Manufacturing method for ratchet wrench, involves finishing reserved material at front end of ratchet lever using numerical control miller to form rib vertically extended between upper and lower front edges of recess formed on ratchet lever

摘要

The method involves reserving a portion of material at a front end of a ratchet lever (11) during the process of milling, and finishing the reserved material at the front end of the ratchet lever using a numerical control miller to produce a rib (113) vertically extended between upper and lower front edges of an open recess (112) formed on the ratchet lever.
