Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instruments, in particular to a portable surveying and mapping instrument supporting device. Background Art

[0002] Surveying and mapping instruments are instruments and devices designed and manufactured for surveying and mapping operations, such as data collection, processing, and output. They are various instruments required for orientation, distance, angle, height, mapping, and photogrammetry required for surveying work in the planning, design, construction, and management stages of engineering construction. Types include: theodolite, level, plane table, total station, and gyrotheodolite. When a surveying and mapping instrument is used, a supporting device is required to support it to facilitate surveying and mapping work.

[0003] A Chinese patent discloses a portable surveying and mapping instrument support device (authorization announcement number CN217762909U). The support mechanism of the patented technology is an umbrella-shaped mechanism. The retractable rod moves with the moving groove inside the rotating rod. The fixing needle can be inserted into the soil. The fixing mechanism cooperates with the supporting mechanism to fold the supporting mechanism. The clamp ring squeezes the screw rod to fix the supporting mechanism. The screw rod set in the middle can rotate with the support plate to achieve the purpose of moving up and down, pushing the top plate up and down to arbitrarily raise the height of the equipment. However, the above-mentioned mapping instrument support device is a metal structure as a whole. The weight of the support device is relatively large, which is not conducive to the portability of carrying. The unfolding and adjustment operation of the support structure is relatively laborious, which is not conducive to the convenience of use. Therefore, those skilled in the art provide a portable mapping instrument support device to solve the problems raised in the above-mentioned background technology. Utility Model Content
