The present invention relates to a hand-holding original-state pillar collecting device belonging to the technical field of drilling, which comprises a drilling barrel, a base seat, a connection seat and a drilling rod, wherein the connection seat and the base seat are respectively arranged at both ends of the drilling barrel, and the drilling rod is connected with the connection seat. The drilling barrel is combined by two semi circles through grooves mutually engaged in a sliding way. When compacted soil samples are collected, two parts of a barrel body can be separated to obtain better original-state soil samples. When loose soil samples are collected, the drilling barrel can be directly used as a container to study and test the performance of original soil, while soil does not need to be taken out, and thus, the damage for original-state soil samples is avoided. A plurality of drilling barrels can be superposed to form required original-state pillars, so not only original-state pillars can be collected well, but also the collected original-state pillars are convenient to move and do other follow-up work. In a use process, soil sections do not need to dig, and original-state soil samples which are required to have deep inner sections can be obtained. Digging work for collecting field original-state soil samples is reduced.
