The invention discloses a sampling device for greenhouse gas monitoring, which comprises a mounting box, a collecting box arranged in the mounting box, a piston plate arranged in the collecting box, a switching mechanism arranged on the right side of the piston plate, a gas inlet pipe arranged on the right side of the collecting box, and a gas outlet pipe arranged on the right side of the collecting box and rotatably connected with the switching mechanism, the collecting box and the mounting box. A power mechanism is arranged on the left side of the collecting box and fixedly connected with the mounting box, and an extending holding mechanism is arranged on the left side of the mounting box. The sweeping vibration mechanism is used for intercepting impurities in air entering the air inlet pipe and automatically cleaning the whole mechanism; the piston plate is driven by the motor to move in the collecting box to collect gas, and meanwhile, the gas inlet pipe can be controlled to rotate by 360 degrees all the
