Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping equipment, in particular to a surveying and mapping instrument support for planning. Background Art

[0002] Surveying and mapping instruments refer to instruments designed and manufactured for surveying and mapping operations and used for data collection, processing and data output. In order to facilitate the storage of surveying and mapping instruments, surveying and mapping instruments often need to be used with surveying and mapping instrument supports. The position of the surveying and mapping instrument supports needs to be fine-tuned according to actual usage requirements during use. Surveying and mapping instruments are often used for surveying and mapping in urban and rural planning work. With the advancement of the times and the development of science and technology, the requirements for the accuracy of construction surveying and mapping are getting higher and higher.

[0003] In contrast, a Chinese patent with announcement number CN216923740U discloses a surveying instrument support for urban and rural planning, which is characterized in that it includes a support, an adjusting device, a U-shaped box and a clamping device. The lower end face of the support is hinged with an adjusting leg. The adjusting device includes a sleeve and a rack that are interlaced and connected. The sleeve is vertically embedded in the center of the support. A gear that meshes with the rack is rotatably arranged inside the sleeve. An adjusting plate is fixedly arranged on the upper end of the rack. The U-shaped box is rotatably arranged on the adjusting plate through a bearing. Adjusting bolts are transversely threaded on both sides of the U-shaped box. A side plate is inserted on the right side of the U-shaped box. Connecting blocks are symmetrically fixedly arranged on the side plates. The clamping device is arranged on the side plates.

[0004] However, although the above patent conveniently realizes the vertical adjustment of the surveying height and the rotation adjustment of the surveying azimuth, it is not convenient to adjust the horizontal surveying position, which is inconvenient in actual use and calibration. In addition, there is only a single-point lifting support without limiting the instrument, which makes the instrument unstable. Therefore, a new device needs to be designed. Utility Model Content
