12. soil VOCs processing instrument according to claim 11, it is characterised in that: the head space heating component (41) is to pass through
Entire body, so that after head space end of operation, head space needle assemblies (38) back movement described in two groups to a certain position, the sampling bottle
(1) it is fallen after the head space heating component (41) capable of being passed through.
13. soil VOCs processing instrument according to claim 12, it is characterised in that: the head space heating component (41) includes
Two pieces of heat blocks (42) staggered relatively and two pieces of support plates (44) being connected with the heat block (42) add described in two pieces
Heat block (42) can cross the support plate (44) with two pieces of consistent entire bodies in support plates (44) besieged city, the head space needle (48)
Head space operation is carried out to the sampling bottle (1).
14. soil VOCs processing instrument according to claim 13, it is characterised in that: the head space mechanism (37) further includes setting
The head space bracket (45) in head space heating component (41) side is set, the head space bracket (45) is used to support the head space and adds
Hot component (41) offers the opening (50) being connected with the head space heating component (41) on the head space bracket (45), and
The sampling bottle (1) falls after capable of passing through successively the head space heating component (41) and the opening (50).
15. soil VOCs processing instrument according to claim 14, it is characterised in that: two heat blocks (42) it is opposite
Raised (43) are provided on one side, it is described convex when in the sampling bottle (1) circulation to the head space heating component (41)
Playing (43) can be stuck at the bottle body (2).
16. soil VOCs processing instrument according to claim 11, it is characterised in that: the second limiting device described in every group includes
The second limited block (46) for being sleeved on second adjusting screw rod (40) is fixed on second limited block (46)
Postive stop baffle (47), when head space operates, postive stop baffle (47) relative motion to the head space heating component (41) and institute
It states between head space bracket (45) to stop falling for the sampling bottle (1), after head space, head space needle assemblies (38) described in two groups
When back movement is to a certain position, the postive stop baffle (47) is far from from the head space heating component (41), so that the sampling
Bottle (1) can be fallen after passing through the head space heating component (41) from the head space mechanism (37).
