between the stabilizing unit and the positioning seat, so that the angle of the support legs is not easy to change, the stability is strong, and the device is prevented from being unstable and tipping over.

[0013] As a preferred technical solution of this application, the stabilizing unit includes a disk, the top of which has three rotating slots, and a connecting rod is rotatably connected inside the rotating slots. The disk is movably connected to the positioning seat through the connecting rods.

[0014] By adopting the above technical solution, the three support legs are movably connected together through the cooperation between the disc, the rotating groove, the connecting rod and the positioning seat.

[0015] As a preferred technical solution of this application, a rotating rod is fixedly installed at the center of the lower surface of the mounting bracket, and a bearing seat is fixedly installed inside the base. The rotating rod passes through the bearing seat and is movably connected to the base.

[0019] As a preferred technical solution of this application, the telescopic leg, support leg, positioning seat, disc and connecting rod are all made of aluminum alloy.

[0020] By adopting the above technical solutions, aluminum alloy is a lightweight, high-strength, corrosion-resistant, and easy-to-process material. The surveying bracket made of aluminum alloy has the advantages of being lightweight and easy to carry, oxidation-resistant, and durable.

[0021] The beneficial effects of this application are: In this invention, when straight thread one and straight thread two are engaged, the sliding cylinder is fastened inside the support leg. By rotating the telescopic leg, the sliding cylinder is driven to rotate synchronously inside the receiving groove. When straight thread one and straight thread two are not engaged, the sliding cylinder can slide freely inside the receiving groove, thus allowing the height of the support legs of the bracket device to be adjusted.
