Specific embodiment
Embodiment 1:
Referring to Fig. 1, a kind of sampler, including sample collection piston cylinder 1, piston 2, sampling portion 3 and sub-sampling portion 4；
The piston 2 includes piston top 21, piston rod 22 and piston handle 23, and the piston top 21, piston handle 23 are set respectively
It sets at 22 both ends of piston rod, the piston top 21 is inserted into sample collection piston cylinder 1；
Aperture 11 is arranged in sample collection piston cylinder top 14；
The sampling portion 3 includes the first probe tube 31, the second probe tube 32, the internal diameter and first of second probe tube 32
The outer diameter of probe tube 31 is identical；Described first probe tube, 31 one end is connected with the aperture 11 on sample collection piston cylinder top 14,
And it is fixed on sample collection piston cylinder top 14, the other end is connected by screw thread with the second probe tube 32；Second probe tube
Screw thread is arranged in 32 outer surface；
The sub-sampling portion 4 includes casing 41 and rotating handle 42, and 41 one end of described sleeve pipe is fixed on rotating handle 42
On, the internal screw thread that other end setting matches with 32 outer surface thread of the second probe tube, the internal diameter of described sleeve pipe 41 takes with second
The outer diameter of sample pipe 32 is identical.
Embodiment 2:
