A ratchet opener comprises a rod body; a ratchet device having a seat; a top surface of the seat having two axially grooves; each groove being installed with an elastomer and a ratchet block; an adjusting sheet placing above the seat; and a ratchet sheet being installed above the adjusting sheet. Each ratchet block has a teethed inclined surface; the teeth surfaces of the two ratchet blocks are symmetrical to a center of the seal. A center of the adjusting sheet is installed with a second via hole; and the ratchet block is installed with a non-round bucking hole corresponding to the cylinder at the lower end of the rod body. In use, by controlling the adjusting sheet, the objects of undirectional, bidirectional, and idle rotations are achieved. The operation is easy.
