The utility model relates to a coupling, in particular to a two-section coupling with sliding blocks and pins. The coupling is widely applied to mechanical equipment, packaging equipment, transportation equipment and the like and comprises a left section fork, a two-head connecting section fork and a right section fork, wherein the left section fork is vertically clamped with the left end of the two-head connecting section fork through a left sliding block; the right end of the two-head connecting section fork is vertically clamped with the right section fork through a right sliding block; a left assembly hole is formed in the left section fork; and a right assembly hole is formed in the right section fork. The two-section coupling with the sliding blocks and the pins has a simple structure and high in assembly accuracy, and the service life is prolonged.
