Preferably, the fixed seat is fixedly connected with two stressing rods, and the two stressing rods are oppositely arranged and extend along the transverse direction. This optimization scheme is through setting up the power pole convenience and exert downwards and make the rotatory power of sampler barrel to the sampler barrel, makes the sample convenient and fast more.

As optimization, the force applying rod is further sleeved with a force applying pipe. According to the optimized scheme, the force arm to the sampling cylinder is increased by arranging the forcing pipe, so that labor is saved when the sampling cylinder is rotated; the stress application pipe is sleeved on the stress application rod, so that the stress application pipe is convenient to take down, and before soil is taken out from the sampling cylinder, the stress application pipe can be used as a tool to knock the sampling cylinder, so that the soil can be taken out more conveniently and rapidly, and the number of tools carried by workers is reduced.

Preferably, one end of the forcing pipe, which is far away from the fixed seat, is fixedly connected with a gripping ring. This optimization scheme makes things convenient for staff's gripping through setting up the ring of grabbing, and it is more convenient to use.

Preferably, the upper end of the piston rod is fixedly connected with a rotating handle. This optimization scheme has made things convenient for the operation to the piston rod through setting up twist grip, makes the sample operation more convenient.

The utility model has the advantages that: through setting up the sampler barrel lower extreme into along circumference closed pointed end to set up the external screw thread at the outer wall of sampler barrel, make the sampler barrel stretch into soil more conveniently, realize the sample operation, through the screw-thread fit of piston rod and nut, just can take out the soil in the sampler barrel when rotating the piston rod, improved the efficiency of sample operation by a wide margin.
