And, the second clip body 1466b is connected to the second holding jaw 1464 and is inclined outward toward the lower side to be connected to the first clip body 1466a.

The clip body 1466 of each embodiment further includes a clip manipulation unit 148.

The clip manipulation unit 148 is provided to deform any one or more of the upper end and the lower end of the clip body 1466 of each embodiment to open in mutually opposite directions.

The clip manipulation unit 148 protrudes from one or more of the lower and upper ends of the clip body 1466.

A worker grips the protruding clip manipulation unit 148 to deform the corresponding clip body 1466 so that the corresponding locking protrusions 1462 and 1464 can be seated in or separated from the corresponding locking holes 142 and 144 .

And it further includes a sealing part 170 for sealing between the upper frame 112 and the lower frame 124 of the two adjacent single bodies 110 and 120 .

The sealing part 170 is composed of a first sealing installation groove 172, a second sealing installation groove 174, and a sealing ring 176.

The first sealing installation groove 172 is formed at the lower end of the lower frame 114 , 124 , 134 of the corresponding single body 110 , 120 , 130 .

In addition, the second sealing installation groove 174 is formed on the upper end of the upper frame 112, 122, 132 of the single body 110, 120, 130 to correspond to the first sealing installation groove 172.

The sealing ring 176 is installed in the first sealing installation groove 172 and the second sealing installation groove 174 .

The temperature control unit 900 controls the circulation unit 500 to circulate the gas in the sampling space 102 1 to 3 minutes before sampling by the sampling unit 200 .

Accordingly, as each component included in the gas of the sampling space 102 is uniformly distributed throughout, the effectiveness of the sample can be improved.

In addition, the temperature control unit 900 controls one or more of the first sampling unit 210, the second sampling unit 220, and the third sampling unit 230 to collect samples, respectively.

Accordingly, samples of the lower sampling space 102a, the middle sampling space 102b, and the upper sampling space 102c can be sampled, so that samples can be collected by height.

The temperature control unit 900 controls the door driving unit 610 to open and close the chamber doors 154 and 156 at intervals of 25 to 35 minutes.

Accordingly, the collection space 102 is ventilated to prevent incorrect sample collection.

In addition, as shown in FIG. 10, the chamber body 100 is further provided with a side door 180.

At least one side door 180 is provided on the side surface of the chamber body 100 to open and close the sampling space 102 in the lateral direction.

Accordingly, outside air can be introduced or discharged in a lateral direction, and the sampling unit 200 located in the sampling space 102 can be managed.

It is natural that the side door 180 is rotated by a hinge or slid by a rail, and can be automatically opened and closed by a motor and a cylinder.
