description The utility model discloses an environmental gas collecting device, which belongs to the technical field of gas collecting equipment, and realizes free taking-out of a gas collecting mechanism by arranging a limiting mechanism among a first positioning ring, a second positioning ring and the gas collecting mechanism, thereby improving the convenience in gas collecting work. Meanwhile, after the gas collecting mechanism is used, the gas collecting mechanism is convenient to carry through a limiting mechanism, and the phenomenon that the gas collecting mechanism shakes during carrying can be avoided; a connecting rod is inserted into a collecting cylinder of the gas collecting mechanism, a piston is fixedly connected to the lower end of the connecting rod and makes contact with the inner wall of the collecting cylinder, and a sealing cover is arranged at the lower end of the collecting cylinder in a sleeving mode to enhance the gas tightness of the collecting cylinder and avoid gas leakage. And the opening at t
