Beschreibung
Zusammenfassung:	The utility model relates to a small probe system comprising a probe body, a sampler, a filter valve, a probe cylinder motion control hydraulic device, a filter valve motion control device, a probe cylinder, and a packer; the probe cylinder and the packer are arranged inside and on the top of the probe body respectively; the probe cylinder motion control hydraulic device drives a probe cylinder to move in the probe body axially along the probe body to achieve piston sliding; the sampler is disposed inside the probe cylinder; the filter valve is disposed at the top of the sampler; the filter valve motion control device drives the filter valve to open or close. The small probe system capable of reliably operating is compact in structure.
