Abstract:
1. A specimen holder comprising: a body; a specimen mounting part formed at an end of the body for fixing a specimen; an elastic 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; and 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 top portion having a lever protruding outward, the support top 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 movable push rod connected with the elastic member; a lever connected with the push rod and being rotatable on a central shaft; a specimen pressing plate connected to an end portion of the lever for fixing one surface of the specimen; a lever spring connected to one side of the lever; and a fixing jaw formed on a specimen mounting space part where the push rod, the lever, the lever spring and the specimen pressing plate are arranged, the fixing jaw being adapted for fixing an other surface of the specimen, 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 push rod moves in such a manner that a space where the lever is rotatable is formed in the specimen mounting space part, the lever is rotated in one direction by elasticity of the lever spring applied to one side of the lever, and the specimen pressing plate is moved by the rotating lever, such that a first space is formed between the moved specimen pressing plate and the fixing jaw, wherein in the case that the body is separated from the stand after the specimen is mounted in the first space, the push rod is moved by elasticity of the elastic member, the moved push rod rotates the lever in an other direction, the specimen pressing plate is moved by the rotated lever, and the moved specimen pressing plate fixes one surface of the specimen, wherein the specimen is fixed in the first space in such a manner that the cross section of the specimen faces upward, and the user can observe the cross 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 push rod 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 push rod is caught to the retaining protrusion, such that the lever is rotated, wherein one side of the first grip 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.
