The invention will be explained in more detail in the following description in connection with the drawing The invention relates to a stopper holder for 40 läutert. a pouring ladle with a bottom outlet, the stops of which F i g. 1 shows an embodiment of the invention, Via a stopper rod with the aid of an actuating mechanism in which the toggle lever and the actuating element element is displaceable in the vertical direction. in the closed position of the plug in the extended position Of course, the bracket can also be used in dash-dot lines with pouring lines and with the stopper raised. basins and furnaces are used. 45 th lines are shown; A disadvantage of known plug holders and FIG. 2 and 3 give the cuts II-II and ΙΠ-ΠΙ their actuating elements consists in the fact that between F i g. 1 again while see the stroke of the stopper and the path of FIG. 4 shows the path of the Actuating elements an almost constant over-stopper rod and the swing at a loading settlement ratio is present; this makes it impossible to reproduce the correct stroke h and to calculate the lent to finely regulate the pouring stream. Rotary arm r is used for the upper swing arm. The invention is therefore based on the object, the pouring ladle 1, which is generally made of steel, a stopper holder with a lifting mechanism for the sheet metal, is depending on the temperature and fjn, at which a fine regulation of the pouring stream aggressiveness of the melts to be poured is also possible. 55 of a lining 2 made of ceramic material, e.g. B.
