The karst area shale gas opening sample testing device of claim 1, wherein: the working principle is as follows: when the device is used, the bottom plate (1) is pushed to the position of a shale gas sampling product through the push rod (4), then a plurality of first insertion pipes (5-4) are respectively inserted into the reserved sampling positions of a shale gas production pipeline, as the outer diameters of the first insertion pipes (5-4) are sequentially and gradually reduced from top to bottom, when the first insertion pipes (5-4) are inserted downwards, the first insertion pipes (5-4) are tightly attached to the gas production pipeline, then the first check valves (5-2) and the second check valves (6-3) are opened, the shale gas is sequentially conveyed into the buffer storage box (6-1) through the first insertion pipes (5-4), the telescopic pipes (5-3) and the connecting pipes (5-1), and as the density of the air is heavier than that of the shale gas, the air in the buffer storage box (6-1) is discharged into the waste gas collecting box (6-4) through the guide pipe (6-2), after a period of time, after the buffer storage box (6-1) and the waste gas collecting box (6-4) are filled with gas, the one-way valve (5-2) and the two-way valve (6-3) are closed, the air pump (7-1) is started and the one-way control valve (7-4) is opened, the shale gas in the buffer storage box (6-1) is pumped into the conveying pipe (7-2) by the air pump (7-1) and then is discharged into the one storage box (7-3) through the conveying pipe (7-2), when the one storage box (7-3) is filled with gas, the one-way control valve (7-4) is closed, and the two-way insertion pipe (7-6) at the upper end of the filled one storage box (7-3) is taken down from the sealing sleeve (7-5) for detection.
