Abstract

A tool ratchet wheel device (3), including: a ratchet wheel head capable of wedging and transmission, being mounted to a lever head end having inner annular gears therein, the ratchet wheel head being pivotally provided therein with plural pawls having pawl teeth at both sides; a switch controlling the wedging directions of the pawls and inner annular gears at the same time, wherein each pawl is pivoted to the same pivot and the pawl teeth provided to its same side are arranged from each other at different gaps with respect to the pivot center, such that different wedging degrees are maintained between each pawl and the inner annular gears. While racing in the reverse direction, each pawl may straddle over the pawl teeth within the angular range of a single inner annular gear, and allows forward operative rotation of the wrench after each pawl straddles over. As such, by the arrangement with different gaps between neighboring pawl teeth of the pawls about the same pivot, the angular range which it is able to straddle over a single annular gear may be subdivided, so as to ensure optimum wedging strength by means of subdivided compensation, while providing additional selection of operative angles. This invention is truly industrial applicable.
