Abstract:
1. A specimen holder comprising: a body; a specimen mounting part formed at an end of the body for fixing a specimen; an elasticity member located inside the body; a stand detachably joined with the body; and a hand-grip part formed at an end of the body, wherein the stand comprises: a base part forming a lower part of the stand; a joining part protrudingly formed on the upper face of the base part and having a through hole to which at least a part of the specimen mounting part is inserted; a support protrudingly formed on the upper face of the base part; and a retaining member connected with the joining part and having a retaining protrusion, wherein the support comprises: a support prop forming a lower part of the support; and a support to portion having a lever protruding outward the support to portion being joined with the support prop by a support screw and being rotatable on the support screw within a range of a predetermined angle, wherein the specimen mounting part comprises: a first grip part located at an end portion of the specimen mounting part for fixing one side of the specimen; and a second grip part movably connected with the elasticity member for fixing an other side of the specimen using elasticity of the elasticity member, wherein the second grip part comprises: a flat plate for fixing the other side of the specimen; and a push rod connected with the elasticity member, wherein in the case that the body is joined to the stand and at least a part of the specimen mounting part is inserted into the through hole, the second grip part moves to compress the elasticity member and a first space is formed between the first grip part and the moved second grip part, wherein in the case that the body is separated from the stand after the specimen is mounted in the first space, the second grip part is moved by elasticity of the elasticity member and the moved second grip part fixes the other side of the specimen, wherein the specimen is fixed in the first space in such a manner that a top section of the specimen faces upward, and the user can observe the top section of the fixed specimen using a scanning electron microscope, wherein the retaining protrusion stops at least a part of the through hole formed in the joining part, wherein the second grip part has a stepped portion protruding outward, wherein in the case that the body is joined to the stand and at least a part of the specimen mounting part is inserted into the through hole, the stepped portion formed on the second grip part is caught to the retaining protrusion, such that the second grip part is moved, wherein one side of the first rip part getting in contact with one side of the specimen is inclined at a first angle, and one side of the flat plate getting in contact with the other side of the specimen is inclined at a second angle, wherein at least a part of the hand-grip part is held on the upper face of the support, and wherein when a power to press the lever is applied, the support top portion lowers down while rotating on the support screw by the power applied to the lever, and the body joined to the stand is separated from the stand using the lowered support top portion.
