The beneficial effect is as follows: by placing the theodolite in the middle of the upper surface of the mounting plate, the mounting block is located in the inner cavity of the mounting groove, the mounting block is pre-fixed by using the mounting groove, the knob is pulled to move the clamping block out of the inner cavity of the clamping groove, and the square block enters the inner cavity of the square groove at the same time, the knob is turned to drive the screw rod to rotate, so that the first slider drives the limit rod to move, so that one end of the limit rod extends into the inner cavity of the limit groove, the mounting block is fixed, and the installation of the theodolite is completed. The operation is convenient and no tools are required.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the process of disassembling and assembling the theodolite, the existing geographic information engineering surveying and mapping device needs to manipulate multiple knobs to rotate and adjust multiple screws so that multiple limit rods are moved out of or inserted into the limit slots to realize the disassembly and assembly of the theodolite. However, the operation steps are complicated, which increases the time consumed in disassembling and assembling the theodolite, is not convenient for quick disassembly and assembly of the theodolite, and increases the operation workload of the staff;
