Quick-release connecting device for clamp tool part

The invention provides a quick-release connecting device for clamp tool parts, which comprises a tool table, the top end of the tool table is connected with a primary positioning mechanism and a precise positioning mechanism, and the primary positioning mechanism and the precise positioning mechanism are mutually staggered to form a cross shape; the preliminary positioning mechanism comprises a first lead screw installed on the lower surface of the tool table and positioning blocks connected with the outer surfaces of the two ends of the first lead screw through nuts. The precise positioning mechanism comprises a second lead screw arranged at the top end of the first lead screw and installed on the lower surface of the tool table, and clamping seats connected with the outer surfaces of the two ends of the second lead screw through nuts, and the bottom ends of the clamping seats are slidably connected with the upper surface of the tool table. Movement of the clamp tool can be rapidly limited, limitation on the
