Abstract
A ratchet tool test device includes a board having a hole and a recess which has a toothed inner periphery and shares a common axis with the hole. A pawl member has a shank rotatably extending through the hole and a plurality of extensions extend from the shank. Each of the extensions has teeth which are engaged with the toothed inner periphery. An engaging section is securely connected to the shank so as to be cooperated with a ratchet tool. When the ratchet tool is rotated, the teeth are moved over the toothed inner periphery in one direction.
