Claim:
Ratchet socket for fitting onto a screwed member, the ratchet socket being drivable by a tool to wrench the screwed member, the ratchet socket comprising: a cylindrical main body; and at least one ratchet mechanism disposed in the main body, the main body being formed with a circular hole and a through hole in which the ratchet mechanism is disposed, the circular hole being formed in the main body, the through hole from one side to the other side passing through a section of the main body near the outer circumference thereof, the through hole communicating with the circular hole; said ratchet mechanism including: a ratchet wheel rotatably disposed in the circular hole, an outer circumference of the ratchet wheel being formed with continuous teeth; a dog member having an elongated body and two engaging sections at two ends of the elongated body, inner sides of the engaging sections being formed with multiple teeth for engaging with the teeth of the ratchet wheel, the dog member being movably accommodated in the through hole, the two engaging sections being such respectively positioned at two ends of the through hole that the two engaging sections cannot be at the same time engaged with the ratchet wheel; and a resilient hoop having two outward convex sections spaced from each other by a certain distance, the distance between the two convex sections being unequal to the distance between the two engaging sections, the resilient hoop being fitted around outer circumference of the main body to resiliently press the outer side of the dog member; when turning the resilient hoop to angularly displace on the main body, one of the engaging sections is moved outward from the through hole and positioned in one of the convex sections without engaging with the ratchet wheel, while the other engaging section is resiliently pressed by the body of the resilient hoop to move into the through hole and resiliently engage with the ratchet wheel, whereby by means of turning the resilient hoop, the driving directions of the ratchet mechanism is switchable.
