Crucible support for ash content determination

The invention relates to a crucible support for ash content determination. Crucible placing positions (2) are located inside a support body (1) of the crucible support, support legs (3) are arranged at the bottom of the support body (1), and at least two clamping parts (4) are arranged inside the crucible placing positions (2). Each clamping part (4) comprises an upper clamping sheet (41) and a lower clamping sheet (42) which are hinged. The lower clamping sheets (42) are further hinged to the inner walls of the crucible placing positions (2). The upper clamping sheets (41) are provided with strip-shaped holes (43), limiting rods (44) are arranged on the inner walls of the crucible placing positions (2), and the limiting rods (44) are inserted in the strip-shaped holes (43). The support body (1) is further matched to be provided with a drawing handle (5) which is arranged in a split mode. A crucible base (51) is arranged at the end of the drawing handle (5), and a protrusion part (52) is arranged on the upper portion of the crucible base (51) and protrudes out of the top of the drawing handle (5). According to the crucible support, crucibles at the specific positions can be conveniently taken out accurately, quickly and safely.
