A sampling apparatus of a boring machine comprises a latch unit(20), a stopping unit(30), an inner pipe, and an auxiliary boring unit. The latch unit is inserted in a drill external pipe(12) having a bit(11) at the end and has a coupler for assembly with the drill external pipe. The stopping unit is connected with the latch unit through a spindle unit(31) and prevents the sampling device from dropping down. The inner pipe is supported by a holder(40) which is vertically movable and rotative with regard to the spindle unit. The auxiliary boring unit is installed at the end of the inner pipe. A torque transmitting unit is installed at the end of the inner pipe and transmits the torque of the drill external pipe to the inner pipe.
