After the powder is poured out, the arc-shaped shielding sheet 113 is loosened, and the arc-shaped shielding sheet 113 is pushed back to the side of the sampling port 106 under the pushing of the arc-shaped spring 114. In this way, the drug powder in one of the sampling ports 106 can be taken out alone.

[0027] When the medicine powder is sampled by using the utility model, the staff inserts the sleeve 102 into the medicine sample by hand, then pulls the handle 101 to move upwards, the handle 101 drives the moving block 103, the connecting rod 104 and multiple shielding components 105 to move upwards, so that multiple arc-shaped shielding pieces 113 are dislocated with multiple sampling ports 106 and leak out the sampling port 106, at this time the return spring 107 is compressed, then the sleeve 102 is rotated, the medicine powder will enter multiple sampling ports 106 with different heights, then the handle 101 is loosened, the elastic potential of the return spring 107 can push the moving block 103 and the handle 101 to move downwards and reset, so that multiple arc-shaped shielding pieces 113 return to the side of the sampling port 106, the sampling port 106 is closed, then the sleeve 102 is removed from the medicine sample, and the sampling is completed; the arc-shaped guide shell 111 provides guidance for the movement of the arc-shaped spring 114 and the arc-shaped shielding piece 113, the arc-shaped shielding piece 113 is rotated along the surface of the sleeve 102, so that the arc-shaped shielding piece 113 moves away from the sampling port 106, at this time the arc-shaped shielding piece 113 will drive the arc-shaped slider 112 to move, the arc-shaped slider 112 will compress the arc-shaped spring 114, then the medicine powder in the sampling port 106 can be poured out, after the powder is poured out, the arc-shaped shielding piece 113 is loosened, the arc-shaped shielding piece 113 will return to the side of the sampling port 106 under the pushing of the arc-shaped spring 114; in this way, the medicine powder in one of the sampling ports 106 can be taken out alone; by the above-mentioned mode, the medicine powder at different depth positions of the medicine sample can be sampled at the same time, and the medicine powder sampling efficiency is improved. When the arc-shaped shielding piece 113 does not need to move away from the sampling port 106, the staff holds the knob 109 and rotates the screw rod 108 in the positive direction, the screw rod 108 drives the anti-skid pad 110 to approach the sleeve 102, until the anti-skid pad 110 abuts against the outer wall of the sleeve 102, so that the position of the connecting rod 104 can be limited, and then the positions of multiple shielding components 105 are fixed, avoiding that the handle 101 is mistakenly touched and causing the arc-shaped shielding piece 113 to move.
