A ratchet device includes a body, a ratchet wheel unit, and a switching unit. The body has an outer peripheral surface, at least one slide slot formed in the outer peripheral surface, at least one first groove, and at least one second groove. The ratchet wheel unit includes a ratchet wheel sleeved on the body, at least one first pawl member inserted into the first groove, at least one second pawl member inserted into the second groove, and resilient members biasing the first and second pawl members to engage the ratchet wheel. The switching unit is sleeved on the body, and includes a pushing member disposed in the slide slot, and a switching member connected to the pushing member. Through operation of the switching member, the first or second pawl member can be separated from the ratchet wheel. |

1. A ratchet device comprising:
a body extending along an axis and having an outer peripheral surface disposed around the axis, at least one slide slot formed in said outer peripheral surface, at least one first groove in spatial communication with and located at one side of said slide slot, and at least one second insert groove in spatial communication with and located at the other side of said slide slot; a ratchet wheel unit including a ratchet wheel sleeved on said body, at least one first pawl member inserted into said first groove, at least one second pawl member inserted into said second groove, and a pair of resilient members disposed respectively within said first and second grooves, said ratchet wheel having a sleeve end sleeved on said body, and a work end opposite to said sleeve end, said sleeve end having an annular inner peripheral surface and a plurality of ratchet teeth disposed on said inner peripheral surface, said first pawl member having a plurality of first pawl teeth engageable with said ratchet teeth, said second pawl member having a plurality of second pawl teeth engageable with said ratchet teeth, said resilient members biasing said first and second pawl members toward said ratchet teeth; and a switching unit sleeved on said body and including a pushing member rotatable about the axis in said slide slot, and a switching member connected to said pushing member, said switching member being operable to rotate said pushing member in said slide slot so as to retract a selected one said first and second pawl members into a corresponding one of said first and second grooves. |
