[0020] When the present invention is in use, the push handle is pushed to push the device to the location where monitoring is required. At this time, the motor in the bottom stabilizing component is started to drive the output shaft to run. When the output shaft is running, the connecting rod will eventually drive the moving wheel to move up and down, and finally drive the moving wheel to be received in the housing, so that the base contacts the ground, increasing the contact area and stabilizing the device.

When sampling the air, the air enters through the air intake plate, and then enters the adsorption plate. The adsorption plate absorbs impurities such as dust in the inhaled air to prevent it from entering the air collecting box column and affecting the measurement results. At the same time, when the air runs along the air intake plate, the air guide fan assists the air entering the device to run. After that, the adsorbed air blows the rotating partition to run along the surface of the partition seat. When the rotating partition runs to a certain position, it collides and contacts with the telescopic push rod, which is limited by the elastic force generated, and reacts to the rotating partition to return it to its original position. When the air collecting box column collects the air to be monitored, the partition of the rotating partition is used to prevent the air in the air collecting box column from dispersing.

[0022] When the present invention is in use, the engine in the lifting component is started, driving the output rod to run, and finally when the lifting rack is running, it will drive the extrusion arc plate to run, and the extrusion arc plate will drive the connecting oblique rod to run, and the connecting oblique rod clamps the gas collecting box column. The connecting oblique rod is placed obliquely to share the force when the device is running. At the same time, when the connecting oblique rod is running, the gas collecting box column is fixed by two elastic fixing plates, which can be more stable when collecting air. At the same time, the bottom lifting rod assists in driving the gas collecting box column to run. When the gas collecting box column is recovered, it will collide with the protection spring, so that it is protected by the elastic force generated by the protection spring during recovery.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The air guide runs, and then the adsorbed air blows the rotating partition 49 to run along the surface of the partition seat 48. When the rotating partition 49 runs, it will slide along the inner wall of the arc limit plate 50. When the rotating partition 49 runs to a certain position, it will collide and contact with the telescopic push rod 51, and limit it. The elastic force generated will react on the rotating partition 49 to return it to its original position. After the air collecting box column 42 collects the air to be monitored, the partition of the rotating partition 49 is used to prevent the air in the air collecting box column 42 from dispersing.At this time, in the lifting component 3, the engine 4 is started, driving the output rod 61 to run, and the output rod 61 will drive the output bevel gear plate 62 to run, and through the meshing action of the surface of the output bevel gear plate 62, the transmission bevel gear shaft 63 is driven to rotate along the inner wall of the gear shaft sleeve plate 64. When the transmission bevel gear shaft 63 runs, it will drive the vertical gear plate 65 to run, and the vertical gear plate 65 will drive the lifting rack 66 to move up and down along the inner wall of the rack sleeve plate 67 through the surface meshing action. At the same time, the auxiliary lifting rod 68 runs, and the auxiliary lifting rack 66 is lifted and lowered. When the lifting rack 66 runs, it will drive the extrusion arc plate 69 to run, and the extrusion arc plate 69 is driven to run. The arc pressure plate 69 will drive the connecting oblique rod 70 to operate, and the connecting oblique rod 70 will clamp the gas collecting box column 42. The connecting oblique rod 70 is placed obliquely to share the force during the operation of the device. At the same time, when the connecting oblique rod 70 is running, it will drive the elastic fixing plate 71 to operate, and the gas collecting box column 42 is fixed by the two elastic fixing plates 71, which can be more stable when collecting air. At the same time, the bottom lifting rod 73 assists in driving the gas collecting box column 42 to operate. When the gas collecting box column 42 is recovered, it will collide with the protective spring 74, so that it is recycled and protected by the elastic force generated by the protective spring 74.
