High-precision intelligent air sampling instrument

The utility model is applicable to the technical field of air sampling equipment, and provides a high-precision intelligent air sampling instrument, an electric rod is electrified through a console switch, the electric rod extends upwards and drives a first bevel gear and a sampling instrument to be pushed out upwards, and when the electric rod reaches the highest height, the first bevel gear and a second bevel gear are in a meshed state; when the sampling instrument needs to sample and detect air in multiple directions or other directions, a motor is started through a control table, the motor drives a rotating rod to rotate, the rotating rod drives a second bevel gear to rotate, the second bevel gear drives a first bevel gear to rotate, and the first bevel gear drives a second bevel gear to rotate. The first bevel gear drives the sampling instrument to rotate through the connecting rod, when the sampling instrument rotates to a required angle, the motor is turned off, and the sampling instrument can sample a
