The utility model belongs to the technical field of oil exploitation equipment, and discloses a pushing and setting nipple of a formation tester. Comprising a flat pup joint base body, a probe assembly embedded in the pup joint base body, supporting arms located on the two sides of the probe assembly, a hydraulic pipeline and a hydraulic control normally-open valve located between an open probe pipeline of the probe assembly and a sample pipeline of the probe assembly. Wherein the formation tester pushing and setting nipple has a sampling and pressure measuring mode: a probe assembly and a supporting arm extend out of a nipple base body in opposite directions under the hydraulic action of a pressure oil pipeline of a hydraulic pipeline, and a hydraulic control hydraulic control normally-open valve in a probe pipeline is opened to disconnect a sample pipeline and an outlet of the hydraulic control normally-open valve; in the pressure relief mode, the probe assembly and the supporting arm are oppositely retract
