摘要 一種棘輪扳手,其包括一本體、一棘輪、二掣動塊、二彈性件、一換向件;而將其掣動塊材料強度製成大於棘輪材料強度,提供以該棘輪扳手作扳動操作過程中,若施力超過棘輪之棘齒與掣動塊之齒部相嚙合處所限定與能承受之扭力而發生崩牙時,掣動塊之齒部將瞬間與棘輪位於經崩牙後方呈完好之棘齒作再次嚙合定位,達到確保操作者作業及人身安全效果。 A ratchet wrench comprises a main body, a ratchet, two detents, two elastic members, and a switch knob. The strength of the material of the detents is greater than that of the material of the ratchet. During the operation of the ratchet wrench, if the applied force is greater than the limit torsional force of the meshing portion between the teeth of the ratchet and the toothed portion of the detent to damage the teeth, the toothed portion of the detent will be instantly engaged with the intact teeth of the ratchet, located behind the damaged teeth, to be positioned again, thereby ensuring the safety of the operator.
