The utility model relates to a convenient pressure measuring sampler used for carrying out measurement of pressure and sampling operation to the production wellhead of an oil field at all seasons, which is formed by orderly connecting an external steel jacket body, a piston connecting rod, a reversing indicating mechanism, a transmission mechanism and a direction adjustable sampling station; a handle transmission rod is artificially pushed to cause the piston connecting rod to move axially forward and backward in the external steel jacket body; the liquid interface in a steel jacket is extruded, and the handle transmission rod is turned to cause the piston connecting rod to turn in the radial direction in the external steel jacket body by communicating a drainage groove in the steel jacket, a diversion groove on a piston rod and diversion holes on the external steel jacket body; the reversing indication positioning puts into operation, which ensures that the wellhead measurement of pressure and sampling operation have the advantages of simplicity, labour saving, safety, direct-viewing and convenience.
