[0001] The utility model relates to the technical field of engineering surveying and mapping equipment, in particular to an auxiliary fixing device for an engineering surveying and mapping instrument. Background Art

[0002] As we all know, various measuring instruments are used in engineering, but the three most important ones are total station, theodolite and level. The total station consists of an electronic theodolite, a photoelectric distance meter and a data recorder.

[0003] The patent with application number CN202120071258.6 discloses an auxiliary fixing device for an engineering surveying instrument, including a base, a mounting base, a bottom plate, a top plate and a surveying instrument body, the bottom end of the surveying instrument body is fixedly connected to the bottom plate, the bottom plate is connected to the turntable, the turntable is connected to the mounting base through a rotating shaft, the bottom end of the mounting base is fixedly connected to a moving block, a first motor is fixedly installed in the mounting base, the top end of the rotating shaft is vertically inserted in the center position of the lower end surface of the turntable, the bottom end of the rotating shaft passes through the mounting base and is connected to the motor output shaft at the top end of the first motor; a moving groove for installing a first threaded rod is opened on the top plate, the moving block is located in the moving groove, the moving block is sleeved on the first threaded rod and threadedly matched with the first threaded rod, one end of the first threaded rod passes through the top plate and is fixedly connected to the knob; the top end of the base is connected to the top plate through a push rod.

[0004] Although the device can adjust the position of the surveying instrument body in a short distance, the top plate of the device is fixed to the base by a push rod, so the swing direction of the top plate is fixed, and the surveying instrument body can only move in the installation direction of the top plate. It cannot be adjusted in multiple directions according to actual conditions, such as adjusting the position of the surveying instrument body to the left or right. Therefore, its practicality is not very good and there is room for improvement. Utility Model Content
