Detailed ways

The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

See Fig. 1-Fig. 2, is the structural representation of a kind of magnesium powder sampler of the present invention, comprises probe 1, sampling cylinder 2 and push rod 3, and described probe 1 is welded on sampling cylinder 2 front ends, offers sampling groove on sampling cylinder 2 21. The ejector rod 3 is set in the sampling cylinder 2, the head of the ejector rod 3 is provided with a discharge block 31, and the middle part of the ejector rod 3 is provided with a blocking block 32 corresponding to the sampling groove 21 on the sampling cylinder 2.

The probe 1 is a cone structure with a taper of 60°-80°.

The sampling cylinder 2 is made of stainless steel, and pressure rods are arranged on both sides of the top.
