And , the stainless steel square tube can freely stretch and contract to be suitable for the sample test with different sizes.

, connecting end of the adjusting bolt with the fixed end head through a ball head, and arranging a nut at end.

And , an antiskid gasket is arranged on the surface of the fixed end, which is attached to the inner wall of the environment test chamber, so that friction is increased, the sample support is prevented from sliding off, and the fixed end is prevented from scratching the inner wall of the environment test chamber.

During sample testing, the length of the stainless steel square pipe is adjusted according to the size of a sample, the adjusting bolt is rotated according to the volume of the environment testing cabin, the sample support is fixed at a proper height in the environment testing cabin, the sample to be tested is placed into the sample clamping groove, the fixing bolt is adjusted to fix the sample to be tested, and when the two samples to be tested reach a parallel rear part, the test can be started.

The utility model has the advantages that:

1. the utility model discloses simple structure, simple to operate has detachability, can freely stretch out and draw back not unidimensional sample of adaptation and different volumetric environmental test cabins.

2. The utility model discloses can survey two samples simultaneously as required, also can only survey samples, still can increase the sample support according to the volumetric size of environmental test cabin simultaneously, survey a plurality of samples.
