The utility model provides a forward inlet and forward outlet combined motion mechanism for a core taking instrument. The forward inlet and forward outlet combined motion mechanism comprises a supporting seat, a thrust guide plate, a force bearing guide plate, a sliding block, a driving block, a connecting rod and a cylindrical pin. The force bearing guide plate comprises a horizontal guide groove, a vertical guide groove linear section and a vertical guide groove arc section. The driving block is connected with a via hole of the thrust guide plate through the connecting rod. The sliding block slides in the guide groove of the force bearing guide plate. When the driving block drives the thrust guide plate to slide in the chute of the supporting seat, the sliding block drives a motor to finish the rotating, forward-moving and swinging motion trail.
