Summary:The utility model discloses a portable crushing sampler for geotechnical investigation, which comprises a driving unit, a hand rack is mounted on the driving unit, the bottom end of the driving unit is connected with an impact head, and the bottom end of the impact head is connected with a sampling drill cylinder; by designing the driving gear set, the mounting plate, the adjusting screw cylinder, the adjusting stud, the tooth frame and the handle, the bottom end of the tooth frame is in contact with the ground of a rock-soil layer during sampling, when the sampling drill cylinder and the driving unit descend synchronously, the tooth frame slides upwards relative to the mounting cylinder, and after sampling is completed, the tooth frame is driven to move upwards. At the moment, the driving gear set only needs to be rotated through the handle, the driving gear set and the tooth frame are in meshing transmission, and therefore the installation barrel is driven to slide upwards on the tooth frame, the sampling d
