Vessel holder fixed with conical screw
The present invention relates to a vessel holder fixed with a conical screw for use in a biological microscope or the like, and more particularly, to an improved vessel holder fixed with a conical screw to be accurately fixed to a reference side without a change in position with respect to impact vibration while allowing the vessel holders to be closely attached to an upper surface of the stage with only one screw, thereby improving usability, cell observation efficiency and accuracy.
1 . A vessel holder fixed with a conical screw, which is used for a stage assembly comprising a stage having a holder groove and a vessel holder seated on the holder groove, characterized in that
one side surface of the holder groove is a reference side, a wedge insertion groove is formed in the reference side, and a screw opening is formed on the holder groove opposite to the reference side;
wherein one end of the vessel holder is formed with a protruding wedge inserted into the wedge insertion groove, and a screw hole is formed on the vessel holder opposite to the protruding wedge; and
wherein a fixing screw is fastened to the screw hole and the screw opening.
2 . The vessel holder fixed with a conical screw of claim 1 ,
wherein the screw hole has a cone-shape, and a lower part of a screw head of the fixing screw is formed in a conical shape; and
wherein even if the protruding wedge is fully inserted into the wedge insertion groove, a disparity distance does not become ‘0,’ so the assembly is completed at an intermediate point where it is not completely united.
3 . The vessel holder fixed with a conical screw of claim 1 ,
wherein the wedge insertion groove is formed recessed inward on the face of the reference side, and the protruding wedge has a shape corresponding to the shape of the wedge insertion groove.
4 . The vessel holder fixed with a conical screw of claim 3 ,
wherein both ends of the protruding wedge are diagonally cut to form inclined surfaces, and a tip width of the protruding wedge is smaller than a width of a wedge insertion groove.
5 . The vessel holder fixed with a conical screw of claim 1 , further comprising: a presser at a distance from the screw hole of the vessel holder, wherein the presser is configured to be axially fixed to an upper surface of the vessel holder and to be pivotable within a certain angle range.
