[0002] Common surveying and mapping tools include levels, total stations, theodolites, and measuring rulers. Some precision levels, total stations, and other tools require support from brackets when in use. Common brackets are tripods and quadrupeds. These brackets have a certain size and weight. If the inspection position needs to be moved during use, the staff needs to lift the bracket and move it, which is inconvenient to move. In addition, the bottom structure of the bracket currently used is single and cannot be adjusted according to the specific conditions of the supporting ground. For example, on some smooth or soft ground, the support stability of the bracket is insufficient.

[0003] Therefore, a portable surveying and mapping tool that is easy to move and has stable support is needed. Summary of the Invention

[0013] By arranging an adjustment slot on the telescopic plate, the support frame is installed on one side of the adjustment slot. The support frame consists of a support plate and a base plate. A screw is arranged on the upper end of the support plate and passes through the adjustment slot. The support plate is fixed to the telescopic plate by squeezing and twisting the nut. The bottom of the support plate is sleeved with the base plate. When supporting the surveying and mapping instrument, the surveying and mapping personnel can move the support plate up and down on the inner side of the adjustment slot to adjust the height of the base plate, so that the base plate is stably supported on the ground, which is easy to operate. In addition, the support frame is tightened and fixed by screws and nuts, which can be easily disassembled and stored.

[0014] At the same time, the main body of the base plate is composed of a conical plate. When the base plate is erected, the pointed end is supported on the ground, which provides stable support on some rugged ground. When used on smooth ground, the conical plate can be rotated horizontally so that the conical plate fits the ground, increasing the contact area and friction with the ground. The support is flexible, convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS
