を再利用するためのホルダ。[Claims for Utility Model Registration] (1) In a holder for reusing a used microtome blade whose sharpness has deteriorated due to use for general cutting work such as a trimming knife: A rod-shaped holder body, From one end in the longitudinal direction on which the blade is attached, it is cut parallel to the longitudinal side of the rod-shaped holder body to a predetermined position with a width slightly wider than the blade width of the blade, and penetrates from the upper surface to the lower surface. At a position slightly apart from one end of the mounting side of the holder main body, a split groove is provided along the central axis plane, parallel to the longitudinal axis, inclined downwardly toward the mounting side end of the blade, and penetrating vertically. an inclined hole obliquely intersecting with the split groove, and a groove located at a position midway between the mounting end and the inclined hole in the longitudinal direction of the holder body, at right angles to the central axis plane, and separated by the split groove. A holder body having a loose hole in one width half of the holder body and a threaded hole in the other half that is threaded and provided across the split groove; and a tightening bolt: Insert the blade from the open end of the split groove that is the front end of the holder body until it reaches the inner circumferential surface of the inclined hole on the back side into which the holder body is inserted, and then tighten it. When fixed with a bolt, the back of the blade is in contact with the outer periphery of the tightening bolt, and the cutting edge of the blade is positioned approximately parallel to the lower surface of the holder main body, flush with the lower surface, or slightly recessed. The torque when cutting the tissue is due to the frictional force between the split groove and the side surface of the blade, and the engagement between the lower end corner of the inserted blade on the back side and the inner peripheral surface of the inclined hole. A holder for reusing a used microtome blade, characterized in that the blade is held without rotating. (2) The holder according to claim 1, wherein the holder main body has a pin hole extending further inwardly from the screw hole in the longitudinal direction thereof and extending substantially parallel to the screw hole; a pin that is inserted and fixed in a fit, the back of the blade contacts two points on the outer periphery of the tightening bolt and the outer periphery of the pin,
The lower end corner of the inserted blade on the back side engages with the inner periphery of the inclined hole, and the cutting edge of the blade is substantially parallel to and flush with the lower surface of the holder main body,
Or, the position may be slightly retracted, and with the tightening bolt tightened, even if a torque in the opposite direction to that at the time of cutting is accidentally generated, the frictional force between the split groove and the blade and the above-mentioned A holder for reusing a used microtome blade, characterized in that the blade is received by a pin and is safely held without rotating toward an operator's finger.
