The utility model provides a rock core fixing and clamping instrument, belongs to the technical field of petroleum geology, and solves the problem that the conventional visible rock core clamping devices are not good in sealing effect. The rock core fixing and clamping instrument comprises a transparent rubber cylinder; an adjusting plunger piston and a stopping plunger piston are plugged at the two ends of the transparent rubber cylinder respectively; an upstream sealing disc is in bolted connection with the outer end of the adjusting plunger piston; a sealing ring I is arranged between the adjusting plunger piston and the upstream sealing disc; a downstream sealing disc is in bolted connection with the outer end of the stopping plunger piston; a sealing ring II is arranged between the stopping plunger piston and the downstream sealing disc; a glass pipe and an observation pipe are arranged between the upstream sealing disc and the downstream sealing disc; the two ends of the glass pipe and the observation pipe are propped against the end surfaces of the upstream sealing disc and the downstream sealing disc respectively; an adjusting sleeve pipe is in bolted connection with the outer end of the adjusting plunger piston; one end of the observation pipe, the upstream sealing disc and the adjusting sleeve pipe are fixed through an upstream pressing cap; the other end of the observation pipe and the downstream sealing disc are fixed through a downstream pressing cap. The rock core fixing and clamping instrument has the advantages that the rock core fixing and clamping instrument is good in sealing effect.
