The invention discloses a general clamp for abrasive flow polishing of a complicated hole surface. The general clamp comprises a clamp body and one or more embedded modules; the clamp body is provided with uniformly distributed threaded holes in the peripheral direction; the clamp body comprises a lower pressing plate, a sleeve, an upper pressing plate and a sealing ring; the upper pressing plate and the sleeve are connected in a fastened manner; the lower pressing plate is connected with the sleeve; the upper pressing plate is provided with embedded module connecting holes and abrasive flow channel holes; the embedded modules are arranged in the clamp body; the embedded modules are detachably connected with the upper pressing plate in a fastened manner; the embedded modules compresses a non-polishing surface of a polished workpiece; the upper pressing plate is provided with the embedded module connecting holes uniformly distributed in the peripheral direction, and the embedded module connecting holes are used for connecting with different embedded modules; the abrasive flowing channel holes of the upper pressing plate are axially parallel to the polishing surface of the polished workpiece; the abrasive flow circulates in the abrasive flow channel holes in the part, which is not pressed and covered, of the upper pressing plate; when the surface of the polished workpiece is a curved surface, a columnar surface or a hole parallel to the direction of the abrasive flow, the embedded modules of corresponding shapes are replaced and recombined according to the appearance surface of the polished workpiece.
