The utility model discloses a high-precision casting and belongs to the technical field of castings. The connecting structure comprises a casting and a convenient connecting mechanism, wherein the convenient connecting mechanism is arranged in the casting; the convenient connecting mechanism comprises a connecting groove formed in the top of the bottom casting, an inserting ring fixedly connected with the top casting is clamped in the connecting groove, a plurality of evenly-distributed driving bins are formed in the bottom casting, and driving magnetic plates are arranged in the driving bins in a sleeving and sliding mode. And one side of the driving magnetic plate is fixedly connected with an inserting rod. The inserting rod can be conveniently driven to be inserted into or separated from the clamping groove through telescopic recovery of the compression spring and adsorption of magnetic force, then the two castings can be conveniently assembled and disassembled, compared with existing high-precision castin
