The proposed device for clamping a block apparatus (14) when grinding small glass bodies, particularly mechanically ground stones consists of a carrier (1) of the apparatus (14) that is vertically slidable within a casing (2) of the carrier (1), and guide rod (6) being slidably mounted inside the apparatus (14) casing (7) having at the spot of a shoulder contact orientation lands (18). The carrier (1) casing (2) is provided with two adjusting screws (12, 13) and the apparatus (14) carrier (1) has at its bottom side a base (15) having the form of a plate with three adjustable stops (3, 4, 5) and through holes (16) for free passage therethrough of guides (10, 11), which are on one side fixedly coupled with the guide rod (6) and being provided on the other side with thread and a dish-shaped nut (17), whereby between the nut (17) and the apparatus (14) carrier (1) base (15) there is arranged a compression spring (8, 9). The adjustable stops (3, 4, 5) form an isosceles triangle with respect to the working field (19) of sealing tools (20).
