The utility model discloses a special sampling machine for preparing a plastic pipe hot melting butt joint tensile sample. The special sampling machine comprises a power motor, a transmission assembly, a drilling assembly and a clamp assembly, wherein the transmission assembly comprises a drill bit lifting mechanism and at least two universal couplings; the drilling assembly comprises at least two drill bits and a drill bit regulating mechanism; each drill bit is mounted on a base of a supporting seat; the universal couplings of the transmission assembly are connected to the drill bits one by one; the power motor is arranged above the supporting seats; the supporting seat are sued for adjusting the motion in the vertical direction through the drill bit lifting mechanism; power of the power motor is distributed onto each universal coupling through a belt and a gear transmission mechanism; the clamp assembly is arranged below the drilling assembly. The special sampling machine solves the defects of low efficien
